The solutions of the linear equations are below:
(1/3)*x + 7 = 3 + (2/3)*x is true if x = 12
5r−8=9r−12 is true if r = 1
(5/9)t− 27 = (1/9)t + 21 is true if t = 108
−(1/2)(−5y+4) = 2 + 1/2y is true if y = 2.
How to solve the linear equations?a) The first linear equation we have is:
(1/3)*x + 7 = 3 + (2/3)*x
To solve this, move all the like terms together (I will move the ones with x to the left side and the ones without x to the right side).
(1/3)*x - (2/3)*x = 3 - 7
Now we just simplify:
-1/3*x = -4
Now we isolate x:
x = -3*-4 = 12
x = 12
That is the solution of the linear equation, so remember, you just need to isolate the variable.
Let's do the same for the other ones:
2) 5r−8=9r−12
5r - 9r = -12 + 8
-4r = -4
r = -4/-4 = 1
r = 1
3) (5/9)t− 27 = (1/9)t + 21
(5/9)*t - (1/9)*t = 21 + 27
(4/9)*t = 48
t = (9/4)*48 = 108
4) −(1/2)(−5y+4) = 2 + 1/2y
Here we start by expanding the product in the left side, we will get:
(5/2)*y - 2 = 2 + (1/2)*y
(5/2)*y - (1/2)*y = 2 + 2
(4/2)*y = 4
2*y = 4
y = 4/2 = 2
y = 2
And so on, that is the general method to solve linear equations, just isolate the variable in one side of the equation and simplify the other side.

You deposit $3500 in an account that
earns 4% simple interest. How long will
you have to leave the money in the acount
to earn $350 interest?
Answer:
2years 6 months
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 4%/100 = 0.04 per year.
I = P × R × T/100
Solving our equation:
$350 = $3500 × 4 × T /100
Let's solve your equation step-by-step.
350=(3500)(4)t/100
Step 1: Multiply both sides by 100.
350=(3500)(4)t/100
(350)*(100)=((3500)(4)t/100)*(100)
35000=(3500)(4)t
Step 2: Simplify both sides of the equation.
35000=14000t
Step 3: Flip the equation.
14000t=35000
Step 4: Divide both sides by 14000.
14000t/14000=35000/14000
t=5/2
t = 2.5 years
2.5 years = 2years 6 months

If we add these number we get 21.31 is 21
When rounding numbers, there are several basic guidelines that must be observed.
We must first determine our rounding digit. This is the digit that will be affected in the end.
Following that, we must examine the digit to the right of this location, which will determine the fate of the rounding digit.
We do not modify the rounding digit if the digit to the right is less than 5. All digits to the right of the rounding digit, however, are altered to 0.
If the digit to the right is 5 or greater, the rounding digit is increased by one, and all digits to the right of the rounding digit are converted to 0.

Write the function, y=|x|
after the following transformations:
1) Reflect the function about the y-axis.
2) Compress the function vertically by a factor of 1/4.
3) Shift the function left 84 units.
The function, after the transformations is y'' = 1/4(x +84)
How to determine the function, after the transformations?The function equation is given as:
y = |x|
1) Reflect the function about the y-axis.
This is represented as
(x, y) = (-x, y)
So, we have:
y' = |-x|
This gives
y' = |x|
2) Compress the function vertically by a factor of 1/4.This is represented as
(x, y) = (x, 1/4y)
So, we have:
y'' = 1/4y'
This gives
y'' = 1/4|x|
3) Shift the function left 84 units.This is represented as
(x, y) = (x + 84, y)
So, we have:
y'' = 1/4(x +84)
Hence, the function, after the transformations is y'' = 1/4(x +84)

y = 5x - 3
10x - 2y = 7
Answer:
No solution
Step-by-step explanation:
First I plugged the value of y into the equation 10x-2y=, which gave me
10x- 2(5x - 3) = 7. Then you can distribute the -2 into the parenthesis giving you 10x - 2(5x)(-2 x -3) = 7. This leaves us with 10x- 10x + 6 = 7, because two negatives multiplied together form a positive. Now you subtract six from both sides to keep it equal, and you're left with 10x-10x= 1. This gives you 0= 1, which is not possible, so there is no solution.
We can check our work by putting 10x -2y= 7 into y=mx+b format, by subtracting 10x from both sides, leaving you with -2y = -10x+ 7. then you can divide out the -2, giving you y= 5x+ 7/5. Notice how the slopes in both our equations are 5x. This means that they are a group of parallel lines, bc they both stay at the same rate, despite having different y-intercepts or starting points.

The area of the remaining part of a large rectangle is 8m².
How to calculate the value?It should be noted that the original rectangle had sides of 8m by 6m.
In this case, it was stated that 4m was cut out from each side. The value of the remaining sides will be:
Area = Length × Width
Area = (8 - 4) × (6 - 4)
Area = 4 × 2

Take the vertical height
Smaller figure = 4
Larger figure = 8
So here the scale is 2
Scaling is inconsistent for different sides of the figure
So neither of them is right. For a figure to be scaled, all its sides must be scaled by the same number

What is linear equation?
A linear equation with one variable is one that contains just one variable. It has the formula Ax + B = 0, with A and B being any two real numbers and x being an ambiguous variable with only one possible value. One such linear equation in one variable is 9x + 78 = 18.Using the concept of proportional relationship, the time taken by Evian, Toby and J are 10, 9 and 12 minutes respectively.
Using the concept of proportional relationship :
For Evian :
1.5 miles = 15 minutes
1 mile = x
1.5x = 15
x = 15 / 1.5
x = 10 minutes
For Toby :
2/3 miles = 6 minutes
1 mile = x
2/3x = 6
x = 6 ÷ 2/3
x = 9 minutes
For J :
0.75 miles = 9 minutes
1 mile = x
0.75x = 9
x = 9 / 0.75
x = 12 minutes
Therefore, the time taken by Evian, Toby and J are 10, 9 and 12 minutes respectively.

The fundamentals of algebra taught us how to represent an unknown value using letters like x, y, and z. Here, these letters are referred to as variables. A mathematical expression may have both variables and constants. A coefficient is any value that is introduced before and increased by a variable.
Given that :The sum of a number x and 33 is greater than the product of 4 and that number.
x + 33 > 4x
33 > 3x
11 > x

A piece of cloth 7 ¾ yards long is to be cut into 5 pieces. How long will each piece be? Write your answer as an improper fraction yards
Answer:
35/20 yards
Step-by-step explanation:
We know the keyword “cut” means to divide, so we now know we have to use division.
7 3/4÷5/1
First, make 7 3/4 an improper fraction.
7 x 4 = 28
28+7= 35
Remember to keep the denominator.
35/4 ÷ 5/1
Then, use the method Keep, Change, & Flip.
(35/4)(1/5) = 35/20
Therefore…
Each piece will be 35/20 yards long.
