Answer:
18x + 4y + 3
Step-by-step explanation:
8x + 10x - 5y + 3 + 9y(8x + 10x) + (-5y + 9y) + (3)18x + 4y + 3Therefore, the answer is 18x + 4y + 3.
Answer:
[tex]18x+4y+3[/tex]
Step-by-step explanation:
Add the like terms.
[tex]8x+10x=18x[/tex]
[tex]-5y+9y=4y[/tex]
⇒ [tex]18x + 4y+3[/tex]

Last month, Ben rode his bike 24 miles a week for 4 weeks. This month, Ben ride his bike 28 miles a week for 3 weeks. How many miles did Ben ride his bike in all?
Answer:
180
Step-by-step explanation:
Multiply 24x4=96
Then, multiply 28X3=84
Finally add the 2 for a total of 180
Answer:
180 miles
Step-by-step explanation:
Basically, if he rode his bike 24 miles each week and he rode it for 4 weeks you would multiply 24 times 4, which gives you 96 miles. Then, you would do the same for the 28, 28 times 3 gives you 89 miles. Lastly, you add it all up. 96+89= 180 miles

Answer:
(d) 9
Step-by-step explanation:
The relation you're supposed to apply here is ...
an exterior angle of a triangle is equal to the sum of the remote interior angles.
__
The exterior angle is 17x+7, and it is equal to the sum of the two marked angles inside the triangle.
17x +7 = 13x +3 +40
4x = 36 . . . . . . . . . . . . . subtract 13x+7 from both sides
x = 9 . . . . . . . . . divide both sides by 4

Answer:
x² +2/3x -1/9 = 0
Step-by-step explanation:
The quadratic with roots p and q can be written as ...
(x -p)(x -q) = 0
x² -(p+q)x +pq = 0
For p=(-1-√2)/3 and q=(-1+√2)/3, we have ...
p +q = (-1-√2)/3 +(-1+√2)/3 = -2/3
pq = ((-1-√2)/3)((-1+√2)/3) = (1 -2)/9 = -1/9
Then the quadratic is ...
x² +2/3x -1/9 = 0
Can someone explain how you do this and not only give me a answer?
Got it! Here you go!
Step-by-step explanation:
It seems you already know that you need to do 17-2/3(not two thirds, just over 3.)
The horizontal line means divide, so you will be dividing by 3. First, though,, you do...
17-2(which is 15)
and then divide it by 3.
15/3=5
Your answer is 5.
I hope I helped! Have a great day.
Cait can bike 32 miles in the same amount of time that Carl can bike 24 miles. If Cait bikes 2 mph faster than Carl, how fast does Cait bike?
Let t = time in hrs for both to go 32 mi
Let s = Carl's speed in mi/hr
s + 2 = Caits speed in mi/hr
------------------------------------------------------------
Carl's equation:
(1) 24 = s · t
Cait's equation:
(2) 32 = (s+2) · t
-----------------------------------
(2) 32 = s · t + 2t
and
(1) s = 24/t
Plug (1) into (2)
(2) 32 = (24/t) · t + 2t
(2) 32 = 24 + 2t
(2) 2t = 8
(2) t = 4
and
(1) s = 24/4
(1) s = 6
The speed of Cait is 8 mph
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them. Variables are the name given to these symbols because they lack set values. We frequently observe constant change in specific variables in our day-to-day situations. But the need to depict these shifting values is ongoing. These values are frequently represented in algebra by symbols such as x, y, z, p, or q, and these symbols are known as variables. In order to determine the values, these symbols are also subjected to different addition, subtraction, multiplication, and division arithmetic operations.
Let x be the time in hours for both to go 32 miles
Let y be Carl's speed
Then Caits speed is = y+ 2
So, Carl's equation:
x y= 24
and, Cait's equation:
32 = (y+2) · x
32 = xy + 2x...............(1)
and, y = 24/x
Put the above value in equation (1)
(24/x) x + 2x = 32
2x+ 24 = 32
2x= 8
x=4
Also, y= 24/x= 24/4 = 6
Hence, speed of Cait is 8 mph

Maria import special clay pots from Brazil. A shipment of 50 pots cost her $350. She then sells the pots at local fairs and art shows. On her last shipment she made a profit of $750. (1) What is the cost of 1 clay pot? (2) what is the total amount of sell in order to make the profit? (3) How much does she need to sell each pot in order to make the profit?
Answer:
Q 1) 7$ Q 2) 50 Q 3) 15$
Step-by-step explanation:
1) The cost of 1 claypot = $7
2) Total amount sold to yield the given profit = $1100
3) Amount to sell each pot to make the given profit = $22
We are given that;
Cost of 50 pots = $350
1) Since 50 pots costs $350, the cost of one pot will be;Cost of 1 clay pot = 350/50 = $7 per clay pot
2) She made a profit of $750 on the 50 pots.This means amount she sold in order to make the profit will be;
$350 + $750 = $1,100
3) Since total amount she sold to make the profit is $1,100, then amount each pot was sold to yield that profit on the 50 clay pots will be;1100/50 = $22 per pot

What is the problem for this Problem?
Answer:
Negative: (-∞,-3] and [1/2,-∞)
Positive: [-3,1/2]
Step-by-step explanation:
The derivative is the instantaneous rate of change at any given point for a function. Given this we know that anywhere the function is in the positive or negative direction, the derivative will also be in the positive or negative direction. We also know that wherever there is a peak or a trough, there will be no slope and it signifies a change in direction. For this function, this means the direction changes at -3 and 1/2.
