Question

Need answer Asap please :) ​

Answer 1

Answer:

1. 11

2. -82

3. $\frac{8}{15}$

4. 36

5. 1

Step-by-step explanation:

1. 3x + 5, when x = 2

Plug in the value of x

3(2) + 5 = 6 + 5

= 11

2. 5xy + x - 4, when x = -3 and y = 5

Plug in the values

5(-3)(5) + (-3) - 4

-75 - 3 - 4 = -82

3. $\frac{6ab - c}{abc}$, when a = 5, b = 3, and c = 10

Plug in the values

$\frac{6(5)(3) - 10}{5*3*10}$

$\frac{90 - 10}{150}$

$\frac{80}{150}$

$\frac{8}{15}$

4. 3(xy + 6), when x = -6 and y = - 1

3(-6*-1 + 6)

3(6 + 6)

3(12)

36

5. $\frac{2x + 5}{3x - y}$, when x = -3 and y = -8

$\frac{2(-3) + 5}{3(-3) - (-8)}$

$\frac{-6 + 5}{-9 + 8}$

$\frac{-1}{-1} = 1$
