Let M equals to Mario's weight (M = Mario’s weight) then formulate an equation from the given phrase: "Victoria weighs 5/7 as much as Mario. Victoria weighs 125 lb", so the equation would be: 125 lb = (5/7) M. To solve for M, multiply both sides by 7, then it will result to 875 = 5M then finally, divide both sides by 5 to get Mario’s weight which is equals to 175 lbs.
You are given that XW and WT are similar and they share and angle W.
You need to know another set of sides are similar.
The answer would be C. VW ≅ RW
I have to write here as well apparently, but have added answer as picture
Answer:
"Dominic lived in Spain for 13 months and Columbia for 7 months."
Step-by-step explanation:
let months stayed in spain be "s" and months stayed in columbia be "c"
We can write 2 equations.
Since, lived in Spain and Columbia for a total of 20 months, we can write:
s + c = 20
Also, since 120 words per month in Spain and 150 words per month in Columbia for a total of 2610 new words, we can write:
120s + 150c=2610
Solving first for s:
s = 20 - c
Putting in 2nd and solving:
120(20 - c) + 150c = 2610
2400 - 120c + 150c = 2610
30c = 210
c = 7
Now,
s = 20 - c = 20 - 7 = 13
So
"Dominic lived in Spain for 13 months and Columbia for 7 months."
