Answer:
See below.
Step-by-step explanation:
Ratios work like fractions. First we write the two ratios as fractions.
5/7 and 14/15
We can find a common denominator for these two ratios.
The LCD of the fractions is 7 * 15 = 105
Since 105/7 = 15, we multiply 15 * 5 = 75 to find the numerator.
5/7 = 75/105
Since 105/15 = 7, we multiply 7 * 14 = 98 to find the numerator.
14/15 = 98/105
75/105 is not equal to 98/105, so 5/7 is not equal to 98/105
35
12 + 25y = 795
12(y + 20) + 25y = 795
12y + 240 + 25y = 795
37y = 795 - 240
37y= 555
y=15
Substitute y= 15 into
x=y + 20
x= 15 + 20
x= 35
T-shirt = 35
Sweatshirt = 15
They brought 35 t shirts
Answer:
504
Step-by-step explanation:
