Step-by-step explanation:

9x - 2 = 5x + 54 because these angles are corresponding

9x - 5x = 54 + 2 add/subtract like terms

4x = 56 and this divided by 4

x = 14

9x - 2 + 10y + 6 = 180° because these two angles makes a straight line

9×14 - 2 + 10y + 6 = 180°

126 - 2 + 10y + 6 = 180° add like terms

130 + 10y = 180° subtract 130 from both sides

10y = 50 divide by 10

y = 10

Rectangle ABCD has vertices A(15, 18), B(−5, 3), C(1, −5), and D(21, 10).

erastova [34]

Answer:

1. 25

2. 10

3. 250

Step-by-step explanation:

Distance formula :√ (x2 - x1)² + (y2 - y1)² √ ()² + ()²

1. LENGTH OF AB :

A = 15,18

B = -5,3

√ (-5 - 15)² + (3 - 18)²

= √ 400 + 225

= 25

2. LENGTH OF AD :

A = 15,18

D = 21,10

√ (21 - 15)² + (10 - 18)²

= √36 + 64

= 10

AREA :

A=w x l

10 x25 = 250

The members of a basketball team need to raise $895 for new uniforms. They already have $351 from food sales. To raise the remai

Orlov [11]

Subtract what they already have from what they needed:

895 - 351 = 544

They need$544 more.

Divide how much more they need by the number of teams:

544/34 = 16

They need to charge each team $16
