one month, ruby worked 6 hours more than isaac, and svetlana worked 4 times as many hors as ruby. together they worked 114 hours. find the number of hours each person worked
Answer:
Ruby = 18+6=24
Isaac = 18
Svetlana = 4*18=72
24+18+72=114
Step-by-step explanation:
Ruby= x+6
Isaac= x
Svetlana = 4x
x+6+x+4x = 114
6x = 114 - 6
x = 108/6
X = 18

Answer: Amir Is Right
Step-by-step explanation: 4 seconds and it made 8 clicks
4/8 is 2 and the check if its right you can do 2x4 to get the clicks that were made in 4 seconds.
Answer:
Amir is correct.
Step-by-step explanation:
To find the cps (clicks per second), divide the clicks by the number of seconds.
[tex]\frac{8 clicks}{4 seconds}[/tex]
Simplify the fraction.
[tex]\frac{2 clicks}{1 seconds}[/tex]
Since 2 over 1 is really just 2 and the line of the fraction can be read as "per", we could re-write the above fraction in words as:
2 clicks per second
Therefor, Amir is correct.

Cupcakes Promotion All cupcakes at $2 each !
Buy 8 and get 1 free!
How many cupcakes will Fatimah get if she paid $80 during the promotion?
Answer:
45
Step-by-step explanation:
....................
Hey there! I'm happy to help!
We see that the cupcakes are $2, but for every 8 you buy you get 1 free.
So, if we buy 8 cupcakes, we will be paying $16, but we will actually be receiving 9 donuts, so that means that for every $16 we pay, we get 9 donuts.
Let's see how many times $16 goes into $80.
80/16=5
So, this means that our $16 that gives us 9 donuts was done 5 times, which totals up to 80 dollars. Let's multiply our donuts now.
9*5=45
So, Fatimah will get 45 donuts during the promotion.

In a survey 25% of the people said they live in a city of 60 people said they live in a city how many people were surveyed
Step-by-step explanation:
You said:
'25% of the people = 60 people "
' 25% ' means 0.25
'of ' means ' times'
So people (0.25) x (the people) = 60
the people=60/0.25
the people=6000/25
the people=240
Answer:
Step-by-step explanation:
Let the number of people = x
25% of x = 60
[tex]\dfrac{25}{100}*x=60\\\\x=\dfrac{60*100}{25}\\\\x=60*4\\\\x= 240[/tex]

Answer:
C
Step-by-step explanation:
We want to solve the inequality:
[tex]\displaystyle 5.1(3 + 2.2x) > -14.25 - 6(1.7x+4)[/tex]
Distribute:
[tex](15.3+11.22x) > -14.25 + (-10.2x-24)[/tex]
Combine like terms:
[tex]15.3 + 11.22x > -10.2x-38.25[/tex]
We can add 10.2x to both sides:
[tex]15.3 + 21.42x > -38.25[/tex]
Subtract 15.3 from both sides:
[tex]21.42x > -53.55[/tex]
And divide both sides by 21.42. Hence:
[tex]\displaystyle x > -2.5[/tex]
This means all values greater than -2.5. Hence, in interval notation:
[tex](-2.5, \infty)[/tex]

Find an equation of the line L that contains the points (0,0) and (5,3)
Y =
Answer:
y = (3/5)*x
Step-by-step explanation:
First, we can use the slope-intercept form of a line, or y=mx+b
To find the slope, m, we can find
(y₂-y₁)/(x₂-x₁). Denoting (0,0) as (x₁,y₁) and (5,3) as (x₂, y₂) (it is perfectly okay to have (0,0) as (x₂, y₂) and (5,3) as (x₁,y₁) as well), we have
(y₂-y₁)/(x₂-x₁) = (3-0)/(5-0) = 3/5
Therefore, our equation is
y = (3/5)x + b
To solve for b, we can plug any value of (x,y) from the line, e.g. (0,0), and solve from there, resulting in
y = mx + b
0 = (3/5)*0 + b
0 = b
Our equation is therefore
y = (3/5)*x + 0
= (3/5)*x

(3,-2) and (6, 1).
y=x-5
y = 5x + 1
y = -x + 5
Answer:
It is y = x - 5
Step-by-step explanation:
General equation of a line:
[tex]{ \bf{y = mx + c}}[/tex]
m is the gradient, and c is y-intercept.
For gradient:
[tex]slope = \frac{y_{2} - y_{1} }{x _{2} - x_{1}} [/tex]
substitute:
[tex]slope = \frac{1 - ( - 2)}{6 - 3} \\ \\ = \frac{3}{3} \\ slope \: = 1[/tex]
m = 1
for y-intercept:
consider point (6, 1):
[tex]y = mx + c \\ 1 = (6 \times 1) + c \\ 1 = 6 + c \\ c = 1 - 6 = - 5[/tex]
therefore:

The senior classes at High School A and High School B planned separate trips to the state fair. The senior class at High School A rented and filled 13 vans and 6 buses with 278 students. High School B rented and filled 10 vans and 12 buses with 428 students. Every van had the same number of students in it as did the buses. Find the number of students in each van and in each bus.
Answer:
8 students in van, 29 students in bus
Step-by-step explanation:
To find the number of students in each van and bus, we can use system of equations to solve. Our first step is to create one equation for High School A and B. Let's use x for vans and y for buses, but ultimately, the variables don't matter that much.
High School A: 13x+6y=278
High School B: 10x+12y=428
Let's use elimination method to solve. We would multiply the first equation by 2.
26x+12y=556
10x+12y=428
Now that the 12y is the same in both equations, let's eliminate y by subtracting the 2 equations.
26x+12y=556
-(10x+12y=428)
16x=128
With 16x=128 left, we can just solve for x.
16x=128 [divide both sides by 16]
x=8
Now that we have x=8, we can plug that into the equations above to find y.
13(8)+6y=278 [multiply]
104+6y=278 [subtract both sides by 104]
6y=174 [divide both sides by 6]
y=29
With x=8 and y=29, we know that there are 8 students in each van and 29 students in each bus.
Step-by-step explanation:
Let,
No. of students in vans = x
No. of students in bus = y
In case 1
13x + 6y = 278(1)
In case 2
10x + 12y = 428(2)
On multiplying eq. 1 by 2
2(13x + 6y) = 2(278)
26x + 12y = 556 (3)
On subtracting 2 and 3
26x + 12y - (10x + 12y) = 556 - 428
26x + 12y - 10x - 12y = 128
16x = 128
x = 128/16
x = 8
From 1
13(8) + 6y = 278
104 + 6y = 278
6y = 278 - 104
6y = 174
y = 174/6
y = 29
