Answer:
3 - x ≥ 9
Step-by-step explanation:
At least in inequality means greater than or equal to (≥)
Difference in mathematics means subtraction
The difference between a number x and 3
3 - x
is at least nine
3 - x ≥ 9
The inequality for the sentence is
3 - x ≥ 9
1-5q+ 2(2.5q+8)
1-5q+5q+16
0+15
15
(The q goes away because in addition a negative and a positive of the same # equal 0 since its 0 there is no letter)
If Cg stands for centigrams,500 Cg = 5 grams
5.2>5
5.2 grams is heavier
I think by 1-5 you mean 1/5??
1/5 = 0.20 = 20%
50% + 20% = 70%
100-70 = 30
so 30% were sponge cakes
