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

Thank you so much!
Answers
Answer:
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]
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

Let's solve your system by substitution.
y=2x+1;y=4x−1
Step: Solve y=2x+1for y:
y=2x+1
Step: Substitute2x+1foryiny=4x−1:
y=4x−1
2x+1=4x−1
2x+1+−4x=4x−1+−4x(Add -4x to both sides)

−2x+1+−1=−1+−1(Add -1 to both sides)
−2x=−2

[tex]\frac{3x + 5}{4x +2}=\frac{3x+4}{4x + 7}[/tex]
Cross multiply,
(3x+ 5 ) (4x + 7)=(3x + 4)*(4x + 2)
3x*4x + 3x *7 + 5*4x + 5*7 = 3x*4x + 3x*2 +4*4x + 4*2
12x² + 21x + 20x + 35 = 12x² + 6x + 16x + 8 {Combine like terms}
12x² + 41x + 35 = 12x² + 22x + 8
12x² + 41x +35 - 12x² - 22x = 8
12x² - 12x² + 41x - 22x + 35 = 8
0 + 19x + 35 = 8
19x = 8 - 35
19x = -27
x = -27/19

m=(y2-y1)/(x2-x1)
m=(-3-7)/(0-(-1))
m=-10/(0+1)
m=-10/1
m=-10
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.

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°

2. You are able to distribute -5, and you get -5x when it goes into x, and you get positive 10 because it is a negative times a negative. So the answer would be B, -5x + 10
3. On this type of problem, when there is a negative in the middle, you MUST turn it positive. This means you distribute the negative, and everything on the right of the minus sign changes to negative or positive. So it would change to -
(8x-6)+(x-4)
When you add, you get 9x-10, which is C.
4. Simply just add these two, which is what we got to on the last problem, and you get 20x-6, which is choice A.
5. For this, you substitute the numbers in the equation. So it would be -
2(5)-4(-1)
This would equal 14, which is A.
6. You substitute 4 for x, so it would be -
4^2 + 5
4 • 4 + 5
16 + 5
21, Choice B
7. When you combine like terms here, the 3y’s cancel out because they equal each other, so the answer would just be 19, which is A.
The answers for the given Expression are;
1) 15(x+2)
2) -5x + 10
3) 9x - 10
4) 20x - 6
5) 14
6) 21

What is an Expression?Numbers, symbols and operators (such as and times) grouped together that show the value of something.
Given are the Expressions to solve;
1) 15x + 30
GCF for this Expression is 15 therefore
15x + 30 = 15(x+2)
2) -5(x - 2) = -5 + 10
3) (8x - 6) - (-x + 4) = 8x - 6 + x - 4 = 9x - 10
4) (11x - 2) + (9x - 4) = 20x - 6
5) 2x - 4y when x = 5 and y = -1
2x - 4y = 2*5 - 4*(-1) = 14
6) x² + 5 when x = 4
4² +5 = 16 + 5 = 21
7) -3y + 12 + 3y + 7 = 19
Hence, The Answers are :
1) 15(x+2)
2) -5x + 10
3) 9x - 10
4) 20x - 6
5) 14
6) 21

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.
