Answer:
pyramid with triangular base
1. 25% if 1/4, so we want to find 1/4 of 176. Best way to get the result is just divide 176 by 4, so 176:4=44 - its the answer.
2. To get the answer we can use proportion
100% -----------20
90% ---------- x
crossmultiply now
100x=90*20
100x=1800 /:100 divide both sides by 100
x=18 - its the answer
3. Similar problem
24 ---------- x
30 ---------- 100%
crossmultiply now
24*100%=30x
2400%=30x /:30 divide both sides by 30
2400%:30=x
80%=x - its the answer
Answer:
x = -7
Step-by-step explanation:
4 - 2(x - 3) = 24
Distribute
4 -2x +6 = 24
Combine like terms
10 -2x = 24
Subtract 10 from each side
10-2x-10 = 24-10
-2x = 14
Divide by -2
-2x/-2 = 14/-2
x = -7
