You collect a total of $75 in donations from three people. The three donations are in the ratio 4 : 4 : 7.

Answer:

Step-by-step explanation:

2 tables and 3 chairs is $705

Let t stand for table and c stand for chair

3c + 2t = 705

We are told that the table costs $40 more than the chair, so t = c + 40

Now we can insert this into the equation

3c + 2(c + 40) = 705

The next step is to distribute the 2

3c + 2c + 80 = 705

Then combine like terms

5c + 80 = 705

To get the variable by itself, you have to subtract the 80 from both sides.

5c = 705 - 80

5c = 625

This means that 5 chairs costs $625.

Divided both sides by 5 to isolate the variable

c = 625/5

c = 125

Great, now you know the cost of one chair, $125!

The question is asking how much a table costs, and we know that a table costs $40 more than a chair.

A table costs $125 + $40

A table costs $165

Hope this helps! =)

The constant speed for the given distance and time is 123/2 miles/hour.

Given that, Andrea drove [tex]20\frac{1}{2}[/tex] miles in 1/3 of an hour at constant speed.

The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.

Here, [tex]20\frac{1}{2} = \frac{41}{2}[/tex]

Now, speed = Distance ÷ Time

= 41/2 ÷ 1/3

Change division to multiplication and reciprocal the fraction

That is, 41/2 × 3/1

= 123/2 miles/hour

Therefore, the constant speed for the given distance and time is 123/2 miles/hour.

I try my best

2(2/5) divided 2(-1/5)

we do PEMDAS meaning parenthesis first

2(2/5) = 4/5(calculator)

or

2/1x2/5=4/5

now

2/1x-1/5=-2/5

now we do division

4/5/-2/5 we get -2

Let the bigger number be 'U' and the smaller number 't'.

Since the two numbers have a sum of 32, then   U + t = 32.

& since one number is 6 more than the other, the U - 6 = t

⇒ U + U - 6 = 32

             2U = 38

                U = 19

By substituting fot the value of U we found,

19 - 6 = t

      t  = 13

Answer:

13 and 19

Step-by-step explanation:

let's first set the two mystery numbers as "x"

and we know that x + (x + 6) = 32 since one of the numbers is 6 more than the other.

now let's set it up:

x + x + 6 = 32

= 2x = 26

= x = 13

so we know that x = 13 now we need to find the other number so we do:

13 + 6 = 19

now to check our work:

13 + 19 = 32

Answer:

As shown in the attachment,

Step-by-step explanation:

The parameters of a linear function are the slope, and the intercepts.

A linear function is represented as:

[tex]\mathbf{y = mx + b}[/tex]

Where:

m represents the slope or the rates

b represents the y intercept or the initial value of the function.

So, by comparison:

[tex]\mathbf{m = 3.5}[/tex]

[tex]\mathbf{b = 4}[/tex]

So, we have:

The price per game is 3.5 (i.e. the slope), and the shoe rental charge is 3.5 (i.e. the y-intercept)

The temperature in Fahrenheit after preheating for 2 minutes is 103⁰F

The question looks incomplete but we can as well find the temperature in Fahrenheit after preheating for 2 minutes

Give the function t = 19m + 65 that represents the temperature t (in degrees Fahrenheit) of an oven after preheating for m minutes.

If t = 2,

t = 19(2) + 65

t = 38 + 65

t = 103⁰F

Hence the temperature in Fahrenheit after preheating for 2 minutes is 103⁰F

Answer:

1. T

2. T

3. T

4. F

Step-by-step explanation:

1. The tempature must be 0 degrees celcus or 32 degrees fahrenheit or below to snow.

2. An acute angle is less than 90 degrees

3. Supplementary angles are 2 angles that add up to 180.

4. Complementary angles are any 2 angles that add up to 90 degrees BUT they do not have to be only 45 degrees and can be any 2 degrees that add up to 90.

This shows that there are 141 men and 21 women in the meeting

Let the number of men present be x

Let the number of women present be y

If the total number of students present in the meeting is 162, hence;

x + y = 162 ............ 1

If  there were 15 men more than 6 times the women, then;

x = 6y + 15 ...................2

Substitute equation 2 into 1:

6y + 15 + y = 162

7y + 15 = 162

7y = 162 - 15

7y = 147

y = 21

Recall that x = 6y + 15

x = 6(21) + 15

x = 126 + 15

x = 141

This shows that there are 141 men and 21 women in the meeting
