Your answer would be -1.3
They both have a y and x axis and they both represent things
The answer is E because there is 54 crayons and you put 9 crayons in each box so 54 divide 9 = 6
For these, n is equal to the term you want. So you substitute the number in for whichever term you want. This means:
a) 1 (1st term) + 5 = 6
2 (2nd term) + 5 = 7
3 (3rd term) + 5 = 8
4 (4th term) + 5 = 9
10 (10th term) + 5 = 15
And so on for b (not going to keep writing the term, I’m sure you get that by now.
b) 2(1) - 1 = (2x1) - 1 = 1
2(2) - 1 = (2x2) - 1 = 3
2(3) - 1 = (2x3) - 1 = 5
2(4) - 1 = (2x4) - 1 = 7
2(10) - 1 = (2x10) - 1 = 19
Hope this helps :)
First, you calculate the total amount of parts : 7 + 3 = 10
Next, divide the number by the total amount of parts : £500 ÷ 10 = £50
After that, you multiply the answer by the amount of parts needed on both sides of the ratio : £50 × 3 = £150 and £50 × 7 = £350
Finally put these answers back into the ratio : £150:£350
To check, make sure both sides of the ratio add up to the original number : £150 + £350 = £500
