To find the answer, we can first find the age of Rolando in four year:
17+4
=21
We can then proceed to find the current age of Marisa,which is 3/2 of Rolando’s age calculated above:
Let Marisa’s age be y.
3/2 y =21
y = 21 × 2/3
y = 42/3
y = 14
Therefore Marisa is currently 14 years old.
In three years, Marisa would be:
14+3
=17
Therefore, she will be 17 years old.
Hope it helps!
Answer:
(1, 2)
Step-by-step explanation:
Subtract the second equation from the first:
(y) -(y) = (6x -4) -(-x +3)
0 = 7x -7 . . . . . simplify
0 = x - 1 . . . . . . divide by 7
1 = x . . . . . . . . . add 1
y = -1 +3 = 2 . . . substitute into the second equation
The solution is (x, y) = (1, 2).
Answer:
Step-by-step explanation:
0 = x2 + 3x - 10
10 = 2x+3x
10 = 5x
x = 2
0x = 5.2
0x = 10
x = 10.2 = 20
x = 20
0x = -5.-2
0x = -10
x = -10.2 = -20
x = -20
x = -5.2
x = -10
x = 5-2
x = 3
GOOD LUCK ! ;)
1 gallon = $7.44
1 gallon = 8 pints
∴ 8 pints = $7.44
1 pint = $0.93
