Answer:
x = 6
Step-by-step explanation:
We can see that the the 32 degree angle plus the equation (9x + 4) is equal to 90 degrees.
We know this because the bottom line is a 180 degree angle, and we can see on the other side that it is a right angle.
If we were to turn that into an equation it would like like this:
(9x + 4) + 32 = 90
Now you just have to solve for x.
9x + 4 + 32 = 90
Combine like terms:
9x + 36 = 90
Subtract 36 from both sides
9x = 54
divide both sides by 9
x = 6
and you are left with the answer.
Answer and Explanation:
Brielle will run the marathon faster.
Work:
Brielle: 13.1/1.25=10.48*10=104.8 minutes
Joshua: 13.1/1.5=8.73...*18=157.2 minutes
Brielle finished in 104.8 minutes.
Joshua finished in 157.2 minutes.
Brielle finished the half marathon race by 52.5 minutes faster than Joshua.
Hope this helps!!! PLZ MARK BRAINLIEST!!!
