j = # of jars
b = # of buckets
y = total # of rocks
2j + 3b = y (2 rocks per jar, 3 rocks per bucket)
Because Joy has 3 jars you can plug 3 in for "j", and because she has 4 buckets you can plug in 4 for "b"
2(3) + 3(4) = y
6 + 12 = y
18 = y

Answer:
$50
Step-by-step explanation:
Weekly paycheck to be deposited = 70%
This week's deposit = $35
Therefore, we have to determine how much is Alex weekly paycheck.
To find this, we have to use unitary method.
According to the Question
Total weekly paycheck = (total deposit/ percentage to be deposited)
Therefore, Weekly paycheck = ($35/70%)
Weekly paycheck = $50.
It means Alex gets $50 per week.
Answer:
{10,8}
Step-by-step explanation:
-3x + 4y = -62
4x + 5y = 0
let's eliminate the x
-3x + 4y = -62 | x -4 |
4x + 5y = 0 | x 3 |
12x - 16y = 248
12x + 15y = 0
-------------------- -
-31y = 248
y = 248/(-31) = 8
since you must do this proble with elimination, we cant use subtitution. so we repeat the way once more to find x (eliminate y)
-3x + 4y = -62 | x 5 |
4x + 5y = 0 | x 4 |
-15x + 20y = -310
16x + 20y = 0
-------------------- -
-31x = -310
x = -310/-31 = 10
