Answer:
x=4
Step-by-step explanation:
1. isolate the variable by subtracting 7 on both sides: 4x=23-7
2. simplify: 4x=16
3. divide both sides by 4: x=16/4
4. simplify: x=4

Answer:
<u>112 children</u>
<u>180 adults</u>
Step-by-step explanation:
Let the number of adults = A
Let the number of children = C
A + C =292
4A + 1.5C = 888. solve for A, C
A = 292 - C
4[292 - C] + 1.5C = 888
1,168 - 4C + 1.5C = 888
-2.5C = - 280
C = -280 / -2.5
C = 112 - Number of children
292 - 112 = 180 - Number of adults
Answer:
12m^2+14m
Step-by-step explanation:
The "^means exponet" Hope I made your day
:)
Actual = 6 feet.
Measure = 5.49 feet
Error = 6 - 5.49 = 0.51
% Error = (Error / Actual) * 100%
= 0.51/6 * 100% = 8.5%
