Answers

Answer:

5x + 3y = 95

8x + 6y = 170

x = 10 ; y = 15

Step-by-step explanation:

Let :

x = pack of juice boxes

y = pack of water bottles

Pack of juice box = $5

Pack of water bottles = $3

Amount of money spent :

5x + 3y = $95

Number of drinks purchased :

8x + 6y = 170

Using both equations ;

5x + 3y = 95 - - - (1)

8x + 6y = 170 - - - (2)

Multiply (1) by 6 and (2) by 3

30x + 18y = 570

24x + 18y = 510

Subtract :

6x = 60

x = 60 / 6

x = 10

Put x = 10 in (1)

5(10) + 3y = 95

50 + 3y = 95

3y = 95 - 50

3y = 45

y = 45 / 3

y = 15

x = 10 ; y = 15

What is trigonometry?

The branch of mathematics that sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry. The trigonometric functions, also known as a circular, angle, or goniometric functions in mathematics, are real functions that link the angle of a right-angled triangle to the ratios of its two side lengths.

Given that in ΔPQR, p = 8.5 cm, q = 1.7 cm and r=7.7 cm. The value of angle ∠r will be calculated as,

r² = p² + q² -2pqcos(r)

(7.7)² = (8.5)² + (1.7)² - 2 x 8.5 x 1.7cos(r)

59.29 -75.14 = -28.9cos(r)

cos(r) = 15.85 / 28.9

cos(r) = 0.55

r = cos⁻¹(0.55)

r = 56.63°

I know life can get hard but don't give up no matter what happens, because you never get anything out of quitting, but you get the most if you keep trying, and trying.

This is what you don't do

Don't let this world make you bitter. Don't let the actions of other people turn you cold on the inside. Certain things happen that hurt us, people come that leave us, and most of all there are moments when you're bound to fall. Don't let those things make you unkind. It's okay to cry. It's okay to be sad. But it's never okay to do other people wrong just because you were done wrong. We're human. We break. We make mistakes. But don't let pain and sadness run your lives. Wake up in the morning and do what you think is right. There are moments in your life where you feel like giving up and you can't take it anymore. It's okay. Breathe. Inhale. Exhale. I know you're weak. But the things that show your weak side are also the same ones that make you stronger in the long run. It's all about taking whatever life throws at you and learning from it.

Hope you like it. Have a great day.​

x = 6

Step-by-step explanation:

Step 1: Cross multiply.

[tex]\frac{x}{2x+4} = \frac{3}{8} \\x*(8)=3*(2x+4)\\8x=6x+12[/tex]

Step 2: Subtract 6x from both sides.

[tex]8x-6x=6x+12-6x\\2x=12[/tex]

Step 3: Divide both sides by 2.

[tex]\frac{2x}{2} =\frac{12}{2}[/tex]

Answer:
x=6

Solution:
X/(2x+4) = 3/8

1) Cross -multiply
X * (8) = 3 * (2x+4)
8x = 6x + 12

2) Subtract 6x from both sides
8x - 6x = 6x + 12 - 6x
2x = 12
12/2 = 6

X= 6

Answer:

The slope is -10.

Step-by-step explanation:

Goal

Find the value of m/Find the slope.

Given

Two coordinate points which are (-1,7) and (0,-3).

Step 1

Use the slope formula which is rise over run also known as changes of y over changes of x.

[tex] \large \boxed{m = \frac{y_2-y_1}{x_2-x_1} }[/tex]

From the given coordinate points, substitute the values in the formula.

[tex]m = \frac{7 - ( - 3)}{ - 1 - 0} \\ m = \frac{7 + 3}{ - 1} \longrightarrow \frac{10}{ -1} \\ m = - 10[/tex]

Therefore, the value of m or slope is -10.
