Equality Properties

Step-by-step explanation:

Step 1: Define Equation

2/3x = 27

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Answer:it would be 1:2

Answer:

1 : 2

Step-by-step explanation:

2 : 4

A ratio is another way of expressing a fraction. Hence, if one divides both sides by the same number, it will be the equivalent of one reducing a fraction, and it will still be equivalent to the original value. Hence, to reduce this ratio; divide both sides by 2

1 : 2

Answer:

About $43.69.

Step-by-step explanation:

1.65+0.42t=20 you minus the 3 minutes from the 23 minutes because those are paid for by the 1.65. Then for every extra minute, you pay 42 cents.

1.65+0.42t=20

Subtract the 1.65

0.42t=18.35

t≈43.69

Answer:

C = $30 + $15h

Step-by-step explanation:

Given that:

Hourly rate = $15

One time fee = x

Amount charged for an hour of service = $45

Hence,

One time fee + $15* 1 = $45

One time fee = $45 - $15

One time fee = $30

Hence, total charge C for h hours of landscaping:

Total charge = one time fee + (hourly charge * number of hours)

C = $30 + $15h

Answer:

I am gonna assume 4.

Step-by-step explanation:

As we can see the more people who rent out a lane, there are more people bowling.

The statement is best supported by the scatterplot is D. There is a positive linear association between the number of lanes rented and the number of people who bowl.

Suppose we're measuring something whose values are numeric. For each value of that thing we observe, we plot a dot above that value in the number line. Thus, the total number of dots in the dot plot tells us the total number of observations of the values of that thing.

Given that daily attendance at a bowling alley was recorded for 15 days.

The scatterplot represents the number of lanes rented each day and the number of people who bowled that day.  

By looking at the scatter plot graph we will have that there is a positive linear association between the number of lanes rented and the number of people who bowl.

Answer:

60/25 is greater than 60/132

Answer:

60/25

Step-by-step explanation:

Between the two, 60/25 most definitely would be the greater one of the two. Unless if you were intending 25/60, 60 divided by 25 gives you 2.4. 60/132 gives you 0.4545, so the 2.4 is greater.

Answer:

The LCM of 4 and 7 is 28

Step-by-step explanation:

LCM is the lowest common multiple of two or more numbers.

To find it do that:

Let us find the lowest common multiple of 4 and 7

→ List the multiples of 4

∵ The multiples of 4 are, 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, .......

→ List the multiples of 7

∵ The multiples of 7 are, 7, 14, 21, 28, 35, 42, 49, .........

→ Find the first common multiple of 4 and 7

∵ 28 is the first common multiple of 4 and 7

∴ The lowest common multiple of 4 and 7 is 28

∴ The LCM of 4 and 7 is 28

Answer:

x = 0, -4 and -3.

Step-by-step explanation:

The given expression is "3x to the power of 3 + 21x squared + 36x = 0".

We can write this expression as follows :

[tex]3x^3+21x^2+36x=0[/tex]

Taking 3x common.

[tex]3x(x^2+7x+12)=0\\\\3x=0\ \text{and}\ (x^2+7x+12)=0[/tex]

x = 3

[tex]x^2+7x+12=0\\\\x^2+3x+4x+12=0\\\\x(x+3)+4(x+3)=0\\\\(x+4)(x+3)=0\\\\x=-4,-3[/tex]

Hence, the solution of the given quadratic equation are x = 0, -4 and -3.

Answer:

x=2

length y = 4

angle Z = 45

Step-by-step explanation:

x^2 = 2x^2 - 4

put like terms on same sides, lets subtract x^2 to both sides

0 = x^2 - 4

add 4 to both sides

4 = x^2

square root of 4 = 2

x=2

since it is a square, we know all sides are the same length (proof also shown) so y is equal to the other side x^2

y = x^2

y = 4

Angle Z is 45 degrees, because a square has all right angles that are 90 degrees, but a diagonal evenly splits angle into two 45 degree parts.
