Twice Sam's age added to half her mother's age is 48. Three times her age less one third of her
mother's age is 33. How old are Sam and her mother?
Answers
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

Solve 4x + 1 = 3 – 2x
Answers
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
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.
Answers
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:

b=y-intercept
Answer: y = 2x - 5
slope-intercept form ⇒ y = mx + b
