8s + 9 = 7s + 6 <br>s= ?

denis-greek [22]

Answer:

s = -3

Step-by-step explanation:

8s + 9 = 7s + 6

Subtract 7s from each side

8s-7s + 9 = 7s-7s + 6

s+9 = 6

Subtract 9 from each side

s + 9-9 = 6-9

s = -3

A is in the shape of a quarter circle of a radius of 15cm. B is in the shape of a circle. the area of shape A is 9x the area of

RideAnS [48]

The radius of B is 2.5cm.

<h3>What is a circle?</h3>

A circle is the locus of points equidistant from a common point which is called the center of the circle.

Analysis:

Area of circle A = π $r^{2}$ /4 = π $(15)^{2}$ /4 = 225π/4

Area of circle B = π $r^{2}$

But A = 9B

225π/4 = 9 x π $r^{2}$

$r^{2}$ = 225/36 = 25/4

r = $\sqrt{\frac{25}{4} }$ = 5/2 = 2.5cm

3(0.7z+2.8)=7(1.5z+7.2)

AnnZ [28]

Answer:

z = -5

Step-by-step explanation:

3(0.7z + 2.8) = 7(1.5z + 7.2)

2.1z + 8.4 = 10.5z + 50.4

2.1z - 10.5z = 50.4 - 8.4

-8.4z = 42

z = 42/(-8.4)

z = -5
