Solve 3x – ly= 11 and -2x – 4y=-26 by elimination
Ede4ka [16]

Answer:

(5, 4 )

Step-by-step explanation:

Given the 2 equations

3x - y = 11 → (1)

- 2x - 4y = - 26 → (2)

Multiplying (1) by - 4 and adding to (2) will eliminate the y- term

- 12x + 4y = - 44 → (3)

Add (2) and (3) term by term to eliminate y

- 14x + 0 = - 70

- 14x = - 70 ( divide both sides by - 14 )

x = 5

Substitute x = 5 into either of the 2 equations and solve for y

Substituting into (1)

3(5) - y = 11

15 - y = 11 ( subtract 15 from both sides )

- y = - 4 ( multiply both sides by - 1 )

y = 4

solution is (5, 4 )

A restaurant buys mustard in 3/4 pound jars. If a 27 pound carton was bought, how many jars would be in the carton?
Nostrana [21]

Answer:

36

Step-by-step explanation:

Divide the carton weight by the weight of 1 jar

27 ÷ \frac{3}{4}

= 27 × \frac{4}{3}

= \frac{27(4)}{3}

= \frac{108}{3}

= 36

There are 36 jars in a carton
