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:
40
Step-by-step explanation:
Also, you find it by multiplying.
Answer:
-2y
Step-by-step explanation:
Let's simplify step-by-step.
x−y−(x+y)
Distribute the Negative Sign:
=x−y+−1(x+y)
=x+−y+−1x+−1y
=x+−y+−x+−y
Combine Like Terms:
=x+−y+−x+−y
=(x+−x)+(−y+−y)
=−2y
The triangle is a right triangle so use the Pythagorean theorem.
a² + b² = c²
15² + b² = 17²
225 + b² = 289
b² = 64
b = √64
b = 8
Hope this helps :)
Answer:
option 2: y - 5x + 3
Step-by-step explanation:
you would first distribute the 10 and then divide the entire left side by 2
