your answer is going to be C
Answer: 1.37 miles
Step-by-step explanation:
13.7=100%
13.7/10=1.37=10%=1/10
-2+3x=2x+6+x
-2+3x= 3x+6
-3x = -3x
-2=6
No solution! -2 doesn’t not equal 6
Steps
1. Combine like terms( example combine like terms on the right side of the equation)
2. Subtract or add variable from one side
3. You get the answer
Answer:
12 : 37
Step-by-step explanation:
12 is the amount of small ones and 37 is the total number of t shirts
Since quadratic coefient is 1 (term in front of x^2)
take 1/2 of linear cofient (12) and square it
12/2=6, 6^2=36
add that to both sides
x^2+12x+36=-11+36
factor perfect square
(x+6)^2=25
sqrt both sides and take positiv and negative roots
x+6=+/-5
minus 6 both sides
x=-6+/-5
x=-6+5 or x=-6-5
x=-1 or -11
answer is {-11,-1}
