You purchase a remote-controlled drone for d dollars. Your friend purchases a drone that costs $35 more than your drone. Your brother purchases a drone that costs three times as much as your friend's drone. Write and simplify an expression that represents the cost (in dollars) of your brother's drone.
Answer:
[tex]Brother = 105 + 3d[/tex]
Step-by-step explanation:
Given
[tex]Drone = d[/tex]
Friend = $35 more expensive than yours.
Brother = 3 * as much as your friend
Required
Write an expression for the cost of your brother's drone
I'll solve by analysing the question one sentence after the other
You:
[tex]Drone = d[/tex]
Your friend:
Friend = $35 more expensive than yours.
This means
[tex]Friend = 35 + You[/tex]
Substitute d for You
[tex]Friend = 35 + d[/tex]
Your brother:
Brother = 3 * as much as your friend
This means:
[tex]Brother = 3 * Friend[/tex]
Substitute 35 + d for Friend
[tex]Brother = 3 * (35 + d)[/tex]
Open bracket
[tex]Brother = 3 * 35 + 3*d[/tex]
[tex]Brother = 105 + 3d[/tex]

one number is equal to 4 times another number. their difference is 12. find the numbers
Answer:
[tex]x=16 \ \ and \ \ y=4[/tex]
Step-by-step explanation:
Suppose the numbers are x and y
One number say x is equal to 4 times another number say y
[tex]x=4y[/tex] ---------------- (1)
Their difference is 12
[tex]x-y=12[/tex] ------------(2)
Put x=4y in equation (2)
[tex]4y-y=12[/tex]
[tex]3y=12\\y=4[/tex]
Put y=4 in equation (1)
[tex]x=4(4)\\x=16[/tex]
How am I supposed to do this?
For literal equations you do not necessarily need a numerical answer. You just need to get the variable you are supposed to solve for on one side of the equation by itself. To do this you will follow the same steps you do when you normally solve for x (or any other variable)
#9-Step by step
Q=25[tex]\pi[/tex]h
divide 25[tex]\pi[/tex] on both sides of the equation
Q/25[tex]\pi[/tex]=h
h=Q/25[tex]\pi[/tex]
Since his can't be simplified any further this is your answer
#11. y=7m+6
First subtract 6 over to the other side
y-6=7m
then divide the 7 over
(y-6)/7=m
m=(y-6)/7
#13 A=(Z+7)3
Divide the three over to the other side of the equation
A/3=Z+7
Now the 7 is free to be subtracted from both sides
(A/3)-7=Z
#17. (2x/5)-9=6
First add 9 to both sides
2x/5=6+9
2x/5=15
Multiply both sides of the equation by 5
2x=5(15)
2x=75
Divide by 2
x=75/2
x=37.5
Help me!! I’m very bad at rounding numbers!! What’s 366 rounded to the hundreds place?? help ASAP!
Answer:
400
Step-by-step explanation:
Tge 6 in the tens place is greater than 5, so you round the 3 up to 4.
If the number that determines where you round is 5 or more, round up.
So 366 rounded to the hundreds place is 400.
The answer is 400.

Determine whether the triangles are similar. or not.
If similar, state how.
A. similar, AA
B. similar, sss
C. Similar, SAS
D. Not similar
Answer:
A
Step-by-step explanation:
We know that ∠[tex]ABE[/tex] ≅ ∠[tex]DBC[/tex] because they are vertical angles, so that's one pair of congruent angles. However, we can't compare ∠[tex]BAE[/tex] and ∠[tex]DCB[/tex] as they have different measures, so we'll have to find the measure of either ∠[tex]AEB[/tex] or ∠[tex]BDC[/tex]. Let's go with the former. Using the fact that the sum of the measures of the interior angles of a triangle is [tex]180[/tex]°, we know that [tex]m[/tex]∠[tex]AEB=180-(53+42)=180-95=85[/tex]°. Now, we know that ∠[tex]AEB[/tex] ≅ ∠[tex]DCB[/tex] because their measures are equal. That's another pair of congruent angles. Therefore, the angles are similar by [tex]AA[/tex]. Hope this helps!

