Answer:

26 students

Step-by-step explanation:

55 pieces given - 3 she keeps for herself=52

52÷2pieces each = 26

Answer:

-23

Step-by-step explanation:

Common difference = 2nd term - 1 st term

                                = -8 - (-3)

                                = -8 + 3

                               = -5

To get the next term add (-5) to the previous term

5th term = (-18) + ( (-5) = -23

Answer:

f(-12)=-18

Step-by-step explanation:

since we are replacing the x for -12 that means we will have the equation f(-12)=1/2(-12)-12 which would give us f(-12)=-6-12 which would equal -18 so the answer for f(-12) is -18

Answer:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

The ratio of girls to students is choice c, 34:72 because it said girls to students. We already know the total number of students and the number of boys, all we have to do now is subtract the total number of students to the number of boys to get the number of girls, 72 - 38 = 34......and that's it we put the number of girls then the number of students.

Answer:

25

Step-by-step explanation:

As it is stated, the two triangles are similar.

To find the distance across the river which is represented with d,

we can use the similarity ratio:

20/36 = d/45 cross multiply expressions

36d = 900 divide both by 36

d = 25

Answer:

2

Step-by-step explanation:

if you add 1 + 1 the solution would be 2.

Answer:

The answer is 2.

Step-by-step explanation:

1+1

1+1=2

If you add 1 and 1, it'll give you 2.

Answer:

4.25 + 2.50x < 25

Step-by-step explanation:

Note:

< →  Less than

> → Greater than

Manny can't spend more than $25 and you pay an initial fee of 4.25 for the shoes and 2.50 for each game so the inequality would be

[D] $4.25 + 2.50x < 25.

Step-by-step explanation:

Answer:

83/100

Step-by-step explanation:

0.83 = 83/100

Since 0.83 is a fraction of 100 (1.0) then it makes sense to turn 0.83 into 83/100.

Answer:

A. 6 dollars per week.

Step-by-step explanation:

Because if you look carefully in the graph, you would see that the dot on 1 week is above 5 dollars so therefore, it would be 6 dollars. To check, look at the next dot and see. You will see that the dot above 2 weeks is in the middle of 10 and 15 dollars.

Answer:

Some number divided by 4

Step-by-step explanation:

The y stands for an unknown number, aka some number. The slash indicates division, so it would be some number divided by 4.

Answer:

Step-by-step explanation:

Answer:

x= -4

Step-by-step explanation:

Step 1: Simplify

2x-3+3x=-23 turns into

5x-3=-21 -- combined like terms

Step 2: Start Solving

5x-3 = -23

+3         +3    -- Getting x alone by adding 3 to cancel it out

5x = -20

/5       /5    -- getting x alone by dividing by 5 to again cancel it out

Step 3: The answer

x = -4

Answere:

x=-4

Step-by-step explanation:

well, if you have the equation 2x-3+3x=-23, The first thing you wanna do is add up the X's so 2x+3x=5x, and then you put the 5x in the equation instead of 2x+3x:

-3+5x=-23

Then you since you have a -3, you should add 3 on BOTH sides of the equal sighn. And when you add 3 and -23 you get -20, so the new equation is:

5x=-20, from there you can tell X=-4

Tell me if you have any questions, and im sorry if the explaination is not thta good, I explain stuff better when i am face to face with someone, Have a good day!

Answer:

The sum of all positive integers is

5 + 6 + 7 + 8 + 9 + 10

              = 45

Step-by-step explanation:

Because [tex]\sqrt{24} = 4.89[/tex] and [tex]\sqrt{102} = 10.09[/tex]

So positive numbers between 4.9 and 10.09 are

 5+6+7+8+9+10 = 45

Answer:

nope ask your parents

Answer:

x int: -5

y int: -2

Step-by-step explanation:

Plug in 0 for x to find y intercept. 6(0) + 15y = -30 then you would get 15y = -30. Divide by 15 on both sides. y = -2

Plug in 0 for y to find x intercept 6x + 15(0) = -30 then you would get 6x = -30. Divide 6 on both sides. x = -5
