Answer:
5/2 Hope this helped
Step-by-step explanation:
Answer: H=12 and B=8
Looking at the problem, you are given the area, <em>a</em> , and told the h is 4 meters longer than <em>b; </em>in other words, <em>h</em>=<em>b</em>+4.
Since <em>a=</em>1/2<em>bh</em>, you can replace <em>a</em> with 48. Also, since <em>h</em> is <em>b</em>+4, you can replace that as well. You'd end up with this equation:
48=1/2b(b+4)
1. Seeing that 48 is 1/2 of <em>b,</em> you know that you have twice the value of 48, or 96. So, you can put that 96=<em>b(b+4). </em>
2.<em> </em>Now, thinking through factors of 96- 1 x 96, 2 x 48, 3 x 32, 4 x 24, 6 x 16, or 8 x 12, the only pair in which <em>h </em>is b+4 is 12 x 8.

Answer:
x = 12
Step-by-step explanation:
39/26 = 1.5
18/x = 1.5
18 = 1.5x
18/1.5 = x
12 = x
First, you need to use the distributive property and distribute the 2 inside the parentheses.
2(x + 1) + 3x = 17
2(x) + 2(1) + 3x = 17
2x + 2 + 3x = 17 -Combine like terms
2x + 3x + 2 = 17
5x + 2 = 17 -Subtract 2 from both sides of the equation.
5x + 2 - 2 = 17 - 2
5x = 15 -Finally, divide each side by 5 to find your answer
5x/5 = 15/5
x = 3
Hope this helps you!
