Answer:
1 st pattern 48+122 = 170
2 nd pattern 8½+3½ = 5
so, 3rd pattern 41+13= 54 (B)
Answer:
If we forget about the £150 more for a second then we can think of some very basic scenarios where the 5 : 2 ratio is satisfied. For example, Jon has £5 Nik has £2 or Jon has £10 Nik has £4 and so on. From this information we can set up an equation to find what Nik has if Jon has say £100. What is that equation? we let J represent how much Jon has and N represent how much Nik has then we can say2J = 5N and this comes directly from the ratio given.Now we consider the £150 more that Jon gets and we can set up another equationJ = N + 150 if Nik got £150 more then they'd have the same.So now we have 2 equations and two variables and we can solve it like they're simultaneous equations. There are a couple of methods for solving simultaneous equations but in this case the method to use is obvious, substitution. We use substitution because our second equation J = N + 150 is already in terms of J so we can just substitute it in to the first equation. By doing this we get2(N + 150) = 5N now we expand the brackets2N + 300 = 5N take N on to one side300 = 3N make N the subjectN = 100 we have an equation to find what J is if N is 100, 2J = 5N2J = 5(100) make J the subjectJ = 250
Step-by-step explanation:
(3.5,3.5) because then you would just find the midpoint in between the two point.
Answer:
The decimal disappears
Step-by-step explanation:
0.46 * 50
You can multiply 46 by 50 to get 2300
Then you divide by 100 by moving the decimal point to the left two places because to get from 0.46 to 46, you multiplied by 100, so you use inverse operation.