Step-by-step explanation:
Find the value of p and q such that
2x^2 - 4x + 3= 2 (x-p)^2 + q
PLEASE ANSWER!!!
Answer:
The values of p and q such that 2·x² - 4·x + 3 = 2·(x - p)² + q, are;
p = 1, q = 1
Step-by-step explanation:
The given equation are;
2·x² - 4·x + 3 = 2·(x - p)² + q
By expanding the right hand side of the equation, we have;
2·x² - 4·x + 3 = 2·(x - p)² + q = 2·x² - 4·p·x + 2·p² + q
2·x² - 4·x + 3 = 2·x² - 4·p·x + 2·p² + q
Comparing the coefficient of x in both equations, gives;
2·x² + (- 4)·x + 3 = 2·x² + (- 4·p)·x + 2·p² + q
-4 = -4·p
∴ p = -4/(-4) = 1
p = 1
Comparing only the constant terms (terms not multiplied by "x" or "x²"), we get;
3 = 2·p² + q
Substituting the value for "p" obtained above (p = 1 ) in the previous equation, we get;
3 = 2 × 1² + q = 2 + q
∴ q = 3 - 2 = 1
q = 1.
On number 12 I need hell
Answer:
1,600 dollars
Step-by-step explanation:
The easiest way to solve it is to find the dollar for 1 percent.
Since 480 accounts for 30% of the whole thing, we can do 480 divided by 30 to get 16 as 1 percent. This means that 16 times 100 percent would give us the total money spent, giving us 1,600 as our answer.

Tara is graphing the equation 4x + 2y = 10. Which of these shows the correct equation in slope-intercept form, slope, and y-intercept?
Question 2 options:
y = –2x + 5
slope = –2
y-intercept = 5
y = 2x + 4
slope = 2
y-intercept = 4
y = –4x + 5
slope = –4
y-intercept = 5
y = 4x + 5
slope = 4
y-intercept = 5
Answer: y = -2x + 5
Step-by-step explanation:
y = -2x + 5
slope = -2
Slope intercept form of equation of line is given by y = mx + c
where m is the slope of line
c is the y intercept i.e point where given line intersect y axis.
________________________________________________
given equation 4x + 2y = 10
we have to re-write this equation in form y = mx + c
4x + 2y = 10
subtraction 4x from LHS and RHS
4x + 2y - 4x= 10 - 4x
2y = 10- 4x
we have to eliminate 2 from y for that we
divide LHS and RHS by 2 we
2y /2 = 10/2- 4x/2
y = 5 - 2x
rearranging it in y = mx+c form
y = -2x + 5
thus, m = -2 , c = 5
Answer:
y=-2x+5, slope= -2, y-intercept= 5 (so, first option)
Step-by-step explanation:
y=mx+b. m is the slope, and b is the y-intercept. to get the equation to the slope intercept form, you get y by itself- subtract 4x from both sides and then divide by 2 on both sides.
what is the output of , y=5x-3 when x is 5
Answer:
The output is 22
Step-by-step explanation:
So, you are going to want to plug in 5 for x, therefore-
y = 5(5) - 3
Solve from there
y = 25 - 3
y = 22
Answer:
x = 5 and y = 22
Step-by-step explanation:
y = 5 x − 3
y = ( 5 ) ( 5 ) − 3
y = 22

Halona walks 1.93 kilometers to a neighbor’s house in 23 minutes. Assuming she walks at a constant speed, write a proportion that represents how many kilometers,y, Halona can walk in x minutes. Then solve your proportion for y.
Answer:
proportion: 1.93/23 = y/x
solve for y: y = x(0.083913)
Step-by-step explanation:
The required relationship of the proportionality is y = 0.08 x.
Given that,
In 23 minutes, Halona travels 1.93 kilometers to a neighbor's home. assuming she moves at a steady pace.
How many kilometers, y, Halona can walk in x minutes, expressed as a proportion. After that, find y using your percentage.
The relationship between two or more sets of values—whether they are directly proportional or inversely proportional to one another—is referred to as proportionality.
Here,
according to the question,
y ∝ x
y = kx
Where k is the constant of the proportionality,
at x = 23, y = 1.93
1.93 = 23 k
k = 1.93/23
k = 0.08
Put k in the proportionality equation,
y = 0.08k
Thus, the required relationship of the proportionality is y = 0.08 x.
