<h3><u>The value of x is equal to 8.</u></h3>
3(x + 1) = 19 + x
<em><u>Distributive property.</u></em>
3x + 3 = 19 + x
<em><u>Subtract x from both sides.</u></em>
2x + 3 = 19
<em><u>Subtract 3 from both sides.</u></em>
2x = 16
<em><u>Divide both sides by 2.</u></em>
x = 8
Answer:
solution given:
B.
CE=2×2=4[base side is double to the line of mid point]
AB=15/2=7.5[b is a mid point]
m<AEC=75°[ corresponding angle]
5.
given:
BD=x+1
CE=x+10
we have
2BD=CE
2(x+1)=x+10
2x+2=x+10
2x-x=10-2
x=8
You can solve this with next proportion =>
3 : 5 = 4 : x => 3x= 5*4 => 3x = 20 => x=20/3 = 6 (2/3)
The correct answer is x= 6 (2/3)
Good luck!!!
7/10x - 5 = 1/2x
7/10x - 1/2x = 5
7/10x - 5/10x = 5
2/10x = 5
x = 5 / (2/10)
x = 5 * 10/2
x = 50/2
x = 25 gallons <===
