Step-by-step explanation:
Ok, so first...
a) if x is positive, it will remain x, so *x<7*
b) if x+3 is positive, it will be x+3<9 but you have to simplify it so you subtract 3 on both sides and get *x<6*
c) if y-8 is positive, it will stay like that, and you then add 8 on both sides to get *y>19*
g) if 3x-1 is positive, it will be 3x-1 greater than or equal to 18. add 1 on both sides and *3x > or = to 18*
4y+3 < or = 13. subtract 3 on both sides and you get *4y < or = 13*
One more thing:
Less than or equal to is a '<' with a line underneath.
Greater than or equal to is a '>' with a line underneath.
A deluxe bakery sells a cookie for $4.01, a brownie for $4.1 and a cake for $30.54. On Wednesday they sold 13 cookies, 5 brownies and 3 cakes. The cost in ingredients for each cookie is $1.79, for,each brownie is $0.63 and for each cake is $6. 71. How much profit did they make on Wednesday?
Answer:
[tex]Profit = \$117.7[/tex]
Step-by-step explanation:
Given
Selling Price of:
[tex]Cookies = \$4.01[/tex]
[tex]Brownie = \$4.1[/tex]
[tex]Cake = \$30.54[/tex]
Quantities Sold:
[tex]Cookies = 13[/tex]
[tex]Brownies = 5[/tex]
[tex]Cake = 3[/tex]
Cost Price:
[tex]Cookies = \$1.79[/tex]
[tex]Brownie = \$0.63[/tex]
[tex]Cake = \$6.71[/tex]
Required
Determine the profit
First, we need to calculate the total cost price:
Total Cost Price = Item Cost Price * Quantity ---- For each
i.e.
[tex]Total\ Cost\ Price = \$1.79 * 13 + \$0.63 * 5 +\$6.71 * 3[/tex]
[tex]Total\ Cost\ Price = \$23.27 + \$3.15 +\$20.13[/tex]
[tex]Total\ Cost\ Price = \$46.55[/tex]
Then, the total selling price
Total Selling Price = Item Selling Price * Quantity ---- For each
[tex]Total\ Selling\ Price = \$4.01 * 13 + \$4.1 * 5 + \$30.54 * 3[/tex]
[tex]Total\ Selling\ Price = \$52.13 + \$20.5+ \$91.62[/tex]
[tex]Total\ Selling\ Price = \$164.25[/tex]
Profit is calculated as thus:
[tex]Profit = Total\ Selling\ Price - Total\ Cost\ Price[/tex]
[tex]Profit = \$164.25 - \$46.55[/tex]
[tex]Profit = \$117.7[/tex]

The Panthers baseball team needs new equipment. They plan to purchase bats that cost $60 each and gloves that cost $25 each. The number of bats they will purchase is half the number of gloves they will purchase. If they have $700, how many of each can they buy?
Answer:
Therefore, they can buy
6.36 bats and 12.72gloves
Step-by-step explanation:
Let us represent:
The number of bats purchased = b
The number of gloves purchased = g
We are told in the question that:
The number of bats they will purchase is half the number of gloves
b = 1/2g
b = g/2
g = 2b
The teams plan to purchase bats that cost $60 each and gloves that cost $25 each. they will purchase. If they have $700, how many of each can they buy?
Hence:
$60 × b + $25 × g = $700
= 60b + 25g = 700
We substitute 2b for g
60b + 25(2b) = 700
60b + 50b = 700
110b = 700
b = 700/110
b = 6.3636363636
b = 6.36 bats
Therefore, the number of bats they can buy = 6.36 bats
Remember:
g = 2b
b = 6.36
Hence,
g = 2 × 6.36
g =12.72
Therefore, the number of gloves = 12.72 gloves

Answer:
vanilla=$5 and fruit juice=$3
Step-by-step explanation:
let $x and $y denote the cost of vanilla thickshake and fruit juice respectively.
Now,
$x=$y+2$ (Given)-----(i)
3×$x + 5×$y =30
3×($y+$2)+5×$y=30 (From equation i )

If the length of a rectangle is g inches and the width is h inches:
Write two equivalent expressions to represent the perimeter of the rectangle.
If the width is 4. 7 in, and the perimeter is 68. 4in, calculate the length of the rectangle.
Perimeter: h + h + g +g = P or 2h + 2g = P
P = 2h + 2g
68.4 = 2(4.7) + 2g
68.4 = 9.4 + 2g
59 = 2g
g = 29.5
Length: 29.5 inches

