need this before june 8th ill give 100 pts THIS IS URGENT SOMEONE PLEASE ANSWER THESE 5 QUESTIONS I NEED THEM EITHER TODAY OR TOMMOROW (BEFORE JUNE 8th or 9th)

Answer 1

Explanation:

#15) If the circles are identical then the diameters and radii are the same respectively

r = 4x > for circle 1

d = 2x +12 >diameter for 2nd circle. Change to radius by dividing by 2

r = (2x+12)/2

r = x + 6 >for circle 2

Make the r's equal

x+6 = 4x

6 = 3x

x = 2

#14) They want answer in C so just go from Kelvin to Celsius. Skip going to Farenheit.

K = C +273.15

3.5 = C +273.15

C = -269.65

#13)

1/7 A= 3

A = 21

1/8 B = 2

B= 16

no number)

10x + 5 + 5x - 1 = ____(2x + ____)

16x + 4

8 (2x +1/2)

Blank1: 8 Blank2: 1/2

#10)

2x +3x+4x =180

9x = 180

x= 20

2x = 40

3x = 60

4x = 80
