x2 - 10x + 21 = 0
How do you work this problem?
Answer:
x = 3, 7
Step-by-step explanation:
Step 1: Write equation
x² - 10x + 21 = 0
Step 2: Factor
(x - 7)(x - 3) = 0
Step 3: Find roots
x - 7 = 0

Presley has to clean her 40-gallon fish tank. Her first step is to drain the tank. Using a hose and a
siphon, she finds that she can drain 16 gallons of water per hour.
Presley writes the equation 40 - 16x = 0, where x is the number of hours, to determine how many
hours it will take to drain the tank.
The next step Presley wrote to solve the equation is shown here:
40 = 16x
Which property did she use to get to this step?
a.) addition property of equality
b.) multiplication property of equality
c.) distributive property of equality
d.) combining like terms
Answer: The answer is A.addition property of equality

A Boy Scout troop is selling Christmas trees at a local tree lot in the morning they sold 11 Douglas fir trees and nine noble fir trees turning a total of $1006 in the afternoon they sold 14 Douglas fir trees and nine noble fir trees turning a total of $1111 how much do the Douglasfir trees cost
Answer:
$35
Step-by-step explanation:
Let x represent the price of Douglas fir trees and y represent the noble fir trees
11x + 9y= 1006........equation 1
14x + 9y= 1111.........equation 2
Multiply equation 1 by 14 and equation 2 by 11
154x + 126y= 14,084
-
154x + 99 y= 12,221
27y= 1863
Divide both sides by the coefficient of y which is 27
27y/27 = 1863/27
y= 69
Substitute 69 for y in equation 1
11x + 9y= 1006
11x + 9(69) = 1006
11x + 621= 1006
11x = 1006 -621
11x = 385
x = 385/11
x = 35
Hence the Douglas fir free costs $35

What is a slope of A and B
A.1/3
B.1/2
C.1/4
D.3/4
Answer:
A. 1/3
Step-by-step explanation:
to find slope (rise over run), you count how many points up and how many points over it is to get from one point to another on the line graphed.
from point A to point B, it is 4 up and 12 over (4/12). then, you have to simplify it, making it 1/3.
hopefully that helped! please consider brainliest! :)

8 waffle makers cost $200. If the waffle makers all cost the same amount, how much does each waffle maker cost?
Answer:
$25
Step-by-step explanation:
divide 200 by 8 to get the unit rate, or what a single waffle maker costs.
Answer:
Each waffle maker is $25.
Step-by-step explanation:
First set up an equation here mine would be:
200=8c (c being cost)
Next get c alone, so divide each side by 8. That gives you:
c=200/8
Simplify.
c=25
So the cost of each waffle maker is $25.

Founder's Park is planning to add a slide. The scaled model gives the reduced measures. A slide has a width of 3.5 inches and height of 3 inches. The park has space for the base of the slide to be 7-feet wide. To keep the slide proportional to the model, what will the height of the slide be? The slide will have a height of feet.
Answer: The slide will have a height of 6 feet.
Step-by-step explanation:
Given: A slide has a width of 3.5 inches and height of 3 inches.
For required slide , width = 7 feet]
To keep the slide proportional to the model,
[tex]\dfrac{\text{height of the required slide}}{\text{height of the slide }}=\dfrac{\text{width of required slide}}{\text{width of slide}}[/tex]
[tex]\Rightarrow\ \dfrac{\text{height of the required slide}}{3}=\dfrac{7}{3.5}\\\\\Rightarrow\ \dfrac{\text{height of the required slide}}{3}=2\\\\\Rightarrow\ \text{height of the required slide}=3\times2 =6\ \text{feet}[/tex]
hence, the slide will have a height of 6 feet.
Answer:
The slide will have a height of 6 feet.

Answer:
x = 2/3
Step-by-step explanation:
Lets solve your equation step-by-step.
x−10=−2(x+4)
Step 1: Simplify both sides of the equation.
x−10=−2(x+4)
x+−10=(−2)(x)+(−2)(4)(Distribute)
x+−10=−2x+−8
x−10=−2x−8
Step 2: Add 2x to both sides.
x−10+2x=−2x−8+2x
3x−10=−8
Step 3: Add 10 to both sides.
3x−10+10=−8+10
3x=2
Step 4: Divide both sides by 3.
3x / 3 = 2/3
x=2/3
