Solve the following systems using the elimination method.

4x + 7y = 19
2x - y = -13

Answers

Answer: x = -4, y = 5

Step-by-step explanation:

[tex]$$Solve the following system: \\$\left\{\begin{array}{ll}7 y+4 x=19 & \text { (equation 1) } \\ -y+2 x=-13\end{array} \quad\right.$ (equation 2)\\\\Subtract $\frac{1}{2} \times($ equation 1) from equation 2 :\\$\left\{\begin{array}{l}4 x+7 y=19 \ \ \ \ (\text{equation 1}) \\ 0 x-\frac{9 y}{2}=-\frac{45}{2}\end{array}\right.$ (equation 2)\\\\Multiply equation 2 by $-\frac{2}{9}$ :\\[/tex]

[tex]\begin{cases}4 x+7 y=19 & \text { (equation 1) } \\ 0 x+y=5 & \text { (equation 2) }\end{cases}$\\\\Subtract $7 \times($ equation 2) from equation 1:\\$\begin{cases}4 x+0 y=-16 & \text { (equation 1) } \\ 0 x+y=5 & \text { (equation 2)\\ }\end{cases}$\\\\Divide equation 1 by 4 :\\$\begin{cases}x+0 y=-4 & \text { (equation 1) } \\ 0 x+y=5 & \text { (equation 2) }\end{cases}$\\\\Answer:\\$$\left\{\begin{array}{l}x=-4 \\y=5\end{array}\right.$$[/tex]

Answer: x = -4, y = 5

Step-by-Step Explanation:

=> 4x + 7y = 19 (Eq. 1)
=> 2x - y = -13 (Eq. 2)

We can multiply Eq. 2 by 7 in order to make the coefficients of ‘y’ same in both the equations thus being able to eliminate ‘y’ and find ‘x’

Therefore,
(2x - y = -13) * 7
=> 14x - 7y = -91 (Eq. 3)

On Adding Eq. 1 and 3, we get :-

18x = -72 (‘y’ gets Eliminated)
x = -72/18
=> x = -4

Therefore, x = -4

Substitute value of ‘x’ in Eq. 2 :-

2x - y = -13
2(-4) - y = -13
-8 - y = -13
-y = -13 + 8
-y = -5
=> y = 5

Therefore, y = 5

i didnt mean to click on the 31.50 but what is the answer ?

Answers

Answer:

D. $67.50

Step-by-step explanation:

A ticket costs $5.25, a drink costs $2.00, and a popcorn costs 4.00. Each person in the group buys all of these. So we know that each person is paying:

4.00 + 2.00 + 5.25 = 11.25

Since there are 6 people in the group we can multiply that by 6:

11.25 * 6 = 67.50

If you add all of them together you get 11.25
Then times it by 6 and that’s 67.5 then add the zero and that gets you 67.50 and that’s your answer

Consider the figure.
Find the area of the composite figure to the nearest half unit. Use 3.14 for π

Answers

Answer:

23.5 cm^2

Step-by-step explanation:

First calculate the "rectangle" with the half-circle filled in

9*3 = 27

Then calculate the half-circle using the formula for the area of a circle [tex]\pi r^{2}[/tex], then dividing it by half

3.14 * 1.5 * 1.5 / 2 = 3.5325

Subtract the area of the half-circle from the area of the rectangle

27-3.5325

= 23.4675

= 23.5 (cor. to the nearest half unit)

The answer is 23.5 cm squared

J and G dont equal -8                                                                                      

Not H because two negatives equal positive                                                    

F works because if you do it without the negative, it’s eight.                    

Since there is only one negative it turns negative. (-8)

Answers

Answer:

1.8 gallons

Step-by-step explanation:

5.2 x 3 = 15.6

2.3 x 6 = 13.8

15.6 - 13.8 = 1.8

Answer:

1.8 Gallons

Step-by-step explanation:

Devin: 5.2x3= 15.6

Linda: 2.3x6=13.8

15.6-13.8= 1.8 Gallons

1/10x+9/10=1/10(BLANK)

Answers

Answer:

x=-8

Step-by-step explanation:

1 Simplify 1/10x to x/10.

x/10 + 9/10 = 1/10

2 Join the denominators.

x+9/10 = 1/10

3 Multiply both sides by 10.

x+9 = 1/10×10

4 Cancel 10.

x+9=1

5 Subtract 9 from both sides.

x=1-9

6 Simplify  1-9 to  -8.

x=-8
