The new equation after the expression equivalent to x from the first equation is substituted into the second equation is: 2(-4y-9)+5y=-6

Step-by-step explanation:

We will solve the initial steps for substitution method for finding the correct answer

Given equations are:

x+4y = -9\ \  \ \ Eqn1\\2x+5y=-6\ \ \ Eqn2

From equation one

x+4y = -9\\x+4y-4y = -9-4y\\x = -4y-9

Putting x = -4y-9 in equation 2

2(-4y-9)+5y=-6

Hence,

The new equation after the expression equivalent to x from the first equation is substituted into the second equation is: 2(-4y-9)+5y=-6

Sliva [168]

Hi there!

A valley farmer has 26 employees and he pays each of them $410 per week.

After paying them for one week he has $162 dollars left. We need to find how much money he had at first.

So the first step is to multiply $410 on 26 since he gives 410 dollars to each employee, which he has 26.

$410 · 26 = $10,660

So he had $10,660 before he paid the workers, but he still had $162 left. To find out his overall total of money he had we need to add $10,660 and $162 which will be $10,822.

The farmer had $10,822

Hope this helped!~

GaryK [48]

<u>Answer:</u>

D. Urvi multiplied with the reciprocal of the dividend instead of the reciprocal of the divisor.

<u>Step-by-step explanation:</u>

We are given that Urvi solved a fraction division problem using the rule “multiply by the reciprocal.”

The "multiply by the reciprocal” states that you take the reciprocal of the divisor (denominator) and multiply with the dividend (as it is).

But here we can see from the calculations made by Urvi that she took the reciprocal of the dividend and not the divisor.

Therefore, the correct answer option is D. Urvi multiplied with the reciprocal of the dividend instead of the reciprocal of the divisor.
