Answer:

x = -4, y = 1/3

Step-by-step explanation:

=> x = 3y-5 (Equation 1)

=> 2x+12y = -4 (Equation 2)

Putting (1) in (2)

=> 2(3y-5)+12y = -4

=> 6y-10+12y = -4

=> 18y = -4+10

=> 18y = 6

Dividing both sides by 18

=> y = 6/18

=> y = 1/3

Putting y = 1/3 in Equation 1

=> x = 3(1/3)-5

=> x = 1-5

=> x = -4

X=3y-5
2x+12y=-4

(-2)x=-6y+10
2x+12y=-4
12y=6
y=1/2

x=3y-5
2x+12y=-4

(-4)x=-12y+20
2x+12y=-4
-2x=16
x=-8

Find the largest consecutive integers whose sum is less than 46

zmey [24]

The largest consecutive integers whose sum is less than 46 are x= 21 and x+1=22

Step-by-step explanation:

Let the integers be:

x and x+1

The sum of these integers is less than 46

$x+(x+1)$

Solving and finding value of x:

$x+(x+1)$

So, the integers will be less than 22.5

The largest numbers are: 21 and 22

So, the largest consecutive integers whose sum is less than 46 are x= 21 and x+1=22

Scott has $500 in the bank. He withdraws the same amount of money each week for 12 weeks, at which point he has $20 left in the

Gre4nikov [31]

Scott knew that the only chance we would have to answer this problem would be if he kept his money in a bank that pays no interest, so that's what he did. The bank simply stored his money in a mayonnaise jar under a tightly-guarded mattress, and he was allowed to come in and take some out of it each week.

He started with $500. He withdrew (500 - 20) = $480 in 12 weeks.

So he must have come in and picked up 480/12 = $40 each week.
