You don't have all the numbers, you don't know what X equals, you need to know what X equals in order to complete the equation
Answer:
Thy bought 150 Sweatshirts (x) and 250 tshirts (y)
Step-by-step explanation:
35x + 25y = 11500
x + y = 400
-25 (x + y = 400) Multiply by -25 to get the y's to disappear when you add the two equations together
-25x - 25y = 10000
<u> 35x + 25y = 11500 </u>
10x =1500
x = 150
Plug 150 in either equation for x to find y
150 + y = 400
y = 250
Answer:
444
Step-by-step explanation:
111x4=444
25 percent is equal to 1/4
The equation 3.3x - 6.6 = 2.7x is equal to the expression 0.6x = 6.6 (2nd option)
Smaller number=x
larger number=2x+4
x+2x+4=70
3x+4=70
3x=66
x=22
Smaller number=22
