69 plus 13 because 30 plus 13 is 43, 43 plus 13 is 56, and you know the rest

0.95 because it adds 0.13 each time

$\qquad\qquad\huge\underline{\boxed{\sf Answer☂}}$

Let's solve ~

$\qquad \sf \dashrightarrow \: 2m - 3 - 5 = - m + 10$

$\qquad \sf \dashrightarrow \: 2m + m = 10 + 3 + 5$

$\qquad \sf \dashrightarrow \: 3m = 18$

$\qquad \sf \dashrightarrow \: m = 18 \div 3$

$\qquad \sf \dashrightarrow \: m = 6$

Hence, value of m is 6

Ray wants to buy the larger of two aquariums. one aquarium has a base that is 20 inches by 20 inches and height that is 18 inche

Svetradugi [14.3K]

Ray should buy the first one because it has the greater volume by 1,440 square inches.
Tank 1: 20x20x18=7,200
Tank 2: 40x12x12=5,760
7,200-5,760=1,440

<h3>Answer: HF = 5</h3>

=============================================

Explanation:

Refer to the diagram below. I'm adding in points A and B, which are marked in blue. I'm also adding in variables x, y, and z.

The goal is to find HF, so let's make that equal to x. This is also equal to HB because they are radii of the same circle.

Let y be the length of segments JA and JB.

Let z be the length of segments CF and CA.

So in short we have

x = HF = HB
y = JA = JB
z = CF = CA

We know that

CH = 13
HJ = 19
CJ = 22

This must mean

CH = CF+HF = z+x = 13
HJ = HB+JB = x+y = 19
CJ = CA+JA = z+y = 22

Or in short,

z+x = 13
x+y = 19
z+y = 22

Let's solve the first equation for z to get z = -x+13. I subtracted x from both sides.

Now plug this into the third equation to get

z+y = 22

(z) + y = 22

(-x+13) + y = 22 ... replace z with -x+13

-x+13+y = 22

-x+y+13 = 22

-x+y = 22-13 .... subtract 13 from both sides

-x+y = 9

------------------------------------

So we have this reduced system of equations of two variables and two equations

x+y = 19 ... found earlier
-x+y = 9 .... what we just found above

Add the equations straight down. This is the elimination property.

Doing so leads to the x terms canceling out since x + (-x) = 0x = 0

The y terms add to y+y = 2y

The terms on the right hand side add to 19+9 = 28

We are left with 2y = 28 which solves to y = 28/2 = 14.

If y = 14, then,

x+y = 19

x+14 = 19

x = 19-14

x = 5

In which we can then say

z = -x+13

z = -5+13

z = 8

Though we don't need to find z (unless you're curious about it).

Since x = 5, and we set HF equal to x, this means that HF = 5.

What is the common denominator of StartFraction 1 Over a EndFraction StartFraction 1 Over b EndFraction in the complex fraction

stepladder [879]

The common denominator is 1

Given the expression:

$\frac{1/a-1/b}{1/a1/b}$

Find the LCM of the numerator to have:

$\dfrac{\frac{b-a}{ab} }{\frac{1}{a} \frac{1}{b} }$

Simplify both the numerator and the denominator to have:

$= \dfrac{\frac{b-a}{ab} }{\frac{1}{ab} }\\= \frac{b-a}{ab} \times ab\\=\frac{b-a}{1} \times 1 \\=\frac{b-a}{1}$

From the result, we can see that the common denominator is 1
