Answer:

RS = 17

Step-by-step explanation:

(23-2x) + (9x-5) = 39

23-2x+9x-5 = 39

7x + 18 = 39

7x = 21

x = 3

Given: RS = 23-2x

23 - 2(3)

23 - 6 = 17

I need to know the answer to this
Brums [2.3K]

Answer: 276

Step-by-step explanation:

multiply 1/3 by 4/4 to make it similar to 5/12 that way you can add them. because the denominator is different from each other you can’t add them. once you do that you get 4/12, you then add 5/12 and that equals 9/12. in order to get to 12/12 you need 3/12 more. this 3/12 represents the 69 guest that chose vegetarian. the 5/12 represents the the guest who chose chicken and the 4/12 represents the ones who chose beef. now that you know 69 people is the same as 3/12 of all the guest. you then realize that 9 is divisible by 3. so you multiply 69 by 3 because 3 goes into 9 3 times. which gives you 207. 207 represents 9/12. and we already know 69 represents 3/12. so you add them together and get 276. sorry if that was confusing but that’s the best way i can explain it.

There are 534 car parking spaces but 478 spaces are occupied,round to the nearest 10
suter [353]

Answer:

60

Step-by-step explanation:

If 478 out of 534 parking spaces are taken, then you will be <u>subtracting</u>. When you subtract 534 and 478 (534-478), then you get 54. Remember 5 and up round to 10. 4 and below round to 0. So 56 rounds to 60 because 6 is greater than 5.

Hope it helps!

Please help me now plz <br> I will mark you brainliest
Stella [2.4K]

Answer:

x=13

Step-by-step explanation:

The right side is a right triangle

The base is 1/2 of the bottom or 5

The height is 12 and the hypotenuse is x

We can use the Pythagorean theorem

a^2 +b^2 = c^2

5^2 +12^2=x^2

25+144 = x^2

169=x^2

Take the square root of each side

sqrt(169) = sqrt(x^2)

13=x
