I know these numbers from a triangle because 24+30=54 and 6square root 43 is about 39
Answer:
x-73
Step-by-step explanation:
Let x=Jose's height. If it says "less than," then that is subtraction. Since Jose's height is not defined, there is no specific number that can be used to describe "73 less than twice Jose's height," so I use the variable x, and then subtract 73.
Answer:
60
Step-by-step explanation:
Given the following :
Half of baseball card got wet and was ruined
Number of baseball cards bought has replacement for the ruined cards = 20
Total number of baseball cards now = 50
The initial number of baseball cards =?
Let the initial number = y
Number that hit ruined = half of initial = y/2
Hence,
y - y/2 + 20 = 50
y/2 + 20 = 50
y/2 = 50 - 20
y/ 2 = 30
y = 30 * 2
y = 60
Hence, he started with 60 baseball cards.
Simplify 8/3c to 8c/3
8c/3 - 2 = 2/3 c - 12
Simplify 2/3 c to 2c/3
8c/3 - 2 = 2c/3 - 12
Multiply both sides by 3
8c - 6 = 2c - 36
Simplify 8c - 6 - 2c to 6c - 6
6c - 6 = -36
Add 6 to both sides
6c = -36 + 6
Simplify -36 + 6 to -30
6c = -30
Divide both sides by 6
c = -30/6
Simplify 30/6 to 5
<u>c = -5</u>
