Answer:
The answer is D, 47.1.
Step-by-step explanation:
Circumference is the diameter multiplied by pi, 15 * 3.14 is 47.1, so your current choice is correct.
The equation given is:
10 5/18 - 8 5/6
Turn the equations to improper fractions
[10*18 +5] = 185
[8 * 6 + 5]= 53
185/18 - 53/6
[185 - 159]/18 = 26/18
26/18 = 1 8/18.
Answer:
Step-by-step explanation:
Creating identical expressions involves changing quantities in a way that preserves the end values specified in the equation.
For instance, if Lei sold 4 carnations:
In the second equation listed, the expression (8 + 0.25c) was multiplied by 4, then by 0.25, for a total multiplicand of 1.
You can make a third equation through the same method. I'll multiply (8 + 0.25c) by 2, and then multiply that expression by 0.5 to keep the multiplicand unchanged:
If Lei sold 4 carnations:
0.5 * (16 + 2) = 9
This equation represents the same quantities as the other equations.
