W=20 feet = 55% thus 20/55*100= L=36.36 Feet Fromula A=w*l
A=727.2 Feet²
First group rate is x+10, Second is x
First group made 160, Second made 120
Time the first group will take is 160/x+10, and second is 120/x
Equation is: 160/x+10 + 4 = 120/x
x=10, x=-30
The second group made 10 suits everyday.
Answer:
4 x 40 = 160, 160 x11= 1760+2= 1762
Step-by-step explanation:
5x-11=44
5x=55
x=11
hope that helps
Answer:
x=5, y=2
Step-by-step explanation:
You simply write down what you see:
3x - 4y + 4x - 5y = 17
2x - 3y + 3x - 5y = 9
Then you simplify by grouping the x and the y terms:
7x - 9y = 17
5x - 8y = 9
Now you want to get equal amounts of x or y. Let's go for x. If we multiply the top eq with 5 and the bottom one with -7, we get:
35x - 45y = 85
-35x + 56y = -63
-------------------------+ now we can add them:
11y = 22 divide by -11
y = 2
So 7x - 18 = 17, x =5
Finally, it makes sense to double check by filling in these answers in the original equations, just to see if no mistakes were made:
3*5 - 4*2 = 7
4*5 - 5*2 = 10
7+10 = 17: ok!
2*5 - 3*2 = 4
3*5 - 5*2 = 5
4+5 = 9: ok!
