Answer:

x = 36

Step-by-step explanation:

the angles shown are supplementary

supplementary angles add up to 180°

This means 2x + 3x = 180

2x + 3x = 180

combine like terms

5x = 180

divide both sides by 5

x = 36

Let F(x)=-7x-12 and g(x)=13-3x. What is f-g?
Oxana [17]

Answer:

(f - g)x = -4x - 25

Step-by-step explanation:

Given:

f(x) = -7x - 12

g(x) = 13 - 3x

Required:

(f - g)x

SOLUTION:

(f - g)x = f(x) - g(x)

f(x) - g(x) = (-7x - 12) - (13 - 3x)

= -7x - 12 - 13 + 3x

Collect like terms

= -7x + 3x - 12 - 13

(f - g)x = -4x - 25

The museum's show for July features 30 oil paintings by different artists. All artists show the same number of paintings and eac
boyakko [2]
Answer: We have many options:
1) 15 artists, with 2 paintings per artist.
2) 10 artists, with 3 paintings per artist.
3) 6 artists, with 5 paintings per artist.
4) 5 artists, with 6 paintings per artist.
5) 3 artists, with 10 paintings per artist.
6) 2 artists, with 15 paintings per artist.

by different artists, then the number of artists must be more than 1.
each artist shows more than 1 painting: >1 painting/artist

(30 oil paintings)/(2 paintings/artist)=15 artists
(30 oil paintings)/(3 paintings/artist)=10 artists
(30 oil paintings)/(5 paintings/artist)=6 artists
(30 oil paintings)/(6 paintings/artist)=5 artists
(30 oil paintings)/(10 paintings/artist)=3 artists
(30 oil paintings)/(15 paintings/artist)=2 artists

Original price? The discount is 40% in the sale price is $18
dimulka [17.4K]
The original price is 30$ because we know that the new price is worth 60% of the old price. We can set up an equation to model this: 0.60x = 18. Dividing both side by 0.60 gives us an original value of 30. If you take 40% off of 30 you get 18 — allowing us to check our work.

Which expression is equivalent to the given expression?
Aneli [31]

Answer:

-\frac{1}{4}(1 + 2y )

Step-by-step explanation:

Given

-(\frac{1}{2}y + \frac{1}{4})

Required

Select equivalent expression

Write each term as a product of 1/4

-(2 * \frac{1}{4}y + 1 * \frac{1}{4})

Factorize:

-\frac{1}{4}(2 * y + 1 * 1)

-\frac{1}{4}(2y + 1)

Apply commutative property:

-\frac{1}{4}(1 + 2y )

<em>Hence, option (a) is correct.</em>
