Joey has two pieces of wood. One is 120 inches and the other one is 210 inches long. He wants to cut both the pieces into smaller parts so that all these parts are of the same length.
i) If he wants the smallest pieces to be as long as possible without having any leftover, how long should each piece be?
Ans:
ii) How many smaller pieces of wood will he have in total?
Ans:
Answer:
A. 30 inches
B. 11 pieces
Step-by-step explanation:
Piece 1 = 120 inches
Piece 2 = 210 inches
1. He wants the smallest pieces to be as long as possible without having any leftover, how long should each piece be?
Find the highest common factor of 120 and 210
120: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, and 120.
210: 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210.
The highest common factor of 120 and 210 = 30
Therefore, the smallest and longest pieces should be cut into 30 inches each
B. Total Smaller pieces of wood = piece 1 / 30 + piece 2 / 30
= 120/30 + 210/30
= 4 + 7
= 11 pieces

Answer:
x = 1
y = 10
Step-by-step explanation:
5x + y = 15
Step 1: Move 5x on the other side by subtracting it from both sides
y = 15 - 5x
2x + y = 12
Step 2: Move 2x on the other side by subtracting it from both sides
y = 12 - 2x
Since y = y, that means 15 - 5x = 12 - 2x
Step 3: Add 5x to both sides
15 = 12 + 3x
Step 4: Subtract 12 from both sides
3 = 3x
Step 5: Divide both sides by 3
x = 1
y = 12 - 2x
Step 6: Plug in 1 for x
y = 12 - 2(1)
Step 7: Multiply 2 by 1
y = 12 - 2
Step 8: Subtract 2 from 12
y = 10
3xy + 4 – x – y + 2 + y + 5
3xy-x+11
Step-by-step explanation:
3xy+4-x-y+2+y+5
(add the common variables)
3xy-x+11

simplify by prime factorization 15/27
[tex]⟹ \: \cancel \frac{15}{27} = (3 \times 3 \times 3 \times 3 \times 3 ) \: (9 \times 9 \times 9)[/tex]
[tex] ⟹ \cancel \frac{15}{27} = 5(3) \times 9(3)[/tex]
[tex]⟹ \cancel \frac{15}{27} = \frac{5}{9} [/tex]
Therefore, when 15/27 is factorise using the method of prime factorization we'll get 5/9.

Solve for y
3x + 3y = 45
Answer:
y=15-x
Step-by-step explanation:
3y=45-3x
y=15-x
If you want to solve for y, you need another one equation
Answer:
y = -x + 15
Step-by-step explanation:
Subtract 3x from each side (left and right side of the equal sign) which will leave you with 3y = -3x + 45. Then divide everything by 3 which gets you
y = -x +15
What is 200 plus 200 plus 1,000 plus 6,000 equal to?
After you add those number subtract 1,200
But what 6,000 plus 200 equal??
Answer:
200+200+1,000+6,000 = 7,400 - 1,200 = 6,200
6,000+200=6,200
Step-by-step explanation:
so 200 plus 200 equal to 400 plus 1,000 equal to 1,400 plus 6,000 equal to 7,400 and then 7,400 subtract by 1,200 equal to 6,200.
and 6,000 plus 200 equal to 6,200.

How can we express numbers belonging to decimal numeral system?Suppose that the number is abcd.efg and belongs to the decimal numerical system.
Remember one thing that the place on the left of decimal point is called ones. Move one-one places to right, and divide by 10 and 10 more and more.
Move one-one places to left, and multiply (un-divide) by 10 and 10 more and more.
Thus, we write abcd.efg as:
[tex]a \times 10^3 + b \times 10^2 + c \times 10^1 + d \times 10^{0} + e \times 10^{-1} + f \times 10^{-2} + g \times 10^{-3}[/tex]
We will call d as ones digit, c as tens digit (it get multiplied by 10), b as hundreds digit etc.
We call e as digit at 10th place (division by 10), f as digit at hundredth place and so on.
Given;
Two decimal numbers; 2.7 and 2.8
Mid point=a+b/2
=2.7+2.8/2
=5.5/2
=2.75
Therefore, the mid value in decimal will be 2.75

PLEASE ANSWER THIS ASAP !!! ( turn sideways)
Answer:
C. y = -x
Step-by-step explanation:
the slope is -1 so in the formula y= mx + b
b is 0 and m is -1
so plug it in and you get y = -x
Slope is -2/5
and (-15.-7) Is on the line.
What is Y?
Answer:
The y-intercept is 0,-13 or y is -13
Step-by-step explanation:
I don't belive that you should use the method I use, but here it is.
times -2/5 by -15 and get 6 since its a negative slope it goes down 6 since it is also going forward on the axis leading to -7 minus 6 and getting -13.
PLS HELP! WILL MARK BRAINLIEST!!!
Answer:
8.8
Step-by-step explanation:
first set up the equation 2x+10=3x-13
then add 10 to -13 and add 2x to 5x so you get 5x=-3
then divide 5 from both side so you get x=-0.6
now that x=-0.6 you can solve 2x + 10 and that gets you 8.8.
8.8 is the measurement of angle 1 because it is directly opposite to 2x+10
Which quadrant will be completely shaded by the graph of the inequality y < 3x ?
A.Quadrant I
B. Quadrant II
С. Quadrant III
D. Quadrant IV
Answer:
D. Quadrant IV
Step-by-step explanation:
At first we need to graph the function [tex]y = 3\cdot x[/tex], whose representation is included in the figure attached below. The positive slope and the y-intercept equal to zero means that the inequality only takes any point below the line into account, that is, it covers Quadrants I and III partially and the Quadrant IV completely. Then, the correct answer is D.
