Answer:

x =23

Step-by-step explanation:

We can use a ratio to solve

20 backslappers        460 backslappers

------------------------- = ------------------------------

1 wallflower                    x wallflowers

Using cross products

20*x = 460*1

Divide each side by 20

20x/20 = 460/20

x =23

Drag steps in the given order to evaluate this expression. <br><br> (4)(−3)−5−3(−6)
never [62]

Answer:

1

Step-by-step explanation:

using PEDMAS(parentheses, exponents, division, multiply, addition, subtraction) to solve the problem

First we multiply (4)(-3)

(4)(−3)−5−3(−6)

Then multiply -3(-6)

(-12)-5-3(-6)

=-12-5+18

subtract 12-5

-12-5+18

=-17+18

Adding -17+18 gives us 1.

Therefore,  (4)(−3)−5−3(−6) is 1.

3. Solve using substitution.<br> x - y = 4<br> 3x - 2y = -5
Vedmedyk [2.9K]

<u>Given</u>:

The system of linear equations are x-y=4 and 3x-2y=-5

We need to determine the solution to the system of equations using substitution method.

<u>Solution</u>:

The solution can be determined using the substitution method.

Let us substitute x=4+y in the equation 3x-2y=-5

Thus, we have;

3(4+y)-2y=-5

12+3y-2y=-5

          12+y=-5

                  y=-17

Thus, the value of y is -17.

Substituting y=-17 in the equation x-y=4, we get;

x+17=4

       x=-13

Thus, the value of x is -13.

Hence, the solution to the system of equations is (-13,-17)
