What is 3(2x +7x - 5 )
Answer:
x = 15/27
Step-by-step explanation:
3(2x + 7x - 5)
Distribute the 3
6x + 21x - 15
Combine like terms
27x - 15 = 0
27x = 15
x = 15/27
Answer:
27x - 15 is your expression
Step-by-step explanation:
3 x 2x = 6x and 3 x 7x = 21x so 21x + 6x = 27x and 3 x 5 = 15 so 27x - 15 is your expression

I need help 6x-2y=10 x-2y=-5 solve by elimination
[tex] \begin{cases} 6x - 2y = 10 \\ x - 2y = - 5 \end{cases}[/tex]
Solve the system of equations by eliminating either x-term or y-term. We will eliminate the y-term as it is faster to solve the equation.To eliminate the y-term, we have to multiply the negative in either the first or second equation so we can get rid of the y-term. I will multiply negative in the second equation.
[tex] \begin{cases} 6x - 2y = 10 \\ - x + 2y = 5 \end{cases}[/tex]
There as we can get rid of the y-term by adding both equations.
[tex](6x - x) + ( - 2y + 2y) = 10 + 5 \\ 5x + 0 = 15 \\ 5x = 15 \\ x = \frac{15}{5} \longrightarrow \frac{ \cancel{15}}{ \cancel{5}} = \frac{3}{1} \\ x = 3[/tex]
Hence, the value of x is 3. But we are not finished yet because we need to find the value of y as well. Therefore, we substitute the value of x in any given equations. I will substitute the value of x in the second equation.
[tex]x - 2y = - 5 \\ 3 - 2y = - 5 \\ 3 + 5 = 2y \\ 8 = 2y \\ \frac{8}{2} = y \\ y = \frac{8}{2} \longrightarrow \frac{ \cancel{8}}{ \cancel{2}} = \frac{4}{1} \\ y = 4[/tex]
Hence, the value of y is 4. Therefore, we can say that when x = 3, y = 4.
Answer Check by substituting both x and y values in both equations.First Equation
[tex]6x - 2y = 10 \\ 6(3) - 2(4) = 10 \\ 18 - 8 = 10 \\ 10 = 10 \longrightarrow \sf{true} \: \green{ \checkmark}[/tex]
Second Equation
[tex]x - 2y = - 5 \\ 3 - 2(4) = - 5 \\ 3 - 8 = - 5 \\ - 5 = - 5 \longrightarrow \sf{true} \: \green{ \checkmark}[/tex]
Hence, both equations are true for x = 3 and y = 4. Therefore, the solution is (3,4)
Answer[tex] \begin{cases} x = 3 \\ y = 4 \end{cases} \\ \sf \underline{Coordinate \: \: Form} \\ (3,4)[/tex]
20 + 60 ÷ 5 + (9 - 4)2
Answer:
42
Step-by-step explanation:
20 + 60 ÷ 5 + (9-4)2
Use PEMDAS to solve this equation, so first solve what is in the parentheses
20 + 60 ÷ 5 + (5)2
Since there are no exponents, next solve the multiplication
20 + 60 ÷ 5 + 10
Next is division
20 + 12 + 10
Finally, addition

Find A, B so that y = A sin(2) + B cos(2) is a solution to the differential equation
4y'' +y' + 5y = 2 cos(x).
A=
BE
Submit Question
If y = A sin(x) + B cos(x), then
y' = A cos(x) - B sin(x)
y'' = -A sin(x) - B cos(x)
Substitute these into the ODE:
4y'' + y' + 5y = 2 cos(x)
4 (-A sin(x) - B cos(x)) + (A cos(x) - B sin(x)) + 5(A sin(x) + B cos(x)) = 2 cos(x)
(-4A - B + 5A) sin(x) + (-4B + A + 5B) cos(x) = 2 cos(x)
(A - B) sin(x) + (A + B) cos(x) = 2 cos(x)
Then
A - B = 0
A + B = 2
Adding these equation gives
(A - B) + (A + B) = 0 + 2
2A = 2
A = 1 → B = 1
Emily surveyed 300 of the students in her school about their favorite color. 93 students said their favorite color was purple. What percentage of the surveyed students said their favorite color was purple?
Answer:
31%
Step-by-step explanation:
93/300=0.31
0.31=31%
The percentage of the surveyed students said their favorite color was purple will be 31%.
What is mean by Percentage?
A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
Given that;
Total number of students = 300
And, There are 93 students said their favorite color was purple.
Now,
The percentage of the surveyed students said their favorite color was purple is find as;
Total number of students = 300
And, There are 93 students said their favorite color was purple.
So, Percent of the surveyed students said their favorite color was purple is;
Percent = 93 / 300 x 100
= 31%
Thus, The percentage of the surveyed students said their favorite color was purple will be 31%.

