We want to solve the following system of equations using the substitution method.
Equation 1- 4p+7q=92/5
Equation 2- 12p+35q=72
Solve for q

Answers

Ok, so you are given the value of P=q+2

The substitution method tells us that we must insert the value we know, into the second equation, 4P+3q= -27

Doing so will give us 4(q+2)+3q= -27

For right now, lets just focus on the first part, 4(q+2)

We can simplify this by distributing(multiplying) the 4 to whats inside the variables.

This will give us 4q+8

now lets add this back to the rest of the equation >>>  4q+8+3q = -27

We can further simplify by adding like terms >>> 7q+8 = -27

subtract the 8 from both sides >>> 7q = -35

now divide both sides by 7 >>> q = -35/7

Therefor q = -5

EDIT*

now that we know q = -5 we can put q into the equation for P !

we know that p=q+2

so lets put q in now >>> p=(-5)+2

and simplify>>> p = -3

I hope this helps:)

It’s -5 when you do the math

Step-by-step explanation:

area = base × height / 2

22.68 = base × 5.6 / 2

Multiply both sides by 2.

45.36 = base × 5.6

Divide both sides by 5.6.

8.1 = base

What are the slope and the y-intercept of the linear function that is represented by the graph?

On a coordinate plane, a line goes through points (0, negative 2) and (3, 0).

Answers

Answer:

slope=2/3

y-intercept -2

y=2/3x-2

Step-by-step explanation: You have to do y-y divided by x-x, so 0 mins-2 which equals 2 and 3-0 which equals 3, and then you get 2/3. For the y-intercept, you have to plug in one of the points into x any y so your equation will be -2=2/3(0)+b and then you have to multiply 2/3 and 0 and you get 0 so your equation is -2=0+b and finally, you have to subtract -2-0 which equals -2 and your y-intercept is b=-2.

2/3, -2

please help DUE TODAY

Answers

Answer: (Decreasing Order) 170, 13 7/8, 13.5, 64/5

Step-by-step explanation:

Sqrt 170 = 13.038

Sqrt 13.5 = 3.674

Sqrt 64/5 = 12.8 = 3.577

Sqrt 13 7/8 = 13.875 = 3.724

The values in decreasing order are- 13.5 > 13 > 64/5 > square root 170 > 7/8

What is decending order?

A series arranged that begins with the greatest or largest and ends with the least or smallest is called as descending order.

The given numbers are,

square root 170, 13.5, 64/5, 13 7/8

Before comparing, we need to write all of those numbers in decimal form.

So, converting all the numbers in decimal for,

square root 170 = √70 = 8.336

13.5

64/5 = 12.8

13

7/8 = 0.875

Hence arranging them from highest to lowest,

13.5 > 13 > 12.8 > 8.336 > 0.875

Thus, the decreasing order of original numbers are,

13.5 > 13 > 64/5 > square root 170 > 7/8
