In parallelogram defg,, DH = x+3 HF= 3y GH=3x-3 and HE =5y + 4

olasank [31]

<u>Answer:</u>

The value of x and y is 9 and 4 units

<u>Solution: </u>

We have,

DH = x+3; HF= 3y and GH=3x-3; HE =5y + 4

For parallelogram, we know that,

DH=HF

So, $(x+3)=3 y\Rightarrow x=(3 y-3)$ --------- (i)

Again, GH = HE

So, $3x-3 = 5y +4$

$\Rightarrow3 x=5 y+4+3$

$x = \frac{(5y+7)}{3}$ ………. (ii)

Now equating both (i) and (ii) we get,

$\Rightarrow3 y-3=\frac{5 y+7}{3}$

$\Rightarrow3\times(3y-3) = 5y+7$

$\Rightarrow9y - 9 = 5y +7$

$\Rightarrow9y-5y=7+9$

$\Rightarrow4y = 16$

$\Rightarrow y = 4$

So the value of $x = 3\times4 -3 = 9$

The value of x and y is 9 and 4 units

at Alan's sports shop, GO FAST trainers cost £40.95 originally and there is a third off in the sale. At Irene's sport shop, GO

dem82 [27]

The trainers will be cheaper at Alan's sport shop.

prices ->
Alan's: 27.30
Irene's: 28.00

$\frac{1}{3}$ of 40.95 can be calculated as follows ->

$\frac{1}{3}$ = $\frac{x}{40.95}$
simplify to get that x = 27.30

30% of 40.00 can be calculated as follows ->

$\frac{30}{100}$ = $\frac{x}{40.00}$
simplify to get that x = 28
