Answer:
n+p=4.50
n=2p
2p+p=4.5
2p=4.5
p=$1.5
n=$3
Step-by-step explanation:
Answer:
Pencil: $1.50
Notebook: $3
Step-by-step explanation:
n = cost of notebook
p = cost of pencil
n + p = 4.5
n = 2p
substitute n into the first equation
2p + p = 4.5
3p = 4.5
p = 1.5
n = 2p
n = 2(1.5)
n = 3
2x-7=-3x+18
solve for x
Answer:
x=5
Step-by-step explanation:
2x−7=−3x+18
Step 1: Add 3x to both sides.
2x−7+3x=−3x+18+3x
5x−7=18
Step 2: Add 7 to both sides.
5x−7+7=18+7
5x=25
Step 3: Divide both sides by 5.
5x
5
=
25
5
x=5
Answer:
x = 5
Step-by-step explanation:
2x - 7 = -3x + 18
2x - 7 + 7 = -3x + 18 + 7
2x = -3x + 25
2x + 3x = -3x + 25 + 3x
5x = 25
x = 5
What is the solution to the system of equations? 4x + 2y = 1
5x = y - 18
Answer:
Step-by-step explanation:
X = -5/2
y = 11/2
Y= -2x + 1/2
Y= 5x + 18

Marcos buys 20 folders and 10 binders for a total of $100. Alicia buys 10 folders and 20 binders for $110. What is the price of each folder and each binder?
Answer:
folder is $3 binder is $4
Step-by-step explanation:
Let folder be x and binders be y
Marcos
20x+10y= 100----------1
Alicia
10x+20y= 110-------------2
solve 1 and 2
20x+10y= 100 X 1
10x+20y= 110 X 2
20x+10y= 100
-20x+40y= 220
-30y= -120
y= 120/30
y= 4
put y= 4 in 1
20x+10y= 100
20x+10(4)= 100
20x+40=100
20x=100-40
20x=60
x= 60/20
x=3

Answer: Yes, they are similar- and the Scale Factor is 2.5
Step-by-step explanation: To find the scale factor, simply divide the larger number on the bigger shape by its counterpart in the smaller image, so for example: 60 divided by 24 is 2.5, and there is your scale factor. You can further test this by multiplying 4 x 2.5 which gives us 10, the other value on the larger shape.
Company A charges $125 annual fee plus $5 per hour car share fee.
Company B charges $80 plus $10 per hour. What is the minimum number of
hours that a car share needs to be used per year to make company A a better
deal?
Answer:
Greater than 9 hours.
Step-by-step explanation:
Company A annual fees = $125
Company A share fee = $5 per hour
Let number of hour be x, then
Company A total fee = $125 + 5x
Similarly, Company B annual fees = $80
Company B share fee = $10 per hour
Let number of hour be x, then
Company B total fee = $80 + 10x
If company A is a better deal, then
125 + 5x < 80 + 10x
= 125 - 80 < 10x - 5x
= 45 < 5x
= x > 45÷ 5
= x > 9
So, number of hours must be greater than 9 hours.

Answer:
y = 4.375x + 2.5
Step-by-step explanation:
The equation of the line is expressed as y = mx+c
m is the slope
c is the intercept
Using the coordinate points (0, 2.5), (4, 20)
Slope m = 20-2.5/4-0
m = 17.5/4
m = 4.375
Get the intercept
Substitute (0, 2.5) and m = 4.375 into y - mx+c
2.5 = 4.375(0) + c
2.5 = c
Get the equation required
y = 4.375x + 2.5

Answer:
[tex]7xy^{2} \sqrt[3]{2xy}[/tex]
Step-by-step explanation:
[tex]\sqrt[3]{686x^{4} y^{7}}[/tex]
[tex]686 = 343 * 2[/tex]
[tex]x^{4} = x^{3} * x[/tex]
[tex]y^{7} = y^{3} * y^{3} * y[/tex]
[tex]\sqrt[3]{343} =7[/tex]
[tex]\sqrt[3]{x^{3}} = x[/tex]
[tex]\sqrt[3]{y^{3}* y^{3}}[/tex] = [tex]y^{2}[/tex]
so you're left with 2, x, and y inside the cube root, and 7, x, and y^2 outside
[tex]7xy^{2} \sqrt[3]{2xy}[/tex]

j = Jana's age B
s = sister's age e
Enter an equation:
+
Answer:
Definitions of the variables in the situation:
J = Jana's age
S = Sister's age
The Equation:
J + 8 = S
Step-by-step explanation:
Explanation:
In the equation we will use the variable J for Jana and S for Janna's sister. Since we know Jana's age plus 8 equals her sister's age, the equation will be J + 8 = S

0.4(3.21x+5.6)
Answer:
1.284x + 2.24 is the answer.
Step-by-step explanation:
Simply, all we have to do is distribute the 0.4 to the 3.21x and the 5.6.
(0.4 × 3.21x) + (0.4 × 5.6)
= 1.284x + 2.24
#teamtrees #WAP (Water And Plant)
Answer: = 1.284x + 2.24
explanation: This question is easily solved through the process of distribution.
(0.4 × 3.21x) + (0.4 × 5.6) = 1.284x + 2.24
Sorry for the late answer hope this helped!
