Answer:

1. 4

2. 6

3. 11

Step-by-step explanation:

Plug each number into the equation (in place of x) to get the answer.

1. f(-2) = -2+6 = 4

2. f(0) = 0+6 = 6

3. f(5) = 5+6 = 11

$\huge\text{Hey there!}$

$\mathsf{\dfrac{2}{5}x-7=11}$

$\large\textsf{ADD 7 to BOTH SIDES}$

$\mathsf{\dfrac{2}{5}x -7+7=11+7}$

$\large\textsf{CANCEL out: -7 + 7 because that gives you 0}$

$\large\textsf{KEEP: 11 + 7 because it helps you solve for your x-value}$

$\mathsf{11 + 7 = 18}$

$\large\text{New EQUATION: }\mathsf{\dfrac{2}{5}x = 18}$

$\large\textsf{MULTIPLY }\mathsf{\dfrac{5}{2}}\large\textsf{ to BOTH SIDES }$

$\mathsf{\dfrac{2}{5}x \times \dfrac{5}{2}=\dfrac{5}{2}\times18}$

$\large\textsf{CANCEL out: }\mathsf{\dfrac{5}{2}\times\dfrac{2}{5}}\large\textsf{ because it gives you 1}$

$\large\textsf{KEEP: }\mathsf{\dfrac{5}{2}\times 18}\large\textsf{ because it solves for x}$

$\large\textsf{New EQUATION: }\mathsf{x =18\times\dfrac{5}{2}}$

$\mathsf{18\times\dfrac{5}{2}=x}$

$\mathsf{18\times\dfrac{5}{2}=\bf 45}$

$\boxed{\boxed{\large\textsf{Answer: \huge \bf Option J. 45}}}\huge\checkmark$

John got a 76, 68, and 83 on his first three test. What score does he need on his fourth test to achieve an 80 average?

shepuryov [24]

It's 93.
simple calculate it by:
(76+68+83+x)/4=80
then 73*5-(67+75+73+69)=x
where x here is the grade needed to reach an av. of 80. 4 is the number of tests.
