Answer:
(x - 8) (x - 4)
Step-by-step explanation:
Find what adds to -12 but multiplies to 32
(x - 8) (x - 4)
Answer:
93+30=123 so e equals 123
Step-by-step explanation:
To check, do 123-30=93
Would you not just multiply all of the following numbers to get a total of 160?
Answer:
They biked for 1 hour and 38 minutes
Step-by-step explanation:
Here, we want to know the length of the biking time
Mathematically, from the time given;
if they had ended the biking by 2:47
They would have biked for 2 hours
But, as it can be seen, the biking stopped at 2:25 and that is (57-25 = 22 minutes earlier)
So, the length of their biking time would be;
1 hour and (60-22) minutes
and that is 1 hour 38 minutes
Answer:
1st: 116°
2nd: 64°
Step-by-step explanation:
Supplementary angles add up to 180 degrees. We can make the first supplementary angle be represented by: 2x - 12 and the second supp. angle be represented by x.
Make both of these expressions add up to 180.
(2x - 12) + (x) = 180
Combine like terms.
3x - 12 = 180
Add 12 to both sides.
3x = 192
Divide both sides by 3.
x = 64
Substitute 64 for x into the first supp. angle's expression.
2(64) - 12 = 116
The first supp. angle is 116 degrees and the second is 64 degrees.
