45 ÷ 3 = 15
21 ÷ 3 = 7
12 ÷ 3 = 4
(4 + 15) x 7 = 133
OR if you’re using bedmas/pedmas
4 + (15 x 7) = 109
F (-3) = -3(-3) -4
F(-3) = 9 - 4
F(-3) = 5
(5,-3) is the ordered pair
First find 10%
(1200 divided by 10)
10% = £120
Then add it onto the original amount
£1200 + £120 = £1320
I'm not sure you finished the question because there isn't an x there but I simplified it in case that's what you wanted
2 + 6 = 8
4 - 3 = 1
8(1) = 8
8 = 8
Answer:
The estimate is going to be about 9.9
