Mai-li would have 2 3/8 material left over. I don't know if this is helpful anymore but here ya go :3.
7x+6x=650
13x= 650
Divide by 13
X= 50
She saves 7(50)= 350
She speeds 6(50)=300
The answer is C I am so sure
Let x denote the number of muffins Marian sells in a day to at least make a profit.
So $1.00 × x will be the amount of revenue Marian earns from selling bread (don't mix revenue with profit. Profit = Revenue - Cost)
In order for Marian to make a profit, revenue must be greater than cost in a day.
$1x > 0.8x + (square root)[5x + 7000]
x > 0.8x + (square root)[5x + 7000]
{ ">" this sign is saying "more than" }
0.2x > (square root)[5x + 7000]
{square both sides}
0.04x > 5x + 7000
-4.96x > 7000
4.96x < 7000
x < 7000 ÷ 4.96
Hope this helps you solve! :) So sorry for my wrong judgement earlier..
The top later is 5 because if the ladder is 10 inches half is 5 and the other half is 5
