Answer:$120
Step-by-step explanation:
85% of x= $107.27
.85x=107.27
Divide both sides by .85
X=126.20
Subtract the binder$6.20
The values in the table is linear function
Answer:
1/4 b^9
Step-by-step explanation:
(b^11 b^-7)/4b^-5
We know x^y * x^z = x^(y+z)
b^11 * b^ -7 = b^ (11-7) = b^4
(b^11 b^-7)/4b^-5
b^4 / 4 b^-5
We know x^y / x^z = x^(y-z(
b^4 / b^-5 = b^(4 - -5) = b^(4+5) = b^9
1/4 b^9
4t+2c=200
2t+7c=400
I will solve for c in terms of t first
4t+2c=200
2c=200-4t
c=100-2t
Then I will substitute this in for c in the second equation to make it single variable
2t+7c=400
2t+7(100-2t)=400
2t+700-14t=400
300t=12
t=25
Tables cost $25 each
Plug t back into one of the ORIGINAL equations to find the cost of chairs
4(25)+2c=200
100+2c=200
2c=100
c=50
Chairs cost $50 each
Hope this helps! :)
