don't stress about it because you can do this! just sit down in a quiet room and try your best your only in 7th grade so even if you don't get everything done it won't effect you moving forwards too much and try talking to someone about falling behind like a trusted adult or teacher they might be able to help you come up with a game plan for the future

Hope This Helps And I Wish You Luck!

Answer:

Hmm similarly my sister and I, who are both in school, have the same issue. Some tips that I use myself are, listening to music without words in the background. This helps me calm down and releases stresses, as well as calming scents if you have any like lavender. Try to stretch every so often, this helps gain energy and let blood flow through your veins to your brain. Try listing your assignments you need to get done for the week and when you get done with one, cross it out. This makes me feel so much more accomplished and then I can tackle the assingments I am behind on. Also drink LOTS of water! This helps your WHOLE body!

Remember that these don't work for everyone and if you need anything else I can try to give you some more help! Try not to stress too much, believe me that is definitely a lot easier said than done! As long as you try your best and work towards your goal, that's what matters. Life is about your journey, not your destination. Try to stay positive! Not everything is going to be easy, but you can do it!

Answer:

Base (x) = 2

Step-by-step explanation:

First we know that to find the area you do:

Area=Base x Height

So plug in the 22 as the area and the 11 as the height so it looks like this:

22 = (x) x 11

Then to find x all you have to do is divide 22 by 11 in order to get x by itself:

22/11 = x

So your answer is 2

13 and 7.

Steps

x + x = 20

x - x = 6

2x = 26

x = 13

x = 20 - 13

x = 7

Answer:

13 and 7

Step-by-step explanation:

We have two unknown numbers that add up to 20 and subtract to 6. The question is asking us to find out these two hidden numbers.

Let's form two equations.

x + y = 20

and

x - y = 6

Since we have a positive y and negative y, we can use the addition method to these systems of equations.

   x + y = 20

   x - y = 6

+-----------------

2x = 26

Now isolate x to get x.

Divide both sides by 2 :

x = 13

Now that we have x, we can plug it into the equations.

13 + y = 20

13 - y = 20

So what number will make this true. Use the backwards method :

20 - 13 = 7

Therefore, 13 and 7 are our two numbers.

Answer:

a) 11x^5

b) 4 1/2mn

Step-by-step explanation:

Según los subrayados de las preguntas, creo que solo necesita ayuda en a y b. (Disculpe también mi español, no es mi lengua materna.) Entonces, para el primero, ya que ambos tienen el mismo exponente, todo lo que necesita hacer es restar los números. Como resta un negativo, el resultado es positivo, lo que significa que en su lugar agrega el número (sin el negativo)

Para el segundo, debes restar la fracción del número entero. Esto entonces su ecuación es 5- 1/2 que es 4 1/2mn. Entonces tu respuesta es 4 1/2mn

Answer:

SA = 126 square cm

Step-by-step explanation:

SA = 2(l · w) + 2(h · w) + 2(l · h)

SA = 2(5 · 6) + 2(6 · 3) + 2(5 · 3)

SA = 60 + 36 + 30

SA = 126 sq cm  

The surface area of the cuboid box is S = 126 cm²

What is the surface area of cuboid?

A cuboid is defined as a three-dimensional shape, that has six rectangular faces, eight vertices and twelve edges

The total surface area of the cuboid is given by the formula

Surface Area = 2 ( LH + LW + HW )

where ,

Length of the cuboid = L

Width of the cuboid = W

Height of the cuboid = H

Given data ,

Let the surface area of cuboid be S

Length of the cuboid = L = 6 cm

Width of the cuboid = W = 5 cm

Height of the cuboid = H = 3 cm

On simplifying , we get

Surface Area = 2 ( LH + LW + HW )

S = 2 ( ( 6 x 5 ) + ( 6 x 3 ) + ( 5 x 3 ) )

S = 2 ( 30 + 18 + 15 )

S = 2 ( 63 )

S = 126 cm²

Hence , the surface area is S = 126 cm²

Answer:

14.2 cm

Step-by-step explanation:

The hypotenuse of a triangle is measured using the pythagorean theorem. This formula sums up the squares of both legs of the triangle which would give the squared value of the hypotenuse. Therefore, we can then square root that value to find the hypotenuse. This would be the following...

[tex]9^{2} + 11^{2} = x^{2}[/tex]

81 + 121 = [tex]x^{2}[/tex]

202 = [tex]x^{2}[/tex]

14.21 = [tex]x^{2}[/tex]

Finally, we can see that the value of the hypotenuse is 14.2 cm

Answer:

4(x+4)

Step-by-step explanation:

Find to GCF of 4x+16.

Now factor out the GCF by dividing each term in the expression by 4.

4x divided by the GCF is x, and 16 divided by the GCF is 4.

The equivalent expression is 4(x+4).

Answer:

1.22 is the price of the shampoo after sales tax

Answer: X = -4

Step-by-step explanation:

90 - 5x + 62 -2x = 180

152 - 7x = 180

-7x = 28

x = -4

Check your answer by pluging in the vaule of x

90 - 5(-4)

90 + 20 = 110

62 - 2(-4)

62 + 8 = 70

110 + 70 = 180

Checks out.

Answer: 110 degrees and 70 degrees

Step-by-step explanation:

These angles are same side (of the traversal line) interior (inside the parallel lines) angles. Same side interior angles sum to 180 degrees. Add the two angles together and set them equal to 180. (90-5x) + (62-2x) = 180

Combine like terms. 90+62= 152 and -5x + -2x = -7x rewrite the equation as 152 + -7x = 180

Subtract 152 from both sides of the equation.

-7x = 28. Now isolate x by dividing both sides by -7. X= -4. Now we can substitute -4 back into the original equations. 90 -5(-4) = 90 +20 = 110 and 62 - 2(-4) = 62 + 8 = 70

We can double check our work to see if these two indeed add up to 180. 110 + 70 = 180
