I’m thinking your r in the first equation is actually an x.
X + 2(2x -4) =10
X +4x -8 =10
5x = 18
11km = 5h
1km = 5h divide by 11km = 0.45h
16.5km = 0.45 x 16.5 = 7.42 h
Answer:
11 minutes
Step-by-step explanation:
Because she types only 140 words in 4 minutes so if you add
140+140=280
if you divide
140/4 you get 35
so every minute she types in 35 words. So multiply
11 times 35 and you exactly get 385.
C=150•(3/5)•5
C=450
So if she ate the whole bag, she’d eat 450 calories.
116 degrees. It’s simple.
56 is what the low was, but the high was 60 more.
Therefore,
56+60=116
