Answer:
Subtract both sides by 7
Step-by-step explanation:
We have to make sure that we isolate the x term first. So we must subtract 7 from both sides.
Answer:
54 miles.
Step-by-step explanation:
Quinn runs 3 miles 3 times every week, which means he runs 9 miles every week.
We can multiply this by 6, which we get 54, so get the amount of miles Quinn runs in 6 weeks.
Step 1: Find out what 10 to the 5th power is equal to. it = 100,000
<span>Step 2: Multiply 100,000 by 10 </span>
<span>Step 3: your answer = 1,000,000</span>
9/6 or the simplified version is 1 1/2
Answer:
x = -1/2 ( 3±sqrt(37))
Step-by-step explanation:
x^2 + 3x − 7 = 0
Add 7 to each side
x^2 + 3x =7
Using complete the square
Taking the coefficient of x
3
Divide by 2
3/2
Square it
(3/2)^2 = 9/4
Add this to each side
x^2 + 3x+ 9/4 = 7+9/4
( x+ 3/2) ^2 = 28/4 + 9/4
( x+ 3/2) ^2 = 37/4
Take the square root of each side
x+3/2 = ±sqrt(37/4)
x+3/2 = ±sqrt(37) / sqrt(4)
x+ 3/2 = ±sqrt(37) / 2
Subtract 3/2 from each side
x = -3/2 ±sqrt(37) / 2
x = -1/2 ( 3±sqrt(37))
