"raise at least $140" tells you that, whatever the variables may be, the french club's profit needs to be 140 or more
they're selling pastries at $3.50 each, so we'll say that p is the number of pastries
140 >/= 3.50p
$140 must be greater than or equal to the profit from sold pastries
then just solve the inequality from there by isolating your variable:
140 >/= 3.50p
divide both sides by 3.50
40 >/= p
so they must sell at least 40 pastries to raise $140 dollars
Answer:
n+30/5
Step-by-step explanation:
Simplify n/5
n/5+6
Rewrite the whole as an equivalent fraction
2.1 Add an integer to a fraction
Rewrite the whole as a fraction using 5 as the denominator: 6= 6/1=6×5/5
Equivalent fraction: the fraction thus generated looks different but has the same value as everything.
2.2 sum of the two equivalent fractions add two equivalent fractions that now have a common denominator
Combine the numerators, place the sum or difference over the common denominator, and then reduce to the lowest terms of possible:
n+6×5/5=n+30/5
Answer:
Step-by-step explanation:
<em>13/28 = 195/420</em>
<em>17/30 = 238/420</em>
<em />
<em>So that means that 3 17/30 > 3 13/28</em>
Initial value is when x=0
that is
f(0)=a(b^0) or
f(0)=a(1) or
f(0)=a
remember that x^0=1 for all values of x
Answer:
35i - 2
Step-by-step explanation:
(7 + 20i) - (9 - 15i)
distribute
7 + 20i - 9 + 15i
combine like-terms
35i - 2
hope this helps :)
