Answer:
x = 4
QS = 20
Step-by-step explanation:
PS is all the numbers added together.
PQ + QR + RS = PS
(PLUG IN)
8 + 3x - 1 + 9 = 28 (collect like terms)
3x + 16 = 28 (subtract 16 on both sides)
3x = 12 (divide by 3 on both sides)
x = 4
QR + RS = QS
(PLUG IN)
3(4) - 1 + 9 = QS (distribute)
12 - 1 + 9 = QS (collect like terms)
20 = QS

Answer:
(0, 2)
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesAlgebra I
Solving systems of equations using substitution/eliminationSolving systems of equations by graphingStep-by-step explanation:
Step 1: Define systems
-2x - 8y = -16
2x - 7y = -14
Step 2: Solve for y
Elimination
Add 2 equations together: -15y = -30Divide -15 on both sides: y = 2Step 3: Solve for x
Define original equation: 2x - 7y = -14Substitute in y: 2x - 7(2) = -14Multiply: 2x - 14 = -14Add 14 to both sides: 2x = 0Divide 2 on both sides: x = 0Step 4: Graph

The expression for the number of cards Elijah owns is (1/3)x.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Number of cards Jeffrey owns = x
Elijah has one-third as many baseball cards as Jeffrey.

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as B
Now , the value of B is = number of boys
Substituting the values in the equation , we get
If three-fifths of the students are girls, then two-fifths must be boys, since the total fraction of students is equal to 1
On simplifying the equation , we get
To find the number of boys in the 7th grade, we can start by calculating the fraction of boys:
( 2/5 ) x 220 = 88
Hence , there are 88 boys in the 7th grade.

Find the area of the shape shown below plsss hurry I only have limited time
Answer: 32
Step-by-step explanation: so we can start by finding the two small ones at the bottom. so 2 times 2 is 4/2 is 2, 2 times 6 is 12/2 is 6. then we have a square in the middle that is 2 times 2 is 4. then to find the rest, we can add the 2, the 6, and because we know the bottom middle shape is a square, another two, so we end up with a line of 10 unites. then we can do 4 times 10 is 40/2 is 20. then we add all of our answers. so 20 plus 2 plus 4 plus 6 which is 32.
Answer:
32
Step-by-step explanation:
4*10 = 40/2 = 20
2*2 = 4/2= 2
2*2=4
6*2 = 12/2= 6
20+2+4+6 = 32
