Try writing and solving an equation of proportions:
4 5
---- = ----
6 x
Then 4x = 30, and x = 7.5 (answer)
19950/15=1330 they sold 1,330 tickets last year
1330*20=26600
if they sold the same amount of tickets as they did last year for $20 they would have 26,600 in sales.
Answer/Step-by-step explanation:
Let's find the measure of the angles of ∆QNP.
∆QMN is am isosceles ∆, because it has two equal sides. Therefore, its base angles would be the same. Thus:
m<MNQ = ½(180 - 48) (one of the base angles of ∆QMN)
m<MNQ = ½(132) = 66°
Next, find m<QNP
m<QNP = 180° - m<MNQ (linear pair angles)
m<QNP = 180° - 66° (Substitution)
m<QNP = 114°
Next, find m<P
m<P = 180 - (m<QNP + m<PQN) (sum of ∆)
m<P = 180 - (114 + 33)
m<P = 180 - 147
m<P = 33°
Thus, in ∆QNP, there are two equal angles, namely, <P and <PQN.
An isosceles ∆ had two equal base angles. Therefore, ∆QNP must be an isosceles ∆.
(7/8)*(9/10)=7*9/(8*10)=63/80
Answer: x=18
Step-by-step explanation:Based on the given conditions, formulate: 122.5+61.5 times x =2331.5
Rearrange unknown terms to the left side of the equation:
Calculate the sum or difference:61.5x=1107
Divide both sides of the equation by the coefficient of variable: x=1107 divided by 61.5
Calculate the product or quotient:x=18
get the result:x=18
