It would be the same, as it is 60% both times. For example, you add 5 to 0. Its 5. Then if you take away 5, it will be 0 again, the beginning number.

It would go back to the same price because if it jumped up 60% and then back down 60%, since it is the same amount, it would be like you didn't even increase the price, unlike if it jumped 65% and then down 60%.

$7.9 cost of one pack
10 packs cost is $79
She pays $29 + Voucher

From the total $79 we substract the $29 she paid with cash or card.

Check my answer please
Aleksandr [31]
So it is an isosceles triangle that means that the bottom two angles are equal...
so 
40 = 5x 
divide both sides by 5 and you get 8

now the triangle angles add up to 180
we make an equation out of it...
(2y + 20 ) + ( 5(8)) + 40 = 180
2y + 20 + 40 + 40 = 180
combine like terms
2y + 100 = 180
so subtract 100 from both sides
2y = 80
divide by 2 to isolate the variable
y = 40

You are correct!!! :)

Y=4x<br> x+y=5<br><br> Help me get the answer
Ugo [173]
To solve this first we need to get are chunk which is already solved for here as
Y=(4x) so one the chunk side of this we dont have to solve for it, so now we can just skip right to solving this equation like so. First input the numbers x+(4x)=5,
Distribute/Combine like terms in this case
5x=5
Divide by 5
x=1
So now that we have x we can plug it into are chunk and then we have are answer
Y=(4x)
Y=(4*1)
Y=4
So are end answers are \left \{ {{y=4} \atop {x=1}} \right.
Enjoy!=)

What is the value of X in the triangle attached?
Juliette [100K]

Answer:

X = 22°

Step-by-step explanation:

Accordng to Exterior Angle Sum Property , measure of an exterior angle is equal to the sum of the 2 interior opposite angles.

So,

(2x) + (103 - x) = 6x - 7

=  > x + 103 = 6x - 7

=  > 6x - x = 103 + 7

=  > 5x = 110

=  > x =  \frac{110}{5}  = 22

Given that the measure of ∠x is 60°, and the measure of ∠y is 90°, find the measure of ∠z.
UkoKoshka [18]
The answer is 30 because u need to add 60+90=150 and then subtract 180-150 which gives you 30
