Answer:
B. Beth's age is 18 years, and Sally's age is 42 years.
Step-by-step explanation:
You can solve this question in a couple of different ways. First, you can use process of elimination. You know that Sally is older than Beth because she has to be 3 times older 6 years ago, so you can get rid of options C and D because they both show Beth as being older. Now you only have A and B, and you can use a different process. Now from just looking at it, you can tell that A actually already shows Sally as 3 times Beth's age, 15 * 3 = 45. If you go to B, you can go ahead and subtract 6 from 18 (Beth's age) which will give you 12, and then multiply that by 3 to get 36. Now if you take 42 (Sally's age) and subtract 6 from it as well, you will get 36. This means that is lines up. To simplify, you are subtracting 6 from both 18 and 42, and then you are multiplying the lower number by 3 to see if it gets to the bigger number.
Hope this helped ^-^
Answer:
2pi?
Step-by-step explanation:
Pi is an irrational number so I guess double of pi would be irrational too.
2pi would be something like 6.28318531...
The total price for the gallons of paint will be 35.75p
The total price for the rollers will be 6r
So the equation if the customer have 190 will be
price for gallons of paint + price for rollers = 190
35.75p + 6r = 190

Answer:
<em><u>96</u></em>
<em><u>Step-by-step explanation:</u></em>
<em><u>So for number 5 your going to multiply 8 and 12</u></em>
<em><u /></em>
<em><u>8 x 12 = 96</u></em>
<em><u>So the answer for 5 is </u></em>
<em><u>Answer: 96</u></em>
![\left( \dfrac 1 {64} \right)^{- 5/6} =64^{5/6} = (\sqrt[6]{64})^5 = 2^5 =32](https://tex.z-dn.net/?f=%20%5Cleft%28%20%5Cdfrac%201%20%7B64%7D%20%5Cright%29%5E%7B-%205%2F6%7D%20%3D64%5E%7B5%2F6%7D%20%3D%20%28%5Csqrt%5B6%5D%7B64%7D%29%5E5%20%3D%202%5E5%20%3D32)
TRUE
![\sqrt[5]{36^4}=36^{4/5}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B36%5E4%7D%3D36%5E%7B4%2F5%7D)
which surely isn't 36. FALSE
FALSE
For the fourth one we have a
which isnt
so this is FALSE.
No fractions in that one so FALSE.
