Answer:

for the third one 2/5 for the fourth one 3/5

Step-by-step explanation:

For the first one, I put 10/25 as a fraction and found the least common multiple, which is 5. I then simplified, and got 2/5.

For the second one, I chose 3/5 because there are 3 friends whose names end in a, and 5 friends whose names do not end in a. My theory was that I took the friends and divided them into 2 groups by most common.

hope this helps if it doesn't I will correct myself :)

Step-by-step explanation:

Answer:

your answers will be 12 and 7

Step-by-step explanation:

a few points to help that are related to numbers

Sum of two odd numbers will always be even.

Sum of two even numbers will always be even.

Sum of one odd and one even number will always be odd.

Let the both numbers be first and second.

According to the problem statement:

first + second = 19

first – second = 5

Add both equations:

first + second + first – second = 19 + 5

2 * first = 24

first = 24 / 2

first = 12

So from this we get first = 12, put this value in any equation i.e.

first + second = 19 (Put the value of first in this equation)

12+ second = 19

second = 19 – 12

second = 7

So, the numbers are 12 and 7.

Answer:

the correct answer must be 5x - 5 not 5x - 1

Step-by-step explanation:

when we have a question such as 5(x - 1)

we must multiply both the numbers by 5

so we get 5 X x and 5 X -1

so it will be 5x - 5 which is the answer.

The number of 5 hours is the cost to rent a snowboard the same for each company.

And the cost is $75.

Two algebraic expressions having the same value and symbol '=' in between are called an equation.

Given:

It costs $5 per hour to rent a snowboard from a certain ski rental company, plus a $50 deposit.

Let n be the number of hours.

So, 5n + 50.

Another ski rental company charges $10 per hour to rent a snowboard, plus a $25 deposit.

10n + 25

When the cost is equal,

5n + 50 = 10n + 25

5n = 25

n = 5

And the cost is $75.

Therefore, all the required values are given above.

Answer:

measure of angle ADC = 100°

measure of angle DCB = 39°

Step-by-step explanation:

We know that all the interior angles of a triangle add up to equal 180°, so we can set up an equation based on what we know from the figure (Angle C is the sum of [tex](4x-1)[/tex]° and [tex](2x+17)[/tex]°):

180° = 43° + 61° + [[tex](4x-1)[/tex]° + [tex](2x+17)[/tex]°]

180° = 43° + 61° + [tex]6x +16[/tex]°

180° = 104° + 16° + [tex]6x[/tex]

180° = 120° + [tex]6x[/tex]

60° = [tex]6x[/tex]

10° = [tex]x[/tex]

Now that we know the value of [tex]x[/tex], we can easily plug in 10° for [tex]x[/tex] in the angles we need to find.

The second angle we need to find uses [tex]x[/tex], so we can now find it. Angle DCB is, according to the figure, equal to [tex]4x-1[/tex].

[tex]4x-1[/tex]

[tex]4(10)-1\\40-1\\39[/tex]

Thus, the measure of angle DCB is equal to 39°.

However, angle ADC is defined in terms of [tex]y[/tex], so we'll have to find the value of [tex]y[/tex]. This is easy, however, because the two angles using [tex]y[/tex] meet together to form a straight line. Since we know that a straight line has an angle measure of 180°, we can once again set our equation equal to 180°.

180° = [tex](3y+7)+(3y-13)[/tex]

180° = [tex]6y[/tex] + 7° - 13°

180° = [tex]6y[/tex] - 6°

186° = [tex]6y[/tex]

31° = [tex]y[/tex]

Now, we'll simply substitute 31° for [tex]y[/tex] in the measure of angle ADC:

[tex]3y+7\\3(31)+7\\93+7\\100[/tex]

Therefore, the measure of angle ADC is equal to 100°.

The measure of <ADC is 100 Degree and measure of <DCB is 39 Degree.

The angle sum property of a triangle states that the sum of the angles of a triangle is equal to 180º.

Given:

First, (3y+ 7) + (3y - 13) = 180 (Linear Pair)

6y - 6 = 180

6y = 186

y = 31

So, measure of <ADC = 3y+ 7 = 3(31)+ 7 = 93 + 7 = 100 Degree

In Triangle ADC, using Angle Sum property

3y -13 + 61 + 4x - 1 = 180

93 - 13 + 61 - 1 + 4x = 180

4x = 40

x= 10

So, the measure of <DCB = 4x-1 = 4(10)-1 = 39 Degree.

Answer:

68%     32%

73.5%   26.5%

Step-by-step explanation:

Start:

total number = 561 + 264 = 825

glucose aversion = 561

percent = 561/825 × 100% = 68%

no glucose aversion: 264

percent = 264/825 × 100% = 32%

End:

total number = 441 + 159 = 600

glucose aversion = 441

percent = 441/600 × 100% = 73.5%

no glucose aversion: 159

percent = 159/600 × 100% = 26.5%
