Whiskers the cat weighs 2 2/3 kg. Piglo weighs 4kg. For each question , write a myipulcation and a division equation, decide whe

Liula [17]

Answer:

1) x= 3/2= 1 1/2

2) x= 2/3

Step-by-step explanation:

1)How many times as heavy as Whiskers is Piglio?

a) Write a multiplication equation for the question.

2 2/3 kg * [x]= 4kg

b) Write a division equation for the question.

4/ 2 (2/3) = x

c) Is the answer greater than 1 or less than 1?

Ans) Greater than 1

d) Find the answer

4/ 8/3= x

x= 3/2= 1 1/2

Pigilo is 1 1/2 times as heavy as whiskers

2)How many times as heavy as Piglio is Whiskers?

a) Write a multiplication equation for the question.

4 kg * [x]= 2 2/3 kg

b) Write a division equation for the question.

2 (2/3)/4 = x

c) Is the answer greater than 1 or less than 1?

Ans) Less than 1

d) Find the answer

8/3/4= x

8/3 * 1/4= x

2/3= x

A game costs $39.00. But the new special edition version is going to be $56.94. What is the increased percent?

astraxan [27]

Answer:

46%

Step-by-step explanation:

Step 1: Make an expression

$39.00 * x = 56.94$

$39x = 56.94$

Step 2: Divide both sides by 39

$39x / 39 = 56.94 / 39$

$x = 1.46$

Step 3: Find the percent

$1.46 - 1$ -> Gives us the increased percent

$0.46 * 100$

46%

Answer: 46%

Solve the equation. 5x + 6 = 2(2x – 3) what dose x =

Lady_Fox [76]

Answer:

x=−12

Step-by-step explanation:

Let's solve your equation step-by-step.

5x+6=2(2x−3)

Step 1: Simplify both sides of the equation.

5x+6=2(2x−3)

5x+6=(2)(2x)+(2)(−3)(Distribute)

5x+6=4x+−6

5x+6=4x−6

Step 2: Subtract 4x from both sides.

5x+6−4x=4x−6−4x

x+6=−6

Step 3: Subtract 6 from both sides.

x+6−6=−6−6
