1. A rectangular garden has a perimeter of
120 feet. The length of the garden is 24 feet
greater than twice the width. The system of
linear equations 21 +2w = 120 and 1-2w = 24
represents this situation, where I is the
length of the garden and wis the width. Find
the length and width of the garden.

Answers

Answer 1

Answer:

Length: 48

Width: 12

Step-by-step explanation:

Substition

l - 2w = 24

I = 60 - w

60 - w - 2w = 24

60 - 3w = 24

-3w = -36

w = 12

Substitute it into the equation to get the length.

l = 60 - 12

l = 48

hope it's helpful ❤❤❤❤

THANK YOU.

The expression is equivalent to the given expression is 5k+11l. Therefore, option B is the correct answer.

What is an equivalent expression?

Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.

The given expression is 3k+5l+6l+2k.

Group like terms and simplify, we get

(3k+2k)+(5l+6l)

= 5k+11l

The expression is equivalent to the given expression is 5k+11l. Therefore, option B is the correct answer.

Answers

Answer:

x=15, y=12, z=20

Step-by-step explanation:

y is the geometric mean of the two segments it divides.

9 · 16 = y^2

y=12

Use the pythagorean theorem to find x and z.

16^2 + 12^2 = z^2

z^2 = 400

z=20

9^2 + 12^2 = x^2

x^2 = 225

x=15

A metal pipe is 33 3 /4 inches long. If you cut the pipe into pieces that are each 3 3 /4 inches long, how many total pieces will you have?

Answers

3 3/4 = 15/4

We have to deal with each rod since they are not combined.

24/(15/4) = 24(4/15) = 32/5 = 6 2/5

The 2/5 is waste.

6(32) = 192 pieces



11. What is the perimeter of the top of a square pizza box that just manages to hold a circular pizza whose radius is 70 cm?

Answers

Multiply the radius by 2 to get the diameter: 70cm x 2 = 140cm. Then, to find the perimeter of the pizza box, multiply the radius by 4 since there are 4 sides in a square pizza box: 140cm x 4 = 560cm. Hope this helps!

Answer:

Step-by-step explanation:

That x in the denominator has a power of 1 even if its not visually there. When you multiply exponents, you add them.

[tex]x^1*x^-^2=x^-^1[/tex]

Now you have this

[tex]x^-^6/x^-^1[/tex]

When you divide exponents, you subtract them

[tex]x^-^5 = 1/x^5[/tex]

4. One number is 16 more than another. The ratio of the smaller number to
the larger number is 3: 7. What is the value of the smaller number?

Answers

Answer:

12

Step-by-step explanation:

So if the difference between the two number is 16 and the distance between the two numbers in the ratio is 4, that means the real numbers are 4 times greater than the ratio (because 4 * 4 = 16).

This means that you can multiply both sides of the ratio by 4 to get the two numbers 3: 7 --> 3*4: 7 * 4 --> 12: 28.

This means that the smaller number is 12.
