Answer:
a=2
Step-by-step explanation:
Firstly, in order to simplify the expression, we should aim to combine the two terms given. In order to do this, both must have the same denominator. We can give them the same denominator by multiplying the second term by . This way the fraction value remains the same but now has the same denominator as the first term:
From here we can now combine the two terms:
Therefore, a = 2.
Hope this helped!
Answer:
x+85 + x+105 = 180
x = -5
x+85 = -5+85 = 80
x+105 = -5+105 = 100
Step-by-step explanation:
The two angles form a straight line so they add to 180
x+85 + x+105 = 180
Combine like terms
2x + 190 = 180
Subtract 190 from each side
2x+190-190 = 180-190
2x = -10
Divide by 2
2x/2 = -10/2
x = -5
x+85 = -5+85 = 80
x+105 = -5+105 = 100

Answer:
30 years
Step-by-step explanation:
Let :
Spike's age = x
Rex age = 6x
Rex mother = 10 * 6x = 60x
Rex father = 2 * 60x = 120x
x + 6x + 60x + 120x = 1000
187x = 1000
x = 1000/ 187
x = 5.34
Hence, Spike's age, x = 5 years
Rex age = 5 * 6 = 30 years
