The perimeter of a rectangular garden is 318 feet. If the width of the garden is 68 feet, what is its length

Answers

Answer 1

Answer: perimeter you add all the sides together. So take 318-68-68=182 then take 182/2 and you get 91 so the length is 91. Hope this helps.

Charlie solved an equation, as shown below:Step 1: 5x = 30
Step 2: x = 30 – 5
Step 3: x = 25

Part A: Is Charlie's solution correct or incorrect? If the solution is incorrect, explain why it is incorrect and show the correct steps to solve the equation.
Part B: How many solutions will this equation have?

Answers

Part A : His solution is incorrect because whenever you have a number "connected to" the variable, you have to divide. & what you do to one side, you have to do to the other. So, for step 2, instead of subtracting 5, you divide by 5. By doing this, you will then have 'x' by itself on the left, & on the right 30/5= 6. So, x=6.

Showing...
Step 1: 5x=30
Step 2: 5x/5=30/5 (the 5s cancel out, leaving you just x on the left)
Step 3: x=6

Part B : This solution will have only 1 answer, & that answer is 6. -6 wouldn't be counted as one because if you plug -6 into the equation as x, the sides won't equal, you'll have -30=30 which isn't true.

Hope this makes sense & helps you ! (:

Find the equivalent fraction of 3/7 having denominator 20

Answers

Answer:

x= the numerator

3/7 = x/20

7x=20*3

7x=60

x=60/7

equivalent fraction of 3/7 having denominator 20: 3/7 = $(60/7)/(20)$

we check:

(60/7)/20= 60/7*20 = 60/140 =6/14 =3/7

The surface area of a cube is 96 square feet. Find the volume of the cube.

Answers

cube has six identical walls

96ft² : 6 = 6 ft² - one wall surface

pattern on the surface of the cube
A = a²
a - the edge of the cube

A = a² ⇔ a=√A
a = √(16ft)² = 4ft
V = volume
V = a³
V = (4ft)³ = 64 ft³
