Please solve the equation (15m + 3)/2 = -6
stiv31 [10]

Answer:

m = - 1

Step-by-step explanation:

Given

\frac{15m+3}{2} = - 6

Multiply both sides by 2 to clear the fraction

15m + 3 = - 12 ( subtract 3 from both sides )

15m = - 15 ( divide both sides by 15 )

m = - 1

The measure of one angle is thirteen less than five times the measure of another angle. The sum of the measures of the two angle
Oduvanchick [21]

Answer:

The two angles are 25.5 and 114.5

Step-by-step explanation:

<u><em>x = measure of one angle </em></u>

<u><em>5x - 13 = measure of the other angle {one angle is 13 less than 5 times the other} </em></u>

<u><em> x + 5x - 13 = 140 {sum of the two angles is 140} </em></u>

<u><em>6x - 13 = 140 {combined like terms} </em></u>

<u><em> 6x = 153 {added 13 to each side} </em></u>

<u><em>x = 25.5 {divided each side by 6} </em></u>

<u><em>5x - 13 = 114.5 {substituted 25.5, in for x, into 5x - 13}</em></u>

X squared plus 8 squared equals 9<br> What is X?
BabaBlast [244]

Answer:

x = i\sqrt{55} , -i\sqrt{55}

Step-by-step explanation:

x^2 + 8^2 = 9

Simplify the 8^2

x^2 + 64 = 9

Subtract 64 from both sides

x^2 = -55

Take the square root from both sides

x = +/- \sqrt{-55}

Simplify

x = i\sqrt{55} , -i\sqrt{55}

Hope this helps!
