Answer:
z is a variable so it can be any number.
z=-3
if you do -8 times -3 that equals 24.
the answer is -3
Step-by-step explanation:
Answer:
z stands for 3.
Step-by-step explanation:
First, subtract 12 from both sides.
-8z + 12 - 12 = -12 - 12
-8z = -24
Next, let's put brackets [] between both numbers. Any number inside of these becomes positive.
[-8z] = [-24]
8z = 24
Finally, let's divide doth sides by 8!
8z/8 = 24/8
z = 3
What is the answer to this equation 4(x-3)=20
Step-by-step explanation:
X=8 if that's what you are asking
Answer:
x=8
Step-by-step explanation:
First distribute the 4
4x-12=20
Then add 12 to both sides
4x=32
Then divide both sides by 4
x=8

The Salinas brothers, Juan and Carlos, have collected pledges for a bike rally they plan to have to raise money for their boy scout troop. Carlos's pledges total $11.50/mi and Juan's pledges total $9.75/mi. Carlos can peddle 10 mi/hr and Juan can peddle 12 mi/hr. If they plan to start and stop at the same time, how many hours will they have to bike if they want to raise at least $1000 together?
Answer:
5 hours
Step-by-step explanation:
Given that :
Juan:
Rate = 12mi/hr
$9.75/mi
Carlos :
Rate = 10mi/hr
$11.50/mi
To raise atleast $1000 altogether :
Let number of hours = h
Distance = rate * time
[(12*h) * 9.75] + [(10*h) * 11.50] ≥ 1000
[117h + 105h] ≥ 1000
222h ≥ 1000
h ≥ 1000/222
h ≥ 4.504
To earn atleast $1000 altogether, they must work for atleast 5 hours (nearest whole number).

A math teacher said that 18 out of 25 students passed the test what percent did not pass the test
Answer:
28%
Step-by-step explanation:
18/25=.72 ->72% passed the test, so then we take 100 and subtract 72 from it which leaves us with 28% that did not pass the test
Answer:
28% of students did not pass.
Step-by-step explanation:
18/25 = 72/100
72% passed.
So, if 18/25 students passed, (72%) then 7/25 students did not pass (28%)

A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position. The coordinates of G' are (-4,-1).
What are coordinates?A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position of points or other geometric components on a manifold such as Euclidean space.
Given the coordinates of G are (2,-4), now if the point is translated 6 units to the left and 3 units up. The new coordinates of G' are:
G' = (2-6, -4+3)
G' = (-4, -1)

)Elliot has been running a lawn care business since 2000. He cuts grass, trims, and weed whacks yards for his customers throughout the season. Each year, he has increased his fee by the same amount. The table shows what Elliot charged each customer for two given years of his business:
Year Lawn Care Fee
2000 $750
2010 $1350
A. What is the rate of change and initial value for Elliot’s business? How do you know?
B. Write an equation in slope-intercept form to represent the fees that Elliot charges each year.
Answer:
Rate of change = (1350 - 750)/(2010 - 2000) = 600/10 = $60
Initial value = $750
Equation is y = 60x + 750; where y is the amount charged to customer and x is the number of years from 2000.

-2(x-3)+4x = -(-x+1) SOLVE EQUATION AND SHOW STEPS ...NEED ANSWER NOW
Answer:
x=-7
Step-by-step explanation:
-2(x−3)+4x=−(−x+1)
Step 1: Simplify both sides of the equation.
−2(x−3)+4x=−(−x+1)
−2)(x)+(−2)(−3)+4x=x+−1(Distribute)
−2x+6+4x=x+−1
(−2x+4x)+(6)=x−1(Combine Like Terms)
2x+6=x−1
2x+6=x−1
Step 2: Subtract x from both sides.
2x+6−x=x−1−x
x+6=−1
Step 3: Subtract 6 from both sides.
x+6−6=−1−6
x=-7
