Answer: x=12
Step-by-step explanation:
we know that sum of a triangle is 180 degrees
one angle is 90 degree
the sum will be 90+(2x+1)+(5x+5)=180
substract 90 from both sides
2x+1+5x+5=180-90
7x+6=90
7x=90-6
divide by 7
x=12
If there is 8 boys then there is 12 girls because 2x4=8 boys so 3x4=12 girls.
Answer:
-1 Degree C
Step-by-step explanation:
When its talking about average temperature, its talking about the mean. To calculate mean, you add all the numbers and divide it by how many numbers are there.
(-8) + (-1) + 2 + 4 + (-2) = -5
mean = -5/5
-1 degree C

Answer:
Levi must sell more than 80000 cars per month for the new job to be better than the current job.
Step-by-step explanation:
New Job;
He receives $800 per month plus a commission of 2% or 0.02 of the total price of the cars.
Now, let the total amount he receives in a month be "y" and let the amount of cars sold be x.
Thus;
y = 800 + 0.02x - - - -(eq1)
Current Job:
He receives $1200 per month plus a commission of 1.5% or 0.015 of his total sales.
Thus;
y = 1200 + 0.015x - - - (eq2)
Substituting 800 + 0.02x for y into eq(2) gives;
800 + 0.02x = 1200 + 0.015x
0.02x - 0.015x = 1200 - 800
0.005x = 400
x = 400/0.005
x = 80000
This means Levi must sell more than 80000 cars per month for the new job to be better than the current job.
