Answer:
x = 80
Step-by-step explanation:
Find a common denominator for 5/8x and 1/5x
25/40x + 8/40x = 66
Add 25/40x and 8/40x together.
33/40x
33/40x = 66
Divide both sides by 33/40
x = 80

A fraction represents a part of a whole.40/70, 21/70 are the same fractions like 4/7 and 3/10 with same denominator.
What is a fraction?A fraction represents a part of a whole
We need to write 4/7 and 3/10 with the same denominator
The given fractions are 4/7 and 3/10
in 4/7
If numerator and denominator is multiplied with 10
4/7*10/10
we get
40/70
i.e 4/7=40/70
Now
in 3/10
If numerator and denominator is multiplied with 10
3/10*7/7
we get
21/70
i.e 3/10=21/70
Therefore 4/7=40/70 and 3/10=21/70 are two fractions with same denominator.

gallons of water initially, write a function for the number of gallons of water, g(t),in the pool after t minutes
of pumping water into the pool.
Answer:
[tex]g(t)=8.25t+1250[/tex]
Step-by-step explanation:
You can input any value for t, and that would give you the amount of water pumped in. Then, the +1250 represents the initial 1250 gallons that are in the pool.

What is the slope for (-1,2) and (1,16)
Answer:
The slope is 7.
Step-by-step explanation:
(-1, 2) and (1, 16)
Slope is found using the following formula:
(y₂ - y₁) / (x₂ - x₁)
First, let's label the coordinates (these can be in any order, as long as the second numbers in each coordinate are in the y slots and the first numbers are in the x slots:
y₂: 16
y₁: 2
x₂: 1
x₁: -1
Now, substitute into the original formula:
(y₂ - y₁) / (x₂ - x₁)
(16 - 2) / (1 - (-1))
Simplify
(14)/(2)
7
The slope is 7.

Given
7x² - 3x - 6 ← substitute x = 3 into the expression
= 7(3)² - 3(3) - 6
= 7(9) - 9 - 6
= 63 - 15
= 48
Find a value for k such that the following trinomial can be factored x^2-8x+k
Answer:
16
Step-by-step explanation:
x^2-8x+k is a quadratic expression of the form ax^2 + bx + c. Here a = 1, b = -8 and c = k. Focus on x^2-8x and complete the square as follows: Take half of the coefficient of x (that is, take half of -8) and square the result:
(-4)^2 = 16; if we now write x^2-8x+ 16, we'll have the square of (x - 4): (x -4)^2.
Thus, k = 16 turns x^2-8x+k into a perfect square.

Step-by-step explanation:
California has 143deaths from heart disease and 137deaths from cancer per100,000 residents. Which rate is more extreme compared to other states? A.Perform any needed computations here: b. Is California's rate for heart disease or for cancer more extreme compared to the other states? Explain:
Answer:
California's rate for heart disease is more extreme than Cancer
Step-by-step explanation:
Given
Represent Cancer with C and Heart Disease with H
H = 143
C = 137
Population = per 100,000
First we need to determine the probability of both.
For H
P(H) = H/100000
P(H) = 143/100000
P(H) = 0.00143
For C
P(C) = C/100000
P(C) = 137/100000
P(C) = 0.00137
By comparison,
0.00143 > 0.00137
So, California's rate for heart disease is more extreme than Cancer.
Reason: P(H) > P(C)

ninth grade algebra.i am solving for x
Answer: x = 1
Step-by-step explanation:
So you need to get x completely alone, so take c out of it by subtracting c
-3x = -3 -2c
x = 1 +2/3c
so you would plug that in to solve for C
So you know what x is (or the substitute for it right now)
-3(1 + 2/3c) + 2c = -3
multiply or add
-3 - 2c + 2c = -3
c is 0 when you combine
-3x + 0 = -3
-3x = -3
x = 1
