Answer:
Step-by-step explanation:
Distribute the parenthesis
Add 20 to both sides
Divide both sides by 2
Hope this helps
Answer:
To solve this we need to form 2 equations with only 2 variables.
x+4y-5z=-7
2x+y+5z=8
3x+5y=1
15x+10y+15z=35
6x+3y+15z=24
9x+7y=11
Now we need to use these to find x and y
9x+15y=3
9x+7y=11
8y=-8
y=-1
Therefore:
x=2
From this we can find that:
2(2)-1+5z=8
Therefore z=1
The answer is x=2, y=-1, z=1
Answer:
b = 36
Step-by-step explanation:
27 divided by 6 = 4.5
45 divided by 10 = 4.5
- so, each point was multiplied by 4.5
8 times 4.5 = 36
Answer:
Step-by-step explanation:
Average speed is distance divided by time.
s=(101km)/(1hr)
s=101 km/hr
Answer:
1) C = $25 + $40 × h
2) The domain for the ≠unction is 0 ≤ h ≤ ∞
The range for the function is 25 ≤ C ≤ ∞
3) Continuous
Step-by-step explanation:
1) The given parameters are;
The base fee charged = $25
The amount charged for labor = $40/hour
The total cost for h number of hours is C = $25 + $40 × h
2) The domain for the ≠unction is 0 ≤ h ≤ ∞
The range for the function is 25 ≤ C ≤ ∞
3) The situation is continuous because the different input values of h can be infinite (from o to infinity)
