Jeff's shipping service charges $8 for the first package and $2 for each additional package. Use a linear equation to determine the cost to ship 8 packages.
Answer: 22
Step-by-step explanation:
The linear equation to determine the cost to ship 8 packages is x=22.
Given that, Jeff's shipping service charges $8 for the first package and $2 for each additional package.
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.

20/13 = 60/d
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.
[tex]d = \frac{780}{20} [/tex]
6) Simplify 780/20 to 39.
[tex]d = 39[/tex]
Therefor, the answer is d = 39.

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.

Answer:
B & C
Step-by-step explanation:
For A,
Base area(A) = length x breadth = 2m x 5m
Base area(A) = 10 m²
Similarly,
Base area(B) = 2m x 3m = 6m²
Base area(C) = 3m x 2m = 6m²
Base area(D) = 9m x 2m = 18m²
Note that 6m²=6m², B and C have same base area

Step-by-step explanation:
Given
[tex]Tin=231^\circ[/tex]
[tex]Oxygen=-218^\circ[/tex]
Required
The difference in their melting points
This is calculated as:
[tex]D = |Oxygen - Tin|[/tex]
[tex]D = |-281^\circ - 231^\circ|[/tex]
[tex]D = |-512^\circ|[/tex]
[tex]D = 512^\circ[/tex]
