Answer:

Step-by-step explanation:

1) Angle 1 and angle 2 are complementary angles. If angle 1 measures (3x + 2), what is the measure of angle 2? 3x+2 + y = 90

2) Angle A and angle b are supplementary angles. Angle A measures (2m – 10) degrees and angle b measures (m + 25) degrees. Find the measure of angle A and angle b.

3) Three angles are supplementary angles. If one angle measures 25 degrees, the second angle measures m + 15. The third angle measures 2m degrees. What is the value of m?

You received a ​$100 gift certificate to a clothing store. The store sells​ T-shirts for ​$12 and dress shirts for ​$21. You wan
Kay [80]

Answer:

3 dress shirts and 3 T-shirts

4 dress shirts and 1 T-shirt

Step-by-step explanation:

You must spend at least $93 and no more than $100.

2 dress shirts: $42 + 5 T-shirts: $60 = $102 too much money

2 dress shirts: $42 + 4 T-shirts: $48 = $90 too much money left

3 dress shirts: $63 + 3 T-shirts: $36 = $99 this works

4 dress shirts: $84 + 1 T-shirt: $12 = $96 this works

5 dress shirts: $105 too much money

Answer:

3 dress shirts and 3 T-shirts

4 dress shirts and 1 T-shirt

What’s the definition of input and output?
Vika [28.1K]

Input is the same as the x-term and output is the same as the y-term.

For example, take a look at the image provided with thee table.

Looking at the first box of our table, notice that if we subtract 5 from 1, we get -4 and if we subtract 5 from 2 we get -3 and if we subtract 5 from 3, we get -2.  Notice that in each case, we're subtracting 5 from the input to get the output.

I attached a table so you can practice if you'd like to. All you have to do is subtract 5 from each input and you will end up with the output. The first few are done for you. I also provided an answer key in the next image so you can check your work.

The last one might be a little trick. In the input, we have n which is a variable that represents any number. If we want to find the nth term, we simply subtract 5. So we have n - 5.

First image is practice if you'd like and the second is the key.

If you don't want to do it, no worries.

Last week f40 fifth graders went on a field trip to the science museum
Xelga [282]
8 out of 40 fifth graders went to see the lab animal presentation. This can be written as this expression:

\frac{8}{40}

Find the greatest common factor of 8 and 40:

Factors of 8: 1, 2, 4, 8
Factors of 40: 1, 2, 4, 5, 8, 10, 20, 40

Therefore the greatest common factor is 8. Divide both the numerator and the denominator by 8.

\frac{8}{40} = \frac{8/8}{40/8} = \frac{1}{5}

Therefore the fractional part is \frac{1}{5}.

To get the percentage, you need to get the denominator to a value of 100.

To do so, you need to find the value to multiply both the numerator and denominator by to achieve this.

To get this value, you can divide 100 by the denominator of the fractional value.

100 / 5 = 20

Then you can multiply both the numerator and denominator by 20:

\frac{1}{5} = \frac{1 * 20}{5 * 20} = \frac{20}{100}

From here, the numerator will state the percentage:

20\%

Hope this helps :)
