Answer: 1.25n
=======================================================
Explanation:
Erica sells bracelets for $2 each. If she makes and sells n of them, then she gets 2n dollars of revenue.
Making n bracelets cost her a total of 0.75n dollars because each bracelet costs 0.75 dollars, or 75 cents.
Subtract the revenue and cost to get the profit
profit = revenue - cost
profit = 2n - 0.75n
profit = (2-0.75)n
profit = 1.25n
The expression 1.25n means that she earns $1.25 in profit per bracelet sold.
Answer:
If the denominators are not the same: First, make them the same. Then add or subtract like fractions with the same denominators.
Step-by-step explanation:
the first step when multiplying fractions is to multiply the two numerators. the second step is to multiply the two denominators. simplify the new fractions. the fractions can also be simplified before multiplying by factoring out common factors in the numerator and denominator.
to add or subtract fractions they must have the same denominator. if the denominators are already the same then it is just a matter of either adding or subtracting the numerators if the denominators are difrent then a common denominator needs to be found.
You have to do whats in the parentheses from left to right then subtract the answer you get by 20
(9x10) - (30+30)
90 - 60 = 30
8 x (12+5) -7^2
17
17-49
18 x -32
= -576.
You have to use pemdas for your check off
P=parentheses
E=exponet
M=multiplication
D=division
A=add
S=subtrabt

Answer:
By applying Pythagoras theorem
Answer is √[109] inch
4x+5x = 90
9x = 90
x = 10
10y + 10 + 5x = 180
10y + 10 +5(10) = 180
10y + 60 = 180
10y = 120
y = 12
answer
<span>d) x = 10, y = 12</span>
