Answer:
Dividing Decimals
Step 1: Estimate the answer by rounding .
Step 2: If the divisor is not a whole number, then move the decimal place n places to the right to make it a whole number.
Step 3: Divide as usual.
Step 4: Put the decimal point in the quotient directly above where the decimal point now is in the dividend.
Step-by-step explanation:
Step 1. Turn the second fraction (the one you want to divide by) upside down
(this is now a reciprocal).
Step 2. Multiply the first fraction by that reciprocal
Step 3. Simplify the fraction (if needed)

Two step equation, I don’t know how to do the problem step by step. 3x+9=5. I know that the answer is -1 1/3 but I don’t know how
Answer:
Below
Step-by-step explanation:
1. 3x+9=5
2. 3x+9-9=5-9
3. 3x=-4
5. 3x/3=-4/3
6. -4/3
7. -1 1/3
Answer:
The answer is -4/3 or - 1 1/3
Step-by-step explanation:
3x+9= 5
-9 -9
3x = -4
/3 /3
Y= -4/3 or [tex]-1\frac{1}{3}[/tex]
Step 1: Add subtract 9 to both sides because you want to cancel out the 9 so you do the opposite of what is say's. For example, if it says 3x-9 add 9 or 3x+9 subtract 9 from both sides.
Step 2: Add subtract 9 to 5 which would be -4. So you should have 3x= -4 now
Step 3: Since you're "multiplying" 3 to x you're going to divide 3 to get Y by itself. So 3/3 cancels out and now you're left with y
Step 4: Divide 3 from -4 and you get -4/3
Let me know if you have any questions and I hope this helps :)
Mackenzie spent $20 at the local farmer’s market. She bought b pounds of blueberries that cost $4 per pound, and r pounds of raspberries that cost $6 per pound. She wrote the equation 4 b + 6 r = 20 to represent the cost of all the fruit. Which is equivalent to Mackenzie’s equation?
b = 5 minus three-halves r
b = 80 minus 240 r
r = StartFraction 10 Over 3 EndFraction + two-thirds b
r = 120 + 240 b
Answer:
the first option; b = 5 minus three-halves r
Step-by-step explanation:
4b+6r=20

Cody’s favorite snacks are pecans and almonds. At the Nut Haus, pecans sell for $2.00 a pound and almonds sell for $4.50 a pound. Cody wants to buy a mixture of nuts that weighs 6 pounds. He has $15.25 to spend on pecans and almonds.
Part A
Identify the two variables in the problem situation.
Part B
Write a system of two linear equations in two variables that could be used to determine the number of pounds of pecans and almonds Cody could purchase at the Nut Haus.
Answer:
Part A
The two variables are the amount of pounds that we dont know yet for the nuts and the almonds so we would have to put x for the amount of pounds for pecans and y for the amount of pound for nuts
Part B
2x + 4.50y = 15.25
Step-by-step explanation:
Step-by-step explanation:
x = pounds of pecans bought
y = pounds of almonds bought
x + y = 6
x×2 + y×4.5 = 15.25
x = -y + 6
(-y+6)×2 + y×4.5 = 15.25
-2y + 12 + 4.5y = 15.25
2.5y = 3.25
y = 3.25 / 2.5 = 3 1/4 / 2 1/2 = 13/4 / 5/2 = 13×2 / 4×5 =
= 26/20 = 13/10 = 1.3 pounds
x = -y + 6 = -1.3 + 6 = 4.7 pounds
Cody could buy 4.7 pounds of pecans and 1.3 pounds of almonds.

what is the slope?
what is the y-intercept?
proportional or not proportional?
Answer:
Slope(m)=3
Y-intercept= 0
y = 3x +0
Proportional
Step-by-step explanation:
m = -6--12/-2--4
m=6/2
m=3
-12 = 3(-4) + b
-12 = -12 + b
0=b
Answer:
slope, m = 3
y-intercept, b = 0
Proportional
Step-by-step explanation:
If we assume this is a straight line, we can calculate the slope between two of the given points. I'll pick (-2,-6) and 2,6).
Slope is the Rise (the change in y) over the Run (the corresponding change in x).
Rise for these two points: 6 - (-6) = 12
Run for the points is: 2-(-2) = 4
Rise/Run (Slope) = 12/3 = 4
The line becomes y=3x+b
b is the y-intercept. We can either solve for b by entering one of the points, but the y-intercept is the value of y when x=0. Behold: one of the points is (0,0), so we already have b. It is 0.
y=3x+0
y=3x is the equation.
slope, m = 3
y-intercept, b = 0
A non-proportional graph is a straight line that does not go through the origin. A proportional graph is one that does, so this is a proportional graph.

