What is the value of x? <br><br> A. 3cm <br> B. 4cm<br> C. 5cm<br> D. 4.5cm
Alexxx [7]

Answer:

5 cm

Step-by-step explanation:

32 / 4 = 8

40 / 8 = x

40 / 8 = 5

32 and 4 are corresponding, and 40 and x are as well. Find the relation between 32 and 4, then apply it to 40 to find the value of x.

Raj weighs a book and rounds the weights to the nearest tenth. Does this weight round to 1.5 pounds?
mel-nik [20]

Step 1: Locate and underline the tenth place (4) and look to the right (8)

1.48

Step 2: In this case, the digit to the right 8 is 5 or above. So, we add 1 to the tenth place 4. The digit at the right 8 becomes 0, thus we get 1.5 as the answer.

In short: 1.48 rounded to the nearest tenth is 1.5.

Hope that helped

Please help ONLY ONE QUESTION !!
xxTIMURxx [149]

Answer:

slope = - 4, y- intercept = 9

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 4x + 9 is in slope- intercept form

with slope m = - 4 and y- intercept c = 9

A proportional relationship has the form

y = mx

y = - 4x + 9 is not in this form

Hence the relationship is not proportional
