Answer:
34
Step-by-step explanation:
plug the coefficients in the equation, so
-2-2(-2)(-5)+56
Distribute the -2(-2)(-5), so it equals -20
so the equation is -2-20+56
add -20+56, so -2+36
-2+36=34
34 is your answer
Well...what are the expressions and phrases???
After the total distance on the first, second and third days, Patrick had walked 3.45miles
First, subtract 30x from each side to get:
-60 = -10x
Then, divide each side by -10 to get:
x = 6
Now, plug back in to check your answer:
30(6) - 60 = 20(6)
180 - 60 = 120
120 = 120
Hope this helps!! :)
