The nearest integer would be 8.
Answer:
1) 30% 2) 124 yellow buttons
Step-by-step explanation:
1) 12 B’s out of 40 12/40= .3 x 100 = 30
2) 20%, 20/100, .2
620 x .2 = 124
15)
4(a+b) + 12
= 4a + 4b + 12
= 4(a +b + 3)
answer is
b) 4(a +b + 3)
16)
x - 4(2x + 2)
= x - 8x - 8
= -7x - 8
answer
-7x - 8
The three is in the ten thousands place; so it would equal thirty thousand. I'm not sure if that's how you wanted the answer though.
