WILL GIVE BRAINLIEST. If x+y=3 and 3x+5y=13, then x-y is equal to?
Alex17521 [72]

Answer:

(1,2)

y=2

x=1

Step-by-step explanation:

x+y=3

3x+5y=13

solve the equation

x=3-y

3x+5y=13

substitute the value of x into an equation

3(3-y)+5y=13

distribute

9-3y+5y=13

add -3y to 5y

9+2y=13

subtract 9 from both sides

2y=4

divide both sides by 2

y=2

substitute the value of y into an equation

x=3-2

subtract 3 to 2

x=1

--------

(1,2)

Mutiple choice pls help !!
Vedmedyk [2.9K]

Answer:

5π m

Step-by-step explanation:

Using the pythagorean theorem we can figure out that the third side is 5m

A^2 + B^2 = C^2

3^2 + 4^2 = C^2

9 + 16 = C^2

25 = C^2

√23 = √(C^2)

C = 5m

Side C is also the diameter of the circle, so the radius is 5/2, or 2.5

From that we can use the circumference formula, Circumference = 2π<em>r</em>

Circumference = 2 π (2.5) = <u>5π m</u>

(HURRY) Janet is mixing a 15% glucose solution with a 35% glucose solution. This mixture produces 35 liters of a 19% glucose sol
Arturiano [62]

Answer:

c. 28 liters

Step-by-step explanation:

Given tha tJanet is mixing a 15% glucose solution with a 35% glucose solution. This mixture produces 35 liters of a 19% glucose solution. Now we need to find about how many liters of the 15% solution is Januet using in the mixture.

Let the number of liters of the 15% solution is Januet using in the mixture = x

Let the number of liters of the 35% solution is Januet using in the mixture = y

Then we get equations:

x+y=35...(i)

and

(15% of x) + (35% of y) = 19% of 35.

or

0.15x+0.35y=0.19(35)

15x+35y=19(35)

3x+7y=19(7)

3x+7y=133 ...(ii)

solve (i) for x

x+y=35

x=35-y...(iii)

Plug (iii) into (ii)

3x+7y=133

3(35-y)+7y=133

105-3y+7y=133

105+4y=133

4y=133-105

4y=28

y=28/4

y=7

plug y=7 into (iii)

x=35-y=35-7=28

Hence final answer is c. 28 liters
