Work out the value of 4y+3x when x=5 and y=-3

Thanks

Answers

Answer 1

Hey there!

“4y + 3x”

If x = 5 and y = -3, then substitute it into the equation

4(-3) + 3(5)

4(-3) = -12

-12 + 3(5)

3(5) = 15

-12 + 15

= 3

Answer: 3

Good luck on your assignment and enjoy your day!

1. Find the slant height of a square pyramid with a surface area of 57 square feet and a base perimeter of 12 feet

Answers

Answer:

Slant height = 8 feet.

Step-by-step explanation:

If the perimeter of the square base = 12 then each side of the base = 12/4

= 3  feet and its area = 3*3 = 9 ft^2

The area of one of the triangular sides = 1/2 * 3 * h where h is slant height.

So total surface area = 57 = 9 + 4 * 1.5h

9 + 6h = 57

6h = 48

h = 8 feet.

Find the median for the number of pencils.

Answers

Answer:

The median is 2

Step-by-step explanation:

Here, we want to get the median for the number of pencils

Firstly, we have to write out the numbers that form the box plot ; we have this as;

1,1,1,2,2,2,2,3,3,5

the median is sum of the 5th and 6th term divided by 2

The 5th term is 2

The 6th term is 2

So the median is;

(2 + 2)/2

= 4/2 = 2

What is the area of the shaded portion of the trapezoid in the figure, in terms of? The figure is not drawn to scale. All of the given measurements are in feet.

Answers

Answer:

(150-36π) ft^2

Step-by-step explanation:

we need to subtract the area of the circle from the area of the trapezoid to find the area of the shaded region.

area of circle=πr^2=π6^2=36π ft^2

area of trapezoid=(1/2)(a+b)h=(1/2)(12+13)12=150 ft^2

so, the area of trapezoid-area of circle=(150-36π) ft^2

Roy hit 3 less than 4 times the number of balls during baseball practice than Joe did. Together the boys hit 52 balls. How many balls did Joe hit?

Answers

Make a equation
Joe = x
Roy = 4x - 3
They add up to 52 balls
x + 4x - 3 = 52
5x - 3 = 52
5x = 55, x = 11
Since Joe is x, he hit 11 balls

Answer:

Joe hit 11 balls       Roy hit 41

Step-by-step explanation

Joe = J

Roy = 4J-3 (4times Joe  less 3)

J+ 4J-3 = 52

5J -3 = 52

Add 3 on both sides  

5J = 55

Divide both sides by 5

J= 11

Joe = 11

11X4 = 44

44-3 = 41

Roy 41

11+41 = 52

Awad claims that when m is a negative integer and n is a positive integer, n - m is always negative. Is Awad’s claim true or false? Explain your reasoning. If it is true, give an example to support his claim. If it is false, give a counterexample. Explain your reasoning..

Answers

Answer:

False

Step-by-step explanation:

False, because whenever you subtract a negative number, you always end up adding because two negatives make a positive. Lets say n is 4 and m is -3, 4-(-3) is going to turn into 4+3=7.

The Awad'claims that "when m is a negative integer and n is a positive integer, n - m is always negative". which is false.

What is the number system?

A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9. Based on the basic value of its digits, different types of number systems exist.

Awad claims that when m is a negative integer and n is a positive integer, n - m is always negative.

The above claim is false because subtracting a negative integer always results in an addition because two negatives equal a positive.

For example, n is 6 and m is -2; 6 -(-2) will equal 6 + 2 = 8.

Hence, the Awad'claims that "when m is a negative integer and n is a positive integer, n - m is always negative". which is false.
