Consider the system of equations.

Xelga [282]

Answer:

D and C

Step-by-step explanation:

Given the 2 equations

3x - y = 5 → (1)

2x + 3y = - 15 → (2)

Multiplying (1) by 3 and adding to (2) will eliminate the y- term

9x - 3y = 15 → (3)

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

11x + 0 = 0

11x = 0 ⇒ x = 0

Substitute x = 0 into either of the 2 equations and solve for y

Substituting into (2)

2(0) + 3y = - 15

0 + 3y = - 15

3y = - 15 ( divide both sides by 3 )

y = - 5

solution is (0, - 5 )

A man earns 12,000 per year, 10% of it was spent on transport while 5% of the salary went as tax. He spent 80% of the remainder

weqwewe [10]

Answer:

Amount left = 2040

Step-by-step explanation:

Given that:

Per year salary = 12,000

Amount spent on transport = 10%

Transport = $\frac{10}{100}*12000$ = 0.1 * 12000

Transport = 1200

Tax = 5%

Tax = 0.05 * 12000

Tax = 600

Total = 1200 + 600 = 1800

Amount left = 12000 - 1800 = 10200

Food = 80% of remainder

Food = 0.8 * 10200

Food = 8160

Amount left after food = 10200 - 8160 = 2040

Hence,

Amount left = 2040
