76-2m<11+3m
76-2m-3m<11+3m-3m
76-76-5m<11-76
-5m/-5<-65/-5
when you multiply or divide by a negative number you have to switch the sign.
m>13
(I didn't have a greater than equal to sign so I just used a greater than sign)

The two toy store owners agree to specialize and to trade 30 puzzles for 10 puppets. The terms of trade are still 3 puzzles for

likoan [24]

Based on the exchange rate, at the end of the trade, Lewis will have 31 puppets and 2 puzzles left over while Geppeto will have 158 puzzles and 4 puppets left over.

<h3>What is the exchange rate of puzzles for puppets?</h3>

The exchange rate of puzzles for puppets is 3 to 1.

Geppeto has 20 puppets to exchange for puzzles.

Lewis has 50 puzzles to exchange for puppets.

Number of times Lewis can exchange puzzles for puppets = 50/3 = 16 times.

Lewis will get 16 puppets in exchange for 48 puzzles.

Therefore;

Lewis will have 16 + 25 puppets = 31 puppets and 2 puzzles left over

Geppeto will have 48 + 100 puzzles = 158 puzzles and 4 puppets left over.

in conclusion, the exchange rate determines the how many puzzles and puppets will each one have after they complete their trade.

Write the linear equation in slope intercept form 2x+By=16

allochka39001 [22]

Answer:

Part 1) $y=-\frac{2x}{B}x+\frac{16}{B}$

Part 2) $y=-\frac{1}{4}x+2$

Step-by-step explanation:

Part 1)

we know that

The equation of the line in slope intercept form is equal to

$y=mx+b$

we have

$2x+By=16$

Isolate the variable y

subtract 2x both sides

$By=-2x+16$

Divide by B both sides

$y=-\frac{2x}{B}x+\frac{16}{B}$

Part 2)

we know that

The equation of the line in slope intercept form is equal to

$y=mx+b$

we have

$2x+8y=16$

Isolate the variable y

subtract 2x both sides

$8y=-2x+16$

Divide by 8 both sides

$y=-\frac{2x}{8}x+\frac{16}{8}$

Simplify

$y=-\frac{1}{4}x+2$

Its pretty easy if you are good at math! Please help!

aleksley [76]

Step-by-step explanation:

Explanation:

The trick is to know about the basic idea of sequences and series and also knowing how i cycles.

The powers of i will result in either: i, −1, −i, or 1.

We can regroup i+i2+i3+⋯+i258+i259 into these categories.

We know that i=i5=i9 and so on. The same goes for the other powers of i.

So:

i+i2+i3+⋯+i258+i259

=(i+i5+⋯+i257)+(i2+i6+⋯+i258)+(i3+i7+⋯+i259)+(i4+i8+⋯+i256)

We know that within each of these groups, every term is the same, so we are just counting how much of these are repeating.

=65(i)+65(i2)+65(i3)+64(i4)

From here on out, it's pretty simple. You just evaluate the expression:

=65(i)+65(−1)+65(−i)+64(1)

=65i−65−65i+64

=−65+64

=−1

So,

i+i2+i3+⋯+i258+i259=-1

The length of a rectangle is 8 inches more than three times the width. the perimeter is 88 inches. find the length and width.

Sav [38]

We can say L as length and W as the width

L= 3w + 8

The formula for perimeter is 2L + 2W = P. We can substitute L in as "3w+8" to make the equation...

2(3w+8)+2w=88 Now, we can simplify by distributing the 2 to each term
6w+16+2w=88
8w+16=88 Then subtract 16 from each side..
8w=72
w=9

So the width is 9, so we can substitue that into the previous equation, L = 3w+8.

L=3(9)+8
L=27+8
L=35, W=9
