Ok, so first you solve whatever is in the parentheses.
(28 • 5-5 • 190)-2•228
28• 5 = 140
Then 5 •190 = 950
Then multiply 950 • 140 = 133,000
Then it should look like this:
133,000-2•228
Multiply 2 • 228 = 456
Then subtract 456 from 133,000.
The answer should come out to 132,544.
Answer:
i think the 2nd one
Step-by-step explanation:
Hi!! Okay thanks! And yes I think that’s correct.
<u>What do we know so far</u>:
*we converted the number of laps into improper fractions
![2\frac{2}{3} = \frac{8}{3}](https://tex.z-dn.net/?f=2%5Cfrac%7B2%7D%7B3%7D%20%20%3D%20%5Cfrac%7B8%7D%7B3%7D)
<u>We want to know the number of laps in an hour</u>
⇒ so we must find the rate which ⇒ lap/hour
![lap/hour =\frac{8/3laps}{4/15hours} =\frac{8}{3}*\frac{15}{4} =\frac{8}{4} *\frac{15}{3} =2*5=10laps/hour](https://tex.z-dn.net/?f=lap%2Fhour%20%3D%5Cfrac%7B8%2F3laps%7D%7B4%2F15hours%7D%20%3D%5Cfrac%7B8%7D%7B3%7D%2A%5Cfrac%7B15%7D%7B4%7D%20%20%20%3D%5Cfrac%7B8%7D%7B4%7D%20%2A%5Cfrac%7B15%7D%7B3%7D%20%3D2%2A5%3D10laps%2Fhour)
<u>So William can run</u> ⇒ <u>10 laps in one hour</u>
Hope that helps!
