The numbers are 7 and 10 if the sum of two positive integers is 17 and the smaller integer is subtracted from five times the larger, the result is 43.

<h3>What is a linear equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

Set up a linear system and solve. The sum of two positive integers is 17.

When the smaller integer is subtracted from five times the larger, the result is 43.

Let the numbers x and y:

x + y = 17

5y - x = 43  ( let x < y)

Solving the above two linear equations in two variables:

x = 17 - y

5y - (17 - y) = 43

5y - 17 + y = 43

6y = 60

y = 10

x = 17 - 10 = 7

Thus, the numbers are 7 and 10 if the sum of two positive integers is 17 and the smaller integer is subtracted from five times the larger, the result is 43.

Find the surface area of each figure. Round to the nearest hundredth when necessary Please quick and real answers

The total surface area of the cone is 542.592 square mm

<h3>Total surface area of a cone</h3>

The formula for calculating the total surface area of a cone is expressed as:

TSA = πr(r + l)

where

r is the radius of the cone

l is the slant of the cone

Given the following parameter

l = 13.6mm

r = 8mm

Substitute

TSA = π(8)(8+13.6)
TSA = 3.14(8)(21.6)

TSA = 542.592 square mm

Hence the total surface area of the cone is 542.592 square mm

Mila [183]

Answer:

<em>(-3/5, 29/5) </em>

Step-by-step explanation:

Given the simultaneous equation;

-3x+4y=25...... 1

y= -3x+4 ..... 2

We are to confirm if (-3, 4) is the solution to the equations;

Substitute equation 2 into 1;

From 1;

-3x+4y=25

-3x + 4(-3x+4) = 25

-3x -12x + 16 = 25

-15x = 25 - 16

-15x = 9

x = -9/15

x = -3/5

Substitute x = -3/5 into equation 2 to get y;

From 2;

y= -3x+4

y = -3(-3/5)+4

y = 9/5 + 4

Find the LCM

y = (9+20)/5

y = 29/5

<em>Hence the solution to the system of equation is (-3/5, 29/5) hereby falsifying Julie's solution.</em>

What is the average of 32 and 13​
Mila [183]

Answer: I think the answer is 22.5

Step-by-step explanation:

32 + 13 = 45

45/2 = 22.5

First you would add the two sums together then depending on how many you are adding ( like 2 because there are 2 numbers there) you would divide by that number.
