Answer: Adults = 58
Children = 42
Step-by-step explanation:
Let adults be denoted as a
Let Children be denoted as c
a + c = 100 ...... i
10a + 5c = 710 ...... ii
Multiply I by 5
Multiply ii by 1
5a + 5c = 500 ...... iii
10a + 5c = 710 ...... iv
Subtract iii from iv
5a = 210
a = 210/5
a = 42
Since a + c = 100
c = 100 - 42 = 58.
Adults = 58
Children = 42

Step-by-step explanation:
The dimensions of the new ( enlarged ) prism:
L = 5 * 2 = 10 cm,
W = 4 * 2 = 8 cm,
H = 3 * 2 = 6 cm.
The surface area of the prism:
S A = 2 LW + 2 LH + 2 WH
S A = 2 * 10 * 8 + 2 * 10 * 6 + 2 * 8 * 6
S A = 160 + 120 + 96
S A = 376 cm²
Answer: The surface area of the new prism is 376 cm².

Step-by-step explanation:
Here you go mate߷
Step 1߷
2(x - 1) = 4x + 3 Question߷
Step 2߷
2(x - 1) = 4x + 3 Simplify߷
Step 3߷
2(x - 1) = 4x + 3 Add 2 to sides߷
2x=4x+5߷
Step 4߷
2x=4x+5 subtract 4x from sides߷
-2x=5߷
Step 5߷
-2x=5 Divide sides by -2߷
answer߷
x=-5/2߷
Hope this helps߷
