Solve for x in the figure below
fredd [130]

Answer:

x = 35.4

Step-by-step explanation:

Sum of all interior angles in a triangle = 180°

Therefore:

(x + 2)° + (2x + 2)° + (2x - 1)° = 180°

x + 2 + 2x + 2 + 2x - 1 = 180

Collect like terms

x + 2x + 2x + 2 + 2 - 1 = 180

5x + 3 = 180

Subtract 3 from each side

5x + 3 - 3 = 180 - 3

5x = 177

Divide both sides by 5

5x/5 = 177/5

x = 35.4

SOS if anyone could help that would be appreciated!!!❤️
Anastaziya [24]

Answer:

See below

Step-by-step explanation:

2e)15-4x=10x+45

Solve:

15-4x=10x+45\\-4x-10x=45-15\\-14x=30\\ \boxed {x=-\dfrac{15}{7}}3(x+1)=21

Check:

15-4 \left(-\dfrac{15}{7} \right)=10\left(-\dfrac{15}{7} \right)+45

15+\dfrac{60}{7} \right)=-\dfrac{150}{7} +45

\dfrac{210}{7}  =30

30=30

3a) 3(x+1)=21

Solve:

3(x+1)=21\\3x+3=21\\3x=18\\x=6

3b) 2+3(x+1)=6x

2+3x+3=6x\\5=3x\\

x=\dfrac{5}{3}

3c) -2(2x-3)=-2

Solve:

-2(2x-3)=-2\\-4x+6=-2\\-4x=-8\\x=2
