Answer:

The value of x and y is -2 and 3

step by step explaination:

7x + 3y = -5 be equation 1st and x + y =5 be equation 2nd and multiply equation 2nd by 3 then subtract it .

then we get,

7x + 3y = -5

3x + 3 y= 3

(-). (-). (-)

_________

4x. = -8

x =. - 8/4

x = -2

substitute the value of x in equation in 1

7x +3y = -5

7* (-2) + 3y = -5

-14 + 3y = -5

3y = 14-5

y =9/3

y=3

HELP!!! A cell phone is 132 mm long and 57 mm wide. What is ratio of the width and length in simplest form.
GalinKa [24]

The ratio of width to length in simplest form is 19 : 44

<em><u>Solution:</u></em>

Given that, A cell phone is 132 mm long and 57 mm wide

Length of cell phone = 132 mm

Width of cell phone = 57 mm

We have to find the ratio of width and length in simplest form

\frac{Width}{Length} = \frac{57}{132}\\\\\text{Reduce to lowest terms }\\\\\frac{width}{length} = \frac{57 \div 3}{132 \div 3}\\\\\frac{Width}{Length} = \frac{19}{44}

In ratio form, we know that,

\frac{a}{b} = a : b

Writing in ratio form, we get

Width : length = 19 : 44

Thus the ratio of width to length in simplest form is 19 : 44

Resident always seems to have a dirty truck his girlfriend gave him a gift card to car wash after three carwashes rest at 61.75
Llana [10]
I’m thinking it’s $100. I guessed 100 first as that is a pretty common number and subtracted 61.75. I was left with 38.25 and I divided that by 3, the amount of washes. I got $12.75 but I had to check since I guessed 100. I then subtracted 23.50 from 100 and got 76.5. I divided that by 6, the amount of washes, and got 12.75 again. So I’m pretty sure that there was $100 on the gift card before he washes his car six times, each wash being $12.75.
