Answer:
1a: x+3 = 5
1c: 6 = 2z
2b: x = 2
2d: 3 = z
3: the solutions make the hangars balance
Step-by-step explanation:
1. We can write the equations by listing the contents of the hangar and using an equal sign to show the balance between left side and right side. It can work well to put left side contents of the hangar on the left side of the equal sign.
A: x + 3 = 5
C: 1 + 1 + 1 + 1 + 1 + 1 = z + z simplifies to 6 = 2z
__
2. B: We can subtract 3 from both sides of the hangar (and equation) to find the value of x.
(x +3) -3 = 5 -3
x = 2 . . . . . hangar balances with 2 on the right
D: We can divide both sides of the hangar by 2, splitting the content into two equal parts. Then one of those parts can be removed from each side.
2(3) = 2(z)
3 = z . . . . . . hangar balances with 3 on the left
__
3. The found values will keep the hangar in balance when they are substituted for the corresponding variables.
A: 2 + 3 = 5
C: 1 + 1 + 1 + 1 + 1 + 1 = 3 + 3

The result of multiplying a number by 3 and subtracting 5 is the
same as doubling the number and adding 9. What is the number?
Answers
Answer:
n = 14
Step-by-step explanation:
let 'n' = the number
3n - 5 = 2n + 9
n - 5 = 9
n = 14
Answer:
14
Step-by-step explanation:
We have to replace the unknown quantity with "x" and work with it.
The result of multiplying a number by 3 and substracting 5
3x - 5
Is the same as
3x-5= (__)
Doubling the number and adding 9
3x- 5= 2x+9
Then we solve it like any equation
3x - 5 = 2x + 9
3x - 2x = 9 + 5
x = 14

Answer:
5.5
Step-by-step explanation:
57-29.5 / 10-5 = 5.5
Answer:
5.5
Step-by-step explanation:
The rate of change of a relationship is the ratio of corresponding changes in value. Symbolically, we indicate a change with the greek letter Δ (pronounced "delta"). A change in x is written Δx ("delta eks") and a change in y is written Δy ("delta why"). We're looking for the ratio Δy/Δx ("delta y over delta eks").
Mathematically, Δx and Δy are the differences between two corresponding x an y values. To pick these, we can take any two rows in our table. Let's pick rows 4 and 2, nice whole numbers:
[tex]\Delta{x}=20-10=10\\\Delta{y}=112-57=55\\\Delta{y}/\Delta{x}=55/10=11/2=5.5[/tex]
We can confirm that this holds for every other pair, too - picking rows 2 and 1 as an example:
[tex]\Delta{x}=10-5=5\\\Delta{y}=57-29.5=27.5\\\Delta{y}/\Delta{x}=27.5/5=275/50=11/2=5.5[/tex]

3 pounds to 24 ounces write each ratio in simplest form
Answers
Answer:
2:1
Step-by-step explanation:
First we convert 3 pounds into ounces which is 3x16 because 1 pound=16 ounces. So 48 ounces=3 pounds. So know we have the ratio 48:24 which we can simplify to 2:1
Hope this helps :)
The required simplest ratio for 3 pounds to 24 ounces is 1 : 8.
Given that,
3 pounds to 24 ounces write each ratio in simplest form is to be determined.
The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
The process in mathematics to operate and interpret the function to make the function simple or more understandable is called simplifying and the process is called simplification.
Here,
The ratio of 3 pounds to 24 ounces,
Simplest form = 3 / 24 = 1 / 8.
Thus, the required simplest ratio for 3 pounds to 24 ounces is 1 : 8.

\displaystyle \frac{\sin^2(x)-\sin(x)-2}{\sin(x)-2}
sin(x)−2
sin
2
(x)−sin(x)−2
To make it simpler and more clear, we can let u = sin(x). So:
\displaystyle \frac{u^2-u-2}{u-2}
u−2
u
2
−u−2
Now, it becomes obvious that we can factor, which produces:
\displaystyle =\frac{(u-2)(u+1)}{u-2}=
u−2
(u−2)(u+1)
Cancel:
=u+1=u+1
And substituting back:
=\sin(x)+1=sin(x)+1
Hence, our answer is A.

Answer:
a = 14.9
b = 11.1
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relevant relationships.
Sin = Opposite/Hypotenuse
Cos = Adjacent/Hypotenuse
In this triangle, that means ...
sin(48°) = b/a
cos(48°) = 10/a
Using the cosine relation, we can find 'a':
a = 10/cos(48°) ≈ 14.9
Then using the sine relation, we have ...
b = a·sin(48°) ≈ 11.1
_____
Additional comment
When computing 'b', the full precision value of 'a' should be used.

ive just joined into a class from remote to now hybrid. we are doing how to find out if an ordered pair is a solution to the linear equation. i am so lost. please help.
Answers
Answer:
Step-by-step explanation:
You'll be given an equation that contains an x and a y.
You'll also be given an ordered pair. Plug the ordered pair into the equation and see if the equation is true.
For example:
Is (0,4) a solution to the equation 2x+3y = 15 ?
Plug the coordinates of (0,4) into the equation:
2·0 + 3·4 = 15
This simplifies to 12 = 15, which is obviously false, so (0,4) is not a solution to the equation.
