If 3x plus 2 equals 90 then what is the value of x

Firdavs [7]

Hello!

$3x+2=90$

Explanation:

↓↓↓↓↓↓↓↓↓↓↓↓↓

First you had to subtract by 2 from both sides of the equation.

$3x+2-2=90-2$

Simplify

$3x=88$

Then you divide by 3 from both sides of the equation.

$\frac{3x}{3}=\frac{88}{3}$

Simplify it should be the correct answer.

$x=\frac{88}{3}$

Answer⇒⇒⇒⇒⇒x=88/3

Hope this helps!

Amayo943,

Remember that with exponents you have to multiply the number of exponets by the same number it's in for example: $1^2 = 1 \times 1$ In this case you need to know that:

$15^2 = 15 \times 15$
$15 \times 15 = 225$
$=225$

Therefore your answer is "225."

Hope this helps!

Why does a rectangle with different side lengths have only 2 lines of symmetry?

ICE Princess25 [194]

Answer:

C. all four angles are congruent, and opposite sides are congruent for a horizontal and vertical line of reflection

Step-by-step explanation:

A. isn't correct because all four sides aren't congruent, only the pair of opposite sides are congruent. Sense only opposite side are congruent you can only reflect the opposite sides onto each other and not diagonally meaning B. and D. are incorrect leaving C. all four angles are congruent, and opposite sides are congruent for a horizontal and vertical line of reflection as the correct answer
