What is a linear equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form linear equation is Ax+B=0.
Let the total charge be $x.
Now, x=8+(8-1)2
⇒x=8+14
⇒x=22
Therefore, the linear equation to determine the cost to ship 8 packages is x=22.

Answer:
A. 4
Step-by-step explanation:
For each of the values given for A, B, C, and D, you substitute the value in for m in the inequality.
2.5(4)+5 would have to be less than or equal to 25 in order for it to work. Well, 2.5x4 is 10 and then if you add 5, it is 15. 15 is less than 25, so 4 is the only value that works. The other numbers are too large if you substitute them into the equation.

Step-by-step explanation:
3/4=9/12 CORRECT
2/3=6/12 FALSE
Step-by-step explanation:
What is done to top of the fraction must be done to the bottom as well in order for the renaming to be true.
3*3 = 9
4*3 = 12
Therefore proven to be true
However,
2*3 = 6
but 3*3 = 9
The second fractions is renamed incorrectly and should be either 2/4=6/12 or 2/3=2/9

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,
Boy's age = x
Girl's age:
y = x + 3
Now,
x (x + 3) = 54
x² + 3x - 54 = 0
x² + (9 - 6) - 54 = 0
x² + 9x - 6x - 54 = 0
x(x + 9) - 6(x + 9) = 0
x - 6 = 0
x = 6
x + 9 = 0
x = -9 ( cannot be negative)
Now,
x = 9
Boy's age = 9
Girl's age = 9 + 3 = 12
Thus,
The boy's age and the girl's ages are 9 and 12.

d=
Answer:
[tex]d = 39[/tex]
Step-by-step explanation:
1) Multiply both sides by d.
[tex] \frac{20}{13} d = 60[/tex]
2) Simplify 20/13d to 20d/13.
[tex] \frac{20d}{13} = 60[/tex]
3) Multiply both sides by 13.
[tex]20d = 60 \times 13[/tex]
4) Simplify 60 × 13 to 780.
[tex]20d = 780[/tex]
5) Divide both sides by 20.

When we add the two equations, the y’s cancel out and we’re left with
6x=6
x=1
Now that we know x=1, we put it back in one of the equations to find y.
