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

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:

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:

Zeros are x = 1.5, -2.5

Step-by-step explanation:

Given function is,

F(x) = 4x² + 4x - 15

      = 4(x² + x - 3.75) [Since, intercept form of a quadratic equation is the factored form of the function]

F(x) = 4(x² + 2.5x - 1.5x - 3.75)

      = 4[x(x + 2.5) - 1.5(x + 2.5)]

      = 4(x - 1.5)(x + 2.5)

For 'x' intercepts,

f(x) = 0

4(x - 1.5)(x + 2.5) = 0

x = 1.5, -2.5

Therefore, zeros of the given function are x = 1.5, -2.5.

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!

Step-by-step explanation:

Answer:

a) 11 months

b) 788 discs

Step-by-step explanation:

Let us represent number of months = x

For DVD's

The number of DVD's sold at Fry's Electronics in a month was 920 and the number of DVD's sold decreased by 12 per month.

Hence:

920 - 12x

For Blu ray

The number of Blu-ray discs sold at Fry's Electronics in the same month was 502 and the number of Blu-ray discs sold increased by 26 per month.

502 + 26x

Write a system of equations to model th situation.

a).If this trend continues, in how many months will the number of DVD's sold each month equal the number of Blu-ray discs sold each month?

To solve this:

DVD's = Blu-ray

920 - 12x = 502 + 26x

Collect like terms

920 - 502 = 26x + 12x

418 = 38x

x = 418/38

x = 11 months

b) How many each disc is sold in that month?

For DVD's

920 - 12x

x = 11

Hence:

920 - 12 × 11

= 920 - 132

= 788 discs

For Blu ray

= 502 + 26x

x = 11

Hence:

= 502 + 26x

= 502 + 26 × 11

= 788 discs

Therefore, 788 discs were sold in each month

Answer:

Hannah sold 4

Kiera sold 6

Total Subscriptions = 10

Step-by-step explanation:

K = number of Kiera subscriptions

H = number of Hannah subscriptions

T = hours

6+K = 4+2H

K = 2H-2

K+H = 10

K= 10-H

substitute for K

2H-2 = 10-H

3H = 12

H = 4

K = 6
