2x + 9 = 35
We subtract 9 in both sides:
2x + 9 - 9 = 35 - 9
2x = 26
We then divide 2 in both sides:
x = 13
Answer:
Angie=x
Susan = x+3
Rebecca = 3(x+3)
Total = 5x+12
If Angie has 4 then the total is 32
Step-by-step explanation:
Angie has x games
Susan has 3 more games than Angie has
Susan = x+3
Rebecca has 3 times more games than Susan
Rebecca = 3Susan
We know Susan has x+3 so replacing it in
Rebecca = 3 (x+3)
The total number of games is Angie + Susan + Rebecca
x + x+3 + 3(x+3)
Distributing the 3
x + x+3 + 3x+9
Combining like terms
5x+12
The total number of games is
5x+12
If Angie has 4 games, x=4
The total number of games is 5(x)+12
5*4+12
20+12
32
Given:
i) 3, -5, -2, 1
ii) -1, -8, -7, -2
iii) -2, -4, 0, 2
To find:
increasing order of the given numbers.
Solution:
Increasing order: We need to start from the smallest number, then write larger number and end with the largest number.
We know that all negative numbers are less than the positive numbers and larger negative value is always the smaller one.
For example: -3 is less than -1.
i) We have,
3, -5, -2, 1
So, the increasing order of these number is -5, -3, -2, 1.
ii) We have,
-1, -8, -7, -2
So, the increasing order of these number is -8, -7, -2, -1.
iii) We have,
-2, -4, 0, 2
So, the increasing order of these number is -4, -2, 0, 2.
