Step-by-step explanation:
[tex]3x-y=12\\ =>3x = 12+y\\=>x=\frac{y+12}{3}[/tex]
Putting the value of x in [tex]\frac{8^{x} }{2^{y} }[/tex] gives :-
[tex]\frac{8^\frac{y+12}{3} }{2^y} = \frac{2^3(\frac{y+12}{3} )}{2^y} = \frac{2^{y+12} }{2^y} = 2^{y+12-y}=2^{12}[/tex]

(5x+2) = 32 what is the value of x ?
Answer:
x=6
Step-by-step explanation:
5x+2=32
Step 1: Subtract 2 from both sides.
5x+2−2=32−2
5x=30
Step 2: Divide both sides by 5.

The base of a triangular prism is a right triangle with a base of 5 inches and a height of 12 inches. The height of the prism is 21 inches. Whats volume of the prism?
Answer:
630 cubic inches of 630 in³
Step-by-step explanation:
The formula for the volume of a triangular prism = (Area of the base) × Height of the triangular prism
Area of the base = 1/2 × base × height
= 1/2 × 5 inches × 12 inches
= 30 square inches
Volume of the Triangular prism = Area of the base × Height of the Triangular Prism =
Height of the triangular prism = 21 inches
Volume of the Triangular Prism = 30 Square inches × 21 inches
= 630 cubic inches of 630 in³

Sydni has 2 fractions and she is confused about how to find a common denominator. The fractions are 2/3 and 3/5. Explain how you would tell Sydni how to determine the least common denominator.
Answer:
By finding the least common multiples of the denominators of the two fractions
Which is 15
Step-by-step explanation:
Fraction A = 2/3
Fraction B = 3/5
To find the least common denominator of the two fractions,
Fraction A = 2/3 and Fraction B = 3/5, Sydni will have to find the least common multiples of denominator 3 and denominator 5.
Multiples of denominator 3 = 6, 9, 12, 15, 18, 21
Multiples of denominator 5 = 10, 15, 20, 25
The least common multiples of the two denominators is 15
Therefore, the common denominator of Fraction A = 2/3 and Fraction B = 3/5 is 15
Jim was given three functions and asked to determine ƒ + (g ○ h). The functions were ƒ (x) = x2, g(x) = 3x + 1, and h(x) = 2x. Jim started by writing the problem as (ƒ + (g ○ h))(x) = x2 + 2(3x + 1). What was Jim's mistake? What is the correct solution? A. Jim omitted the x in h(x); (ƒ + (g ○ h)) = 7x2 + 2x. B. Jim should have added ƒ and g first; (ƒ + (g ○ h)) = 4x2 + 6x + 1. C. Jim incorrectly performed h ○ g instead of g ○ h; (ƒ + (g ○ h)) = x2 + 6x + 1. D. Jim did not follow the order of operations; (ƒ + (g ○ h)) = x2 + 6x + 2.

Answer:
4g + 36
Step-by-step explanation:
Distribute the 4 to the parentheses:
4(g) = 4g
4(9) = 36
Add the terms together:
4g + 36 is the distributed expression
Larry McCoy desposited three checks to his checking account he remembers that one of the checks was twice the amount of the smallest checks and the largest checks was equal in amount of the sum of the other two if Larry revived 50 cash in cash and had a total deposit of 355,what was the amount of each of three checks?plesae it’s urgent ?
$67.50
Step-by-step explanation:
The amount of each of three checks is 67.5, 135 and 202.5 respectively
Given:
let
amount of smallest check = c
Amount of larger check = 2 × c
= 2c
Amount of largest check = (c + 2c)
= 3c
Amount revived = 50
Total deposit = 355
Total amount in the account = amount of smallest check + Amount of larger check + Amount of largest check
50 + 355 = c + 2c + 3x
405 = 6c
c = 405 ÷ 6
c = 67.5
Therefore,
amount of smallest check = c
= 67.5
Amount of larger check = 2 × c
= 2c
= 2(67.5)
= 135
Amount of largest check = (c + 2c)
= 3c
= 3(67.5)
= 202.5

Tina made $121 this week for workkng 22 hours. How much will she make next week if she gets paid at the same rate but only works 14 hours?
Answer: she made 77 dollars
Step-by-step explanation:
121 divided by 22 is 5.5
5.5 will be her pay rate per hour
5.5 times 14 is 77
Answer:
77 dollars
Step-by-step explanation:
We can use ratios to solve
121 dollars x dollars
--------------- = --------------------
22 hours 14 hours
Using cross products
121 * 14 = 22x
Divide each side by 22
121 * 14/22 = x
77 =x
∠A and ∠B are vertical angles. If m∠A=(3x-30)° and m∠B=(2x-9)°,then find the value of x.
Answer:
x = 21
Step-by-step explanation:
Vertical angles are congruent, thus
∠ A = ∠ B , substitute values
3x - 30 = 2x - 9 ( subtract 2x from both sides )
x - 30 = - 9 ( add 30 to both sides )
x = 21
Hello there! :)
[tex]\huge\boxed{x = 21}[/tex]
Vertical angles are congruent, therefore:
∠A ≅ ∠B
3x - 30 = 2x - 9
Subtract 2x from both sides:
3x - 2x - 30 = 2x - 2x - 9
x - 30 = -9
Add 30 to both sides:
x - 30 + 30 = -9 + 30
x = 21.
