Answer:
240
Step-by-step explanation:
Multiply them altogether.
5 x 4 x 4 x 2 x 1.5 = 10 x 24 = 240
(-2 ,-15)
(-1, -7)
(0,1)
(1, -7)
(2, - 15)
The distributive law is satisfied if the numbers 1,2, and 3 are used as multyplying factors.
<h3>What is the distributive law?</h3>
This is basic mathematical law that states:
- A multiplied by (b+c) equals (a x b) + (a x c)
<h3>Is this law satisfied if there are three numbers involved?</h3>
The law is always satisfied if one of the numbers is 1. Here is an example
or
- (2x1) + (2x2) + (2x3)
- 2+4+6 = 12

38, 20, 12, 2, 1 and 4 only.
A)
s = sweater
j = jeans
Equations:
4s + 2j = 140
2s + 3j = 150
B)
4s + 2j = 140
2s + 3j = 150
Multiply (-2) to the second equation
-2 (2s + 3j = 150)
-4s - 6j = -300
Now you have the equations:
4s + 2j = 140
-4s - 6j = -300
-----------------------------add
-4j = -160
j = 40
4s + 2(40) = 140
4s + 80 = 140
4s = 60
s = 15
The cost for a sweater is $15 and the cost for a jean is $40
We used the elimination method to solve the system of equations.
C)
Each pair of jean, she will buy 3 sweaters so total = 40 + 3(15) = $85
Total cost for 1 pair of jeans and 3 sweaters = $85
If she has $225 the
$225 / $85 = 2.64
2 jeans = 2 x 40 = $80
6 sweaters = 6 x $15 = $90
So She can only buy 2 jeans and 6 sweaters
