Step-by-step explanation:
3/8=x/20
Multiply both sides by 20.
20(3/8) = 60/8 = 15/2 = 7.5
7.5 = x
Answer:
i think its 8
Step-by-step explanation:
Let x = price for each cake and y = price of each pie in dollars.
We can get two equations out of the data. One from the Friday set, the other from the Saturday set.
Then, we subtract both equations. The difference would be:
-20y = -160
y = -160 ÷ -20
y = $8
Finally, we substitute y to any of the equations. Suppose, we use equation 1:
30x + 20(8) = 460
30x = 460 - 160
30x = 300
x = 300 ÷ 30
x = $10
Therefore, the cost for each cake and pie is $10 and $8, respectively.
Answer:
Step-by-step explanation:
Given expression:
<u>Partition</u> the mixed numbers into <u>fractions</u> and <u>whole numbers</u>, and then subtract them separately.
<u>Subtract</u> the whole numbers:
<u>Subtract</u> the fractions by changing both fractions into equivalent fractions so both fractions have the <u>same denominator</u>:
<u>Subtract</u> the numerator:
Put the two answers from the whole numbers and fractions back together:
Therefore:
