Answer:
He is 2 years old.
Step-by-step explanation:
She is 22, in 8 years she will be 30. 30 is 3×10. At that time, her brother will be 10; that is 8 years from now. So now, the little brother is 10-8 = 2 years old.
If you must show algebra work:
x = brother's age now.
x+8=brother's age in 8 years.
YingYu's age in 8 years = 3 × brother's age in 8 years
22+8 = 3(x+8)
30 = 3x +24
6 = 3x
2 = x
Answer: Nope.
Step-by-step explanation: All circles are round and have no corners. Therefore, they cannot have any angles - right angles included.
Answer:
x = 3 and x = -2
Step-by-step explanation:
The given equation is :

We need to solve the given equation.
We can solve it using Completing the Square method.
We take two numbers such that their product is -6 and sum is -1.
So,

so, the values of x are 3 and -2.
2(2-3x)=3(3+x)+4
distribute
4 -6x = 9+3x+4
combine like terms
4 -6x =13 + 3x
add 6x to each side
4 = 13 + 9x
subtract 13 from each side
-9 = 9x
divide by 9
-1 = x
Answer x=-1
