5×=15+10y,3×+7y=31 it's for tomorrow pls

Katarina [22]

Answer:

x = 6.39, y = 1.69 is the solution of the given equation system.

Step-by-step explanation:

Here, the given set of equation is:

5 x = 15 + 10 y ⇒ 5 x - 10 y = 15 ...... (1)

3 x +7 y = 31 ............. (2)

Now, the coefficient of x in first equation id 5 and in second is 3.

So, MULTIPLY (1) with 3 and (2) with -5 , we get:

15 x - 30 y = 45

-15 x- 35 y = -155

<u>ADD BOTH EQUATIONS ,</u> we get:

15 x - 30 y -15 x- 35 y = 45 - 155

or, -65 y = -110

or, y = 110/65 = 1.69

Put y = 1.69 in 3 x +7 y = 31 , we get:

3(x) + 7 (1.69) =31

⇒ 3 x = 19.17 or x = 6.39

Hence, x = 6.39, y = 1.69 is the solution of the given equation system

Cal's go cart has a gas tank with the dimensions shown below. He uses a gas can that holds 11 gallon of gas, to fill the go cart

RSB [31]

Answer:

This question is incomplete as no image was attached. Please find the missing image in the attachment. Also, this is the correct question:

Cal's go cart has a gas tank with the dimensions shown below. He uses a gas can that holds 1 gallon of gas, to fill the go cart tank. 1 gallon = 231 inches^3. How many full gas cans will it take to fill the go cart's gas tank?

Answer: 2 full gas cans

Step-by-step explanation:

From the image, we have the following dimensions:

length, l = 15.4 inches (in)

width, w = 10 in

height, h = 3 in.

The volume of the gas tank (which is rectangular) is given as:

$Volume = length * width * height = lwh\\\\Volume = 15.4 * 10 * 3 = 462 cubic inches = 462in^{3}$
