Answer:
x = 4
CB = 28
Step-by-step explanation:
In triangle ABC,
AB = CB..... (given)
Therefore,
7x = 5x + 8
7x - 5x = 8
2x = 8
x = 8/2
x = 4
CB = 5x + 8 = 5*4 + 8 = 20 + 8 = 28
Answer:
see below
Step-by-step explanation:
4(5n-7)+10n+2
Distribute
20n -28 +10n+2
Combine like terms
30n-26
Assuming you meant =
4(5n-7)=10n+2
Distribute
20n -28 =10n+2
Subtract 10n from each side
20n-10n-28 = 10n-10n+2
10n-28 =2
Add 28 to each side
10n-28+28=28+2
10n=30
Divide by 10
10n/10 =30/10
n=3
9(x+3)=4x-3
Distribute
9x+27 = 4x-3
Subtract 4x from each side
9x-4x+27 = 4x-4x-3
5x +27 =-3
Subtract 27 from each side
5x+27-27 = -3-27
5x = -30
Divide by 5
5x/5 = -30/5
x=-6
2(12-8x)=x-11x
Combine like terms
2(12-8x) = -10x
Divide by 2
12-8x = -5x
Add 8x to each side
12-8x+8x = -5x+8x
12 = 3x
Divide by 3
12/3 =3x/3
4=x
He would make more money with Susie than by himself because if he only works three hours and Susie make more money than him she would have more but if they work as a team they could split the money and get more together.
Answer:
I think its
im not sure
Step-by-step explanation:
<span>sin(36)(9) = 5.29
cos(36)(9) = 7.28
Area = (1/2)bh
Area = (1/2)(5.29)(7.28)
Area = 19 sq. in.</span>
