What is the missing numerator? 8 5 3 2
Answer:
3
Step-by-step explanation:
if you put 3 into the numerator you can evaluate the equation.
by placing 3 in the numerator, you can then create a common denominator (20) which also changes the value of 3 to 12.
12 + 18 =30

A painter ordered 3 gallons of red paint for $35 per gallon. He ordered 5 gallons of blue paint for $39 per gallon. What is the total cost of both kinds of paint?
Answer:
$300 is the total cost for both kinds of paint
Step-by-step explanation:
1) Start by breaking down the problem so it was more simple
- Red paint is $35 per gallon; blue is $39 per gallon
2) Since it is by gallon, you will multiply the number of gallons by the cost for each to get the total cost of each
- 35 * 3 = $105 for 3 gallons of red paint
- 39 * 5 = $195 for 5 gallons of blue paint
3) Total cost together; you will add the total cost of red and blue paint together
- 105 + 195 = $300

a 36 oz. container of punch costs 2.99 and a 48 oz. container costs $3.75 which is the better buy
Answer:
The 36 oz container
Step-by-step explanation:
Just divide the container size by its price and smallest number is the better price
Answer:
Step-by-step explanation:
You just have to divide the container size by the price and you will get the answer. Which ever price is smaller that is the better deal.
in a hypothesis test, if the computed p-value is less than 0.001, there is very strong evidence to
Answer: reject the null hypothesis
Explanation:
If the p-value is smaller than the significance level alpha, then we reject the null. You can think of the p-value being the probability that the null is correct. If the p-value is below a certain threshold (the significance level), then we can be fairly confident that rejecting the null is a good decision.
Your teacher or textbook might have brought up the phrase "If the p-value is low, then the null must go" as a way to help remember this rule. If the alpha level isn't stated, then usually it defaults to 0.05

A tortoise moves at a speed of 34 inches in 11 seconds. What is its average speed in feet per hour?
Answer:
927.3 feet per hour
Step-by-step explanation:
first determine how many seconds are in one hour
there are 60 seconds in one minute and 60 minutes in one hour
so there are 60x60, or 3600 seconds in one hour
now you can create a proportion of inches/seconds = inches/seconds
let 'x' = inches per hour
34/11 = x/3600
cross-multiply to get:
11x = 3600x34
11x = 122,400
x = 122,400/11
x = 11,127.3 inches per hour
to determine how many feet per hour you must divide 11,127.3 inches by 12
this equals 927.3 feet per hour

5 more than a number is 21. Write it in an equation.
Answer:
5 + x = 21
Step-by-step explanation:
5 more than a number is 21. Write it in an equation.
5 + x = 21
-------------------------
Answer:
5+x=21
Step-by-step explanation:
A number 5 is the number added to the variable "X".
----> x+5=21. Hence “5 more than a number is 21. ” written as an algebraic expression is “x+5”.
So a number 5 more than x is 21 means that if you add x+5, you recive 21

Work Sample Question - Justify your answer mathematically to earn full credit.
Convert the linear equation written in Standard Form (Ax + By = C) to Slope-Intercept Form (y = mx +b). To earn full credit you must show all mathematical steps to justify your final equation. The expectation is for students to rewrite the original equation, show transforming the equation, and stating the final equation in Slope-Intercept Form (y = mx + b).
Standard Form: -8x - 2y = -24
Answer:
y = -4x + 12
Step-by-step explanation:
-8x - 2y = -24
Add '2x' to both sides
-2y = 8x - 24
Divide the entire equation by (-2)
[tex]\dfrac{-2y}{-2}=\dfrac{8x}{-2}-\dfrac{24}{-2}\\\\[/tex]

given m=a+b+c which equation represents c in terms of the other variables?
Answer:
m - a - b = c
Step-by-step explanation:
m = a + b + c
-a = -a Add -a from both sides
m - a = b + c
-b = -b Add -b from both sides
m - a - b = c

Line P passes through the point (3,4) and is Perpendicular to the line with equation 3x+2y=8. What is the equation for line p?
Answer:
y = 2/3x + 2
