Answer:

(x,y)=(2,-3)

Step-by-step explanation:

6x+2y=6

7x+3y=5

Multiply both sides by 3

18x+6y=18

7x+3y=5

Multiply both sides by -2

18x+6y=18

-14x-6y=-10

Eliminate one variable by adding the equations

4x=8

x=2

Substitute the value of x to get y

6(2)+2y=6

y=-3

x=2

y=-3

cupoosta [38]

Answer:

Ted will need $3\frac{3}{4}$ cups of pretzels to make 15 cups of trail mix.

Step-by-step explanation:

Ted is making trail mix for a party. He mixes 1 1/2 cups of nuts, 1/4 cup of raisins, and 1/4 cup of pretzels.

So, 1/4 cup of pretzels to make 1 trail mix

x cups of pretzels to make 15 trail mix

Using the ratio and proportional

∴ x = (1/4) * 15 = 3.75 = $3\frac{3}{4}$ cups.

Ted will need $3\frac{3}{4}$ cups of pretzels to make 15 cups of trail mix.

2 x 1’- 2 3/8” = ? Please help

Nat2105 [25]

Answer:

$=-\frac{3}{8}$ is the answer.

Step-by-step explanation:

We have to solve the given expression 2 × 1 - 2 3/8

$2\times 1-2\frac{3}{8}$

$=\frac{2}{1}-\frac{19}{8}$ [Now we take LCF of denominators of both the fractions]

$=\frac{(16-19)}{8}$

$=-\frac{3}{8}$

So the final answer is $=-\frac{3}{8}$
