B.
When two lines intersect they form two pairs of opposite angles.
Vertical angles are always congruent, which means that they are equal.
so m<7 = m<8 or m<3y + 19 = m<5y-29

C. solve for y and measure <7 and <8

3y + 19 = 5y-29
5y - 3y = 19+29
2y = 48
y = 24

so
5y-29 = 5(24) - 29 = 91
3y + 19 = 3(24) + 19 = 91

so <7 = 180 - 91 = 89
<7 = <8 = 89

Billy has 2.4 m of ribbon for crafts. He wants to share it evenly with 12 friends. Billy has been making craft projects for seve

Triss [41]

Answer:

140 cm

Step-by-step explanation:

Given that:

Total length of ribbon present with Billy = 2.4 m

This ribbon is to be shared with 12 friends evenly.

Billy is doing this work of making craft for the past many years.

To find:

How many centimeters of ribbon that 7 friends will get?

Solution:

First of all, let us find out what length of ribbon will each person get.

Length of ribbon to be shared with each person = Total length of ribbon divided by total number of persons

Length of ribbon to be shared with each person = $\frac{2.4}{12} = 0.2\ m$

Now, The length of ribbon that 7 friends will get = 7 $\times$ 0.2 = 1.4 m

1 m = 100 cm

1.4 m = 1.4 $\times$ 100 cm = 140 cm

Which of the following is the solution set to the equation -4(x+1)^2 -3=- 51

ANTONII [103]

Answer:

x is equal to 2.5 and -4.5

Step-by-step explanation:

-4(x + 1)² - 3 = -51

-4(x² + 2x + 1) - 3 = -51

-4x² - 8x -3 - 3 = -51

-4x² - 8x - 6 = -51

-4x² - 8x = -45

-4(x^2 + 2x) = -45

-4(x^2 + 2x + 1) = -49

-4(x + 1)² = -49

(x + 1)² = 49/4

x + 1 = ± √(49/4)

x + 1 = ± 7/2

x = -1 ± 3.5

x = 2.5, -4.5
