This is what I got:
60/50 = X/70
70x60/59 = X
X = 84
7.96 / 6 = 1.33 <== unit rate
Answer:
The sides are 3, 4, and 5
Step-by-step explanation:
Let one side be 'n', if the side lengths are consecutive integers, we have
n
n + 1
and
n + 2 are our side lengths. adding 1 to n gives us the next integer. Adding 2 to n gives use the second consecutive integer to n
The perimeter is 12, so our equation is..
n + (n + 1) + (n + 2) = 12
Now combine like terms and solve..
n + n + 1 + n + 2 = 12
3n + 3 = 12
3n = 9 (subtract 3 from both is sides)
n = 3 (divide by 3 on both sides)
Since n = 3,
n + 1 = 4 and
n + 2 = 5
So the sides are 3, 4, and 5
Answer:
24 carbohydrates
Step-by-step explanation:
Represent Snack bars with S and Milks with M.
So, we have:
and
Required: Solve for M and S
Convert the given expressions to mathematical expressions:
--- (1)
--- (2)
Multiply the first equation by 2
--------- * 2
--- (3)
Subtract (1) from (3)
Solve for S
Substitute 13 for S in (2)
Solve for 4M
Solve for M
1 glass of milk and 1 snack bar = S + M
