Answer:
9/10
1/2+2/5
Since these fractions have different denominators, we need to find the least common multiple of the denominators.The least common multiple of 2 and 5 is 10, so we need to multiply to make each of the denominators = 10
1/2 ∗ 5/5 = 5/10
5/2∗ 2/2= 4/10
Since these fractions have the same denominator, we can just add the numerators
5/10+ 4/10 = 9/10

Answer:
x = 60
1) 60
2) 360
3) 160
60 + 360 + 160 = 580
Step-by-step explanation:
1) x
2) 6x
3) x + 100
x + 6x + x + 100 = 580
8x = 580 - 100
x = 480/8
x = 60
Answer:
52 years
Step-by-step explanation:
Let
Your age = x
3 times your age = 3 * x
= 3x
The equation can be written as:
400 - 3x = 244
400 - 244 = 3x
156 = 3x
Divide both sides by 3
x = 156/3
x = 52
Therefore,
Your age is 52 years
Answer:-55
Step-by-step explanation:-300 + 245 = -55
