d=vt will represent the Motion of Both persons
for Karen
d=59t
for Ricardo
d=65t
They're both 279miles away from each other
Meaning
Dk + Dr = 279
59t + 65t = 279
124t=279
t=279/124
t= 2.25hrs.
You can change to seconds if thats how the answer waa presented.
Convert the following fraction to a decimal.
A. 0.79
B. 0.70
C. 0.7
D. 0.07
Answer:
what is the fraction?
Step-by-step explanation:
Which of the following transformations does not
preserve congruence?
F. (x,y) → (-x, -Y)
G. (x, y) = (-y, -x)
H. (x, y) = (x + 9.y + 9)
J. (x,y) → (9x, 9y)
Answer:
(9x, 9y) dilation
Step-by-step explanation:
(9, 9y) is the answer because F is 180 degrees rotations, G is not real, H is translations, and J is dilations and dilations is multiplying which makes the transformation non congruent.

According to a survey of workers, 5/25 of them walk to work, 1/25 bike, 4/25 carpool, and 15/25 drive alone. What percent of workers walk or bike to work?
Answer: 24%
Step-by-step explanation:
First add up the proportion of people who walk to work and those who bike as well. This will show the proportion of people who walk or bike to work.
This is:
= 5/25 + 1/25
= 6/25
Then convert this to a percentage:
= 6/25 * 100
= 24%
A store offers a discount of 40%. The discount price of a shirt is $42 . What is the regular price?
Answer:
$70 is the regular price of the shirt.
Step-by-step explanation:
One way in which to find the regular price here is to write the equation
0.60s = $42. A 40% discount is reflected in 100% - 40%, or 1.00 - 0.40, which comes out to 0.60.
If 0.60s = $42, then the regular price of the shirt is
s = ($42)/0.60 = $70
Answer:
$70.00
Step-by-step explanation:
use the percent off calculator on freeonlinecalculatoruse.com
hope this helps :)
Nevaeh went shopping for a new phone because of a discount sale. She multiplied the price of the phone by 0.95 to find the price she would actually have to pay, before tax. What percent discount is the sale?
Answer:
95% off
Step-by-step explanation:
because the percent u times by the actual price is the percent u have off
What is the solution to the system of equation of 2x+3y=6 and x-3y=9
Answer:
x = 5
y = -4/3
Step-by-step explanation:
Solve by elimination by adding the two equations together:
2x + 3y = 6
x - 3y = 9
3y and -3y will cancel out. Then, solve for x:
3x = 15
x = 5
Plug in 5 as x into one of the equations, then solve for x:
x - 3y = 9
5 - 3y = 9
-3y = 4
y = -4/3
So, the answer is x = 5 and y = -4/3
ILL MARK BRAINIEST IF YOU CAN DO THIS RIGHT!!! Sorry that it’s sideways that’s the only way it would fit.
state the angle pair relationship then find the value of x
Answer:
x = 11
Step-by-step explanation:
The given angles are corresponding angles and are congruent, then
12x - 9 = 10x + 13 ( subtract 10x from both sides )
2x - 9 = 13 ( add 9 to both sides )
2x = 22 ( divide both sides by 2 )
x = 11
I need help!!!!!!!!!!!!!!!!!
Answer:
1. 4 2. 2 3. Does not exist 4. Does not exist 5. 3
Step-by-step explanation:
1. This is the limit as x approaches 2 from the left. That means that x "sneaks up" on 2, but from the left (ironically moving right). As x does that, the graph rises, heading for 4 (even though the point is "empty"). The limit is 4. See attached image 1
2. Let x sneak up on 2 from the right (so moving left towards 2). As x does that, the graph falls, heading for the y-value 2. The limit is 2. See image 2.
3. This limit (two-sided) does not exist because the one-sided limits had different values.
4. This limit does not exist, either. The limit as x approaches 0 from the left is 4. The limit as x approaches 0 from the right is 0. These are different, so the two-sided limit is not defined.
5. g(2) = 3, where the solid dot is. It's the value of the function at x=2.

What is the perimeter of the shape
Answer:
10 units
Step-by-step explanation:
I can faintly make out the grids in the image, but every line segment per grid is 1 unit, count them up and you get a total of 10 of them. Since I don't know what unit you need them in, they are set as 10 units.
Which of the following functions is equivalent to the function below?
Select three that apply.
f(x)=(13)2x
g(x)=(23)−x
g(x)=9−x
g(x)=3x2
g(x)=(16)x
g(x)=(19)x
g(x)=3−2x
Answer:
g(x) = 3x2
g(x) = 16x
g(x) = 19x
Explanation:
Assuming that you're referring to f(x) = (13)2x, without much context, I'm going to assume that any of the ax + b, are going to be wrong. The the process of elimination, the only ones left are just x and a coefficient.
Hope that helps!

Answer:
I think it's 45 degrees
Step-by-step explanation:
<c is 90 degrees and the interior of every triangle is 180 degrees so then we subtract 90 from 180 which is 90 so we divide 90 by two since b and a seem to be equal which is 45 degrees.

Answer:
x=52
Step-by-step explanation:
vertical angles are congruent so that means the angle measures are the same
so, you can set up this equation:
156=3x
and solve as follows:
156=3x
/3 /3
52=x
To prove that x=52 you can input 52 as x in the equation
156=3(52)
156=156

y = -2x + 3
in the equation y = mx + b, the m represents the slope and b represents the y-intercept
remember that slope is rise over run:
starting from the point (1, 1) you rise 2 up and go over left 1 to reach the second point shown (0, 3).
add a negative sign to show the negative downward slope, and the m in the equation would be -2
the y-intercept is just where the line hits the y-axis, or when the x in the ordered pair is 0. In this graph, one of the points given is (0, 3) so 3 is the y intercept
just plug all that into y = mx + b
m, the slope, is -2 and b, the y- intercept, is 3.
y = -2x + 3 is your answer
