1. Identify the graph that represents the system of
linear equations

Answer:

Yes.

Step-by-step explanation:

2/3 and 8/12 are equal because of a multiplying factor. To get from 2 to 8, you'd have to multiply by 4. And to get from 3 to 12 you would have to multiply by 4 as well. So that means they are equal because both the numerator and denominator are multiplied by 4.

If two ratios are equal then the ratios are said to be in proportion and equivalent.

The ratios 2/3 and 8/12 are equivalent.

The simplest form of both ratios is 2/3.

The ratio is the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

If two ratios are equal then the ratios are said to be in proportion and the ratios are said to be equivalent.

We have,

Two ratios:

2/3 and 8/12

We will make the ratios in their simplest form:

2/3 is in the simplest form.

8/12 = 4x2/4x3 = 2/3 is the simplest form.

We see that both the ratios are equal so the ratios 2/3 and 8/12 are in proportion.

Thus,

The ratios 2/3 and 8/12 are equivalent.

The simplest form of both ratios is 2/3.

Answer:

G=-2t=12

Step-by-step explanation:

uh well i did delta thats was the answer they gave me...

Total capacity: 12 gallons

Equation: G = 12 - R*t

What is mathematical expression?

A mathematical expression is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Let R be rate of gas consumption by car = 2 gallons/hr

Let G be the gallons in the car left

let g be the gallons used by the car while driving

Driven time, t = 4 hrs

Remaining gas =4 gallons

according to the question,

consumption rate, R = g/t

After driving for 4 hours

2 = g/4

g = 2*4 = 8 gallons

remaining gas = 4 gallons

therefore, total capacity of the car = 8 + 4 = 12 gallons

equation in terms of gas left,

G = 12 - R*t

Answer:

4860000

Step-by-step explanation:

just multiple the interest by monthly payment and then by 30

Let the digit in one's place be y and digit at ten's place be x.

Sum of the digits = 11

⟶ x + y = 11

⟶ x = 11 - y -- equation (1).

And,

The number formed by reversing the digits is 27 more than the original number.

⟶ Reversed number = Original number + 27

reversed number = 10y + x.

⟶ 10y + x = 10x + y + 27

⟶ 10y + x - 10x - y = 27

⟶ 9y - 9x = 27

Substitute the value x from equation (1).

⟶ 9y - 9(11 - y) = 27

⟶ 9y - 99 + 9y = 27

⟶ 18y = 27 + 99

⟶ 18y = 126

⟶ y = 126/18

⟶ y = 7

Substitute the value of y in equation (1).

⟶ x = 11 - 7

⟶ x = 4

The number = 10(4) + 7 = 40 + 7 = 47.

∴ The required two digit number is 47.

Step-by-step explanation:

Answer:

m = 1.35

Step-by-step explanation:

Buzz = m

Maria = m + 2.4

Together = 5.1

Equation:

m + m + 2.4 = 5.1

2m + 2.4 = 5.1

2m = 2.7

m = 1.35

So now:

Buzz = 1.35

Maria = 1.35 + 2.4 = 3.75

1.35 + 3.75 = 5.1

This solution is correct.

Answer:

la respuesta correcta es $123.222per mile

Answer: T he number of miles in a day at which the rental costs for Company A and Company B are the same is when x = 160miles.

Step-by-step explanation:

Step 1

Let us  write the rental cost with each company:

Company A , they will charge =$160 +$ 0.40x

Company B, They will charge = $80 + $0.90x

Where x =number of miles travelled

Step 2

we then find the number of miles in a day at which the rental costs for Company A and Company B will be  the same by equating both equations and solving for x

160 + 0.40x= 80 + 0.90x

160-80 = 0.90x-0.40x

80= 0.50x

x= 80/0.5

x= 160

Therefore t he number of miles in a day at which the rental costs for Company A and Company B are the same is when x = 160 miles.

Answer: $88.

Step-by-step explanation:

given data:

The cost of the dress for the prom = $22

label of the rack the dresss was on = 50%.

lowest marked price for the dress = 75%.

Solution:

if the lowest marked price of the cloth was already 75%.

and the current cost of the clothe is $22

the original cost of the cloth would be

100% – 75% = 0.25%

= $22 * 100 / 0.25%

= $88.

The original cost of the dress was $88

Answer:

Step-by-step explanation:

Since it's a right angled triangle we can use trigonometric ratios to find the value of x

To find the value of x we can use either sine or cosine

[tex] \sin(30) = \frac{5}{x} \\ x \sin(30) = 5 \\ x = \frac{5}{ \sin(30) } \\ x = \frac{5}{0.5} \\ \\ \\ \boxed{x = 10}[/tex]

[tex] \cos(60) = \frac{5}{x} \\ x \cos(60) = 5 \\ x = \frac{5}{ \cos(60) } \\ x = \frac{5}{0.5} \\ \\ \\ \boxed{x = 10}[/tex]

Answer:

[tex]y = - 2x + 5[/tex]

Step-by-step explanation:

Simply simplify the equation from what it is to the slope intercept format:

[tex]y = mx + b[/tex]

Step-by-step explanation:

Hey there!

We know;

The slope intercept form of equation is;

y = mx+c

So, let's try to take it in this form.

(y-1) = -2(x-2)

Multiply -2 and (x-2)

(y-1) = -2x + 4

Take '-1' to right side.

y = -2x+4+1

y = -2x+5

Therefore, the equation is y = -2x+5.