if lana bought cigarettes for $3.00/pack X 7 packs/week X 52 weeks/year X 10 years, how much would it be?
EASY QUESTION OF THE DAY (whoever answers first gets brainly!)
Answer:
she would be spening over a thousand dollars
Step-by-step explanation:
Asnwer:
10,920$
Step-by-step explanation:
So if 3.00$ is for one pack and she wants 7 packs then it would be 21$.
But if we also multiply it by 52 weeks then that would be 1,092$.
Then if she's buying that for 10 years then we multiply 10 x 1,092$ which would equal 10,920$

7. Marie can make 12 small mango pies for every 10 mangoes. How many pie
A. Marie can make 30 pies.
C. Marie can make 50 pies
B. Marie can make 40 pies.
D. Marie can make 60 pies
sorry putol po kasi eto
Answer:
D. Marie can make 60 pies.
Step-by-step explanation:
In this problem, we know that amount of small mango pies is directly proportional to the amount of mangoes. The amount needed for preparing an amount of pies is calculated by simple rule of three:
A. Marie can make 30 pies.
[tex]x = \frac{10\,mangoes}{12\,pies}\times 30\,pies[/tex]
[tex]x = 25\,mangoes[/tex]
25 mangoes are required for producing 30 pies.
B. Marie can make 40 pies.
[tex]x = \frac{10\,mangoes}{12\,pies}\times 40\,pies[/tex]
[tex]x = 33.333\,mangoes[/tex]
34 mangoes are required for producing 40 pies.
C. Marie can make 50 pies.
[tex]x = \frac{10\,mangoes}{12\,pies}\times 50\,pies[/tex]
[tex]x = 41.667\,mangoes[/tex]
42 mangoes are required for producing 50 pies.
D. Marie can make 60 pies.
[tex]x= \frac{10\,mangoes}{12\,pies}\times 60\,pies[/tex]
[tex]x = 50\,mangoes[/tex]
50 mangoes are required for producing 60 pies.
The complete statement is: Marie can make 12 small mango pies for every 10 mangoes.How many pies can she make with 50 mangoes.
Hence, correct answer is D.

The temperature was recorded at the same time each day,
a)
Which temperature was the warmest?
b)
Which temperature was the coldest?
c)
How much colder was it on Thursday than on Saturday?
d)
On Sunday the temperature was 5°C lower than on Saturday.
What was the temperature on Sunday?
Answer:
a) The warmest temperature will be the one where the value of the temperature is the largest, in the table we can see that the largest temperature is 3°C on Saturday.
Then the largest temperature was on Saturday, and it was 3°C
b) Which temperature was the coldest?
Now we need to look at the smallest temperature (or the largest negative temperature). In the table we can see that the smallest temperature is -6°C on Friday.
Then the smallest temperature is -6°C.
c) On Thursday the temperature was -1°C
On Saturday the temperature was 3°C
The difference between the temperatures is:
-1°C - (3°C) = -4°C
This means that Thursday was -4°C colder than on Saturday.
d) On Sunday, the temperature was 5°C lower than on Saturday.
On Saturday the temperature was 3°C, then the temperature on Sunday is:
T = 3°C - 5°C = -2°C
The temperature on Sunday is -3°C.
