2x+2y= 24 x=3y What is the value of x+y? I WILL MARK BRAINLIEST AND GIVE 20 POINTS.

1 answer:

3 0

Since this is a system of equations, substitute the value of x into the other equation.

2(3y)+2y=24
6y+2y=24
8y=24
y=3

x=3(3)
x=9

To check my work, substitute my x and y values:
2(9)+2(3)=24
18+6=24
24=24

Your answer is (3,9)

Hope this helps! Have a wonderful day :)

The perimeter of a rectangular flower garden is 66m and its area is 272m^2. Find the length of the garden.

ExtremeBDS [4]

So we have lengths a and b and are given:

2a+2b = 66 => a+b = 33 => a= 33-b
a*b = 272

plug in one into the other:

(33-b)b = 272 => -b^2 +33b - 272 = 0

Can be factored as (b-16)(b-17) = 0, if you don't "see" this immediately, use the well known abc formula to find b.

So a=16 and b=17 or vice versa.

Zolol [24]

Answer:

Percentage increase in volume will be

33.1

Step-by-step explanation:

Let the each edge of cube be

100

units.

Then its volume is

100

1000000

cubic units.

If each edge increases by

it becomes

110

units

and volume becomes

110

1331000

cubic units

Therefore increase in volume is

1331000

−

1000000

331000

cubic units

and percentage increase in volume is

331000

When a jar of fruit is 2/3 of the way full it can hold 2 1/4 cups of fruit what fraction of the jar is full when it only contain

Natali [406]

Answer:

8/27

Step-by-step explanation:

<h2><u>Fractions</u></h2>

a jar of fruit is 2/3 of the way full it can hold 2 1/4 cups of fruit

what fraction of the jar is full when it only contains one cup of fruit?

by using these statements , we can solve this through <u>cross multiplication</u>:

fraction that the jar is full : number of cups of fruit

$\frac{2}{3}$ : $2 \frac{1}{4}$

x : 1

$\frac{2}{3} = 2 \frac{1}{4} x$

convert $2 \frac{1}{4}$ from a mixed fraction to an improper fraction

hence 2 1/4 = 9/4

solve

$\frac{2}{3} = \frac{9}{4} x$ .

x = $\frac{2}{3} / \frac{9}{4}$

<h3><u>when the cup contains one cup of fruit its fraction 8/27 full </u></h3>
