Answer:
Option E.
Step-by-step explanation:
Let the intended length of Rebecca's swimming is = x units
and we assume the length of the pool = l units
Now it is given in the question that " She covers one fifth of her intended distance "
That means distance covered = ![\frac{x}{5}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B5%7D)
" After swimming six more lengths of the pool she had covered one quarter of her intended distance"
So ![\frac{x}{5}+6(l)=\frac{x}{4}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B5%7D%2B6%28l%29%3D%5Cfrac%7Bx%7D%7B4%7D)
![6l=\frac{x}{4}-\frac{x}{5}](https://tex.z-dn.net/?f=6l%3D%5Cfrac%7Bx%7D%7B4%7D-%5Cfrac%7Bx%7D%7B5%7D)
![6l=\frac{x}{20}](https://tex.z-dn.net/?f=6l%3D%5Cfrac%7Bx%7D%7B20%7D)
x = 20×(6l)
x = 120l
Therefore, Rebecca has to complete 120 lengths of the pool.
Option E is the answer.
Answer:
3(x-1)+5(y-0.5)
Step-by-step explanation:
We dont know what the hot dog is worth and what the can of pop is worth, so lets say that a hot dog is x and 1 can of pop is y. the special was that the hot dogs were $1 of and the cans of pop were $0.50($0.5) off, so 1 hot dog is x-1 and 1 can of pop is y-0.5 Truman bought 3 hot dogs and 5 cans of pop, so the new equation would be 3*(x-1)+5(y-0.5)
We know that
1 milligrams is equals to-------------> 0.001 <span>grams
then
</span><span>3000 milligrams----------------------> X
X=3000*0.001------> x=3 grams
the answer is
3 grams</span>
Answer:
1548 lb
Step-by-step explanation:
Let the truck's weight be w.
Then (1/3)w = 516 lb
Solve for the truck's weight by multiplying both sides of this equation by 3:
w = 1548 lb (Answer B)
