4 0

Answer:

$50

Step-by-step explanation:

Weekly paycheck to be deposited = 70%

This week's deposit = $35

Therefore, we have to determine how much is Alex weekly paycheck.

To find this, we have to use unitary method.

According to the Question

Total weekly paycheck = (total deposit/ percentage to be deposited)

Therefore, Weekly paycheck = ($35/70%)

Weekly paycheck = $50.

It means Alex gets $50 per week.

Nswer two questions about Systems A AA and B BB: System A AA start text, end text System B BB { − 3 x + 12 y = 15 7 x − 10 y = −
rjkz [21]

Answer:

(Choice C) C Replace one equation with a multiple of itself

Step-by-step explanation:

Since system A has the equations

-3x + 12y = 15 and 7x - 10y = -2 and,

system B has the equations

-x + 4y = 5 and 7x - 10 y = -2.

To get system B from system A, we notice that equation -x + 4y = 5 is a multiple of -3x + 12y = 15 ⇒ 3(-x + 4y = 5) = (-3x + 12y = 15).

So, (-x + 4y = 5) = (1/3) × (-3x + 12y = 15)

So, we replace the first equation in system B by 1/3 the first equation in system A to obtain the first equation in system B.

So, choice C is the answer.

We replace one equation with a multiple of itself.

Use substitution to solve each system of equations <br> Y=2x-2<br> Y=x+2
Alik [6]
Y = 2x - 2 ⇒ 2x - y = 2  ⇒ 2x - y = 2
y = x + 2  ⇒ x - y = -2   ⇒ <u>2x - 2y = -4</u>
                                                 <u>3y</u> = <u>6</u> 
                                                  3     3
                                                   y = 2
                                            2x - 6 = 2
                                            <u>      +6   +6</u>
                                                 <u>2x</u> = <u>8</u>

                                                   x = 4
                                             (x, y) = (4, 2)
