Three plus the quantity 4x times twelve
Answer:
26 child tickets
Step-by-step explanation:
4c = a to make the adult tickets equal to the child tickets multiply the child tickets by 4. then use substitution.
6.10c + 9.90(4c) = 1188.20
6.10c +39.6c = 1188.20
45.7c = 1188.20
c = 26
Step-by-step explanation:
2x = x1.2^n
2 = 1.2^n
log1.2(2) = n
log10(2)/log10(1.2) = n = 3.801784017...
so, rounded to the next whole year it takes 4 years.
Answer:
- Book -$20/11 and pencil - $17/11
Step-by-step explanation:
Let the set price of pencil be p and the set price of book be b
<u>Then we have equations:</u>
<u>Simplify the first equation:</u>
<u>And substitute p in the second equation: p = 7 - 3b</u>
- 4(7 - 3b) + b = 8
- 28 - 12b + b = 8
- 11b = 20
- b = 20/11
<u>And finding value of p:</u>
- p = 7 - 3(20/11) = 1/11(77 - 60) = 17/11
Answer:
-217 is the answer.
Step-by-step explanation:

eleven = 11
and from their product we have to subtract 8.
so,
-19×11
= -209
-209-8
= -217.
