Answer: b = 8
Step-by-step explanation: You have to divide (-4) on both sides and -32/-4= 8 so b =8
Answer:
Step-by-step explanation:
-32=4b
divide -4 by both sides
-4/-4=1
-32/-4=8
therefore, b=8

what is the value of y in the following system?
y=3x-5
6x+3y=15
Step-by-step explanation:
y=3x-5
6x+3y=15
6x+3(3x-5)=15
6x+9x-15=15
15x-15=15
+15 +15
15x=30
/15. /15
x=2
6(2)+3y=15
12+3y=15
-12. -12
3y=3
/3 /3
y=1
(2,1)
The answer is (2,1)
Step-by-step explanation:
6x + 3(3x - 5) = 15
6x + 9x - 15 = 15
15x - 15 = 15
+15 +15
15x = 30
/15 /15
x = 2
6(2) + 3y = 15
12 + 3y = 15
-12 -12
3y = 3
/3 /3
y = 1

A a book is originally priced at $65 the online retailer gives a discount and the book is now priced at $52 into the percentage discount for the cost of the book.
Answer:
20%
Step-by-step explanation:
Original price = $65
Current price = $52
Discount = $65 - $52
Discount = $13
The percentage discount is calculated as:
Discount/Original price × 100
= $13/$65 × 100
= 20%
The percentage discount for the cost of the book is 20%

The slope of a line is 2. The y-intercept of the line is –6. Which statements accurately describe how to graph the function?
Locate the ordered pair (0, –6). From that point on the graph, move up 2, right 1 to locate the next ordered pair on the line. Draw a line through the two points.
Locate the ordered pair (0, –6). From that point on the graph, move up 2, left 1 to locate the next ordered pair on the line. Draw a line through the two points.
Locate the ordered pair (–6, 0). From that point on the graph, move up 2, right 1 to locate the next ordered pair on the line. Draw a line through the two points.
Locate the ordered pair (–6, 0). From that point on the graph, move up 2, left 1 to locate the next ordered pair on the line. Draw a line through the two points.
Answer:
The answer is Locate the ordered pair (0, –6). From that point on the graph, move up 2, right 1 to locate the next ordered pair on the line. Draw a line through the two points.

You open a drink stand where you sell coffee and hot chocolate. You sell coffee for $1.80 and hot chocolate for $3.15. At the end of the day, you sold 120 cups and the total money you earned was $284.40. How many of each type of drink did you sell?
Answer:
c = 69 and h = 51
Step-by-step explanation:
You will need two different equations here
use variable c as coffee and variable h as hot chocolate
c + h = 120
1.80c + 3.15h = 284.40
By moving variables, you can alter the first equation
h = 120 - c
Now insert this into the second equation
1.80c + 3.15(120 - c) = 284.40
Multiply
1.80c + 378 - 3.15c = 284.40
Subtract the c
-1.35c + 378 = 284.40
Subtract 378 from both sides
-1.35c = -93.6
Divide both sides by -1.35
c = 69
Then plug into the first equation
69 + h = 120
Subtract 69
h = 51
You must bye one hundred eggs with 100 cents. There are three types of eggs and you will need to buy all three types of eggs.Goose eggs must be bought in multiples of twenty. 1 chicken egg costs 5 cents 1 duck egg costs 1 cent 20 goose eggs costs 1 cent How many chicken, duck and goose eggs do you need to buy?
Answer:
1 duck egg
19 chicken eggs
80 goose eggs
Step-by-step explanation:
Given that:
Goose eggs must be bought in multiples of 20
20 goose eggs = 1 cent
1 chicken egg = 5 cents
1 duck egg = 1 cent
Total amount to spend = 100 cents
Total number of eggs to purchase = 100
In other to ensure that 100 cents is spent and 100 eggs is purchased :
Using logical analysis :
1 cent is spent on duck egg, so 1 duck egg is purchased
Goose eggs (sold in multiples of 20) for 1 cent each ; 4 cents is spent on (20 * 4) = 80 goose eggs
100 - (4 + 1) = 100 - 5 = 95 cents is spent on chicken eggs ; 95 / cost per chicken egg = 95 / 5 = 19 chicken eggs
Hence,
1 duck egg = 1 cent
(20 *4) goose eggs = 80 eggs ; 4 * 1 = 4 cents
19 chicken eggs = 19 * 5cent = 95 cents
(1 + 80 + 19)eggs = (1 + 4 + 95)cents
100eggs = 100centa
Over 12 hours the water in Julie's pool drained a total of 534.72 liters. It drained the same number of liters each hour. What was the change in the number of liters of water in Julie's pool each hour and what is the unit rate
Given:
Over 12 hours the water in Julie's pool drained a total of 534.72 liters.
It drained the same number of liters each hour.
To find:
The change in the number of liters of water in Julie's pool each hour and what is the unit rate.
Solution:
We have,
Water drained in 12 hours = 534.72 liters
Water drained in 1 hour = [tex]\dfrac{534.72}{12}[/tex] liters
= [tex]44.56[/tex] liters
44.56 liters water drained in 1 hour.
So, the change in the number of liters of water in Julie's pool each hour is 44.56 liters.
The water is decreasing with respect to time, so the rate of change must be negative.
Rate of change = -44.56 liter per hour
Therefore, the rate of change is -44.56 liter per hour.

A cherry pie has a 16 inch diameter. What is its approximate area? Round to the nearest hundredth. (Use 3.14 for π)
Answer:
200
Step-by-step explanation:
Formula to find the area: πr²
First, find the radius: 16 ÷ 2 = 8
The radius is 8. So...
= 3.14 (8²)
= 3.14 × 64
= 200.96
Rounded to the nearest hundredth: 200
Answer:
200.96
Step-by-step explanation:
A=3.14r^2(formula for area of a circle)
r=16/2=8
r=8
A=3.14*8^2=200.96
