Question 7 (1 point)

Mathematics

1 answer:

True [87]2 years ago

3 0

Step-by-step explanation:

since they are similar, the same scale factor must apply to every side.

so, it is sufficient to look on only one pair of corresponding sides.

16 × x = 40

x = 40/16 = 10/4 = 5/2 = 2.5

so, the scaling factor from the small to the large shape is 2.5 or 5/2.

it seems it is your choice which format of the 2 to use.

This is hard for me, can someone show me how, Find m∠UTS, if m∠UTV=x+15, m∠VTS=140∘, and m∠UTS=15x+15.

Assoli18 [71]

Answer:

165

Step-by-step explanation:

First, m<UTS=m<UTV+m<VTS by Angle Addition Postulate. Then, you substitute all the values that you provided for the angles. 15x+15=x+15+140. You then solve for x.

15x+15=x+155

14x=140

x=10

You then plug back in 10 for X in the value of m<UTS. 15(10)+15=165

2/3 x + 5/6 = x - 1/2 SHOW WORK PLEASE

Digiron [165]

Answer:

x=4

Step-by-step explanation:

2/3 x + 5/6 = x - 1/2

Multiply each side by 6 to clear the fractions

6(2/3 x + 5/6) = 6(x - 1/2)

Distribute

4x +5 = 6x-3

Subtract 4x from each side

4x+5 -4x = 6x-3-4x

5 = 2x-3

Add 3 to each side

5+3= 2x-3+3

8 =2x

Divide by 2

8/2 =2x/2

4 =x

1. What is the value of the y-coordinate of the solution to the system of equations x + 2y = 9 and x - y = 3? 1) 6 3) 3 2) 2 4)

Andreyy89

Answer:

2) 2

Step-by-step explanation:

Subtract each equation from each other

x + 2y = 9

-x+ y = -3

3y = 6

3 3

So y = 2
