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
3y - x = 6 (Note: the formula for slope-intercept form is y = mx + b)
3y = x + 6 (moving the x over to separate both variables)
y = x/3 + 6/3 (after dividing both sides by 3)
y = x/3 + 2 (simplify)
Hope this helps! :)
Answer:
D
Step-by-step explanation:
2² + 6² = x²
4 + 36 = x²
40 = x²
x = 2√10
