None of them have a solution of x, but 5x=15, 7x-2=19, and 5x+6=21 all have the same answer of x=3
61% are sandwiches. it says it
Answer:
-175
Step-by-step explanation:
<u>STEPS:</u>
1) set up an equation. use x as a variable
2x + 3x = 25
2) solve the equation for x:
5x = 25
x = 5
3) Now that you know the value of x, substitute it into the expression for how any girls there are, which is "3x" (since the ratio of BOYS to GIRLS is 2:3):
3x
= 3(5)
= 15
So 15 is your answer, and there are <u>15 girls in the class.</u>
Square root of (-5-1)^2+(-4-4)^2
Square root of (-6)^2+(-8)^2
Square root of 36+84
Square root of 120
