Select all the equations that have the same solution as 2x - 5 = 15
A
2x = 10
B
2x = 20
C С
2(x - 5) = 15
D
2x - 20 = 0
E
43 - 10 = 30
F 15 = 5 – 22
Answer:
Step-by-step explanation:
2x - 5 = 15
Bringing like terms on one side
2x = 15 + 5
2x = 20
Option B is the correct answer
Answer:
b) 2x = 20
c) 2(x - 5) = 15
D) 2x - 20 = 0
Explanation
2x - 5 = 15
2x = 15 + 5
2x = 20
x= 20/2
x= 10
a) 2x = 10
x= 10/2
x= 5 (which is not correct)
b) 2x = 20
x= 20/2
x = 10 (which is correct )
c) 2(x- 5) = 15
2x - 10 = 15.
2x = 15 +10
2x = 20
x = 20/2
x= 10 ( which is correct)
d) 2x - 20 = 0
2x = 20
x= 20/2
x= 10 ( which is correct)

What is matrix?In mathematics, a matrix is a rectangular array or table of numbers, symbols, or expressions, arranged in rows and columns, which is used to represent a mathematical object or a property of such an object.
For example, is a matrix with two rows and three columns.
here, we have,
two matrices,
A = 2×3
and, B= 3×2,
as the no. of column of A = the no. of row of B
the can be a product matrix of order 2×2.
Now, we get,

, and comparing them to see that their HCF is

. Or, it can be done by dividing both numbers,

, then dividing the starting number with the new simplifiied number, remembering always to divide numerator with numerator and denominator with denominator.

This process works with any two numbers which you want to find the HCF of, and can be simplified into this rule:
If

c
d
is the simplified fraction of

Step-by-step explanation:
Mr. Chen is painting one wall of a room in his attic. He needs to detemine the area of the wall so he will know how much paint he will buy. The drawing below shows the dimensions of the wall.
Part A: Given the drawing, what is the area of the wall?
The area of the wall is
square feet.
Part B: If one quart of paint will cover 22 square feet, how many whole quarts will Mr. Chen need to buy?
He will need to buy
whole quarts.
Area of the figure
= (area of rectangle) + (area of triangle)
= (8 × 10) + (½ × 4 × 8)
= 80 + 16
= 96
Area = 96ft²
Quarts of paint needed
= 96/22
= 48/11
= 4.36
Mr. Chen will have to buy 5 quarts of paint.

Which equation is equivalent to x + 8 = 21? (x + 8) × 4 = 21 (x + 8) × 4 = 21 ÷ 4 (x + 8) × 4 = 21 × 2 (x + 8) × 4 = 21 × 4
Answer:
(x + 8) × 4 = 21 × 4
Explanation:
x + 8 = 21
21 - 8 = 13
(13 + 8) × 4 = 21 × 4
21 × 4 = 21 × 4
84 = 21 × 4
84 = 84

m = (change in y) / (change in x) = 8/0: undefined
Step-by-step explanation:
Note that the x-coordinate of both given points is the same: -2. This means that x does not change and also that y changes from -4 to 4. The slope is undefined because division by zero is not defined:
m = (change in y) / (change in x) = 8/0: undefined
The art teacher buys containers to store 1,314 colored pencils. Each container holds 18 pencils. How many containers does the art teacher need to store all the colored pencils?
Answer:
The art teacher needs 73 containers to store all the colored pencils.
Step-by-step explanation:
1,314 colored pencils ÷ 18 pencils per container = 73 containers total
The number of containers the art teacher need to store all the colored pencils is 73.
Given that, the art teacher buys containers to store 1,314 colored pencils.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Here, each container holds 18 pencils.
Number of containers = Total number of pencils/Number of pencils in each container
= 1314/18
= 73
Therefore, the number of containers the art teacher need to store all the colored pencils is 73.

Answer:
(-1, 4)
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesAlgebra I
Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define systems
10x + 6y = 14
-x - 6y = -23
Step 2: Solve for x
Elimination
Add 2 equations together: 9x = -9Divide 9 on both sides: x = -1Step 3: Solve for y
Define original equation: -x - 6y = -23Substitute in x: -(-1) - 6y = -23Multiply: 1 - 6y = -23Subtract 1 on both sides: -6y = -24Divide -6 on both sides: y = 4
