Answer:
C
Step-by-step explanation:
3/4 + 6/10
Find a common denominator and find what you multiply to each denominator to get that number and multiply the numerator by the same amount
(3/4 * 5/5) + (6/10 * 2/2)=
15/20 + 12/20
Then add
15/20 + 12/20= 27/20
Then finally convert to mixed number
27/20 = 1 7/20
13=3x-x/2
13=5x/2
26=5x
X=5.2
Answer:
127
Step-by-step explanation:
The angles add up to 180° since they are on a straight line. Find 3x - 5.
3x - 5 + x + 1 = 180
4x - 4 = 180
4x = 180 - 4
= 176
x = 176 ÷ 4
x = 44
3x - 5 = 3(44) - 5
= 132 - 5
= 127
Answer:
The drama club bought 35 t-shirt
Step-by-step explanation:
Let
t-shirt = x
Sweatshirt = y
Total cost = $795
They purchase 20 more tshirts than sweatshirts
x = y + 20
The equation is:
12x + 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
