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:

x=12

Beginning with an "If-then" statement ⇣

If 2/5 = 30 then 1/5 = 15

Now we have 1/5, let's make it 1 by multiplying x5.

15 x 5 = 75

Answer:

Step-by-step explanation:

its 38

After reducing the given number 40.00 by 5%, the reduced number is, 38

The percentage is a mathematical term, which means a number or a ratio which is represented in fractions of 100. We use the '%' symbol to represent the percentage.

Formula for percentage;

Percentage = (present quantity/whole quantity)×100

Given that,

The number, 40.00

After reducing it by 5% = ?

5  =  (x/40)×100

x = 2

5% of 40 is 2,

So subtracting it from 40

After decreasing it by 5%

The number = 40-2

                     = 38

Hence, the number is 38

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:

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

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:

C) Y > -7

Answer:

=> e° + f° = 180°

Step-by-step explanation:

we know. that this is a parallelogram .

e° + f° = 180° { because they are adjacent angle and the sum of adjacent angles in a parallelogram is 180°}

Answer:the answer is e° + f° = 180°

Step-by-step explanation:

I got it right

Answer:

x = 49°

Step-by-step explanation:

Hello! The sum of all angles in a triangle is 180°

64 + 67 = 131

180 - 131 will give you x

180 - 131 = 49° = x

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

Brainliest will be appreciated.

4/15 + 1/9 = 12/45 + 5/45 = 17/45

Your answer is: 2x^2+xy-21y^2

Step-by-step explanation:

Hope this helped : )

Answer:

x=3 /

steps: (For x)

Turn the equation into --> -x+1 = 2/3x-4

Next is the multiply the equation by 3 to make isolating x easier so it becomes --> -3x+3=2x-12

Now arrange the terms to where variables are on a side and constants are on a side

it should look like --> -3×-2x=-12-3

Now combine like terms --> -5x=-15

finally just divide by -5 on both sides

x=3

For y:

substitute X for either of the equations

y=2/3 x 3-4

y=-2

The solution is (3,-2)

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
