Answers

Answer 1
Answer:

Answer:

a: 9

b: 27

Step-by-step explanation:

Let's define  

P = amount of model cars that Peter has

J =amount of model cars that Jade has

A = amount of model cars that Andre has

a:  We need to find out how many model cars does Peter have, i.e. we need to find out P.

We know that Andre has 36 model cars and he has 4 times as many model cars as Peter. If we write that as an equation, we have

A = 4*P = 36

Now we just have to divide by 4:

4*P/4 = 36/4

P = 9

Peter has 9 model cars.

b: Now we need to find out how many model cars does Jade have, i.e. we need to find out J.

We will resolve it as in part a:

Peter has 9 model cars and he has one-third as many model cars as Jade, that is

P = 1/3*J = 9

We multiply by 3 and we have:

1/3*J*3 = 9*3

J = 27

Jade has 27 model cars.

Answer 2
Answer: p = how many cars Peter has
j = how many cars Jade has
a = how many cars Andre has
p x 4 = how many cars Andre has (36 model cars)
>>>TO FIND HOW MANY MODEL CARS PETER HAS:
p x 4 = 36
36 / 4 = 9
your equation to find how many model cars Peter has is:
36 / 4 = 9
So, Peter has 9 model cars.
>>>TO FIND HOW MANY MODEL CARS JADE HAS:
36 / 4 = how many cars Peter has (9)
Now, you are given the info that Jade has THREE TIMES (3x) as many cars as Peter already.
So, your equation for this one is:
9 x 3 = 27
So Jade has 27 model cars.

---- Jade has 27 model cars.
---- Andre has 36 model cars.
---- Peter has 9 model cars.

equation for a. 36 / 4 = p
equation for b. 9 x 3 = j

How do you solve this equation: 5w – 4w + 4 = 14 ?

Answers

First combine the like terms 5w and -4w to get just w.
so now the problem looks like:
 
w + 4= 14

subtract 4 from each side now. and you get the answer:

w = 10
First multiply five times two, which equals ten. Then, multiply four times zero which equals zero. Finally add four and you get fourteen.

5w - 4w + 4 = 14
5x2 -4x0 +4 =14
