What is Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
We have 10 hats and 20 masks were sold for $30.
and, 8 hats and 10 masks were sold for $18.
let the cost of one hat be H and cost one Mask be M.
So, the system of Equation we get
10H + 20M = 30..........(1)
8H + 10M = 18...........(2)
Solving the above equation we get
10H - 16H = 30 - 36
-6H = -6
H = 1
and, 10 + 20M= 30
20M= 20
M= 1

Martin is paid an hourly rate of d dollars per hour for the first 40 hours he works per week. He is paid one-and-a-half times his
hourly rate for each hour he works in excess of 40 hours per week.
If Martin was paid $770 for working 50 hours in one week, which equation can be used to calculate d, Martin's hourly rate of pay?
Answer:
40d + 10(1.5d) = 770 can be used to determine Martin's hourly pay.
Step-by-step explanation:
Given that:
Hourly rate = d
Earning to first 40 hours = 40d
Earning of more than 40 hours = 1.5d
Amount paid per week = $770
Hours worked = 50 hours
first 40 hours + 10 hours = total earned
40d + 10(1.5d) = 770
Hence,
40d + 10(1.5d) = 770 can be used to determine Martin's hourly pay.

Mt. Calvary's budget for a swing set to be built for the Children's Church is $900. If the cost of the swing set should be at least one-fourth as much as the fort, how much can be spent on the fort and still build the swing set?
Answer:
[tex]Amount = \$4500[/tex]
Step-by-step explanation:
Represent Swing Set with S and Fort with F
Given
[tex]S = \$900[/tex]
[tex]S = \frac{1}{4}\ of\ F[/tex] --- S = one-fourth of F
Required
Determine the amount spent on both
Substitute 900 for S in [tex]S = \frac{1}{4}\ of\ F[/tex]
[tex]\$900 = \frac{1}{4} * F[/tex]
Multiply both sides by 4
[tex]4 * \$900 = \frac{1}{4} * F * 4[/tex]
[tex]4 * \$900 = F[/tex]
[tex]\$3600= F[/tex]
[tex]F = \$3600[/tex]
The total amount to be spent it:
[tex]Amount = F + S[/tex]
[tex]Amount = \$3600 + \$900[/tex]
[tex]Amount = \$4500[/tex]

Robin had 7/8 pound of butter when she started baking a cake. She used 1/4 pound of butter while baking. How much butter was left after she was done baking?
Answer:
[tex]\dfrac{5}{8}[/tex] butter was left after she was done baking.
Step-by-step explanation:
Robin had 7/8 pound of butter when she started baking a cake. She used 1/4 pound of butter while baking.
We need to find how much butter was left after she was done baking.
It can be calculated as follows,
Left =
[tex]=\dfrac{7}{8}-\dfrac{1}{4}\\\\=\dfrac{7}{8}-\dfrac{2}{8}\\\\=\dfrac{7-2}{8}\\\\=\dfrac{5}{8}[/tex]
Hence, [tex]\dfrac{5}{8}[/tex] butter was left after she was done baking

Jake rewrites the expression 81x4 – 1 as a difference of squares so he can factor it. Which answer choice shows how Jake could rewrite the expression?
Answer: (9x^2)^2 -1^2
Step-by-step explanation:
Jake rewrite the expression as,
⇒ (3x - 1) (3x + 1) (9x² + 1)
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ 81x⁴ - 1
And, Jake rewrites the expression as a difference of squares so he can factor it.
Now, We can rewrite the expression as;
⇒ 81x⁴ - 1
⇒ (9x²)² - 1²
⇒ (9x² - 1) (9x² + 1)
⇒ ((3x)² - 1²) (9x² + 1)
⇒ (3x - 1) (3x + 1) (9x² + 1)

The distributive property also known as distributive law of multiplication and division.
In the given expression, distributive law of multiplication is applied where we can multiply first before addition.
Given
9(c+5)
Using distributive property
9(c+5)
= (9 × c) + (9 × 5)
= 9c + 45
9(c+5) = 9c + 45
