Answer:
Step-by-step explanation:
c
<span>the formula d = rt
</span><span>
r = d/t (</span>c. d over t = r<span>)
</span>t = d/r (a. d over r = t)
d = rt (<span>d. d over rt = 1)
</span><span>
so answer
</span>b. r = dt ......not equivalent to the formula d = rt
Answer:
Brenda ran 263.76 metres.
Step-by-step explanation:
The circumference of a circle is two times pi times its radius. Brenda rand that twice, so we need:
2 × 2πr
= 4πr
= 4 × 3.14 × 21m
= 263.73m
There is 2000 pounds in 1 ton
10000/2000 = 5 tons
14000/2000 = 7 tons
The range in tons is 5 - 7 tons
hope this helps
Answer:
I understand what you wrote as 18 + M = y. We don't know what M and y are. They are variables. When you add M to 18, it is equal to a value y.
I hope this makes sense. This is the foundation of algebraic thinking.
