Answer:
Solution set = {25}
Step-by-step explanation:
=>
Dividing both sides by -1
=>
Taking square on both sides
=> x = 25
<em><u>Solution set = {25}</u></em>
The answer would be <u>16</u>. Neither 24, 28, or 36 can multiply by a whole number to equal 64, and 16 cannot be multiplied by a whole number to equal those values.

Answer:
the answer is 6
Step-by-step explanation:
3×2-0×2=6
Answer:
(5, - 6 )
Step-by-step explanation:
Given the 2 equations
- 8x - 10y = 20 → (1)
- 8x - 6y = - 4 → (2)
Multiply (2) by - 1
8x + 6y = 4 → (3)
Add (1) and (3) term by term to eliminate the x- term, that is
- 4y = 24 ( divide both sides by - 4 )
y = - 6
Substitute y = - 6 into either of the 2 equations and solve for x
Substituting into (1)
- 8x - 10(- 6) = 20
- 8x + 60 = 20 ( subtract 60 from both sides )
- 8x = - 40 ( divide both sides by - 8 )
x = 5
solution is (5, - 6 )
To get this answer you must first get the VAT cost which we will get with the following steps.
First make the percent a decimal to do so move the . over to the left two times
Resulting in .20 now multiply it with 800
800(.20)=160
Now add 160 to 800
800+160=960
So the total cost for this TV is £960
