There can only be one reason for that . . . making
something tough out of something easy.

<u>-19  =  x - 7</u>

How could you get 'x' all by itself on one side,
and everything else on the other side ?

What if you add  7  to each side ?

Then you have    <em> -12  =  x </em>   .  To your amazement, that's the solution !

The area of a rectangular hotel room is 260 square feet. The perimeter is 66 feet. What are the dimensions of the room?
docker41 [41]

Length + width = half the perimeter

66/2 = 33 feet

Length  +  width = 33 feet

List the factors of 260: 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130 and 260.

Find the two factors that when added together equal 33:

13 + 20 = 33

The dimensions are 13 feet by 20 feet

What is the diameter of this circle if the circumference is 30 x inches?
ch4aika [34]

Answer:

<h2>10 inches</h2>

Step-by-step explanation:

Given the circumference= 30 in

we know that the formula for circumference is

C= 2\pi r

30= 2*3.142*r\\\\r= \frac{30}{2*3.142} \\\r= \frac{30}{6.248}\\\r= 4.77 in

The diameter is 2*r= 4.77*2=9.55 in

Approximately the diameter is 10 inches

Please help me if you can. Please also write how you got the answer thank you.

Answer:

Question 9: Variables: (smallest) s, q, r (largest)

Question 10: 5 whole numbers (7, 8, 9, 10, and 11)

Step-by-step explanation:

For question nine, there are two given statements... s=q-2 and q<r. Say we plug in 10000 (a really big #) in for q, then we would get s=9998 and r>10000. This way, we can see that s would be the smallest, then q, and r is the largest. <em>(q<r can be written as r>q)</em>

<em />

For question 10, it states \frac{1}{4}. This can be split into \frac{3}{x} and \frac{3}{x} . When x is 12 in the first equation then \frac{3}{12} = \frac{1}{4} and when x is 6 in the second equation \frac{3}{6} =0.5 (0.5 is also  \frac{1}{2}). Therefore, x must be a whole number less than 12 and greater than 6, and it cannot be either 12 or 6. Whole numbers between 6 and 12 are 7, 8, 9, 10, and 11  or  5 whole numbers.

Pachacha [2.7K]

Answer:

140

Step-by-step explanation:

Since 25% is 1/4 of 100, that means that 35 is 1/4 of the total amount of members in the club. So, 35 times 4 is 140.
