Answer:

x = 50

Step-by-step explanation:

The two angles are vertical angles, so they are congruent. Congruent angles have equal measures. Set the angle measures equal to each other, and solve the equation for x.

2(x + 10) = 3x - 30

Distribute on the left side.

2x + 20 = 3x - 30

Subtract 2x from both sides.

20 = x - 30

Add 30 to both sides.

50 = x

x = 50

Solve the equation: \frac{2}{3}t=\frac{5}{9} (hint: reciprocal)

Aleks04 [339]

Given:

$\frac{2}{3}t=\frac{5}{9}$ $\text{ We know that the reciprocal of }\frac{2}{3}\text{ is }\frac{3}{2}\text{.}$

Multiply both sides by 3/2, we get

$\frac{3}{2}\times\frac{2}{3}t=\frac{3}{2}\times\frac{5}{9}$

Cancel out the common multiples, we get

$t=\frac{1}{2}\times\frac{5}{3}$

$t=\frac{1\times5}{2\times3}$

$t=\frac{5}{6}$

The solution of the given equation is

$t=\frac{5}{6}$

$t=0.8333.$

If f(x)=.5x+15 , what is the value of f(-4)

Levart [38]

Answer:

f(-4) = 13

Step-by-step explanation:

Hi there !

f(x) = 0.5x + 15

replace x = - 4

f(-4) = 0.5×(-4) + 15

= - 2 + 15

= 15 - 2

= 13
