Answer: 36 shirts and costs $432
step by step:
first make an equation with the amount of sold shirts being equal to cost of making them -
12x=10x+72 where x is the number of shirts
then, subtract 10x from 12x to get the variable on the same side -
2x=72
finally, divide by 2 to isolate x
x=36 shirts
to figure out the cost, substitute 36 for x in 10x+72
10(36)+72= 360+72= $432
135/100÷125/100
135/100×100/125
100cancel 100,it remains 135/125
135/÷5/125÷5
27/25=10.8
Answer:
4. -6
5. -5
6. 2
Step-by-step explanation:
4.
2x + 3 <= -9
2x <= -9 - 3
2x <= -12
= x <= -6
5.
3p + 4 > -11
3p > -11 -4
3p > -15
p > -5
6.
5x + 6 >= 16
5x >= 16 - 6
5x >= 10
x >= 2
