Fractions: Multiplying mixed (a whole number with a fraction) numbers

1 answer:

<span>You must change the whole number into an improper fraction. Just for an example, if you were told to solve 5 x 1/5, you must make 5 an improper fraction, which is 5/1. Then you just multiply the fractions to get 1.

My answer is similar to the one above!! Sorry!!</span>

Given that the following two geometric series(meetkundige reekse) are covergent 1+x+x²+x³+... And 1-x+x²-x³+... Determine the va

Oksanka [162]

The sets are (1,-1) or (-1,1)

Lets see

Take until 4terms

#1

$\\ \rm\longmapsto S_4=1+1+1^2+1^3=1+1+1+1=4$ (1,-1)

$\\ \rm\longmapsto S_4=1+(-1)+(-1)^2+(-1)^3=1-1+1-1=0$ (-1,1)

#2

$\\ \rm\longmapsto S_4=1-(-1)+(-1)^2-(-1)^3=1+1+1+1=4$ (1,-1)

$\\ \rm\longmapsto S_4=1-1+(1)^2-1^3=1-1+1-1=0$ (-1,1)

Hence verified

Another set can be (0,0)

Proof:-

$\\ \ast\rm\longmapsto S_3=1+0+0^2=1$

$\\ \ast\rm\longmapsto S_3=1-0+0^2=1$

Hence verified.

So 32 gave their speeches yesterday,

7 gave today

Total number that has given is

32 + 7 = 39

Therefore the number remaining are

62 - 39 = 23

Given the equation y − 4 = three fourths(x + 8) in point-slope form, identify the equation of the same line in standard form.

IRINA_888 [86]

Answer:

$3x-4y=-40$

Step-by-step explanation:

The standard form of a linear equation is $ax+by=c$ .

The given line has equation:

$y-4=\frac{3}{4}(x+8)$

This is the point-slope form of the given line.

To find the standard form, we clear the fraction

$4y-16=3(x+8)$

We expand the parenthesis now to get:

$4y-16=3x+24$

We group the variables on the LHS and the constants on the RHS.

$4y-3x=24+16$

$-3x+4y=40$

Multiply through by -1

$3x-4y=-40$

This is of the form: $ax+by=c$ .
