Hi! Welcome to Brainly! Let's solve this word problem together below! :)
Let's write this as a system of equations.
8a+4s=880
a= s+20
Let's plug our a value into the first equation.
8(s+20)+4s=880
8s+160+4s=880
We combine like terms.
12s+160=880
We subtract 160 from both sides.
12s=720
We divide both sides by 12
s=60
Now, we plug this value into the second equation.
a= 60+20
a= 80
Therefore, 80 adult tickets were sold.
I hope this helps! Have a fabulous time here at Brainly! :)
34+38=72+90=162
180-162= 18
Round to the nearest tenth = 20

Answer:
≈ 3.6 x 10^1
Step-by-step explanation:
= (6.05 x 3.05) x 10^(5+4) / (4.27 x 1.2) x 10^(4+4)
= 18.4525 x 10^9 / 5.124 x 10^8
= (18.4525 / 5.124) x 10^(9-8)
≈ 3.6 x 10^1
Answer:
The correct answers are x + y = 5600 and x - y = 700.
Step-by-step explanation:
Write a system of equations in x and y describing the situation. Do not solve the system.
Keiko has a total of $ 5600, which she has invested in two accounts.
Let x be the amount of money in the larger account and y be the amount of money in the smaller account.
So, Keiko has invested her $5600 in two accounts x and y.
Thus x + y = 5600.
Also, given by the problem, the larger account (x) is $ 700 greater than the smaller account (y).
Thus x - y = 700.
Thus the two system of equation in x and y describing the given situation are
x + y = 5600 and x - y = 700
