Answer:
Wheres is the figure?
Step-by-step explanation:
<span>2a(5-b)=3b+7
<em>[open bracket]</em>
10a - 2ab = 3b + 7
<em>[solve for b, so we need to move all terms with b to the left]</em>
<em>[-3b on both sides]</em>
10a - 2ab - 3b = 3b + 7 - 3b
10a - 2ab - 3b = 7
<em>[move all those without b to the right]</em>
<em>[-10a on both side]</em>
10a - 2ab- 3b - 10a = 7 - 10a
-2ab - 3b = 7 - 10a
<em>[divide by -1 through to change b to be positive]</em>
2ab + 3b = 10a - 7
<em>[take b out as the common factor]</em>
</span>b(2a + 3) = 10a - 7<span>
<em>[divide by (2a+3) through]</em>
b = (10a -7)/(2a+3)

Answer: Oc. 28
Step-by-step explanation:
5^2=25
3+5^2=3+25=28
Answer:
x=2,y=0
(You did not provide enough information for me to know what to do with said equations, so I'm assuming it was System of Equations.)
Answer:
15 square feet
Step-by-step explanation:
Multiply 1.5 by 3 which equals 4.5
Multiply 1.5 by 2 which equals 3
Add the above answers (4.5 plus 3)
Then multiply by 2 (7.5 times 2)
It equals 15
I hope this helps and that this is the right problem. There is no picture shown but I just did this problem for someone else so I thought I would take a shot at it :)
