What is the solution to the system of equations?

Mathematics
1 answer:
Jlenok [28]3 years ago
4 0

Answer:

The solution would be (-19, 40)

Step-by-step explanation:

In order to solve this system by substitution, simply take the value of y in the first equation and use it in place of y in the second. This will allow you to solve for x.

5x + 2y = 15

5x + 2(-3x - 2) = 15

5x - 6x - 4 = 15

-x - 4 = 15

-x = 19

x = -19

Now that we have the value of x, we can find the value of y.

y = -3x - 3

y = -3(-19) - 3

y = 43 - 3

y = 40

AleksAgata [21]

Answer:

Equation: 10+x= 15 +0.5x

Time: 10 days

Amount: 20$

Step-by-step explanation:

<u>Equation for Benito:</u>

  • 10 + x*1

<u>Equation for Tavon:</u>

  • 15 + x*0.5

<u>Since the sums equalize at some time, we get:</u>

  • 10+x= 15 +0.5x
  • x - 05x = 15- 10
  • 0.5x = 5
  • x= 5/0.5
  • x= 10 days

After 10 days, Juan will owe both Benito and Tavon $20

the base of the founten is rectangular . its dimention 1 2/3 feet by 2 2/3 feet . what is the area of the base of the founten
Montano1993 [528]
The area of a rectangle is calculated by multiplying the length of the rectangle and the width of the rectangle. In this case, the length (the longer side) is 2 2/3 feet while the width (shorter side) is 1 2/3 feet. To multiply fraction, first convert mixed numbers into improper fractions:

2 2/3 = 8/3
1 2/3 = 5/3
Multiplying the two fractions yield: 
8/3 x 5/3 = 40/9 ft2 

The final answer is 40/9 ft2 or 4 4/9 ft2.
