8th grader here, what do you need help with?
I just need the answers to these two questions.Thanks
Answer:
4. a. y = 2x
b. she will need 12 packs of cashews to 24 cans of peanuts to make the mix.
5. a. YES
b. y = 2.5x
c. $30
d. 24 pounds
e. See attachment
Step-by-step explanation:
4.a. packages of cashews = x
Cans of peanuts = y
The equation that represents the relationship between x and y can be expressed in slope-intercept form as y = mx
Slope = m,
Finding slope (m) using two pairs (1, 2) and (2, 4):
Slope = ∆y/∆x = (4 - 2)/(2 - 1) = ²/1 = 2
m = 2.
To write the equation, substitute m = 2 into y = mx
The equation would be:
y = 2x
b. The ordered pair (12, 24) in the context of the problem means she will need 12 packs of cashews to 24 cans of peanuts to make the mix.
5. a. The cost of candy is proportional to the amount of candy because: 5/2 = 7.5/3 = 12.5/5 = 2.5 = constant of proportionality/unit rate
b. An equation can be written to show the proportional relationship in the form of y = mx.
Where, m = constant of proportionality/unit rate
x = amount of candy
y = cost on dollars
Thus, substitute m = 2.5 into y = mx
The equation would be:
y = 2.5x
c. To find how much it would cost (y) for 12 pounds of candy (x), substitute x = 12 into y = 2.5x to find y.
Thus:
y = 2.5(12) = 30
It would cost $30 for 12 pounds of candy
d. To find the maximum amount of candy (x) you can buy with $60 (y), substitute y = 60 into y = 2.5x
Thus:
60 = 2.5x
Divide both sides by 2.5
60/2.5 = 2.5x/2.5
24 = x
x = 24
Maximum amount of candy you can buy with $60 is 24 pounds of candy.

Explain how to add +20 and -36. GIVING BRAINLIEST TO WHOEVER GIVE THE RIGHT ANSWER!!! :)
Answer:
-16
Step-by-step explanation:
In this problem, we are adding a negative integer and a positive integer. From this, we already know that the sum will be negative. (- plus + = -)
Since 20 is positive, you can remove the plus sign so your equation looks like
20 - 36
Next, subtract to get -16

which of the following explains how triangle BEI could be proven similar to triangle CEH using the AA similarity postulate?
Answer:
∠BEI ≅ ∠CEH because vertical angles are congruent; rotate ΔCEH 180° around point E, then translate point C to point B to confirm∠IBE ≅ HCE.

In a class of 100 half the students are science majors and half are liberal art majors. A student who is a science major has a 0:9 probability of passing a given test whilst a student who is liberal art major has only a probability of 0:7. We pick 2 students at random without replacement and give them the test. What is the probability that both students pass the exam
Answer:
P(both students passed the exam) = 0.61948
Step-by-step explanation:
From the given information:
P(both students passed the exam) = P(both are science students or both are art major students or one is from each group)
= P (both are science students) + P(both are art students) + P(one from each group)
where;
P (both are science students) = (50/100) (0.9) × (44/99) × (0.9) = 0.18
P(both students are art) = (50/100) (0.7) × (49/99) 0.7 = 0.1213
P(one of the student are from each group) = (50/100) (0.9) ×(50/99) (0.7) + (50/100) (0.7)× (50/99)(0.9) =0.3182
P(both students passed the exam) = 0.18 + 0.1213 + 0.3182
P(both students passed the exam) = 0.61948
Arturo can walk 4 miles in 1 hour. How many miles can he walk 3 hours?
Answer:
12
Step-by-step explanation:
Mrs. Carroll purchases new materials for her math classroom. New workbooks cost $7.00 each, and new dry erase boards cost $5.00 each. She had a budget of $50.00. Write an inequality to represent the situation. Let w represent the number of workbooks and let d represent the number of dry erase boards.
Answer:
[tex]7w+5d\leq 50[/tex]
Step-by-step explanation
Let w represent the number of workbooks
Let d represent the number of dry erase boards
Then , we can create the inequality for this situation
[tex]7w+5d\leq 50[/tex]

The expression 12 dollars times t can be used to find the total cost for t tickets to the movie theater. What is the total cost of 5 tickets?
Answer:
$60
Step-by-step explanation:
$12t = total costt = 5$12*5 = $60Answer:
$60
Step-by-step explanation:
This is the answer because:
1) $12t = total cost
2) t = tickets, 5 = tickets
3) $12 x 5 = $60
Therefore, the answer is $60.
Hope this helps! :D
