Answer:

The first step is Add 6 to both sides

Step-by-step explanation:

we have

\frac{2}{5}x-6=-16

Solve for x

That means ----> isolate the variable x

step 1

Adds 6 both sides

\frac{2}{5}x-6+6=-16+6

\frac{2}{5}x=-10

step 2

Multiply by 5/2 both sides

\frac{2}{5}x(\frac{5}{2})=-10(\frac{5}{2})

x=-25

therefore

The first step is Add 6 to both sides

Answer:

The new volume is 14,850cm³

Step-by-step explanation:

Given

Volume of a rectangular prism = 550cm

Required

Value of volume when the dimensions are tripled.

The volume of a rectangular prism is calculated using the following formula.

V = lbh

<em>When Volume = 550, the formula is written as follows</em>

550 = lbh

<em>Rearrange</em>

lbh = 550

However, when each dimension is tripled.

This means that,

new length = 3 * old length

new breadth = 3 * old breadth

new height = 3 * old height

<em>Let L, B and H represent the new length, new breadth and new height respectively</em>

In other words,

L = 3l

B = 3b

H = 3h

Calculating new volume

New volume = LBH

Substitute, 3l for L, 3b for B and 3h for H;

V = 3l * 3b * 3h

V = 3 * l * 3 * b * 3 * h

V = 3 * 3 * 3 * l*b*h

V = 27 * lbh

Recall that lbh = 550

So,

V = 27 * 550

V = 14,850

Hence, the new volume is 14,850cm³

Answer:

3/4 is the slope

Step-by-step explanation:

slope= mx+b

so,

(10,30) is an exact meet

so is (50,60)

so what is the rise/run

answer

30/40

or

3/4

so mx+b=

3/4x+22

full equation is 3/4x+22

Natalija [7]

Answer: you have $31 at the end of the week

Step-by-step explanation:

First, let's put this problem into an algebraic expression. We started off with $42. We then added $25 and took out $36 during the week. The expression for this problem is

42

+

25

−

36

.

Next, add 42 and 25 together to get

67

. We now have

67

−

36

.

Finally, subtract 36 from 67 to get

31

, our answer.

Urn I contains 2 red balls and 2 white balls. Urn II contains 13 white balls. A ball is selected at random from urn I and placed
beks73 [17]
15/17 Because there is a 13/13 chance but then you put a ball in from Urn 1 and that is 2/4. Also, 13/13 plus 2/4 = 15/17
