if you add
22+35+26+17=100
well 100×10=1000
so just multiply 35 by 10= 350
= 9.71 Only way I could think of to solve it
Step-by-step explanation:
10x-72=3x-4

Step-by-step explanation:
She can solve 3 math problems in 4 mins
She can solve 1 math problem in = 4/3 *60 minutes= 80 secs
She has to solve 20 math problems = 20*80= 1600 secs/60= 26 mins and 40 secs.
She has 3 minutes and 20 secs to talk to her friends.
Answer:
The ratio of flour to sugar is 2:1
Step-by-step explanation:
Let f = weight of a bag of flour
Let s = weight of a bag of sugar
3f+2s = 32
4f = 32
We have 2 equations and 2 unknowns, we can solve
4f=32
Divide by 4
4f/4 = 32/4
f = 8
Each bag of flour weights 8 pounds
Substitute this back into the first equation
3(8) +2s = 32
24+2s = 32
Subtract 24 from each side
24-24 +2s =32-24
2s = 8
Divide by 2
2s/2 = 8/2
s = 4 pounds
Flours weighs 8 pounds and sugar weights 4 pounds
We want the ratio of flour to sugar
Flour: sugar
8:4
We can divide each side by 4
8/4: 4/4
2:1
