For this case, the first thing we must do is define variables.
We have then:
x: initial amount of cards
We now write the equation that models the problem:
Therefore, the initial amount of cards is 300
Answer:
Latoya had 300 cards at the beginning
Answer:
A.Yes.1st group is nothing ,the 2nd group is nothing,and so on .The 4th group is which does not equal 256 is the correct answer
Answer:
No Solution.
Step-by-step explanation:
y=-3x+2
y=-3x-7
------------
-3x+2=-3x-7
-3x-(-3x)+2=-7
-3x+3x+2=-7
2=-7
no solution
Answer:
TR = 23
Step-by-step explanation:
first we have to find TS, so we subtract 16 from 4 to get 12. then we can add 12 and 11 to get TR
First, write an equation system based on the problem
An equation for "Jami and Mami together had 32" is
⇒ j + m = 32 (first equation)
An equation for "If Mami gives Jami 5, they'll have the same amount"
⇒ m - 5 = j + 5 (second equation)
Second, simplify the equation. I simplify the second equation
m - 5 = j + 5
m = j + 5 + 5
m = j + 10
Third, subtitute m with j+10 in first equation
j + m = 32
j + j + 10 = 32
2j + 10 = 32
2j = 22
j = 11
Fourth, subtitute j with 11 in second equation
m = j + 10
m = 11 + 10
m = 21
Jami had $11, Mami had $21
