Step-by-step explanation:
Let x be the son's age. The father's age is 3x and 3x - x = 24.
Therefore 2x = 24 and x = 12.
The son's age is 12 and the father's age is 36 at present.
Answer:
y = 90°
Step-by-step explanation:
You do 110° + 80° which is 180 divides by two because there is a straight line in the middle of it. I don't know how to explain it.
The solution to given system of equations is x = 2 and y = -5
<em><u>Solution:</u></em>
<em><u>Given the system of equations are:</u></em>
4x + y = 3 ---------- eqn 1
-2x + 3y = -19 ---------- eqn 2
We have to find the solution to above system of equations
<em><u>We can solve the system by substitution method</u></em>
From eqn 1,
4x + y = 3
Isolate y to one side
y = 3 - 4x ----------- eqn 3
<em><u>Substitute eqn 3 in eqn 2</u></em>
-2x + 3(3 - 4x) = -19
-2x + 9 - 12x = -19
Combine the like terms
-14x = -19 - 9
-14x = -28
Divide both sides of equation by -14
<h3>x = 2</h3>
<em><u>Substitute x = 2 in eqn 3</u></em>
y = 3 - 4(2)
y = 3 - 8
<h3>y = -5</h3>
Thus the solution is x = 2 and y = -5
Solution:
Let the bottle of sunscreen cost be $x. Then we can write
($x+ $6.50)+6%($x+ $6.50)=$16.43
Now solve this for x as below
Hence the bottle of sunscreen cost $9.
Answer:
move eight to the other side of the sign by subtracting it from both sides x>10
