Hello can someone help me I’m a little confused
Answer:
18 - 2x
Step-by-step explanation:
All you need to do is distribute the first expression, and then see which option matches the original expression
3( x + 6 ) - 5x
Distributive property
3x + 18 - 5x
Combine like terms
-2x + 18
The one similar to this one is the last one
18 - 2x
Hope this helped!

Answer:
17° and 73°
Step-by-step explanation:
For two complementary angles, the sum of angles is equal to 90 degrees.
Let other angles = x
First angle = 5+4x ...(1)
ATQ,
5+4x+x=90 ...(2)
Equation (1) and (2) shows the equations for the given problems.
5+5x=90
5x = 85
x = 17°
Other angle = 17
First angle = 5+4x
= 5+4(17)
= 73°
So, the other two angles are 17° and 73° respectively.

A boat can travel 496 km on 124 liters of fuel. How much fuel will it need to go 84 km?
____liters
Answer:
A boat would need 21 liters to cover the distance of 84 km.
Step-by-step explanation:
Given
A boat can travel 496 km on 124 liters of fuel.
To determine
How much fuel will it need to go 84 km?
It is stated that:
Distance covered in 124 liters of fuel = 496 km
Thus,
Unit rate = 496 km / 124 liters
= 4 km per liter
Thus,
The distance covered in 1 liter = 4km
In order to determine the distance covered in 84 km, all we need is to divide 84 km by 4.
i.e.
The fuel needed to go 84 km = 84 / 4 = 21 liters
Therefore, a boat would need 21 liters to cover the distance of 84 km.

the equation y = 73x + 146.53, where x represents the number of traffic tickets and y represents the cost of car insurance, determine the cost of car insurance if you had 9 tickets.
Answer:
803.53
Step-by-step explanation:
Cost of car insurance = 73 traffic tickets + 146.53
y = (73 × 9) + 146.53
y = 657 + 146.53
y = 803.53
Car insurance costs 803.53

Step-by-step explanation:
AE = 3x - 2 and EC = 2x + 3 then DB =
#5
Answer:
DB = 26
Step-by-step explanation:
Remember:
AE ≅ ECAC ≅ DB☆The equation in finding the value of x would be 3x - 2 = 2x + 3.
☆Let's solve the equation.
[tex] \: \: \: \: \: \: \: \: \: 3x - 2 = 2x + 3 \\ \frac{ - 2x \: \: \: \ = - 2x}{x - 2 = 3} \\ \frac{ \: \: \: \: \: + 2 = + 2}{x = 5} [/tex]
☆Now that we found the value of x, we are going to plug in for AE and EC.
[tex]AE ; \\ 3x - 2 \\ 3(5) - 2 \\ 15 - 2 \\ 13 \\ \\ \\ \\ and \\ \\ \\ \\ \\ EC; \\ 2x + 3 \\ 2(5) + 3 \\ 10 + 3 \\ 13[/tex]
☆AE and EC each measure 13. To find the length of AC, you will have to add AE and EC. [tex]13 + 13 = 26[/tex]
The length of AC is 26. And since we know that AC is congruent (equal) to DB, meaning they measure the same. DB length is also 26.

D is directly proportional to t2 When t = 4, D = 8 Find the positive value of t when D = 50
Answer: either 46 or 25 is your answer
Step-by-step explanation: Brainliest pls
Answer:
t = 10
Step-by-step explanation:
Proportions
D is directly proportional to t squared. This can be written as:
[tex]D = kt^2[/tex]
Where k is the proportionality constant. It can be calculated by substituting the given condition in the formula, when t=4, D=8:
[tex]8 = k4^2=16k[/tex]
Solving for k:
[tex]k=\frac{8}{16}=\frac{1}{2}[/tex]
Thus, the proportional relationship is:
[tex]\displaystyle D = \frac{1}{2}t^2[/tex]
When D=50, the value of t can be found by solving for t:
[tex]\displaystyle 50 = \frac{1}{2}t^2[/tex]
Multiplying by 2:
[tex]t^2=100[/tex]
Taking the square root:
[tex]t=\sqrt{100}[/tex]
The positive value of t is:
t = 10

At a local ice cream parlor, there are 6 different flavors of ice cream from which to select (strawberry, chocolate, vanilla, rocky road, mint chocolate chip, and peanut butter). Each ice cream sundae must include 2 different flavors of ice cream; what is the probability that the next customer's sundae will have vanilla and chocolate (in either order)
Answer:
1/30
Step-by-step explanation:
let, vanilla be the first ice cream.
hence, the probability of choosing vanila= 1/6
let, chocolate be the second ice cream.
hence, the probability of choosing chocolate=1/5
hence, the probability that the next customer's sundae will have vanilla and chocolate (in either order)= (1/6)×(1/5)
=1/30

If your gross monthly income will be $3,750, you need to determine the net pay for your monthly budget. Your monthly net pay is
Answer:
$2,989.12
Step-by-step explanation:
The correct answer to the given question is $2,989.12. The monthly net pay is $2,989.12, when the gross monthly income is $3,750.
The deduction from the gross income is almost 20.29%.
The gross income is multiplied by 20.29% and then the answer is deducted from the gross income which gives monthly net pay as a result
$3,750 * 20.29% = $760.875
$3,750 - $760.875 = $2,989.12
Your monthly net pay is $2,989.12

What is 76% of 30? show your work AWNSER ASAP
Answer: 22.8 because you calculate the percentage of number 30
Step-by-step explanation:
Answer:
22.8
Step-by-step explanation:
To find the percentage of a number, first change the percentage to a decimal and then multiply.
76% as a decimal is 0.76 (Divide the percentage by 100 to get decimal value)
30 x 0.76 = 22.8
(To multiply numbers when using decimals, first disregard the decimal altogether and multiply as normal - 30x76=2280 - then put in the decimal place at the end. In this case there were two digits after the decimal, so we place the decimal two digits from the right, turning 2280 to 22.80)

Find the length of dm in the given fig.
Answer:
[tex]DM=12[/tex]
Step-by-step explanation:
(Let the point where the altitude from [tex]D[/tex] intersects [tex]AB[/tex] be called as point [tex]E[/tex].) First, let's find the area of parallelogram [tex]ABCD[/tex]. The area of a parallelogram is simply [tex]b*h=bh[/tex], where [tex]b[/tex] is the parallelogram's base and [tex]h[/tex] is the parallelogram's height. If we let [tex]AB[/tex] and [tex]DE[/tex] be the base and height respectively, since we are already given their lengths, we know that the area of parallelogram [tex]ABCD[/tex] will be [tex]AB*DE=15*8=120[/tex].
Now, how does this information matter, you might ask? Well, we can take either [tex]AB[/tex] or [tex]CB[/tex] to be the base and either [tex]DE[/tex] or [tex]DM[/tex] to be the height. In this case, let's take the latter two options, as we are looking to find the length of [tex]DM[/tex].
Therefore, we know that the area of parallelogram [tex]ABCD[/tex] can also be found by calculating [tex]CB*DM[/tex]. Since we know the values of the area and [tex]CB[/tex], we can write the following equation to solve for [tex]DM[/tex]:
[tex]Area = CB*DM[/tex]
[tex]120=10*DM[/tex] (Substitute [tex]Area=120[/tex] and [tex]CB=10[/tex] into the equation)
[tex]\frac{120}{10}=\frac{10*DM}{10}[/tex] (Divide both sides of the equation by [tex]10[/tex] to get rid of [tex]DM[/tex]'s coefficient)
[tex]12=DM[/tex] (Simplify)
[tex]DM=12[/tex] (Symmetric Property of Equality)
Hope this helps!
