Simplify
– 23 – 2y – 2z + 5x – 2y – 4z

Answer:

Step-by-step explanation:

Let the number be 'x'

Half a number = [tex]\frac{1}{2}x[/tex]

Half a number increased by the quotient of p and t

[tex]\frac{1}{2}x+\frac{p}{t}[/tex]

[tex] \implies \sf \boxed{ \sf7.71}[/tex]

The remainder is 5 when 54 is divided by 7.

Division in mathematics is the process of dividing an amount into equal parts. For instance, we may split a group of 20 people into four groups of 5, five groups of 4, and so on.

Given:

We have to divide 54 by 7.

So, the division is

                            7 | 54 | 7

                                  49

                              -_____

                                     5

Then, the remainder is 5 because we do not have number further and 5 is smaller than divisor.

#SPJ5

Answer:

largest ∡ = 81°

Step-by-step explanation:

44 + 3x - 11 + 4x - 7 = 180

7x + 26 = 180

7x = 154

x = 22

4(22)-7 = 81

Answer:

B

Step-by-step explanation:

Remark

I'm not sure why (f + g)x is there at all. All you are instructed to do is add the two given functions together.

Solution

(f+g)y = 5x^2 - 2y + 1 - 3y^2 - y - 2

(f+g)y = 2y^2 - 3y - 1

That's B

Answer:

y = 9°

Step-by-step explanation:

Vertical Angles law

63° = 11y - 36

63+36 = 99

11y = 99

y = 9

The two dot plots are missing, so i have attached it.

Answer:

The mean at the beginning of the school year was 9.5 miles and the mean at the end of the school year was 10.2 miles

Step-by-step explanation:

From the attached image, we are told to compare the means for each plot to the nearest tenth.

Mean = Σx/n

Now, from the image, total number of miles run by the 14 students at the beginning of the school year is;

(1 × 7) + (2 × 8) + (4 × 9) + (4 × 10) + (2 × 11) + (1 × 12) = 133

Mean of miles run at the beginning of the school year = 133/14 = 9.5 miles

Again, from the table, total miles run at the end of the school year = (2 × 8) + (2 × 9) + (4 × 10) + (3 × 11) + (3 × 12) = 143

Mean of miles run at the end of the school year = 143/14 = 10.2 miles

Thus;

The mean at the beginning of the school year was 9.5 miles and the mean at the end of the school year was 10.2 miles

Step-by-step explanation:

Positive in division means either both numbers are positive or negative

Answer:

4

Step-by-step explanation:

30*4=120 because 12=3*4 and 30*4 is basically 3*4*10, and since it's asking for the scale factor, we test to see if 12*4=48, which it does.

Answer:

Number of week they have same amount = 4 week

Step-by-step explanation:

Given:

Amount Joe have = $14

Joe's saving per week = $10

Amount Josh have = $26

Josh saving per week = $7

Find:

Number of week they have same amount

Assume;

Number of week they have same amount = a

So,

(14 + 10a) = (26 + 7a)

3a = 12

a = 4

So,

Number of week they have same amount = 4 week

Answer:

A

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

1. P(E)>P(D) (Event E is more likely to occur, therefore it has a greater probability)

2. P(E)>0.5 (The probability of event D is given as 0.5, so rewrite P(D) in the inequality)

3. 0.5 is equal to 0.5 and 0.1 is less than 0.5, so you can rule out options A and D

4. This leaves us with options 1.5 and 0.9, but it is impossible to have a probability that is greater than equal to one, so you can immediately rule out B

5. After this elimination process, the only remaining answer is C) P(E)=0.9

Answer:

y = 1/2x + 1

Step-by-step explanation:

The slope is the change in y over the change in x. The line goes down one and two left, making the slope 1/2.

The line crosses the y axis at positive  1 and that is the y-intercept.

You just literally mark the graph, you see the 1st points (2,12) go on the X axis to 2, then go up to 12 and mark that as a point. and continue with this tactic with the rest.

Answer:

√{99×33×3}=√{33×3×33×3}=√(33²×3²)=±33×3=±99

Answer:

99

Step-by-step explanation:

Cause 33×3=99 ,and the function of the root is to get the number that we multiply it ti itself

For example [tex]\sqrt{4}[/tex] =2 cause 2×2=4 ,so[tex]\sqrt{2*2}[/tex] =[tex]\sqrt{4}[/tex] which is =2

so [tex]\sqrt{99^{2} }[/tex] =99
