Based on the lesson, identify the first operation needed to solve the following equation. x/11 - 2 = 3 multiplication subtraction addition division
The number 2 should be added to both sides of the given linear
equation to enable the variable x be made the subject of the equation.
Response:
The first operation that needed to solve the equation is; AdditionWhich sequence of steps are needed to solve the given equation?The given equation is presented as follows;
[tex]\mathbf{\dfrac{x}{11} - 2} = 3[/tex]
The solution of the above equation van be found by making x the
subject of the equation.
Removing the 2 from the left hand side of the equation will isolate the [tex]\dfrac{x}{11}[/tex]
, from which the value of x can be found by multiplying by 11.
First operation;
To remove the 2, we have;
2 - 2 = -2 + 2 = 0, adding 2 to both sides of the equation gives;[tex]\dfrac{x}{11} - 2 \mathbf{+ 2 }= 3 + 2[/tex]
[tex]\dfrac{x}{11} + 0 = 3 + 2 = 5[/tex]
[tex]\dfrac{x}{11} = 5[/tex]
Second operation;
[tex]\dfrac{x}{11} \times 11 = 5 \times 11 = 55[/tex]
x = 55
The first operation that needs to be needed to solve the given equation
is therefore;

IM TIMED HELP PLS , solve the system of equations using substitution method , y = 2x + 8 , y = 4x - 2
Answer:
x=5, y=18
Step-by-step explanation:
y=2x+8
x= (y-8)/2
Substitute in second equation,
y= 4((y-8)/2) -2
y= 2(y-8)-2
y= 2y-16-2
16+2=2y-y
18=y
Replace y value in first equation to find x,
18= 2x+8

Mrs. Santos can cook the menu for a party in 4 hours. Mr. Salonga can work to fast as she can. If they work together to cook, how many hours will it cake them to finish cooking.
2 hours and 40 minutes
Step-by-step explanation:
Let a be Mrs Santos
Let b be Mr. Salonga
Mrs. Santos can cook the menu for a party in 4 hours
a = 4 hours
Mr. Salonga can work twice as fast as she can.
b = 2 ( 4) = 8 hours
The word time formula is
1/a +1 /b = 1/t
Where t is the total time
Substitute the values
1/4 + 1/8 = 1/t
1/4 + 1/8 = 2/8 + 1/8 = 3/8
Therefore
3/8 = 1/t
Doing cross multiplication
3*t = 1 * 8
3t = 8
Dividing both sides by 3
3t/3 = 8/3
t = 8/3 hours
t =2 \frac{2}{3}t=2

Suppose that COP and TOD are vertical angles, m COP = 11x - 17
and m TOD = 9x + 11.
Determine the Measure of COD
Determine the measure of POT
Answer:
Step-by-step explanation:
If COP and TOD are vertical angles, then they are equal to each other because vertical angles are equal.
m COP = m TOD
Given
COP = 11x - 17
TOD = 9x + 11.
Substitute:
11x-17 = 9x+11
11x-9x = 11+17
2x = 28
x = 28/2
x = 14
Get <COD
<COP = 11(14)-17
<COP = 154-17
<COP = 137
<COD = 180-<COP
<COD = 180-137
<COD = 43°
Similarly:
<POT = 180 - <TOD
<POT = 180 - [9(14)+11]
<POT = 180 - 137
<POT = 43°

Find the value of x and y that satisfy both of the equalities x /y= 2/3 and y/12 = 3/4.
Answer:
x=6;y=9
Step-by-step explanation:
First you try to find y in the second equation --> y/12=3/4
You divide 12 by 4 to see how many times y/12's denominator and numerator is bigger. 12/4 is 3, so to find y you multiply 3*3. so 9/12=3/4. To check this, you multiply 3 on each side of the fraction -->
3*3=9 4*3=12.
Then, you can just put y into the first equation, which is x/y=2/3. Pluck that in, and you get x/9=2/3. Do the same thing you did in the first step, and you should get 6/9=2/3. Hope this helped :)
Answer:
x=6; y=9

Question 3/3 Devon opened a bank account with $225. He saves $25
per month. What is the least amount of months it will take him to save $750?
Answer:
21 Months
Step-by-step explanation:
If he already has $225, we can do 750 - 225 to get 525. $525 represents how much more money he needs to reach his goal of $750. So we can do 525 divided by 25, since that is how much he makes per month, giving us 21. 21 is how many months it will take until he gets to $750 without spending anything.

At the restaurant, the cost of the meal before tax was
$40. The tax is 8.5%, and Sheri wants to leave at least
an 18% tip. Explain how to approximate the total cost of
the meal.
Answer:
so you add then multiply then subtract
Step-by-step explanation:
Answer:
First we estimate the percent's. 8.5% - 10%, 18% - 20%. Then we do the equation. If you add percent's you get 30% multiply that by 40 and you get 12. Add that to you problem and you get $52.
Step-by-step explanation:
Since the tax and gratuity were 4 and 8 dollars you can just add those up to the 40, but I did it another way.
This is the sample response if you want a better explanation.
The gratuity is about 20% of $40, which is $8. The tax is about 10% of $40, which is $4. So, the total cost is about $40 + $8 + $4 = $52.

6(1+x)+x=-14
Please help solve for x
Answer:
X is equal to -10
Step-by-step explanation:
#1. Multiply 6 to (1+x). Doing this makes this equation: 6+x+x=-14
#2. Move 6 to the other side of the equation, to the side of the answer and change its abbsolute value. Doing this will make x+x=-14-6.
#3. Simplify both sides. 2x=-14-6 ----> 2x=-20
#4. divide -20 by 2, this equals -10. x is equal to -10. WooHoo!
Answer:
Answer x=-[tex]\frac{20}{7}[/tex]
Step-by-step explanation:
6(1+x)+x=-14
(multiply bracket with 6)
6+6x+x=-14
(-6 for both sides)
6x+x=-20
(add x terms together)
7x=-20
(divide by 7 for both sides)
x=-[tex]\frac{20}{7}[/tex]

Answer:

Step-by-step explanation:
because the straight line is 180 so if you add 35+55=90 and 90+90=180
Answer:
35°
Step-by-step explanation:
What I did was look at ∠ABC and know that collinear is a straight line, and that a straight line is equal to 180°. Then I saw that ∠ABD was a right angle or 90° and that ∠BCE was equal to 55°, so I added those 2 together and got 145°. then I subtracted that from the 180°. because that is what a straight line equals and I got 35°. So, I would say ∠DBE is equal to 35°.
