Solve this equation y=bd-6, for b

Answers

To solve this equation, you would need to isolate b. To do this, first you would add six to both sides. Then, to get rid of the d, you would divide both sides by d since that is the opposite of multiplication. So, the answer would be

b = y-6
———
d

Answer: [tex]b = \frac{y+6}{d}[/tex]

Step-by-step explanation: To isolate b, begin by adding 6 to both sides

y=bd-6

y + 6 = bd - 6 +6 This "cancels" 6 on the right leaving

y + 6 = bd Divide both sides by d

(y + 6)/d = bd/d This cancels d on the right leaving

(y + 6)/d = b To neaten this up rewrite (using the equations tool below)

[tex]b = \frac{y+6}{d}[/tex]

Who is able to type a minimum of 95 words every 2 minutes?

Answers

izzy because her word rate is 98, which is more than 95 (the minimum).

It is Izzy because for Remmy you cut 168 in half which is 84, so that isn’t enough. And for Justin, 1/3 of 135 is 45 and 45 + 45 = 90 so, that isn’t enough. So, it must be Izzy.

An art club sells 42 large candles and 56 small candles.
a. Write and simplify an expression that represents the profit.
expression for the profit: _(_-x)+_(_-y)
simplified expression for the profit: _______
b. A large candle costs $5, and a small candle costs $3. What is the club’s profit?
club's profit: $__

Answers

Answer:

Profit = $(700 - 42x - 56y)

Step-by-step explanation:

For large candles, the selling price is $10 and its making cost is $x.

So, by selling a large candle the profit is $(10 - x)

Again for small candles, the selling price is $5 and its making cost is $y.

So, by selling a small candle the profit is $(5 - y)

Therefore, in a sell of 42 large candles and 56 small candles the total profit will be, P = 42 (10 - x) + 56 (5 - y)

⇒ P = 420 - 42x + 280 - 56y {Applying distributive property}

⇒ P = $(700 - 42x - 56y) (Answer)

Step-by-step explanation:

Answer:

Matter is anything that takes up space. All matter (aka everything) is made up of atoms. The air that we breathe is matter because it is made up of mainly oxygen atoms, but also other atoms as well.

Answer:

Assuming the coordinates of the original image were (-5, 2), (2, 2), and (4, -3), then by dilating by two, it would be (-10, 4), (4, 4), and (8, -6)

Step-by-step explanation:

When dilating by a factor of n, you multiple both the x and y-coordinates by n, so -5*2 is -10 2*2 is 4, making the coordinate (-10, 4)
