8 0

So,

$\frac{p}{4} + 8 = 7$

Subtract 8 from both sides
$\frac{p}{4} = -1$

Multiply both sides by 4
p = -4

Solve the equation 4 sin (x +30°) = 2 for 0 < x < 365

tatuchka [14]

$4 \sin(x + 30) = 2 \\ \sin(x + 30 ) = \frac{2}{4} \\ \sin(x + 30) = \frac{1}{2} \\ \sin(x + 30) = \sin(30) \\ x + 30 = 30 \\ x = 30 - 30 \\ x = 0$

Hence, x = 0°, 180° and 360° Ans

Solve for 9(p-4)=-18

statuscvo [17]

9(p - 4) = -18

Simplify our equation by multiplying the parenthesis out.

(9 × p) + (9 × -4) = -18

Simplify.

9p + (-36) = -18

Get rid of parenthesis.

9p - 36 = -18

Now, since we're trying to isolate "p," we need to add 36 to both sides.

9p - 36 + 36 = -18 + 36

Simplify.

9p = 18

Divide both sides by 9.

9p ÷ 9 = 18 ÷ 9

Simplify.

p = 2

~Hope I helped! :)~

– (9 – 5c) + 18 – c = 37 please show your work.

love history [14]

-9 + 5c + 18 - c = 37

4c + 9 = 37
4c = 37 - 9

4c = 28

4c/4 = 28/4

c = 7

hope this helps
