Step-by-step explanation:
Sakal and Roy each have a sack of 50 apples.
All apples are either red or green.
Sakal = x
Roy = y
If Sakal has three times as many red apples as Roy does
x = 3y
and half as many green apples as Roy does,
x = 1/2y
how many red apples does Sakal have?
2{x+8}+5{x-1}=60 answer
Answer:
x=7
Step-by-step explanation:
2{x+8}+5{x-1}=60
Distribute
2x+16+5x-5 = 60
Combine like terms
7x +11 = 60
Subtract 11 from each side
7x+11-11 = 60-11
7x = 49
Divide each side by 7
7x/7 = 49/7
x = 7

To purchase $14,500 worth of restaurant equipment for his business, Hans made a down payment of $1800 and took out a business loan for the rest. After years of paying monthly payments of $562.88. , he finally paid off the loan.
Answer:
hello your question is incomplete below is the complete question
To purchase $14,500 worth of restaurant equipment for his business, Hans made a down payment of $1800 and took out a business loan for the rest. After 2 years of paying monthly payments of $562.88. , he finally paid off the loan. What was the total amount Dean ended up paying for the equipment ( including the down payment and monthly payments )
answer: $15309.12
Step-by-step explanation:
Initial cost of equipment = $14500
Down payment = $1800
cost of equipment = 14500 - 1800 = $12700
Monthly payment = $562.88
Therefore payment made after 2 years = ( 562.88 * 24 ) = $13509.12
Total amount paid by Dean for the equipment
= down payment + monthly payments
= $1800 + $13509.12
= $15309.12
Factor completely: 2x^3-12x^2+18x
Answer:
2x(x - 3)²
Step-by-step explanation:
We can simplify this a lot by first factoring 2x out of each term:
2x³ - 12x² + 18x
= 2x(x² - 6 + 9)
We can then factor the trinomial fairly easily, as it's a perfect square:
= 2x(x - 3)²
solve the problem:
x + 4 = 10
Answer: 6
Step-by-step explanation: The way to solve this problme is to move backwards. Instead of adding you would subtract the number after the equal sign and whatever number before. It's kind of like a fact family!
10-4=6 so the answer is 6.
I hope this help you out, have an awesome day! :)

Write and solve an equation to answer the question. 14 is what percent of 70?
Answer:
20%
Step-by-step explanation:
An equation is 14=x/100*70 or 14=(x%)*70, either one works
solve for x:
14=x/100*7014/70=x/100 (Divide each side by 70)1/5=x/100 (Simplify 14/70)100/5=x (Multiply each side by 100 to isolate x)x=20 (Simplify 100/5)20% (Rewrite as a percent)hope this helps!!
is there an error in the work and is the answer extraneous? if so why?
Answer:
x = 4
Step-by-step explanation:
log₃[1 + log₃(2ˣ - 7)] = 1
log₃[1 + log₃(2ˣ - 7)] = log₃(3)
1 + log₃(2ˣ - 7) = 3
log₃(2ˣ - 7) = 2
log₃(2ˣ - 7) = log₃(3)²
2ˣ - 7 = 9
2ˣ = 9 + 7
2ˣ = 16
2ˣ = 2⁴
x = 4
By putting x = 4 in the original equation,
log₃[1 + log₃(2⁴ - 7)] = 1
log₃[1 + log₃(16 - 7)] = 1
log₃[1 + log₃(9)] = 1
log₃[1 + log₃(3)²] = 1
log₃[1 + 2] = 1
log₃[3] = 1
1 = 1
Therefore, x = 4 is not the extraneous solution and there is no error in your answer.

Find the slope of the line.
A. 3
B. [tex]-\frac{1}{3}[/tex]
C. –3
D. [tex]\frac{1}{3}[/tex]
Answer:
The slope of the line 3.
Step-by-step explanation:
The line is going through 3. Although it is not -3, because if the line is sloping upward from left to right, then the slope is positive (+). If the line is sloping downward from left to right, the slope is negative (-).

