Answer:
<em>The</em><em> </em><em>answer</em><em> </em><em>is</em><em> </em><em>x</em><em> </em><em>-</em><em> </em><em>y</em><em> </em><em>=</em><em> </em><em>7</em>
Step-by-step explanation:
<em>2x</em><em> </em><em>-</em><em> </em><em>2y</em><em> </em><em>=</em><em> </em><em>14</em><em> </em>
<em>2</em><em>(</em><em>x</em><em> </em><em>-</em><em> </em><em>y</em><em>)</em><em> </em><em>=</em><em> </em><em>14</em><em> </em>
<em>x</em><em> </em><em>-</em><em> </em><em>y</em><em> </em><em>=</em><em> </em><em>14</em><em>/</em><em>2</em>
<em>x</em><em> </em><em>-</em><em> </em><em>y</em><em> </em><em>=</em><em> </em><em>7</em><em> </em>

We can make two simple equations to express their ages to each other, then solve for one of the variables. Let n be Nojo's age and j be Jacob's age.
n(j) = 84
n - 5 = j
Use substitution to get only one variable in an equation.
n (n - 5) = 84
n^2 - 5n = 84
Since we have n to the power of 2, this equation has two possible answers, but since we are given four possible answer, just substitute them in the equation until one makes the left side equal 84.
<span>n^2 - 5n = 84
</span>12^2 - 5 (12) = 84
144 - 60 = 84
84 = 84
The answer is C = 12
Answer:
233.37
Step-by-step explanation:
so between each gondola is 20.95 so you will multiply it by 35 not 36 (because between the first you go round and come back to the same first you started so no space between first and last) then get circumference as 733.25 using

you get diameter
The solution to system is x = 0 and y = -1
<em><u>Solution:</u></em>
<em><u>Given system of equations are:</u></em>
-8x + 2y = -2 ----------- eqn 1
4x + 4y = -4 ---------- eqn 2
We have to solve the system of equations
We can solve the equations by elimination method
<em><u>Multiply eqn 2 by 2</u></em>
8x + 8y = -8 ------ eqn 3
<em><u>Add eqn 1 and eqn 3</u></em>
-8x + 2y = -2
8x + 8y = -8
( + ) ---------------
0x + 2y + 8y = -2 - 8
10y = -10
Divide both sides by 10
y = -1
<em><u>Substitute y = -1 in eqn 1</u></em>
-8x + 2(-1) = -2
-8x - 2 = -2
-8x = -2 + 2
x = 0
Thus the solution to system is x = 0 and y = -1
