Answer:
The 2 represents that each toppings costs $2.
M-(M•0.16) and M(.84) because the first one you need to multiply to find what 16% of m is then subtract that by m for the second one you subtract .16 from 1 which is .84, then you multiply that by m which will automatically take the 16% decrease which will give you your answer. Both ways give you a 16% decrease of m. I hope this helped
Step-by-step explanation:
A. 4(a + 1) = 2
= 4a + 4 = 2
= 4a = 2-4 = - 2
= a = - 2/ 4 = - 1/2
B. 3 - 9x = - 6-8x
3 + 6 = - 8x +9x
9 = x
C. 12x - 3 = 14x - 35
- 3 + 35 = 14x - 12x
32 = 2x
32 / 2 = x
16 = x
Answer:
£5 : £25
Step-by-step explanation:
Sum the parts of the ratio, 1 + 5 = 6 parts
Divide the quantity by 6 to find the value of one part of the ratio
£30 ÷ 6 = £5 ← value of 1 part of the ratio, thus
5 parts = 5 × £5 = £25
Thus 1 : 5 = £5 : £25
