Answer from: enazer

Dividing decimals by whole numbers tends to look intimidating, but it's just like any normal number. Think of 1.78 as 178. It seems easier to divide 178 by two than it is to divide 1.78 by two but you come out with the same numbers. 178/2=89 1.78/2=.89 If you choose to change the number from a decimal to a regular number like I did, you need to remember to move the decimal back the same number of spaces that you had moved it. In this you had to move the decimal to the right two spaces so it came after the 8, so when you get the answer, you have to move the decimal to the left two spaces starting from the right of the digit in the one's place. In this case, that would be the 9 in 89. If you don't like that answer, then you can always break the number up to 1, .7, and .08 then divide each individual number by two, giving you .5, .35, and .04. Then you add them all together in the end to get .89. I hope this helped!

Answer from: 3mina

you can change 1.78 to 178 and then just divide 178 by 2= 89 and then you count the number of spaces before the decimal in 1.78 which is two so with 89 you would move the decimal in two spaces to become .89. so overall your equation would be 1.78÷2=.89

no, because the sides are not congruent

Is the following shape a square? how do you know?

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.
