Which expressions are equivalent to the expression 3x2−5a3+2y4?
Select all that apply.
2y4−5a3+3x2, 2y4+3x2−5a3, 3x2−2y4+5a3, or 3x2+2y4−5a3
Answers
Answer:
The first two answers and the last one are correct.
Step-by-step explanation:
In order to check if the expressions are equivalent, look at the number in front (coefficient) and its sign (positive/plus or negative/minus), the letter (variable) and its exponent.
In the question the 3x² is a (positive or plus) +3x²
The 5a³ is a (negative or minus) -5a³
The 2y^4 is also (positive or plus).
All of the signs in the answers are the same as the question (as well as the number, letter, exponent) EXCEPT for the third answer has a different sign. It has NEGATIVE 2y^4 and POSITIVE 5a³ which are wrong.
The terms can be rearranged, but they MUST keep their positive or negative signs with them, and keep them the same sign as the original question.

Answers
Answer:
equal to 74
Step-by-step explanation:
To evaluate the expression, we will follow the order of operations (PEMDAS):
Start with the exponent: 2^4 = 16Next, evaluate the division: 14 - 6 = 8Then, divide 16 by 8: 16 ÷ 8 = 2Next, multiply the result by 2: 2 x 2 = 4Finally, subtract 4 from 78: 78 - 4 = 74So the expression 78 - 2^4 ÷ (14 - 6) x 2 is equal to 74.
Let’s solve separately first
2^4 = 2’s power 4 = 2*2*2*2 = 16
14-6 = 8
2” = 2*2 = 4
78 - 16 / 8 * 4
= 78 - 2 * 4
= 78 - 8 = 70

The correct option regarding whether the table shows a proportional relationship is given as follows:
Yes.
What is a proportional relationship?A proportional relationship is defined as follows:
y = kx.
In which k is the constant of proportionality.
The constant for a pair (x,y) is given as follows:
k = y/x.
When x = 5/6, y = 2, hence the constant is given as follows:
k = 2/(5/6)
k = 12/5
k = 2.4.
When x = 25/6, y = 10, hence the constant is given as follows:
k = 10/(25/6)
k = 60/25
k = 2.4.
When x = 125/6, y = 50, hence the constant is given as follows:
k = 50/(125/6)
k = 300/125
k = 2.4.
Same constant, hence the table in fact represents a proportional relationship.

Does 6/10+8/100 = 14/10 or 68/10??
Answers
Answer:
The answer is 68/100 or 17/25
Step-by-step explanation:
To solve this problem, you need to find common denominators. In this equation, the easiest way to do this is to make both fractions have a denominator of 100. 8/100 is already in the proper denominator, and 6/10 can be multiplied by 10 to get 60/100. After adding, you get 68/100 which simplifies to 17/25

Together, teammates Pedro and Ricky got 2685 base hits last season. Pedro had 281 more hits than Ricky. How many hits did each player have?
Answers
Answer:
1,483 is the answer
Answer:
Step-by-step explanation:
Let's say Pedro got x hits
and Ricky got y hits.Given,Pedro and Ricky together got 2685 hits.So, the
equation will be as (x+y)=2685................eq (1)
Given,Pedro had 281 more hits than Ricky.So the equation looks like
x=281+y..........eq(2).
substitute eq(2) in eq(1).We get,
2685=(281+y)+y
2685=281+2y
2685-281=2y
2404=2y
2404/2=y
y=1202
substitute y=1202 in eq(2).We get,
x=1202+281
x=1483
So,Pedro hit 1483 and Ricky hit 1202

A polygon is shown:
A polygon MNOPQR is shown. The top vertex on the left is labeled M, and rest of the vertices are labeled clockwise starting from the top left vertex labeled, M. The side MN is parallel to side QR. The side MR is parallel to side PQ. The side MN is labeled as 5 units. The side QR is labeled as 7 units. The side MR is labeled as 3 units, and the side NO is labeled as 2 units.
The area of polygon MNOPQR = Area of a rectangle that is 15 square units + Area of a rectangle that is
square units. (Input whole numbers only, such as 8.) (5 points)
Answers
Answer:
The area of polygon MNOPQR = Area of a rectangle that is 15 square units + Area of a rectangle that is 2 square units.
Step-by-step explanation:
In the given polygon MNOPQR, side MN is parallel to side RQ and the side MR is parallel to side PQ
We will draw a perpendicular line from point O on the side RQ, which will intersect RQ at point S. So, we can now divide the whole polygon into two different rectangles MNSR and OPQS with the areas as A₁ and A₂ respectively.
In rectangle MNSR, length(MN) = 5 units and width (MR) = 3 units
According to the formula for Area of rectangle,
A₁ = (length)×(width)
A₁ = (5 units)×(3 units)
A₁ = 15 square units
Now in rectangle MNSR, side MN= side RS and side MR = side NS,
so RS= 5 units and NS= 3 units
That means, SQ= RQ- RS = 7-5 = 2 units
and OS= NS - NO = 3- 2 = 1 unit
In rectangle OPQS, we have length(SQ) = 2 units and width(OS) = 1 unit
So, A₂ = (length)×(width)
A₂ = (2 units)×(1 unit)
A₂ = 2 square units
So, the area of polygon MNOPQR = (Area of a rectangle that is 15 square units + Area of a rectangle that is 2 square units)

Devon is making greeting cards, which she will sell by the box at an arts fair. She paid $20 for a booth at the fair, and the materials for each box of cards cost $6. She will sell the cards for $10 per box of cards. At some point, she will sell enough cards so that her sales cover her expenditures. How much will the sales and expenditures be? How many cards will that take?
Answers
Next, let's find out how many boxes of cards she needs to sell in order to earn enough money to cover her expenditures. She'll sell each box of cards for $10, so she'll need to sell $26 / $10 = 2.6 boxes of cards (rounded up to 3 boxes).
So, her sales will be 3 boxes * $10 per box = $30. And her expenditures and sales will both be $30

Answer: hope this helps ♡
Jack will be twice as old as his sister in -8 years.
Step-by-step explanation:
If Jack could age backwards, he would be twice as old as his sister in -8 years.
Jack = 12
Amy = 2
2*2 (Amy) = 4
12 - 8 = 4 (we got 8 by subtracting amy's age from jack's age: 12-2=8)
4 is double 2.
