Answer:
A = 340 adult.
C = 398 children.
Step-by-step explanation:
Let the number of children be C
Let the number of adults be A
Translating the word problem into an algebraic equation, we have;
A + C = 738 .......equation 1
1.5C + 2C = 1306 .......equation 2
A = 738 - C .......equation 3
Substituting eqn 3 into eqn 2, we have;
1.5(738 - C) + 2C = 1306
1107 - 1.5C + 2C = 1306
1306 - 1107 = 2C - 1.5C
199 = 0.5C
C = 199/0.5
<em>C = 398 children. </em>
Now, to find the value of A.
From equation 3;
A = 738 - C
A = 738 - 398
<em>A = 340 adult. </em>
Answer:
1) 11
2) 15
Step-by-step explanation:
The bars on the sides of the numbers represent the absolute value/magnitude of the number, so you will need to remove the negative symbol if it is present in front of the number (if it is already a positive number, leave it as it is).

$138494.7
Step-by-step explanation:
170828-73828=97000
97000÷12=8083.3
8083.3= the amount the house depreciated every year
8083.3×4 =32333.3
170828-32333.3= $138494.7
Answer:
25 percent
Step-by-step explanation:
6 divided by 24
2x + 8 = 50
Subtract 8 from both sides
2x = 42
Divide both by 2
x = 21