Answer:
Please find the answer in the explanation
Step-by-step explanation:
Given that Jordan started at her home at point h she ran to the bank library post office at point B the café and then back to her home The coordinates the position in the miles of each of these locations with respect messenger tell which is located at the origin.
The total distance travelled will be the magnitude in miles from point h to B plus the magnitude in miles from point B to the cafe plus magnitude in miles from cafe back to point B plus the magnitude in miles from point B back to point h.
That is,
If the displacement from point h to b = x
And from B to the cafe = y
Then the total distance travelled will be
Distance = 2x + 2y

Problem 1
Slope = 3/4
Y intercept = -5
You have the right idea for the slope, but I would use a slash as shown above to indicate a fraction. It looks like you're subtracting 3 and 4 based on what you typed in. Though that might be the division symbol (it's a bit blurry so I can't see it fully/clearly)

The rate of change tells us how fast or slow that he's harvesting the crop. It's another way of saying his speed. The equation in this case is y = 14x+120 where 120 is the starting amount and its the y intercept. X represents the number of days, y represents the number of acres harvested.

Step-by-step explanation:
Ex.) y varies inversely with x. If x = -2 when y = -8, find y when x = -4.
Answer:
y = -4
Step-by-step explanation:
Since x and y vary inversely, we have:
xy=k
For x= -2 and y = -8, we have:
⇒ -2×-8=k
⇒ k= 16
For x= -4, we have :
⇒ -4y=16
⇒ y= 16/-4
⇒ y= -4
[RevyBreeze]
Answer:
y = -4
Step-by-step explanation:
The equation for inverse variation is
xy = k where k is a constant
x=-2 and y = -8 so we can find k
-2 * -8 = k
16 = k
The equation is xy = 16
Know we want to find y when x = -4
-4 *y =16
Divide each side by -4
-4y /-4 = 16/-4
y = -4
Wanda rides her bike 5 hours a week. How many hours does she ride in 4 weeks?
Answer:
20
Step-by-step explanation:
We can put the rate of hours a week as 5. Since in this case hours will substitute for distance, and distance=speed*time, then the amount of hours will be 5*4=20.
edit: mistyped
Answer:
20 hours
Step-by-step explanation:
Given the following question:
5 hours per week
How many hours does she ride in 4 weeks?
We know the amount of hours Wanda rides per week, so this is a simple multiplication problem.
[tex]5h\times4w[/tex]
[tex]5\times4=20[/tex]
[tex]=20[/tex]
Wanda rides her bike for "20 hours" in 4 weeks.

The ages of two groups of karate students are shown in the following dot plots:
(Imported image)
The mean absolute deviation (MAD) for group A is 2.07 and the MAD for group B is 5.51. Which of the following observations can be made using these data?
1. Group A has greater variability in the data.
2. Group A has less variability in the data.
3. Group B has a lower range.
4. Group B has a lower mean.
Thank you so much for your help! Xx
Answer:
From the graph and data points, you can observe that Group B has a HIGHER range and has a greater variability. so it's NOT 1. 4. or 3. THEREFORE it's 2.
Explanation:
You start out by finding the mean (finding the sum of the data values and then dividing the sum by the number of data values)
and subtracting the first plot by the last in each graph.

Carlie's sister works in a furniture store.
aCarlie's sister earns $35 per hour. The store offers her a raise a 3.5% increase per hour. After the raise,
how much will Carlie's sister make per hour?
Answer:
Step-by-step explanation:
Flat Raise: With a flat raise, you will determine how much additional money you would be getting as a flat sum, which adds to your annual salary. You can also figure out weekly, bi-weekly, or semi-monthly pay by dividing the yearly amount by the appropriate period. But if math isn’t your strong suit, our pay raise calculator will automatically determine that for you.
For example, let’s say that your gross annual wages are $30,000, with weekly payments of $577 going your way. You currently have 33 hours per week on average, and your employer proposes to give you a flat raise of $1,200. You want to determine how much their weekly pay will be and how much more you will ultimately receive. Add their current gross wages to the Current Pay with the Pay Period set to Annual. Insert the Flat Raise amount of $1,200 and press “Calculate.” You’ll get a new weekly payment of $600 with a total difference of $23.
