9514 1404 393
Answer:
$170
Step-by-step explanation:
If the price of a pair of Jordans is the same as the price of two shirts, the total purchase has a value equivalent to that of 3 Jordans.
pair of Jordans = $510/3 = $170
Answer:
$170

So I had a test in math and I’ve always been cheating and I was the best math student but when the class was gonna end I told the teacher I only have two questions and she told me to still stay and when I finished the submit button didn’t work and the teacher told me to present my screen and I did but when I did the teacher face wasn’t happy because when I showed her my screen in the tabs I had tabs that help me cheat the test. But the teacher didn’t tell me anything and she told me that if I have the notes for all my questions answers and I didn’t know what to say so I said yes! But I told her if I should take pictures of the answers and she said no. And I started panicking so she told me to reload the WHOLE THING so I did and all my 18 questions answers deleted and I told the teacher I had to go to my other class and she said bye. I’m literally crying. I’m hitting my head so hard. Karma is real:( F
Answer: OMG that is sad why did you hide the the cheating tabs
Step-by-step explanation:
Answer:
Girl why did u cheat in the first place???

Is this relation a function
Answer:
You can tell if a relation is a function if each input value only has ONE output value. Examples below

Solve the equation 2(3x + 7) + 5 = 49.
Answer:
x=5
Step-by-step explanation:
Answer:
5
Step-by-step explanation:
A car covers a distance of 600 m in 2 minutes whereas a train covers a distance of 75 km in 50 minutes. Find the ratio of their speed.
answer
1:5
Step-by-step explanation:
To find speed use the formula
speed=distance/time
The car's speed is 600m ÷2mins(120secs)
(600÷120)
5m/s
The trains speed will be
speed=distance/time
=75÷50mins(5/6hrs)
=90km/hr
Ratio of their speed should be
first change the speed of the car 5 m/s to km/hr. 5×18/5 = 18km/hr
the speed of the train is 90km/hr
18:90 simplified it will be 1:5
Just some simple fraction problems, I am stuck on this though.
Answer:
5 1/6 ÷ 4 2/3 = 31/28
3 3/4 ÷ 1 2/8 = 3
4 2/4 ÷ 2 1/4 = 2
5 2/5 ÷ 1 4/5 = 3
4 2/8 ÷ 3 2/4 = 17/4
3 3/9 ÷ 2 4/12 = 10/7
7 1/2 ÷ 3 3/5 = 25/12
6 2/8 ÷ 3 1/3 = 15/8
Explanation:
5 1/6 ÷ 4 2/3 = 31/6 ÷ 14/3 = (31/14) / (6/3) = (31/14) / 2 [when you divide by a certain number you multiply that number by the denominator] = 31/28
5 1/6 ÷ 4 2/3 = 31/6 ÷ 14/3 = 31/6 × 3/14
What is the equation in slope intercept form of the line that passes through the point (2,2) and is perpendicular to the line represented by y=2/5x + 2
Answer:
y=
Step-by-step explanation:
Perpendicular means opposite reciprocal of the slope. This means that the slope would change from 2/5 to 5/2 and add a negative, so it is -5/2.
y=-5/2x+b
2=-5/2 (2) +b
7=b
y=-5/2x+7

What is the rule for reflecting across the x-axis?
Answer:
See below
Step-by-step explanation:
If we want to reflect across x-axis, we'll change the y-coordinate of the co-ordinate to it's opposite (If it's negative, it will become positive and vice versa) while the x-coordinate will remain the same.

~AnonymousHelper1807What’s the equation?
|8|+|-7| its 15 right?
Answer:
Yes. |8|+|-7| = 15
Step-by-step explanation:
the absolute cancels out the -, so it would mean that -7 is now positive 7, so yes it'd be 15

Enter the equation of the line in slope-intercept form.
The line perpendicular to y = −2x that passes through (0, 0).
The equation of the line that passes through (0, 0) is y = .
Answer:
The equation is;
y = x/2
Step-by-step explanation:
General form of the equation of a straight line is;
y = mx + c
where m slope
For the given equation , the slope is -2
If two lines are perpendicular, then the product of their slopes is -1
So the slope of the second line will be
-2 * m2 = -1
m2 = -1/-2
m2 = 1/2
Using the point-slope form, we have
y-y1 = m(x-x1)
Here (x1,y1) = (0,0)
y-0 = 1/2(x-0)
y = 1/2x or simply
y = x/2
