Answer: ∠ABE and ∠CBD

∠ABC and ∠EBD

Step-by-step explanation:

The vertical angles are the pair of the opposite angles that are formed when two lines crosses each other .

They are also known as vertically opposite angles.

In the given picture , it can be seen that two lines AD and ECare intersecting each other at vertex B.

Then, the pair of angles are vertical angles are :

Answer:

Each shirt cost $7 and each pair of shorts cost $17 .

Step-by-step explanation:

let shirts be represented as x

let shorts be represented as y

Younger brother spent $79 on 4 new shirts and 3 pairs of shorts.

4 x + 3 y = $79 .......equation 1

Older brother purchased 7 new shirts and 8 pairs of shorts and paid a total of $185.

7 x + 8 y = $185 .......equation 2

multiply equation 1 by 7 and equation 2 by -4 and add both equations to get the value of y.

7 × (4 x + 3 y = $79) ⇒ +28 x + 21 y = $553

-4 × (7 x + 8 y = $185) ⇒ -28 x - 32 y = - $740

0 - 11 y = - $187 ⇒ -11 y = - $187

y = $\frac{- $187}{- 11}$ ⇒ y = $17

shorts = y = $17

put value of y in equation 1

4 x + 3 ( $17 ) = $79 ⇒ 4x + $51 = $79 ⇒ 4x = $79 - $51

4x = $28 ⇒ x = $\frac{$28}{4}$ ⇒ x = $7

Shirts = x = $7

The sides of a rectangle are in the ratio of 4:5. If the width is 28 in., find the length, the perimeter, and the area of this r

nadezda [96]

If the width is 28 inches, then divide that by 4 and you get 7. You multiply that by 5 to get the length. That would be 35. Just to check, you know that the width 28 and length 35 are in ratio 4:5 if you divide by 7. The perimeter would be 2(35+28)=63*2=126. So the perimeter is 126. The area would be 35*28 which is 980. To sum up, the answers are as follows.

Length: 35 in
Perimeter: 126 in
Area: 980 inches squared.

If a =-2 and b= 2 what will be the value of a^b

raketka [301]

Write out the equation;

y=a^b
y=(-2)^2
y=(-2)(-2)
y=4

Therefore, the value of a^b is 4

Hope I helped :)
