If people have 6 apples and 46 lemons each, how much would 423 people get?<br><br> [URGENT]
Leto [7]

Answer:

2,538 apples and 19,458 lemons.

Step-by-step explanation:

1 person gets 6 apples and 48 lemons. Now there are different ways of solving this. One is using a calculator and/or multiplication. If 423 people get 6 apples each, we need to get the total by multipling.

423*6=2538 apples.

Now lets do the same thing with the lemons.

423*46=19458 lemons.

There would be a total of 2,538 apples and 19,458 lemons for 423 people.

Determine which of the following ordered pairs satisfies the given system of equations.
alekssr [168]

Answer:

(-3,2)

Step-by-step explanation:

1) -2x+y=8

you need to leave the Y alone on one side. Then, the term -2x goes to the other side with its opposite sign which is +.

y=8+2x

2) y=2x/(5-8)

3) 8+2x=2x/(5-8)

now, you need the x value. for that, you need to leave x alone on one side.

8+2x=2x/(-3)

8+2x=-(2/3)x

8=-(2/3)x-2x

8=-(8/3)x

8/-(8/3)=x

-3=x

4) you now have the x value. you need the y value. for that, replace the x in one of the given equations. let´s use the 1st equation.

-2x+y=8

y=8+2x

y=8+2*(-3)

y=2

result:

x= -3

y=2

When using Cramer's Rule to solve a system of equations, if the determinant of the coefficient matrix equals zero and neither nu
o-na [289]
The answer would be A. When using Cramer's Rule to solve a system of equations, if the determinant of the coefficient matrix equals zero and neither numerator determinant is zero, then the system has infinite solutions. It would be hard finding this answer when we use the Cramer's Rule so instead we use the Gauss Elimination. Considering the equations:

x + y = 3 and <span>2x + 2y = 6
Determinant of the equations are </span>
<span>| 1 1 | </span>
<span>| 2 2 | = 0
</span>
the numerator determinants would be
<span>| 3 1 | . .| 1 3 | </span>
<span>| 6 2 | = | 2 6 | = 0.
Executing Gauss Elimination, any two numbers, whose sum is 3, would satisfy the given system. F</span>or instance (3, 0), <span>(2, 1) and (4, -1). Therefore, it would have infinitely many solutions. </span>
