So it is 7.18 times 10^7 is the same as
7.18 times 10,000,000
so we just move the decimal point 7 spaces to the right so
7.18 times 10^7=71,800,000
Answer:
its 6 because as you might know 10x6 is 60 so 60 divided by 10 is 6 :)
Answer: Angle 1 = 27
Angle 1 = 63
Remember: complementary angles always add up to 90 degrees.
Set up your equation.
3x + 7x = 90 Combine like terms
10x = 90 Divide by 10 to both sides
x = 9 Answer!
Substitute in (9) for x to find the measurements of the two angles.
Angle 1: 3x
3(9)
27
Angle 2: 7x
7(9)
63
You can also check your work.
27 + 63 = 90
3a - 6b = 3 • (a - 2b)<span> =
a-2b/4</span>
60 because area of a rectangle is l*b*w. So 6*2*5 will equal 60
