-2x + 6y = 6

6y - 6 = 2x

6(y-1) = 2x

(1/2) * 6(y-1) = 2x * (1/2)

x = 3(y-1)

------------

If, x = 3(y-1),

-7 * 3(y-1) + 8y = -5

-21 * (y-1) + 8y = -5

-21y + 21 + 8y = -5

21 + 5 = 21y - 8y

26 = 13y

y = 26/13

Therefore: y=2.

----------

If y=2,

x = 3(2-1) = 3

-----------

Answers:

x=3 and y=2.

Anna has made 30 chocolate chip cookies and 54 sugar cookies. She wants to put them in bags for her friends with the same number

NARA [144]

Answer:

Therefore the greatest number of cookies she can put each bag is 14.

Step-by-step explanation:

Given that Anna has made 30 chocolate chip cookies and 54 sugar cookies.

First we have to find out the number of fried or the number of bags.

So to find the number of bags, We need to find out the G.C.D of 30 and 54.

30=5×3×2

54=3×3×3×2

The common divisor of 30 and 54 is = 3×2 = 6

∴The G.C.D of 30 and 54 is 6.

The number of bags is 6.

The number of chocolate cookies each bags is

=(The number of chocolate cookies÷ 6)

=30÷6

The number of sugar cookies each bags is

=(The number of sugar cookies÷ 6)

=54÷6

Therefore the greatest number of cookies she can put each bag is (5+9)=14.

sammy [17]

Answer: In 12 months they will have the same amount, which will be $520.

Step-by-step explanation:

220 + 25m = 100 + 35m

m = month

Subtract 100 from each side

120 + 25m = 35m

Subtract 25m from each side

120 = 10m

Divide each side by 10

12 = m

A candy store sells bags of fruit-flavored candy for $2 and chocolate candy for $3. Jasmine spends $54 on candy for her friends.

34kurt

Answer:

2x + 3y = $54

Step-by-step explanation:

Standard Form ~ Ax + By = C

A and B in this case are just going to be numbers, they are just for substitution purposes.

Since x is fruit flavored candy and y is Chocolate, we can substituce the Fruit for A and Chocolate for B.

Now, we have 2x + 3y = C

The C is going to be the total cost. Therefore we have ~

2x + 3y = $54
