Jonathan forgot his math homework on the kitchen table and left for school without it. He biked at the speed of 15 mph. His mother saw the homework when he was already 1 mile from home, and started chasing him. She drove at a speed of 25 mph and caught him at the school entrance. How far is the school from Jonathan's home?
Answer:
2.5 miles
Step-by-step explanation:
We know that: time = distance/speed
Now, if the distance of the school from Jonathan's home is y.
At speed of 15 mph, Jonathans time is; time = y/15 hours
At 25 mph, his mother's time was;
time = y/25 hours
We are told that Jonathan was 1 mile from home when he saw his mother.
Thus means that difference in time is;
Time difference = 1/15 hours
Thus;
y/15 hours - y/25 hours = 1/15 hours
Multiply through by 75 to get;
5y - 3y = 5
2y = 5
y = 5/2
y = 2.5 miles

Answer:
x=4
Step-by-step explanation:
1) first write it down --> 11x-2+9x+1=19x+3
2) then combine like terms on the left side of the equation. --> 20x-1=19x+3
3) Then subract 19x on both sides --> x-1=3
4) After add 1 to both sides --> x=4

Which fractions are equivalent to 3/5 Check all that apply.
Answer:
12/20 21/35 30/50
Step-by-step explanation:
These are all equivalent fractions to 3/5.
Hope this helps!
The fractions that are equivalent to 3/5 are C) 12/20, D) 21/35, and E) 30/50.
To determine which fractions are equivalent to 3/5, we need to find fractions that can be simplified to the same value.
The fraction 3/5 cannot be simplified further because 3 and 5 have no common factors other than 1.
Let's check each option:
A) 8/10 can be simplified to 4/5, which is not equivalent to 3/5.
B) 8/15 cannot be simplified further, but it is not equal to 3/5.
C) 12/20 can be simplified to 3/5, which is equivalent to 3/5.
D) 21/35 can be simplified to 3/5, which is equivalent to 3/5.
E) 30/50 can be simplified to 3/5, which is equivalent to 3/5.
Therefore, the fractions that are equivalent to 3/5 are C) 12/20, D) 21/35, and E) 30/50.

If the surface area of a cylinder is 800 in^2 and the height is 15 in, what is the base?
Answer:
base = diameter
Step-by-step explanation:
if the surface area of the cylinder is 800...
the height is 15... then the formula must be 3.14 x 15 x R2
r squared is supposed to be the square of the radius of the cylinder\
conclusion: 3.14 x 15 x R2 is 800_
so.multiply then..find the radius and add the answer you get to find the diameter ..Solve for x: 13x + 12] = 18

AM = 5x - 2 and MB = 2x + 19, Find the length of AB
Answer:
The answer would be: -0.01
Step-by-step explanation:
1) State what is given
AM = 5x -2 and MB = 2x +19
2) Make an equation that can satisfy the problem
AM + BM = AB
This is the equation, because if I am to put this on a line,
A M B
-_____________-_____________-
You can see that is you combine the lengths AM and BM you can find the total length of AB.
A M + M B
-_____________- + -_____________-
(M point is actually one point, but I am trying to show that if the line were to be cut in half, then put back together you get you full length, which is AB)
3) Substitute
(5x - 2) + (2x + 19) = AB
4) Now Solve!
5x - 2 + 2x + 19 = AB
(Rearrange to combine like terms)
5x + 2x + 19 - 2 = AB
7x + 17 = AB
(That is your equation to find AB! But they want the specific length)
So...
We solve it!
7x = -17
(By moving the 17 to the other side of the = sign, it becomes negative)
7x = -17
7 7
(Dividing both sides by 7 in order to get x alone)
x = -2.43
(I rounded to the hundredths place)
Now substitute that into x into you original equation)
5(-2.43) - 2 + 2(-2.43) + 19 = AB
-12.15 - 2 - 4.86 + 19 = AB
-14.15 - 4.86 + 19
-19.01 + 19 = -0.01
= -0.01
(I believe this would be the answer, but it doesn't seem to fit right, so please understand, that if this is wrong, I AM SO SORRY ;-;)
(I tried my best on this problem, but I bet it isn't the answer, so if I get this wrong tell me so that I can remove it! :)
A board 60 in long is cut into two parts so that the longer piece is 5 times the shorter. What are the two lengths of the two pieces ?
The shorter piece is _____ a° in
the longer piece is _____a° in
Answer:
Longer piece: 50 in
Shorter piece: 10 in
Step-by-step explanation:
Lets make the shorter piece = x
Leta make the longer piece = 5x
Since the longer piece is 5 times the shorter, this is why we put 5x, because 5 times the shorter. We also have to find the two lengths of the pieces which in total equals 60 in.
x + 5x = 60 in
If we substitute the x to 10:
10 + 50 = 60 in
10 in = shorter length
50 in = longer length
What is 6 1/2 doubled?
Answer:
13
Step-by-step explanation:
6 1/2 x 6 1/2
or
6.5 + 6.5 =13
6+6=12
0.5 + 0.5=1
12+1=13
the double of 6 1/2 is 26/2, which simplifies to 13
To find the double of 6 1/2, we first convert the mixed number 6 1/2 to an improper fraction. We multiply the whole number (6) by the denominator (2), which gives us 12. Then, we add the numerator (1) to get 13. So, 6 1/2 as an improper fraction is 13/2.
To double this fraction, we multiply the numerator (13) by 2, resulting in 26. The denominator remains the same (2). Therefore, the double of 6 1/2 is 26/2, which simplifies to 13. In other words, doubling 6 1/2 gives us the whole number 13.

What is the solution to the system of equations graphed below
Y=2x-7 y=-x-1
The value of the common solution to the system of equation is (2,-3).
What is System of Equation?The system of equation is set of equations which have a common solution.
The figure shows the graph of two equations, these equations are a straight line function and the common solution is represented by a point in the image.
The solution of the system of equation can be obtained both by solving using substitution method and even by plotting the graph and finding the intersection point.
The system of equation is,
y = 2x - 7
y = -x -1
The value of y from equation 2 will be substituted in equation 1
-x -1 = 2x -7
3x = 6
x = 2

Two supplementary angles. One angle is 25 more than the second angle, find the measure of the second angle. The measure of the second angle is
Answer:
77.5°
Step-by-step explanation:
Let s represent the measure of the second angle. Then the first angle is s+25. These two angles are supplementary, so their sum is 180:
(s+25) +s = 180
2s = 155
s = 77.5
The measure of the second angle is 77.5°.
