Answer:
Sam is 15 and her mother is 36
Step-by-step explanation:
Let Sam's age be x and her mother's age by y
We can figure out Sam and her mother's age by representing these scenarios using equations with variables and solving the system using elimination
2x+y/2=48
3x-1/3y=33
You start by making all the numbers in both the equations whole
2(2x+y/2=48)
3(3x-1/3y=33)
Becomes:
4x+y=96
9x-y=99
Add together to eliminate y
13x/13=195/13
x=15
Now that we have x we can plug the value into the x in the equations to give us the y-value
2x15+y/2=48
30+y/2=48
30+y/2-30=48-30
y/2=18
2 X y/2=18 X 2
y=36
Therefore x=15 and y=36

Raven needs new winter boots. Both ShoeTown and LaceUp shoe stores carry the boots she wants to buy. The boots are regularly priced $85.95, but both stores are running sales. ShoeTown has the boots marked down 15%. LaceUp has the boots marked down 10%, plus Raven has a $5 coupon she can use on the boots after the mark down is applied.Raven’s friend, Becca, tells Raven there is an online shoe store called Run, Don’t Walk that has the boots she wants for only $71.99. If Raven buys the boots in a local store, she will have to pay 7.16% sales tax on her purchase. If Raven buys the boots online, she won’t have to pay sales tax, but she will have to pay $6.50 for shipping.
Raven should buy the boots at Shoe Town because this offers the best final price.
To determine which one is the best store for Raven let's calculate the price in each case.Shoe TownTotal price:
Initial price - Mark down + Sales tax
85.95 - 15% + 7.16 %85.95 - 12.89 + 7.16 %73.06 + 7. 16%73.06 + 5.23 = 78.29Lace UpTotal price:

Solve 4x + 1 = 3 – 2x
Answer:
x = 1/3
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
4x + 1 = 3 - 2x
Step 2: Solve for x
Add 2x on both sides: 6x + 1 = 3Subtract 1 on both sides: 6x = 2Divide 6 on both sides: x = 1/3Step 3: Check
Plug in x to verify it's a solution.
Substitute: 4(1/3) + 1 = 3 - 2(1/3)Multiply: 4/3 + 1 = 3 - 2/3Add/Subtract: 7/3 = 7/3Here we see that 7/3 does indeed equal 7/3.
∴ x = 1/3 is a solution of the equation.
Answer:
x=1/3
Step-by-step explanation:
4x+1=3-2x
Add 2x to both sides
6x+1=3
Subtract 1 on both sides
6x=2
x=2/6

Select the slope-intercept form of an equation for a line with y-intercept –5 and slope 2. A. x = 2x + 5 B. y = 2x – 5 C. y = 5x – 2 D. y = –5x + 2
Answer:
y=2x-5
Step-by-step explanation:
slope intercept form is y=mx+b
m=slope
b=y-intercept
Answer: y = 2x - 5
slope-intercept form ⇒ y = mx + b
⇒ where mx is the slope,
⇒ b is the y-intercept
⇒According to the question;
mx which is the slope = 2
b the y-intercept = -5
∴ the equation is

5, 18, 6, 18, 13 find the interquartile range (SHOW WORK)
Answer:
12
Step-by-step explanation:
The interquartile range is the difference between the upper quartile and the lower quartile.
Firstly find the median of the data.
The median is the middle value of the data arranged in ascending order. If there is no exact middle value then it is the average of the values either side of the middle.
5, 6, 13, 18, 18 ← data in ascending order
↑ middle value
median = 13
The upper quartile Q₃ is the middle of the data to the right of the median
13, 18, 18
↑ middle value
Q₃ = 18
The lower quartile Q₁ is the middle value of the data to the left of the median
5, 6, 13
↑ middle value
Q₁ = 6
Interquartile range = Q₃ = Q₁ = 18 - 6 = 12
