To answer this you need to find the LCD (least common denominator) 2/3times4=8/12 and 3/4times3=9/12 and 9+8=17 then 17-12=5 so she bought 1 5/12 yards of ribbon

Farmer Brown has 42 animals, which are cows and chickens. They have a total of 120 legs. Write a system of equations, show your

SCORPION-xisa [38]

Answer:

The system of equations is:

x + y = 42

4x + 2y = 120

And there are 24 chickens.

Step-by-step explanation:

We know that the total number of cows (x) plus the total number of chickens (y) is 42, because Farmer Brown has 42 animals.

We also know that cows (x) have 4 legs and so 4 times the number of cows is the number of cow legs. And chickens (y) have 2 legs, so the number of chickens times two represents the total chicken legs. The sum of 4x + 2y is 120 because there are 120 legs in total.

To solve the system of equations, first solve each equation for y.

In the first equation:

x + y = 42

Subtract x from both sides to isolate y.

y = 42 - x

Second equation:

4x + 2y = 120

Subtract 4x from both sides

2y = 120 - 4x

Divide both sides by 2

y = 60 - 2x

Now that the y's are isolated in both equation, you can put them into 1 equation. Where y = y:

y = 42 - x

y = 60 - 2x

42 - x = 60 - 2x

Add 2x to both sides

42 + x = 60

Subtract 42 from both sides

x = 18

Since x is the number of cows, we know that Farmer Brown has 18 cows.

Now we can substitute the x value into one of the equations:

y = 42 - x

y = 42 - (18)

y = 24

The number of chickens is represented by y, so there are 24 chickens.

-3(x+2)=12. solve for x

bagirrra123 [75]

Steps to solve:

-3(x + 2) = 12

~Distributive Property

(-3 * x) + (-3 * 2) = 12

~Simplify

-3x - 6 = 12

~Add 6 to both sides

-3x - 6 + 6 = 12 + 6

~Simplify

-3x = 18

~Divide -3 to both sides

-3x/-3 = 18/-3

~Simplify

x = -6

Best of Luck!

Use IF functions to calculate the regular pay and overtime pay based on a regular 40-hour workweek in cells E5 and F5. Pay overt

g100num [7]

Excel formulas are expressions used to perform computation.

The Excel formula to enter in cell E5 is =IF(D5<$B$21,D5,$B$21) * C5
The Excel formula to enter in cell E5 is =IF(D5>$B$21,(D5-$B$21) * C5 * $B$22, 0)

<h3 /><h3>The regular pay</h3>

From the complete question, cell B21 represents base work hour

So, we start by checking if the work hour in cell D5 is less than the base work hour in cell B21

If yes, the work hour remains D5; otherwise the work hour is cell B21

The work hour is then multiplied by the rate in cell C5

Hence, the Excel formula to enter in cell E5 is =IF(D5<$B$21,D5,$B$21) *

<h3>The overtime pay</h3>

Here, we start by checking if the work hour in cell D5 is greater than the base work hour in cell B21

If yes, the overtime hour the difference between D5 and B21; otherwise the overtime hour and pay is 0

The over time hour if there is, is then multiplied by the rates in cells C5 and B22

Hence, the Excel formula to enter in cell E5 is =IF(D5>$B$21,(D5-$B$21) * C5 * $B$22, 0)
