The answer is 45 miles per hour. First, there are 60 minutes in one hour. So you divide 60 by 20, which equals 3. Knowing that, you multiply 15 by 3, which equals 45.
Answer:
The answer: 53x+13x=1313+83x
Step 1: Simplify both sides of the equation.
53x+13x=1313+83x
(53x+13x)=83x+1313(Combine Like Terms)
2x=83x+1313
2x=83x+1313
Step 2: Subtract 8/3x from both sides.
2x−83x=83x+1313−83x
−23x=1313
Step 3: Multiply both sides by 3/(-2).
(3−2)*(−23x)=(3−2)*(1313)
x=−1312
Answer:
x=−131/2
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
The arrow is going left four units. Since it's going left, we know that we are adding a negative number and since it's going left 4 units, we know that we are adding -4 in our equation. This narrows it down to options B and D. However, the arrow usually represents the second number being added, hence, the answer is B.
