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?
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

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
What is Fourteen minus four times y is equal to y increased by 4

Answer:
hiii
Step-by-step explanation:
1. Multiply both sides by 3
38/3x x 3 +16/3. x =-20x3
2. Simplfy
38x+16=-60
3. Subtract 16 from both sides
38x+16-16=-60-16
4. Simplfy
38x=-76
5. Divide both sides by 38
38x/38=-76/38

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
