Answer:
6
Step-by-step explanation:
On the fourth day, there were b^3 beads and 216 beads on the belt, which means b^3 = 216. Taking the cube root of both sides, we have b = 6, which means there were 6 beads on the belt on the first day.
Answer:
She need to make 98 on the last assignment.
Step-by-step explanation:
Average = 92
x = mark on last assignment
(88 + 97 + 91 + 86 + x) / 5 = 92
To solve for x...multiply 5 on each side
<em>(88 + 97 + 91 + 86 + x) / 5 * 5 = 92*5</em>
<em>This would get of / 5 so you don't need to divide by 5</em>
362 + x = 460
Subtract 362 from each side
x = 98
Answer:
and 
Step-by-step explanation:
The area of a rectangle is 
which factors through GCF, by finding the greatest common monomial factor between the two.
The length and width of the rectangle are and .
1. x - (-16) = -13
x= -3
2. n = -425------- n=-85 5
3. x + 6 < 15 x <9
4. x + (5-2) > 7 x >5
5. m < --- _ 48 m< 5 12
6. 5m > 45 m>8
7. 3x +4 < 37 x<10