Hint 1: Find the direction cosines of AB and BC. Then take their dot product. This will give the cosine of the angle between AB and BC.
Hint 2: The Direction Cosines of PQ, P(x1,y1,z1) and Q(x2,y2,z2), are (±x2−x1(x2−x1)2+(y2−y1)2+(z2−z1)2√,±y2−y1(x2−x1)2+(y2−y1)2+(z2−z1)2√,±z2−z1(x2−x1)2+(y2−y1)2+(z2−z1)2√)
Edit: The Dot Product works iff the lines intersect.
B is the intersect point , doesn't matter if it's in 2D or 3D – Ali Apr 28 '18 at 5:52

Lines in dimension three do not have to intersect. We find their direction vectors to see if they are parallel.
Note that
AB→=<x2−x1,y2−y1,z2−z1>
and
BC→=<x3−x2,y3−y2,z3−z2>
These vectors are the direction vectors are your lines.
The dot product
AB→.BC→
along with the norms of these vectors determine the angle between the lines if they intersect at all.
cosθ=AB→.BC→||AB||.||BC||

Width: 10

YO 10 or 22 points can somebody pls help me I’m stuck. Solve each inequality for x then graph your answer on a number line. Remember when you divide by a negative you have to switch the inequality symbol. Pls pls help me :(
Answer:
x<5
Step-by-step explanation:
−2(x−7)>4
Step 1: Simplify both sides of the inequality.
−2x+14>4
Step 2: Subtract 14 from both sides.
−2x+14−14>4−14
−2x>−10
Step 3: Divide both sides by -2.
−2x ÷ −2 > −10 ÷ −2
x<5

When rounding to the nearest hundred thousand what is the greatest whole number that rounds to 400,000
Answer:
449,999
Step-by-step explanation:
Given that:
Greatest whole number that round to 400,000 when rounding to the nearest hundred thousand :
To obtain the greatest whole number which rounds to 400,000, the whole number is greater Tha 400,000 and its 10 thousand digit in the number or value to be rounded must be lesser than 5.
The value would be 449,999 ; here z the 10 thousand value which is 4 is rounded to zero since it is not up to 5 and the subsequent digits also rounded to 0 to give ;
400,000 (nearest hundred thousand).
You are organizing a school banquet. You spend $82 on decorations. Dinner will cost $13 for each person that attends. In the equation y=13x+82, y is the total cost of the banquet for x people. Complete the solution (69,?) to find the cost for 69 people.
Answer:
(69,979)
Step-by-step explanation:
In the coordinates, x is represented as 69. We can now insert this into the equation.
y = 13x + 82
Now to insert x.
y = 13(69) + 82
Now we can multiply 13 by 69.
13*69 = 897
Now fix the equation.
y = 897 + 82
Now add to get our y.
897 + 82 = 979
Substitute into the equation.
y = 979
And there is our answer. We now need to put this into the coordinates.
And we get our final answer of (69,979).
Hope this helps. Have a nice day.
I took a picture of the problem.
Step-by-step explanation:
[tex] - {3}^{2} m {n}^{5} m {n}^{2} {m}^{6} = \\ = - 9 {m}^{8} {n}^{7} [/tex]
find the value for m
-10 + 59 = 5m = 7 + 3m
-10+59=5m=7+3m
49=5m=7+3m
49-7=5m-3m
m=42/2
m=21
Answer:
21
Step-by-step explanation:
-10+59 = 5m = 7 + 3m
49 = 5m = 7 + 3m
49 - 7 = 5m - 3m
42 = 2m
42/2 = m
m= 21
find the slope and y-intercepts of the line below & write the equation of the line.
Answer:
m=3 b=-2 y=3x-2
Step-by-step explanation:
The slope/m is 3 because the rise is 3 and the run is 1. Rise over run and you get 3/1 also known as 3.
The y-intercept point/b is -2 because you can look at the graph and the point where the line touches the y-axis is the y-intercept/b
The equation is written in the format of y=mx+b so y and then m is the slope then add x after the slope, then write the y intercept.
