Answer:

26, 28

Step-by-step explanation:

2n , 2n + 2

2n + 2n + 2 = 54

4n + 2 = 54

4n = 52

n = 13

2n = 26

2n + 2 = 28

Answer:

Step-by-step explanation:

The sum of two consecutive even numbers is 54 find the answer

(54 - 2) : 2 = 26

26 + 2 = 28

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

check

26 + 28 = 54

Answer:

6400

Step-by-step explanation:

Substitute the given value into the expression

p²q²

= 10² × 8²

= 100 × 64

= 6400

Step-by-step explanation:

given that p=10

you would times 10 by itself so:

10x10=100

now the same for the q=8

8x8=64

now i think you would have to times 100 with 64 if not than there's your answer

which equals to 6400 (if you times it)

hope that helps

Answer-

Not quite sure what your asking but the if I understood correctly the answer is -122z+56

Answer:

−112z+56

Step-by-step explanation:

−56z+28−56z+28

Combine −56z and −56z to get −112z.

−112z+28+28

Add 28 and 28 to get 56.

−112z+56

Answer:

3.5

Step-by-step explanation:

The tenths place would be 0.1

So in 3.468 the 4 is in the tenths place

Look at the number to the right of it, if it is greater than 5 you round up and if it is 4 or lower you stay the same.

For 3.468 you would round up

So you would have 3.5

Answer:

c

Step-by-step explanation:

S=B+1/2Pl

-b from both sides

s-b=1/2Pl

x2 to both sides

2(S-B)=Pl

divide both sides by l

you get c

[33] x = 140° & y = 118°

    The lines are parallel, sso we can tell that y will equal 118° degrees because of corresponding angles. Then for x, we can add the non-adjacent angles together, 118° + 22° = 140°

[35] x = 26° & y = 64°

    x will be 180° - 90° - 64° = 26° because a triangle's angles are equal to 180° and the box represents a 90° angle. y is equal to 64° because the lines are parallel, and if we "flip" one of the triangles around we can see that y and 64° are corresponding angles. (to check, we add 26° + 64° + 90°, and it does equal 180°!)

Answer:

15.62500

Step-by-step explanation:

Answer:

62.5 62 1/2

Step-by-step explanation:

You need to convert the decimal into a fraction

which is 25/2 then make the bottom into the same

5/4 is good because it is 4 so change the 25/2 into a 4.

So you have to do 25x 2 and 2x2 equal to  50/4

then do it like normal

50/4 x 5/4=  250/4 62.5

(50 x 5 and 4x4

Step-by-step explanation:

Answer: 12 students

Step-by-step explanation:

Let X and Y stand for the number of students in each respective class.

We know:

X/Y = 2/5, and

Y = X+24

We want to find the number of students, x, that when transferred from Y to X, will make the classes equal in size. We can express this as:

(Y-x)/(X+x) = 1

---

We can rearrange X/Y = 2/5 to:

X = 2Y/5

The use this value of X in the second equation:

Y = X+24

Y =2Y/5+24

5Y = 2Y + 120

3Y = 120

Y = 40

Since Y = X+24

40 = X + 24

X = 16

--

Now we want x, the number of students transferring from Class Y to Class X, to be a value such that X = Y:

(Y-x)=(X+x)

(40-x)=(16+x)

24 = 2x

x = 12

12 students must transfer to the more difficult, very early morning, class.

Step-by-step explanation:

it just means to convert these equations into function definitions.

and a function looks like

y = ... something with x, factors, other functions, constants

1)

x + y = z

y = -x + z or z - x

2)

x - y = z

x - z = y or y = x - z

3)

x × y = z

y = z/x

4)

x/y = z

x = z × y

x/z = y or y = x/z

Answer:

Step-by-step explanation:

3/5 = 0.6

0.6> 0.2

1/2 = 0.5

0.5 > 0.35

2/10 = 0.2

0.2 > 0.152

The answer is

1.1%, 0.1, 1/9, 2/11

Step-by-step explanation:

convert the fractions to decimals, the percentage to decimal.

then just order the numbers from smallest to biggest

1/9= 0.11

2/11=0.18

1.1%/100= 0.011
