2x +100=16+4x
-2x. -2x
100=16+2x
-16. -16
84=2x
divide both sides
x=42
Answers:
<em>See below.</em>
Step-by-step explanations:
(A) This equation evaluates the cost to ship 100 lbs of wheat, which equals $130:
C(100) = 1.28(100) + 2
C(100) = 128 + 2
C(100) = 130
(B) The cost to ship 250 lbs of wheat would be $322:
C(250) = 1.28(250) + 2
C(250) = 320 + 2
C(250) = 322
(C) If you had $50, you could ship 37.5 lb of wheat:
C(x) = 50
C(x) = 48 + 2
C(x) = 1.28(37.5) + 2
The state sales tax in Colorado is 2.9%.
We know that because we divide 2.32/80. We have to find out what percent the tax is of the amount paid. The answer comes to 0.029. Multiply it by 100, and you get 2.9%
6)
KM bisects on <NKL so m<MKN = m<MKL = 3x + 5
2(m<MKL) + m<JKN = 180
2(3x+5) + 8x + 2 = 180
6x + 10 + 8x + 2 = 180
14x + 12 = 180
14x = 168
x = 12
so
m<MKN = m<MKL = 3x + 5 = 3(12) + 5 = 36 + 5 = 41
answer
b. 41
7)
2 supplementary has sum = 180
x + x + 14 = 180
2x + 14 = 180
2x = 166
x = 83
x + 14 = 83 + 14 = 97
2 angles are 83 and 97
answer
b. 83, 97
Answer:
2/4, 3/6, and 4/8
Step-by-step explanation:
Equivalent fractions are made by multiplying the numerator and denominator by the same factor.
For 1/2, you can multiply the top and bottom by 2, 3, or 4 to get 2/4, 3/6, and 4/8 respectively.
