1. 5(2x + 1) = 35<br> I need help what’s the answer showed work

Airida [17]

Answer:

x=3

Step-by-step explanation:

5(2x+1)=35

Step 1: Simplify both sides of the equation.

5(2x+1)=35

(5)(2x)+(5)(1)=35(Distribute)

10x+5=35

Step 2: Subtract 5 from both sides.

10x+5−5=35−5

10x=30

Step 3: Divide both sides by 10.

x=3

nikklg [1K]

Answer:

The correct option is B.

Step-by-step explanation:

It is given that there is a strong, negative, linear relationship between x and y. where, x is the number of consecutive hours a worker has been assembling chainsaws and y is the number of chainsaws he can produce in an hour.

He finds that 70%of the variation in chainsaws produced per hour can be explained by the regression of y on x.

$y=-\frac{70}{100}x$

$y=-0.7x$

The slope is -0.7, therefore option B is correct.
