Answer:
4 T-shirts and 5 long sleeves shirts.
Step-by-step explanation:
T-shirt cost =$10
Long sleeve shirt cost = $15
Total number of shirts = 9
Total number of T-shirts = 4
Cost of 4 T-shirts = 4 × 10 =$ 40
Total number of long sleeve shirt = 5
Cost of 5 long sleeve shirt = 5 × 15 =$ 75
Verification:
75+40 = $115 proved!
y = 3x - 1
x - y = -9
Subs y in second equation.
x - (3x - 1) = -9
x - 3x + 1 = -9
-2x = -9 - 1
-2x = -10
x = -10/-2
x = 5
Subs x
y = 3x - 1
y = 3.5 - 1
y = 15 - 1
y = 14
Answer:
x (11 unit) is the longest side
Step-by-step explanation:
Given:
Sides;
7, x, and x−1
Perimeter = 28
Find:
Longest side
Computation:
Perimeter = sum of all sides
So,
7 + x + (x -1) = 28
2x + 6 = 28
x = 11
So,
x -1 = 11 - 1 = 10 unit
x (11 unit) is the longest side
