3. The cost of a taxi ride is the sum of a fixed cost of $2,50 for the first kilometer, plus
$175 for each additional kilometer,
a. White an equation that relates the cost of the taxi ride, Fdollars, to the distance
travelled,
Determine the cost of a 28km taxi ride. Show all the math!
Answer:
y=2.50+175*(x-1)
$4727.50
Step-by-step explanation:
y=2.50+175*(x-1)
The first km costs 2.50 which is why you add it. You do x-1 because the 175 is charged for each additional km. So, if you traveled one km it would cost 2.50.
y=2.5+175*(28-1)
y=2.5+175*27
y=2.5+4725
y=$4727.50
alvin is 11 years older than ella. the sun of their ages is 59. what is elgas age
Answer:
Hii, okay so the answer 48
Step-by-step explanation:
Just subtract, Hope this helps :)
Answer:
24 years old
Step-by-step explanation:
Given information:
• Alvin is 11 years older than Ella.
• The sum of Alvin and Ella's ages is 59.
First, put the given information into an equation that can solve for Ella's age:
x = Ella's age
x + 11 = Alvin's age
x + x + 11 = 59 Combine like terms.
2x + 11 = 59 Subtract both sides of the equation by 11 to isolate x.
2x = 48 Divide both sides by 2 to get the value of x.
x = 24
Ella's age is 24 years old.

100 yd. =
Answer:
1 yard = 3 feet
We can re-write this by dividing both sides by yards or feet to get
1 = 3 feet / 1 yard
or
1 yard / 3 feet = 1
Since we're solving for feet we want yards to cancel, so use the top proportion
(3 feet / 1 yard)(100 yards) = 300 feet / 1 = 300 feet

Mr. See got $1675 from selling 50 thumb drives and computer keyboards. Each thumb drives cost $24 and each computer keyboard cost $49. How many computer keyboards did he sell?
Answer:
19 keyboards
Step-by-step explanation:
Let d = thumb drives; and k = computer keyboards
Total number of sales of thumb drives and keyboards is 50
50 = d + k
Rearranged:
d = 50 - k
Total revenue from the sale of $24 thumb drives and $49 keyboards is $1675
1675 = 24d + 49k
Sub in d = 50 - k
1675 = 24(50 - k) + 49k
1675 = 1200 - 24k + 49k
475 = 25k
k = 475/25
k = 19
(To check, d = 50 - 19 = 31)
Y+2=-(x+4) in slope intercept form
Answer:
y=-x-6
Step-by-step explanation:
First, you have to distribute the - that is outside the parentheses. That leaves you with -x-4. So now your equation is y+2=-x-4. You want the y by itself so you subtract two from both sides leaving you with y=-x-4-2, which adds up to y=-x-6.
The sum of the speeds two trains is 717.6 miles per hour. If the speed of the first train is 6.4 mph faster than that of the second train, find the speeds
of each.
What is the speed of the first train?
Train 1 = x + 6.4
Train 2 = x
(x) + (x + 6.4) = 717.6
2x + 6.4 = 717.6
2x = 711.2
x = 355.6
Train 1 = 355.6 + 6.4 = 362 mph
Train 2 = 355.6 mph
Hope this helps!! :)

2. Aimee lives 4/5 of a mile from
the park. She has walked 2/3 of
the way to the park. How far has
Aimee walked?
Answer:
[tex]\frac{8}{15}[/tex] of a mile
Step-by-step explanation:
To find a segment of a fraction, you must first find the LCM of each value's denominator:
LCM - Lowest Common Multiple
The lowest common multiple is the number that shows up first in each number's multiple set.
Example: LCM of 4 and 6
Multiples of 4: 4, 8, 12, 16, 20
Multiples of 6: 6, 12, 18, 24, 30
Because 12 is the first number to show up in each multiple set, 12 is the LCM.
So, to be able to solve this problem easy, do the same with 5 and 3:
5, 10, 15, 20, 25
3, 6, 9, 12, 15
Since 15 is the first number in both sets, 15 is the LCM.
The next step is to multiply [tex]\frac{4}{5}[/tex] by [tex]\frac{x}{x}[/tex], x being the value that can be multiplied with the denominator to equal 15:
[tex]\frac{4}{5}[/tex] × [tex]\frac{3}{3}[/tex] = [tex]\frac{12}{15}[/tex]
To find how much [tex]\frac{2}{3}[/tex] of [tex]\frac{12}{15}[/tex] is, multiply the fractions together:
[tex]\frac{12}{15}[/tex] × [tex]\frac{2}{3}[/tex] = [tex]\frac{24}{45}[/tex]
Simplify the fraction by dividing the numerator and denominator by 3.
[tex]\frac{24}{45}[/tex] ÷ [tex]\frac{3}{3}[/tex] = [tex]\frac{8}{15}[/tex]
Because the fraction can't be simplified any further, Aimee has walked a total of [tex]\frac{8}{15}[/tex] of a mile.
Please help maths question which box is it and why!
Answer:
the third one because it will make more sense
Step-by-step explanation:
the number of girls in the class was 1 less than 3 times the number of boys there were 15 students in all. How many were boys, and how many were girls
There was 4 boys and 11 girls in the class.
Let x represent the number of boys and y represent the number of girls.
Since the number of girls in the class was 1 less than 3 times the number of boys, hence:
y = 3x - 1
3x - y = 1 (1)
Also, there were 15 students in all, hence:
x + y = 15 (2)
Solving equations 1 and 2 simultaneously gives:
x = 4, y = 11
Hence, there was 4 boys and 11 girls in the class.

Commutative property of multipcation 3x4=12
Answer:
3x4=12 is the same as
4x3=12 and
12/3=4 and
12/4=3
The commutative property of multiplication is true for the expression 4 x 3 = 3 x 4 = 12.
What is multiplication?Multiplication is one of four mathematical arithmetic operations.
It is also a process of adding the same types of expression for some number of times.
The repeated addition is multiplication.
Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.
The commutative property of multiplication:
Let a and b are the two numbers.
And the product of a x b is n.
So, a x b = b x a = n
Changing the numbers position does not affect the result.
Here,
3 x 4 = 4 x 3
12 = 12
This expression holds the commutative property of multiplication.
Therefore, 3 x 4 = 12 holds the commutative property.

Additional comment
Both the numerator and denominator are polynomial functions. A polynomial function is odd if it contains only odd-degree terms, like the function in the numerator. A polynomial function is even if it contains only even-degree terms, like the function in the denominator. (A constant is 0 degree--even.)
A rational function consisting of the ratio of odd or even functions (not "neither"), will be odd or even according to the parity of the ratio:
odd/odd = even/even = even function
odd/even = even/odd = odd function . . . . . the situation in this problem
