how do I simplify this algebraic expression 3x+2a-4x
Start by changing the -4x to + -4x.
So we have 3x + 2a + -4x.
To simplify, we can only combine what are called our like terms and in this problem, we have a pair of like terms in our x terms.
3x + -4x simplifies to -x.
So our answer is -x + 2a.
Note that if you wrote your answer as -1x + 2a, it means the same thing. However, as we move farther into math, we usually tend to drop the -1 or 1 that is in front of a variable since it's implied

Students in another survey were asked whether they plan to attend summer camp. Out of the 56 students in the survey, 44% said yes. Use rounding and compatible numbers to estimate how many students plan to attend summer camp.
Answer:
Students to attend camp = 56 x 44/100 = 24.64
Students to attend camp = 25
Step-by-step explanation:
Answer:
≈25 students
Step-by-step explanation:
Find out 44% of 56:
(44*56)÷100=
2464÷100=

So about 25 students out of 56 said yes, they were going to attend summer camp.
A bag contains marbles of four different colors listed below. What is the probability of picking a BLUE marble at random out of the bag?
8 blue marbles, 24 red marbles, 16 green marbles, 4 yellow marbles.
~
1) 8/100
2) 2/13
3) 6/13
4) 4/13
Step-by-step explanation:
Total marbles = 24 + 8 + 16 + 4 = 52
Probability of blue marble = 8/ 52 = 4 / 26 = 2 / 13
Option 2 is the correct answer
James has g amount of games. Samuel, his friend, has 4 times as many games as James. Write an algebraic expression to represent how many games James has and how many games Samuel has in terms of g.
Answer: The answer is given below
Step-by-step explanation:
From the question, we are told that James has a lot of games and his friend Samuel, has 4 times as many games as James.
So let the number of games that James has be denoted by g.
Since Samuel has 4 times as the number of games that James has, then Samuel's game will be
= 4 × g
= 4g
Therefore, the expression for James will be g and the expression for the number of games Samuel has is 4g.
Jackson and Xavier are both solving the multiplication 0.8 x 5. Jackson gets 4 as a solution, and Xavier gets 0.4. Xavier said to Jackson, "Your answer of 4 can't be right for 0.8 x 5. You need a decimal point because a product always has the same number
Answer:
Jackson
0.8×5=4
Xavier
0.8×5=0.4
If Xavier said to Jackson that his answer of 4 can't be right.
Jackson needs a decimal point because a product always have the same answer.
Then,
Xavier is right with his sayings but wrong with the answer of 0.4
The correct answer is 4.0
The decimal point should be counted from the back not from the front as Xavier did

Khloe invested $11,000 in an account paying an interest rate of 4.8% compounded continuously. Assuming no deposits or withdrawals are made, how much money, to the nearest ten dollars, would be in the account after 17 years?
Answer:
Step-by-step explanation:
The compound amount formula for continuous compounding is
A = Pe^(rt), where P is the initial amount, r is the interest rate as a decimal fraction, and t is the time in years. Here we have:
A = $11,000e^(0.048*17) = $24,875.80
Rounding this off to the nearest ten dollars, we get $24,880.
The amount of money that should be in the account after 17 years is $24,875.80.
Calculation of the amount of money:Since Khloe invested $11,000 in an account paying an interest rate of 4.8% compounded continuously. And, there is 17 years
So, the amount should be
A = $11,000e^(0.048*17)
= $24,875.80
= $24,880
hence, The amount of money that should be in the account after 17 years is $24,875.80.

Answer:
59.62075 (if you use 3.14 for pi) 59.65099051 ( if you just use regular pi)
Step-by-step explanation:
i personally use 3.14 for pi. its just easi×er.
so the surface area formula for a cone is
π [tex]rl[/tex] + π[tex]r^{2}[/tex]
since the formula is looking for radius and not diameter, we change 3.5 to 1.75 (3.5 ÷ 2)
so it would be
(3.14×1.75×9.1) + (3.14×[tex]1.75^{2}[/tex])
which that equals
59.62075

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
The number of copies the copy machine makes = 231 copies
Time required by the to make 231 copies = 5 minutes 15 seconds
5 minutes = 5 x 60 seconds
5 minutes = 300 seconds
5 minutes 15 seconds = 300 + 15 seconds
5 minutes 15 seconds = 315 seconds
So , Time required by the to make 231 copies = 315 seconds
Now , number of copies in 1 minute = 60 x ( The number of copies the copy machine makes / Time required by the to make 231 copies )
Substituting the values in the equation , we get
Number of copies in one minute A = 60 x ( 231 / 315 )
Number of copies in one minute A = 60 x 0.733
Number of copies in one minute A = 44 copies
Therefore , the value of A is 44 copies
Hence , the number of copies is 44 copies

Aless and Louis are going to put a rectangular pool in their backyard. The cost of installation is $6,000. If the dimensions of the pool are 30 meters by 20 meters by 2 meters, what is the cost of the installation of their pool per cubic meter?
Answer:
cost of the pool per cubic meters = $5
Step-by-step explanation:
The rectangular pool has a dimension of 30 m by 20 m by 2 m. To know the cost of the pool per cubic meter we have to calculate the volume of the pool . Then divide the total cost of the pool by it volume.
volume of the rectangular pool = length × height × width
volume of the rectangular pool = 30 × 20 × 2
volume of the rectangular pool = 1200 m²
The cost of installation is $6000 . The volume of the pool is 1200 cubic meters.
cost per cubic meters = total cost of installation/volume
cost per cubic meters = 6000/1200
cost of the pool per cubic meters = $5
