Answer:

Step-by-step explanation:

hello :  

solve the system :

2x + y = 3 ...(*)

-2y = 14 – 6x ..(**)

use (*) : y = 3-2x

put this value in (**) :

-2(3-2x) = 14-6x

-6+4x = 14 - 6x

10x=20   so : x = 20/10=2

but : y = 3-2x    so : y = 3-2(2) = -1

Reggie is looking up yearly job benefits, the pay is $8.50 an hour for a 40- hour week. His employer also provides fridge benefi
Vika [28.1K]

hello

to solve this problem, we need to work out how much he earns weekly, and then work it up to annually

step 1

calculate the weekly wage into annual wage

he earns $8.50/h and works 40 hours in a week

weekly wage =

\begin{gathered} 8.50\times40=340 \\ \text{ in 1 year, we have 52 weeks} \\ \text{annual wage =340}\times52=17680 \end{gathered}

Raggie earns $17,680 annually

he gets fridge benefit of 19% of his annual wage

we need to find 19% of $17,680

\begin{gathered} \frac{19}{100}=\frac{x}{17680} \\ 100\times x=19\times17680 \\ 100x=335920 \\ x=\frac{335920}{100} \\ x=3359.2 \end{gathered}

he gets additional $3359.2 as fridge allowance

we can add up the total to know his total annual wage

total annual wage = wage + allowance = $17680 + $3359.5 = $21,039.2

his annual expense

commuting = $419

uniforms = $560

parking = $430

total expense = $419 + $560 + $430 = $1,409

net wage = gross wage - expenses

net wage =

\begin{gathered} \text{net wage=} \\ 21039.2-1409=19630.2 \end{gathered}

Reggie's annual wage after expenses = $19630.2

Mummy is 32 years older than her daughter, Aliyah. However, she is 8 years younger than daddy. The total age of the three of the
dem82 [27]

Answer:

Father's age = 64 years

Step-by-step explanation:

Given:

Mummy's age = Aliyah's age + 32

Father's age = Mummy's age + 8

Tota age = 144

Find:

Father's age

Computation:

Assume;

Aliyah's age = a

So,

Mummy's age = a + 32

Father's age = a + 32 + 8

Father's age = a + 40

Aliyah's age + Mummy's age + Father's age = Total age

a + a + 32 + a + 40 = 144

3a + 72 = 144

3a = 144 - 72

3a = 72

a = 24

Father's age = a + 40

Father's age = 24 + 40

Father's age = 64 years
