Two cheaper books = x
more expensive = 1.5x
so, 2.5x=150
150/2.5=x=60
therefore the more expensive book = 90

1. 5 x 4 = A. 20

$\frac{2}{5} \times 25 = 2 \times 5 = 10$

the answer is D. 25

$\frac{3}{5} \div 15 = \frac{3}{5} \times \frac{1}{15} = \frac{1}{5} \times \frac{1}{5} = \frac{1}{25}$

the answer is A. 1/25

$4 \div \frac{1}{2} = 4 \times \frac{2}{1} = 8$

the answer is C. 8

$9 \div \frac{1}{3} = 9 \times \frac{3}{1} = 27$

the answer is D. 27

$20 \div \frac{1}{4} = 20 \times \frac{4}{1} = 80$

the answer is D. 80

$\frac{9}{10} \div \frac{1}{2} = \frac{9}{10} \times \frac{2}{1} = \frac{18}{10} = \frac{9}{5} = 1 \frac{4}{5}$

the answer is C. 1 4/5

$9 \div \frac{3}{2} = 9 \times \frac{2}{3} = \frac{18}{ 3} = 6$

the answer is B. 6

$\frac{3}{4} \div \frac{3}{8} = \frac{3}{4} \times \frac{8}{3} = 2$

the answer is A. 2

1. The point (3, 1) is on the line whose equation is 2x + y = c. What is the value of c?

Otrada [13]

Answer:

c = 7

Step-by-step explanation:

Given

2x + y = c

Since (3, 1) is on the line then it makes the equation true,

Substitute x = 3, y = 1 into the equation

2(3) + 1 = c

6 + 1 = c

7 = c

The Graph shows two lines A, and B

Allisa [31]

There is one solution for the pair of equations for lines A and B.

These two lines intersect, and will only intersect once. Both lines are going in opposite directions, so they will only continue to get farther and farther from each other. The only solution is the one place where these lines intersect.

Hope this helps!! :)
