Step-by-step explanation:
Expression given,
[tex] \\ \longrightarrow \qquad \sf 5x+3x+2y+4y \\ \\ [/tex]
Here, in the expression we have to find the like terms.
So from the expression we that, 5x and 3x are like terms and 2y and 4y are like terms too, so now we have to combine them and then we will get a new expression so.
[tex]\\ \longrightarrow \qquad \sf 8x + 6y \\ \\ [/tex]
So, 8x + 6y is the new expression.

What is the volume of this triangular pyramid?
9 cm
7 cm
8 cm
Answer:
84 cm³
Step-by-step explanation:
The volume of a pyramid is given by the formula ...
V = 1/3Bh
where B is the area of the base.
__
The base is shown as a right triangle with legs 8 cm and 7 cm. Its area is given by the triangle formula ...
A = 1/2bh
A = 1/2(8 cm)(7 cm) = 28 cm²
Then the volume of the triangular pyramid is ...
V = 1/3(28 cm²)(9 cm) = 84 cm³
Answer: 84

Answer:
x = 3
s = 11
z = 14
y = 2
Let me know if you need an explanation for this, I would be happy to help :)
Answer:
1. x = 3
2. s = 11
3. z = 14
4. y = 2
Step-by-step explanation:
1. x + 9 = 12
12 - 9 = x
⇒ x = 3
2. s - 1 = 10
10 + 1 = s
⇒ s = 11
3. 3 = z - 11
z - 11 = 3
11 + 3 = z
⇒ z = 14
4. 5 + y = 7
7 - 5 = y
⇒ y = 2

Answer:
a = 8 2/3.
Step-by-step explanation:
The y coordinate of the point is 5, andthe x coordinate is a so substituting for these in the given equation:
3a - 4(5) = 6
3a - 20 = 6
3a = 26
a = 26/3
= 8 2/3
[tex]\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}[/tex]
here , we've been given a point with coordinates ( a , 5 ) and an equation ( 3x - 4y = 6 ).
To determine - the value of aCoordinate geometry deals with parameters related to points over cartesian plane , where a points , say G , has two coordinates x and y.
the coordinates are written as ( x , y ) , where x is the x coordinate or abcissa and y is the y coordinate or ordinate.
for getting the solution to the question asked , let us think of x as a and y as 5.
Now ,
substituting the values of x and y in the equation ,
[tex]3x - 4y = 6 \\ \implies \: 3(a) - 4(5) = 6 \\ \implies \: 3a - 2 = 6 \\ \implies \: 3a = 6 + 20 \\ \implies \: 3a = 26 \\ \implies \: a = \frac{26}{3} [/tex]
let's once check , if we've arrived at the correct result or no.
This can be done , by putting value of x as [tex]\frac{26}{3}\\[/tex] which is the value of a.
So ,
[tex]3x - 4y = 6 \\ \\ \implies \: \cancel3 (\frac{26}{\cancel3} ) - 4(5) = 6\\ \\ \implies26 - 20 = 6 \\ \\ \implies \: 6 = 6[/tex]
hence , verified !
Therefore ,
[tex]\bold\red{a = \frac{26}{3} }\\ [/tex]

What is the best approximation for the perimeter of a semicircle with a diameter of 35 inches?
Use 3.14 to approximate pi.
Answer:
Circumference shares the same concept with perimeter.
First, let's use the formula for the circumference of a full circle.
C = 2πr
Where 'π' stands for pi(22/7 or 3.14) and 'r' stands for the radius.
or
C = πd
Where 'π' represents pi(22/7 or 3.14) and 'd' stands for the diameter.
But, we are trying to find a semi-circle's circumference. So, what you would do is that you would divide the whole product of the formula by 2.
For this, I'll be using this formula C = πd. Though, since we are dividing by 2 we can apply that to the diameter and make it a radius in our formula.
So the 'd' in the formula will be 'r'.
Now, let's find the radius.
D/2 = R
So,
35/2 = 17.5
Use this in our formula:-
C = πr
C = 3.14(17.5)
C = 54.95 inches.

The letters in the word MATHEMATICIAN were put in a box. What is the chance of getting letter A?
Answer:
3/13
Step-by-step explanation:
There are a total of 13 letters in the word and 3 of them are A’s so 3/13 is the probability of getting an A.
The probability of getting the letter A is given by P ( A ) = 3/13
What is Probability?The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible
Probability = number of desirable outcomes / total number of possible outcomes
The value of probability lies between 0 and 1
Given data ,
Let the probability of getting the letter A be P ( A )
Now , the word is given as S = { "MATHEMATICIAN " }
The number of letters in the word S = 13 letters
The number of letter A in the word = 3 A's
So , probability of getting the letter A , P ( A ) = number of letter A in the word / number of letters in the word S
On simplifying , we get
The probability of getting the letter A , P ( A ) = 3/13
Hence , the probability is 3/13

Monica is a professional musician who practices clarinet for the same amount of
time every day. After she practices clarinet for 45 min on Wednesday, she has
finished 18% of her daily clarinet practice. How many more minutes does Monica
practice clarinet on Wednesday? Show your work.
Answer:
205 minutes
Step-by-step explanation:
If Monica has already practiced 18% of her time, we know that she has practiced [tex]\frac{18}{100}[/tex]. If this 18% corresponds to 45 min, we can have the following equation: [tex]\frac{18}{100} = \frac{45}{x}[/tex]. We can rearrange the equation to find the value of x by doing [tex]x = \frac{45 \cdot 100}{18} = 250[/tex], so she practices 250 min every Wednesday. If we subtract the time she has already practiced (45 min) we find out she still has to practice more 205 min.

If a coin is tossed, a die is rolled, and a candy is taken from
of 14 candies, 7 of which are red, what
8 the probability of getting a red candy, a heads, and an odd number on the die?
Answer:
⅛
Step-by-step explanation:
There are two sides of a coin which means that the profanity of getting one side of the coin is ½.
There are 14 candies in total of which 7 are red, meaning that the probability of getting a red candy is 7/14, which is the same as ½.
There are 6 sides to a die, of which 3 sides contain the odd numbers 1,3 and 5. This would mean that the probability of getting an odd number on the die is 3/6, which is the same as ½.
Now to work out the probability of getting a red candy, a heads and an odd number on the die, you have to times the probability of each together to get you final answer.
So it will be, ½×½×½=⅛
