Answer:
X = 7
Step-by-step explanation:
180=90+4x+6+8x
84=12x
7=x
Answer:
520 - 303.93 - (10.99 * 4) - 25.25 - 73.43x ≥ 0
-
1) Parentheses
520 - 303.93 - 43.96 - 25.25 - 73.43x ≥ 0
-
2) Combine like terms
146.86 - 73.43x ≥ 0
-
3) Get the variable term alone
-73.43x ≥ -146.86
-
4) Divide to solve
x ≤ 2
** dividing by a negative number, the inequality sign flips **
ANSWER :
x ≤ 2
Answer:
Shanice
Step-by-step explanation:
<u>Michael</u>
4 1/4 times 3 = 12 3/4
<u>Shanice</u>
2 3/4 times 5 = 13 3/4.
Now we have to find the difference so
13 3/4 - 12 3/4 = 1
Therefore Shanice runs more miles in a week!

Step-by-step explanation:
<span>Because the four numbers are consecutive, we can call the first one x, and the other three are x+1, x+2, and x+3, respectively.
x * (x+1) = (x+2) * (x+3) - 38
x^2 + x = x^2 + 5x +6-38
x^2 + x = x^2 + 5x - 32
-4x = -32
x=8
The four numbers are 8, 9, 10, and 11
check solution: 8*9=10*11-38
72=110-38
72=72</span>
