Answer:
The first one can be anything as long as it has y=-7x
Second, the solution for the equations is (3 3/4, 0), I found that by using the elimination method. I don’t remember how to do the rest, I’m sorry
Answer:
44
Step-by-step explanation:
1) we know that opposite sides of a parallelogram are congruent so
4x+28=10x+4
2) subtract 4 on both sides
4x+24=10x
3)subtract 4x on both sides
24=6x
4)divide by 6 on both sides
4=x
5)substitute for x
length of RS =10(4)+4
length of RD=44
It is possible to make 5 equal rows of 4. That covers 20 animals, leaving 2 animals behind. Therefore, there will be 2 animals not in equal rows.
Answer:
312 people
Step-by-step explanation:
Hello!
<u>Step 1:</u>
First, we want to calculate what percentage of the random sample voted pretzels. To do that, we divide the number of pretzel voters depending on the total number of voters.
Calculate:
- Pretzel voters ÷ Total voters
- 27 ÷ (78 + 27 + 55 + 65)
- 27 ÷ 225
- 0.12
- 12%
<u />
<u>So, approximately 12% of the sample voted on pretzels.</u>
<u>Step 2:</u>
Now that we know the average percentage of people that want pretzels, we can find the same percentage of the actual population of 2600 people.
We need to solve for 12% of 2600
Calculate:
- 12% of 2600
- 0.12 * 2600
- 312
<u>Based on our percentages, we predict that 312 people favor pretzels.</u>
