6)
80+160+100+8x+8+5x+10=540
13x + 358 = 540
13x = 540 -358
13x = 182
x = 182/13
x = 14
answer x =14
7)
7x+13=8x-8
8x-7x=13+8
x = 21
answer x = 21
i think i is 56 do you have answer choices?
Answer:
3 m4 • sqrt(2m)
Step-by-step explanation:
STEP 1: Factor 18 into its prime factors
18 = 2 • 32
To simplify a square root, we extract factors which are squares, i.e., factors that are raised to an even exponent.
Factors which will be extracted are :
9 = 32
Factors which will remain inside the root are :
2 = 2
To complete this part of the simplification we take the squre root of the factors which are to be extracted. We do this by dividing their exponents by 2 :
3 = 3
At the end of this step the partly simplified SQRT looks like this:
3 • sqrt (2m9)
STEP 2: Rules for simplifing variables which may be raised to a power:
(1) variables with no exponent stay inside the radical
(2) variables raised to power 1 or (-1) stay inside the radical
(3) variables raised to an even exponent: Half the exponent taken out, nothing remains inside the radical. examples:
(3.1) sqrt(x8)=x4
(3.2) sqrt(x-6)=x-3
(4) variables raised to an odd exponent which is >2 or <(-2) , examples:
(4.1) sqrt(x5)=x2•sqrt(x)
(4.2) sqrt(x-7)=x-3•sqrt(x-1)
Applying these rules to our case we find out that
SQRT(m9) = m4 • SQRT(m)
Circumference of a circle = pi x diameter
pi = 3.14
diameter = radius x 2
diameter = 10 x 2
diameter = 20
Circumference = 3.14 x 20
Circumference = 62.8 ft
Answer:
They will have to borrow $ 31,211
(23% of the purchase price)
Step-by-step explanation:
Total price : $135,700
Down payment: 20% of total price
Closing costs : 3% of total price
The Colburns will have to borrow 23% of the total price.
0.23*$135,700 = $ 31,211
