what is the slope of the line represented by 5x-12y=24?
Answer:
Step-by-step explanation:
5x - 12y = 24
-12y = -5x + 24
12y = 5x - 24
y = 5/12x - 2
slope is 5/12

The answer is E
Dan,Gordon and malachy share some sweets in the ratio 2:2:5. Dan gets 24 sweets.How many did malachy get?
Answer:
60 sweets
Step-by-step explanation:
The total ratio = 2 + 2 +5 = 9
Let x = total sweets shared
Dan got 2/9 of x. This is equal to 24
the equation for this is - [tex]\frac{2}{9}[/tex] × x = 24
to solve for x, divide both sides by [tex]\frac{9}{2}[/tex]
x = 108 = total sweet shared
sweets malachy got = [tex]\frac{5}9}[/tex] x 108 = 60 sweets

If f(x)=2x-4 and x=4
Solve for f(x):
Answer:
dfyrexbjnyyfdc bgg hi ytdxvjud
Answer:
4
Step-by-step explanation:
f(x)=2x-4
f(x)=2(4)-4f(x)=8-4f(x)=4Just plug in 4 into x. If you get confused on what f(x) means, it basically is the output value or the y value. So when plugging in the number for f(x), I recommend not worrying about the symbol f(x) too much.

Use your knowledge on the triangle proportionality theorem to find the missing side length indicated. Be sure to explain the proportion you used.
Answer:
? = 4.29
Step-by-step explanation:
Remark
Let x be the question mark. You get the proportionality by using the dimensions of the little triangle to the dimensions of the large triangle.
Equation
14/(14+ 4) = 15/(x + 15) Combine like terms on the left
14/18 = 15/(x + 15) Cross multiply
14*(x + 15) = 18 * 15 Simplify the right
14(x + 15) = 270 Divide by 14
x + 15 = 270 / 14
x + 15 = 19.29 Subtract 15 from both sides
x = 19.29 - 15
x = 4.29
The Clark family went out to dinner. If their dinner bill came to $81.50 and they wish to leave a 18% tip, how much should they tip?
Answer: The correct answer is B.
Step-by-step explanation:
We are given the cost of restaurant meal of M. Clark is $25.50.
and she has given 20% of the meal's cost as a tip to the waiter.
Step 1: Calculating the amount of tip paid
Total tip paid = $5.1
Step 2: To find the total amount, we add the cost of the meal and the tip paid
Total amount = Cost of the meal + Tip paid
Total amount = $25.50 + $5.10
Total amount paid by Ms. Clark = $30.6

4/2n+5/3c=1
Solve for c.
-Multiply both sides by (blank) to clear fractions.
Answer:
We conclude that:
[tex]c=-\frac{5n}{3\left(-n+2\right)};\quad \:n\ne \:2[/tex]
Step-by-step explanation:
Given the expression
[tex]\frac{4}{2n}+\frac{5}{3c}=1[/tex]
Let us solve for 'c'
[tex]\frac{4}{2n}+\frac{5}{3c}=1[/tex]
Least Common Multiplier of 2n, 3c: 6nc
Now multiply both sides by LCM = 6nc
[tex]\frac{4}{2n}\cdot \:6nc+\frac{5}{3c}\cdot \:6nc=1\cdot \:6nc[/tex]
Simplify
[tex]12c+10n=6nc[/tex]
Subtract 10n from both sides
[tex]12c+10n-10n=6nc-10n[/tex]
Simplify
[tex]12c=6nc-10n[/tex]
Subtract 6nc from both sides
[tex]12c-6nc=6nc-10n-6nc[/tex]
Simplify
[tex]12c-6nc=-10n[/tex]
Factor 12c - 6nc = 6c(2-n)
[tex]6c\left(2-n\right)=-10n[/tex]
Divide both sides by 6(2-n); n≠2
[tex]\frac{6c\left(2-n\right)}{6\left(2-n\right)}=\frac{-10n}{6\left(2-n\right)};\quad \:n\ne \:2[/tex]
simplify
[tex]c=-\frac{5n}{3\left(-n+2\right)};\quad \:n\ne \:2[/tex]
Therefore, we conclude that:
[tex]c=-\frac{5n}{3\left(-n+2\right)};\quad \:n\ne \:2[/tex]

At a restaurant last night, 8 people ordered salads, 10 ordered steaks, 18 ordered chicken, and 14 ordered pasta.
From this information, how many people out of 100 would you expect to order chicken?
Answer:
36 people would order chicken.
Step-by-step explanation:
Case I: (50 People in Total)
Total Number of People Ordering=8+10+18+14=50
Percentage of People ordering chicken=people ordering chicken/total number of people=18/50=0.36%
Case II: (100 People in Total)
Number of People ordering chicken=percentage of people ordering chicken x total number of people=0.36 x 100=36
A rectangle has a perimeter of 23 cm. Its area is 33 cm2. Determine the
dimensions of the rectangle. You must show all work to earn full marks. No work
shown & a correct answer will earn a mark of zero.
Answer:
length = 6 cm; width = 5.5 cm
Step-by-step explanation:
Let the length = x. Let the width = y.
We use the formulas for area and perimeter using x and y, and the given values.
area = length * width
perimeter = 2(length + width)
xy = 33
2(x + y) = 23
Solve the first equation for x:
x = 33/y
Substitute 33/y for x in the second equation.
2(33/y + y) = 23
66/y + 2y = 23
Mulrtiply both sides by y.
66 + 2y^2 = 23y
2y^2 - 23y + 66 = 0
(2y - 11)(y - 6) = 0
2y - 11 = 0 or y - 6 = 0
y = 11/2 = 5.5 or y = 6
xy = 33
x * 11/2 = 33
x = 33 * 2/11
x = 6
Answer: length = 6 cm; width = 5.5 cm
