Answer:
x = 25
Step-by-step explanation:
2x-20=30
First, isolate the term with x in it by moving everything else to the other side:
2x = 30 + 20
Simplify like terms:
2x = 50
Further isolate the x by dividing by 2 on both sides:
2x/2 = 50/2
The 2 cancels out on the left, leaving:
x = 25
The error is 1.0 mile, too large.
Write the ratio
1.0 mile
--------------- = 0.069
14.5 miles
Mark's estimate is 6.9% greater than the actual distance.
Answer: Option A, B, E are correct.
A. 8^x •8^x = 64^x
B. 8^2x = 64^x
C. 8•8^2x = 8^{1 + 2x}
D.8^2•8^x = 8^{2 + x}
E. (8•8)^x = 64^x
F. 8•8^x = 8^{1 + x}
Hello from MrBillDoesMath!
Answer:
108 cm^2
Discussion:
The area of the logo =
area of Trapezoid on top (I) + area of triangle on bottom (II)
I = (1/2) h ( b1 + b2) h = altitude, b1, b2 = bases
= (1/2) 6 ( 6 + 12)
= (1/2) 6 ( 18)
= 54
II = (1/2) b h
= (1/2) (12) ( 15 - 6) => altitude of triangle = 15 - 6 NOT (1/2) 15
= 54
I + II= 54 + 54 = 108
Thank you,
