Answer:
0.33 litres
Step-by-step explanation:
If a mug can hold a volume of m litres, then a bowl can hold a volume of m+0.07 litres. The total volume held by the given containers is ...
3(m +0.07) +4m = 2.52
7m +0.21 = 2.52 . . . . . . . . simplify
7m = 2.31 . . . . . . . . . . . . . subtract 0.21
m = 0.33 . . . . . . . . . . . . . divide by 7
Each mug can hold 0.33 litres.
Answer:
25 and -31
Step-by-step explanation:
Notice that if all the negatives were positive, you would have the arithmetic sequence 1, 7, 13, 19, on and on, adding 6 every time. So basically we have a geometric and arithmetic sequence combined, with the geometric sequence making it positive, and negative, and the arithmetic sequence adding 6 every time. This means the answer(s) are 25 and -31.
Answer:
John is 31
Ella is 25
Step-by-step explanation:
Let sister's age be x, then John's age is (x + 6). So from sentence 2,
(3x) - 2(x + 6) = 13
3x - 2x - 12 = 13
x = 13 + 12 = 25
and x + 6 = 31
