Answer:
48+2x=180
Step-by-step explanation:
This is an isosceles triangle, this means that two of the sides/angles are the same. I'm not 100% sure if I'm right though.
Answer: 17/60
Step-by-step explanation:
Change all of the fractions to have a common denominator:
LCM of 10, 12, 15 is 60
You get 12/60, 25/60, and 54/60.
54/60 is what he had at the start, and so you can just subtract what he gave away
54/60-12/60=42/60
42/60-25/60=17/60
17 is a prime number so you cannot simplify the fraction
Combining like terms would be defined as multiplying each term in a set of parentheses by the number outside of the parentheses.
Think of absolute value and inverse operation, +72 to 72 and 24
Plug -3 into the equation: w(-3)=14-6(-3)
simplify: w(-3)=14+18
solve: w(-3)=32
