Hiya! So instead of the word "what", I am going to use 't' as the missing term in this equation

So basically, 14= t x 2/3

1. As you would do with any type of solve-for-x equation, you have to divide 2/3 on both sides of the equation.

To divide a by a fraction, you must turn it into a
reciprocal: "a mathematical expression or function so related to another that their product is one; the quantity obtained by dividing the number one by a given quantity." (via Google definition)
Trust me, it's not as hard as it looks.

To turn the fraction into a reciprocal, you have to flip the numerator and denomonater.

2 = numerator
-
3 = denominator

When you flip it, you get:

3
-
2

If you are still confused, look at this: https://www.mathsisfun.com/reciprocal-fraction.html

2. As simple as that. After you turn the fraction into a reciprocal, you must multiply that fraction.

Multiply 3/2 by 14.

3 14 42
- x - = - = 21
2 1 2

21 = t x 2/3

Since to have to multiply on both sides, you have to divide 2/3 by 3/2 which cancels itself out.

21 = t x 2/3 divide by 2/3

It poofs out of existance.

Dont ask why.

So now we are left with:
t = 21

That is the answer. Viola!

To check your work, fill in the 't' value with 21 into the orginal problem!

14 = t x 2/3

14 = (21) x 2/3

(You are not dividing the fraction anymore so there is not need to create the reciprocal)

In the end, 14 = 14, which proves the problem to be correct. Hope this helped, if you have any questions just ask in the comments!

Answer from: Quest

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

Answer from: Quest

a. we have two

lines: y = 4-x and

y = 8-x^-1

given two simultaneous equations that are both to be

true, then the solution is the points where the lines cross. the intersection is

where the two equations are equal. therefore the solution that works for both

equations is when

4-x = 8-x^-1

this is where the two lines will cross and that is the

common point that satisfies both equations.

b. 4-x = 8-x^-1

x 4-x 8-x^-1

-3 7

8.33

-2 6 8.5

-1 5 9

0 4

1 3

2 2

7.5

3 1 7.67

the table shows that none of the x values from -3 to 3 is

the solution because in no case does

4-x = 8-x^-1

to find the solution we need to rearrange the equation to

find for x:

4-x = 8-x^-1

multiply both sides with x:

4x-x^2 = 8x-1

x^2+4x-1=0

x= -4.236, 0.236

therefore there are two points that satisfies the

equation.

find y:

x=-4.236

y = 4-x = 4 – (-4.236)

= 8.236

y = 8-x^-1 = .236)^-1

= 8.236

x=0.236

y = 4-x = 4 – (0.236) = 3.764

y = 8-x^-1 = 8-(0.236)^-1

= 3.764

thus the two lines cross at 2 points:

(-4.236, 8.236) & (0.236, 3.764)

c. to solve

graphically the equation 4-x = 8-x^-1

we would graph both lines: y = 4-x and y

= 8-x^-1

the point on the graph where the lines cross is the

solution to the system of equations.

just graph the points on part b on a cartesian coordinate

system and extend the two lines. the

solution is, as stated, the point where the two lines cross on the graph.
