Answer:

u + v

=2-i + -4+ 5i

=2-4+5i-1i

= -2+4i

u- v

=2- 1i - -4 + 5i

=2+4 +5i-1i

=6+4i

u × v

=2- 1i × -4 + 5i

= -8 +4i +10i -5i

= -8 + 14i - 5i

= -8 + 9i

u ÷ v

= 2- 1i ÷ -4 +5i

= -2+2.5i - 4i - 5

= -2-5 + 2.5i - 4i

Jackie has 1 6/12 pitchers of fruit juice. She and her friend drink 4/12 of a pitcher. How much fruit does Jackie have left?

goldfiish [28.3K]

Answer:

$1\frac{1}{6}\ pitchers\ of\ fruit\ juice$

Step-by-step explanation:

we know that

To find out how much fruit Jackie has left, subtract 4/12 from 1 6/12.

Convert mixed number to an improper fraction first

$1\frac{6}{12}=\frac{1*12+6}{12}=\frac{18}{12}\ pitchers\ of\ fruit\ juice$

$\frac{18}{12}-\frac{4}{12}=\frac{14}{12}\ pitchers\ of\ fruit\ juice$

convert to mixed number

$\frac{14}{12}=\frac{12}{12}+\frac{2}{12}=1\frac{1}{6}\ pitchers\ of\ fruit\ juice$

Solve for x.<br> z=(x-7)k

aliya0001 [1]

Answer:

$x=\frac{z}{k}+7$

Step-by-step explanation:

we have

$z=(x-7)k$

solve for x

That means ----> isolate the variable x

Divide by k both sides

$\frac{z}{k}=x-7$

Adds 7 both sides

$\frac{z}{k}+7=x$

Rewrite

$x=\frac{z}{k}+7$

I need help with this ASAP.

Tomtit [17]

Answer:

Step 1 write the equation for perimeter (2L+2W =24)

Step 2 write the equation for area L x W = 32

Step 3 rewrite the equation of area so that one variable is on the right side L=32/W

Step 4 substitute L from step 3 into Equation 1 and simplify 2(32/W)+2W=24

Step 5 having found the width in step 4, use equation 3 to find the length

Step-by-step explanation:

<em>This is just added to show you how to solve but limit your answer to the answer above: rate brainliest please</em>

Area = L*W

Perimeter = 2(L+W)

So say L*W=32

and 2(L+W) = 24 which is 2L+2W =24

From area L=32/W

Then substitute it into perimeter

2(32/W)+2W=24 if you simplify this you get Width is 4 and 8

then length =32/W but W is 4 and 8 So L= 8 and 4

Meaning you have two options first rectangle is W=4 and L is 8, second triangle W=8 and Length=4
