Answer:
Hi there!
Your answer is: 150 people prefer that school assemblies be held on Friday afternoon
Step-by-step explanation:
3 out of 4 students means that 75% of students prefer assemblies on Friday afternoon!
To find 75% of 200:
200 = 100%
/100 to find 1%
2 people = 1%
Multiply it by 75 to determine 75%
2×75= 150
150people is 75% of 200 people!
I hope this makes sense! Let me know if you have questions!
Answer:
How many items did Bob produce last week? 32 items.
Step-by-step explanation:
(1) Last week Bob was paid total of $480 for the items that he produced that week.
(2) This week Bob produced 2 items more than last week and was paid a total of $510 for the items that he produced this week.
a) Let's start with the simplest case: he produced 36 or less items this week.
In this case he produced less than 36 items last week too.
So he was paid the same amount of dollar per item.
Using (1) and (2) assumptions we have:
$480+2X=$510
⇒2X=$510-$480
⇒2X=$30
⇒2X=$30/2
⇒X=$15
He was paid $15 per item.
Last week he was paid $480.
480/15= 32 items.
This week he was paid $510.
510/15=34 items.
The other cases has no solutions.
5x -3 = 12
5x -3 + 3 = 12 + 3 [Add 3 to each side]
5x + 0 = 15 [Evaluate]
5x/5 = 15/5 [Divide each side by 5]
1x = 3 [Evaluate]
The answer I get is the number 3.