18= 1.57(multiply sign) X^2.2
please give me steps!!!
Answer: x = 3.030631 approximately
Explanation:
If you want to solve for x, then you could follow these steps:
[tex]18 = 1.57*x^{2.2}\\\\18/1.57 = x^{2.2}\\\\11.464968 \approx x^{2.2}\\\\x^{2.2} \approx 11.464968\\\\x \approx (11.464968)^{\frac{1}{2.2}}\\\\x \approx 3.030631\\\\[/tex]
In the second to last step, we have the value 11.464968 raised to the exponent of 1/(2.2) which is done to undo the exponent of 2.2 in the previous line. The rule used is [tex]a^b = c \to a = c^{1/b}[/tex]

Step-by-step explanation:
find the value of x and y
Answer:
x = 60
y = 30
Step-by-step explanation:
We know that all triangles' interior angles combined must have a sum of 180.
Since the triangle on the left is a equilateral triangle, we know that each angle is equal to 60.
Since we already know that the sum of the two angles in the top right is 90 (shown by the right angle symbol) and we know that the angle that isn't y is equal to 60, we must do the following step:
90 - 60 = y
90 - 60 = 30
y = 30
Now that we know the value of y, it's time to find the value of x.
We know that y = 30 and that the angle in the bottom right is equal to 90 (shown by right angle symbol).
Since all triangles' interior angles combined must have a sum of 180 and we already know that one angle is equal to 30 and the other is equal to 90, we must do the following:
180 - (90 + y) = x
180 - (90 + 30) = x
180 - 120 = x
180 - 120 = 60
x = 60
This gives us the answers y = 30 and x = 60

Tell whether x and y show direct variation x= (y-2)/(9)
PLEASE HELP I"LL MARK BRAINLIEST
EXPLAIN PLS
Answer:
not a direct variation
Step-by-step explanation:
x = (y-2)/9 is also x = y/9 - 2/9
we can convert this into slope-intercept form
y/9 = x + 2/9
y = 9x + 2
this equation is a straight line and is constantly going up BUT the y-intercept is not 0 so it is not a direct variation
the direct variation equation y = kx does not have a b or a y-intercept

and for 1 1/2 - sign should be there
b) first convert mixed fraction and add the terms in the parentheses
c) 9 7/11 - (5 + 1 1/2)
= (9*11 + 7) / 11 - ( 5 + (1*2 + 1)/2 )
= 106/11 - (5 + 3/2)
= 106/11 - (5*2 + 3)/2
= 106/11 - 13/2
= lcm of 2 and 11 is 22
= (106*2 - 13*11) / 22
= (212 - 143) / 22
= 69/22
= 66 + 3 / 22
= 3 3/22

FunctionFunctionNot a functionNot a function=================================================
Explanation:
Relation 1 is a function because any input item in the domain leads to exactly one and only one output item in the range. If we had say 2 arrows coming from "chair", and pointing to two different outputs, then we wouldn't have a function. It's perfectly possible to use words in place of numbers when talking about functions. All that matters is that we have one input map to exactly one output. Relation 2 is a function for similar reasoning as relation 1. It's possible to have an output repeated and still have a function. Relation 3 is not a function. Why not? Because of the points (j,v) and (j,t). The input j leads to more than output (v and t at the same time). A similar issue happens with the input 's' also.Relation 4 is also not a function. The repeated input this time is -5 which maps to the outputs z and 'a' at the same time.The conjugate of (2+i)²/3+i, in the form of a+ib, is
13/2 + i(25/2)
13/10 + i(-15/2)
13/10 +(-9/10)
13/10+(9/10)
Given that
(2+i)²/(3+i)
On multiplying both numerator and the denominator with (3-i) then
⇛ [(2+i)²/(3+i)]×[(3-i)/(3-i)]
⇛ [(2+i)²(3-i)]/[(3+i)(3-i)]
⇛ [(2+i)²(3-i)]/[(3²-i²)
⇛ [(2+i)²(3-i)]/(9-i²)
⇛ [(2+i)²(3-i)]/[9-(-1)]
Since ,i² = -1
⇛ [(2+i)²(3-i)]/(9+1)
⇛ [(2+i)²(3-i)]/10
⇛ [{2²+i²+2(2)(i)}(3-i)]/10
⇛ (4+i²+4i)(3-i)/10
⇛ (4-1+4i)(3-i)/10
⇛ (3+4i)(3-i)/10
⇛ (9-3i+12i-4i²)/10
⇛ (9+9i-4(-1))/10
Since, i² = -1
⇛(9+9i+4)/10
⇛(13+9i)/10
⇛ (13/10)+ i (9/10)
We know that
The conjugate of a+ib is a-ib
So,
The conjugate of (13/10)+ i (9/10) is
(13/10)-i(9/10) ⇛ (13/10)+i (-9/10)
Answer:-The conjugate of (13/10)+ i (9/10) is (13/10)+i (-9/10)
Additional comment:
The conjugate of a+ib is a-ib and i = -1(a+b)² = a²+2ab+b² • (a+b)(a-b)=a²-b² •(a-b)²=a²-2ab+b².Will give brainiest, need help
