Which of the following are like terms


y and -3y


2x2 and 3x3


k4 and 8k4


2x and x

Answer:

its b as the variables have no values

Answer:

B.

Step-by-step explanation:

If you calculate the sum of both you get:

5x + 2x + 4y - 7y = 24 + 26

7x - 3y = 50, which is B

Answer:

A= 16 B=28

Step-by-step explanation:

So the ration is 4:7, you have to find multiples that have that same ratio

Multiply both numbers by 4, this should get you

16:28

16 + 28 = 44

Therefore this is the correct answer

Answer:

4

Step-by-step explanation:

Answer:

p + m - 10 is your expression

Step-by-step explanation:

Answer:

p + m - 10

Step-by-step explanation:

Hi , expressions are easy you just need to know how to read these weird word problems they give us.

Let us look at some key words and change them into symbols and not words.

10 less

This means it will most likely be a -10 somewhere

The sum of p and m

This would mean addition, so p + m

With this info we can form an expression.

p + m - 10

This is how I would write it.

Since the sum of p and m is (p+m) and the 10 less is the (-10)

You would add the p and m to find their sum and then take off 10 for the 10 less.

I hope this helps!

Answer:

No element is common to all the sets

AnBnc = { }

Step-by-step explanation:

If A= {x: xis a factor of 72}

A = {2, 3, 4, 6, 8, 9, 12, 18, 36, 72}

If B= {x: 72x+3<2x-3).

72x+3 <2x-3

72x - 2x < -3-3

70x < -6

x < -6/70

x < -3/35

x< -0.0857

If

C= {x:x<20}

C = {-∞, 19}

The intersection of the sets AnBnc = {} i.e an empty set

Note that intersection means all the elements common to the three sets

Answer:

y= -1

Step-by-step explanation:

Answer:

The answer would be y= -1

Step-by-step explanation:

When we have a number outside the parenthesis we do the rainbow method where we multiply the number on the outside of the parenthesis to the numbers inside the parenthesis so

-4*y= -4y and -4*-2=8

-4y+8=12

-4y=4

y=-1

Answer:the example equation becomes "x + 10 - 15x = 20," which is then "-14 x + 10 = 20." Subtract 10 from each side, divide by 14 and you have end up with x = -10/14, which simplifies to x = -5/7. Plug in the x value in to the first equation to find out the y value.

Step-by-step explanation:

Answer:

x=9

y=14

Step-by-step explanation:

Your picture shows that the two angles are congruent so:

2[(2x+27)]=90

4x+54=90

4x=36

x=9

Your picture shows the two horizontal lines as congruent also so:

4y-19=y+23

4y-19+19=y-y+23+19

3y=42

y=14

Answer:

$7

Step-by-step explanation:

I ordered 4 new CD's by mail. Each CD costs the same amount and there was an additional $5 shipping charge that brought the total to $33. Write and solve the equation to find the cost of one CD.

Let us represent the cost of 1CD = x

Total cost = $5 + 4x

= 5 + 4x

Total cost = $33

Hence, our Equation is given as:

33 = 5 + 4x

4x = 33 - 5

4x = 28

x= 28/4

x = $7

The cost of 1 CD = $7

Step-by-step explanation:

c=144°(vertically opposite angle)

b+c=180°(straight angle)

b+144=180

b=180-144

b=36°

Answer:

she listed the multiples of 15, not the factors. The factors would be 1, 3, 5, 15.

Step-by-step explanation:

Answer:

1 ÷ 11

Step-by-step explanation:

The computation is shown below:

let us assume the yellow cubes be x

So, blue cubes be 2x

And, green cubes be 2x (4) 8x

Now the ratio is

Yellow: Blue: green

x:2x:8x

1:2:8

Now the probability of yellow cubes is

= 1 ÷ (1 + 2 + 8)

= 1 ÷ 11

Answer:

[tex]175[/tex] meter is  difference in height between the submarine and the aircraft

Step-by-step explanation:

The height of aircraft above the surface [tex]= 150[/tex] meter

Depth at which the submarine lies below the surface [tex]= 25[/tex] meter

Depth at which the underwater robotic vehicle  below the surface [tex]= 186[/tex] meter

Difference in height between the submarine and aircraft is equal to

[tex]25 +150 = 175[/tex] meter

Answer: No solution because both the y and x cancel each other out so it would be 0=12

Answer:

Step-by-step explanation:

4 not equal to 2

Answer: 7ft

Step-by-step explanation:

The shape is a trapezium

Area of Trapezium= (1/2)(a+b)(h)

Area of Trapezium= 40sqft

a= x

b= 9ft

h= 5ft

40= (1/2)(x+9)(5)

40= (5(x+9)/2)

Cross multiply

80= 5(x+9)

80= 5x + 45

5x= 80-45

5x= 35

Divide both sides by 5

x= 7

Answer:

l = 40 m and b = 30 m

Step-by-step explanation:

Let the length and breadth of a rectangle be 4x and 3x.

We know that,

The perimeter of a rectangle is given by :

P = 2(l+b)

140 = 2(4x+3x)

70 = 7x

x = 10

Length, l = 4x = 4(10) = 40 m

Breadth, b = 3x= 3(10) = 30 m

So, the length and breadth of a rectangle are 40 m and 30 m respectively.

Answer:

All of the above.

Step-by-step explanation:

By looking at the graph and taking point x at 4 and y at around 300. This shows us the precise rate of the graph which is when x = 4, y is equal to 300.

Now if we substitute the x as 4 in any of the equations we will get values larger than 300. Therefore, all the equations have a greater rate of change.

y = 85(4) = 340 (Greater)

y = 50(4) + 150 = 350 (Greater)

y = 65(4) + 100 = 360 (Greater)

Given:

The inequality is

[tex]3|p+4|+5<8[/tex]

To find:

The solution set for the given inequality.

Solution:

We have,

[tex]3|p+4|+5<8[/tex]

[tex]3|p+4|<8-5[/tex]

[tex]3|p+4|<3[/tex]

Divide both sides by 3.

[tex]|p+4|<1[/tex]

It can be written as

[tex]-1<p+4<1[/tex]

Subtracting 4 from each side, we get

[tex]-1-4<p+4-4<1-4[/tex]

[tex]-5<p<-3[/tex]

The solution set of the given inequality is (-5,-3).

Therefore, the correct option is A.

Answer:

m = 8

n = 9

Step-by-step explanation:

Remark

By similar triangles

(m - 4) /8 = 8 / 2m             Cross multiply

2m(m - 4) = 64                  Expand the left

2m^2 - 8m = 64                Divide through by 2

m^2 - 4m = 32                   Subtract 32 from both sides.

m^2 - 4m - 32 = 0             Factor

(m - 8)(m + 4) = 0

m + 4 has no meaning in geometry. - numbers cannot be distances.

m - 8 = 0

m = 8

===================

By the same kind of similar triangles used in problem A we get

7 / x = x / 9

x^2 = 63

Just leave this as it is. We'll solve this by the Pythagorean Theorem.

x^2 + 9^2 = (n + 3)^2

63 + 81 = (n + 3)^2

144 = (n + 3)^2                   Take the square root of both sides

12 = n + 3                           Subtract 3 from both sides.

9 = n

Answer: 2¹/₃ hours per week

Step-by-step explanation:

Bryce practices his piano for 1/3 hours each day.

The number of days in a week is 7 days so to find out the number of hours he practices per week, multiply the number of hours practiced per day by 7.

= 1 /3 * 7

= 7 / 3

= 2¹/₃ hours per week
