Answer:
6u-9
Step-by-step explanation:
Multiply 3/4 by (8u-12). 3/4 of -12 is -9 and 3/4 of 8u is 6u.
Answer:
L = 8u-12
W = 3/4 (8u-12)
Or 3(8u-12)/4
Or 3(2u-3)
Or 6u-9
2(2u + 7) = 42
solve for u
simplify your answer as much as possible

After 4 hours, Samantha has 45 candies. After 6 hours, she has 35 candies.
Find the rate of change and explain what it means.
Answer:
2.922
Step-by-step explanation:
first, we have to find the unit rate to know how long it takes Samantha to make one candle. =
45 divided by 4=11.25 candles in an hour
then we will do the same for the other number.
35 divided by 6=5.8333...
the last step is to find the difference in time.
11.25-8.333-2.922
Answer:
The rate of change is 10 candies per hour.

y2 = 5
y1 =-2
x2 = 6
x1 = -8
m = (y2 - y1)/(x2 - x1)
m = (5 - - 2) / (6 - -8)
m = 7 / 14
m = 1/2

Step-by-step explanation:
MJ solved the equation -5x - 16 = 5
His work is shown below. Identify the error and where it was made.
-5x - 16 = 5
Step 1: -5x - 16 + 16 = 5 + 16
Step 2: -5x = 21
Step 3:
-5x5=215
Step 4: x = 215
Answer:
Step-by-step explanation: He add 16 together you are not suppose to add 16 you are suppose to add 5 together so instead of 16 + 16 you do 16+ 5

expand the expression: 1/4(36a + b)
Answer:
= 9a + 1/4b
Step-by-step explanation:
multiply by 1/4 or divide by 4, same thing.
9a + 1/4b
The expanded form of an expression 1/4(36a + b) is 9a + b/4 after applying the distributive property.
What is expanded form?The expanding form can be used to indicate the value of each digit in a number in arithmetic. Numbers that are expressed as the sum of each digit multiplied by its place value are known as expanded numbers.
We have expression:
[tex]\rm = \dfrac{1}{4}(36a + b)[/tex]
[tex]\rm = \dfrac{1}{4}\times36a +\dfrac{1}{4}\times b[/tex]
= 9a + b/4
Thus, the expanded form of an expression 1/4(36a + b) is 9a + b/4 after applying the distributive property.

Adi used algebra tiles to represent the product (negative 2 x minus 1)(2 x minus 1).
An algebra tile configuration. 4 tiles are in the Factor 1 spot: 2 are labeled negative x and 2 are labeled negative. 3 tiles are in the Factor 2 spot: 2 are labeled + x and 1 is labeled negative. 12 tiles are in the Product spot: 4 are labeled negative x squared, 4 are labeled negative x, 2 are labeled + x, and 2 are labeled +.
Which is true regarding Adi’s use of algebra tiles?
She used the algebra tiles correctly.
She did not represent the two original factors correctly on the headers.
The signs on some of the products are incorrect.
Some of the products do not show the correct powers of x.
Answer:
The correct answer would be
B) She did not represent the two original factors correctly on the headers.
Step-by-step explanation:
Adi algebra tiles representation is shown in the figure attached.
She made a mistake when she represented -2x-1 with two negative tiles in the top header , so, the representation in the header is not correct.
On the scale drawing of a car, the length from bumper to bumper is 6 inches. The car’s actual length, from bumper to bumper, is 16 feet.

Use the equation below to demonstrate these properties: $25.00 -$15.00 -$37.00 +$ 50.00= balance in bank account.
Answer:23
Step-by-step explanation:
A storm moves at a rate of 8 miles per hour. It is 200 miles away from Freeport and headed directly for this town. The equation y = 200 – 8x represents this function. What does the slope and y-intercept represent in this scenario?
Pls see answer below.
Step-by-step explanation:
In this case, our slope is -8. This means that every hour, the storm is getting closer to the town by 8 miles per hour.
Our y-intercept is 200, which means that its' initial position is 200 miles away from the town.
Hope this helped.
