Mathematics
1 answer:
Serga [27]3 years ago
8 0

Answer:

so the sides would have to be equal for all sides

2x-3=3x-8    -3=x-8    x=5

x-12, 4x-1, neither, or both?

2x-3=x-12       x-3=-12      x=-9

4x-1=3x-8      x-1=-8      x=-7

2x-3=4x-1      -3=2x-1    -4 = 2x    x=-2

3x-8=x-12       2x-8=-12     2x=-4    x=-2

So the answer is neither or C

describe the steps you would follow to write a two step equation you can use to solve a real world problem
RideAnS [48]
Pretend the equation was 2x - 4 > 8
The first step (of the two) would be to add 4 to the (-4) and to the other side of the equation (+4) to the 8, first. (You wouldn't use the number with variable in the first step) Then you would rewrite the equation: 2x > 12 (it's now 12 because you added the 4 to the 8). The second step is to divide 2x by 2x and do the same with 12. By dividing both sides with the coefficient, will help find "x". 12/2 is 6, therefore x > 6. (the last step would be to graph the expression if needed to)

A rectangular swimming pool has a perimeter of 96 ft. The area of the pool is 504 ft2. Which system of equations models this sit
gregori [183]

Answer:

2l + 2w = 96 ..... eqn1

lw = 504 ...... eqn2

Step-by-step explanation:

To model this case where we have two unknowns l and w, we need two equations.

Firstly, the perimeter of a rectangle is given by

2l + 2w = p

Where l,w and p are length, width and perimeter of the rectangle respectively.

Hence,

2l + 2w = 96 ... eqn1

Secondly, the area of a rectangle is given by

Length × width = Area

Hence,

l × w = 504

lw = 504 ... eqn2

With these two equations the solutions to the length and width of the rectangular pool can be derived.

Examine this system of equations. Which numbers can be multiplied by each equation so that when the two equations are added toge
podryga [215]

Answer:

18 times the first equation and 8 times the second equation

Step-by-step explanation:

we have

\frac{1}{4}x-\frac{1}{6}y=5 ------> first equation

\frac{4}{5}x+\frac{3}{8}y=10 ------> second equation

step 1

Multiply the second equation  by 8 both sides to remove the fraction in the variable y

8(\frac{4}{5}x+\frac{3}{8}y)=10(8)

\frac{32}{5}x+3y=80

step 2

Multiply the first equation  by 18 both sides to obtain the coefficient -3 in the variable y

18(\frac{1}{4}x-\frac{1}{6}y)=5(18)

\frac{18}{4}x-3y=90

step 3

Adds the new equation 1 and equation 2

\frac{18}{4}x-3y=90\\\\ \frac{32}{5}x+3y=80\\ -------

The y-term is eliminated

therefore

The answer is

18 times the first equation and 8 times the second equation
