A cyclist rode 3.75 miles in 0.3 hours.
How fast was she going in miles per hour?
At that rate, how long will it take her to go 4.5 miles?
Answer:
A. 12.5 miles per hour B. 0.36 hours
Step-by-step explanation:
3.75/.30=12.5 , so divide 3.75 by the time 0.30 hours and you get your miles per hour
next, take 4.5 and divide by the new mph 12.5 from your previous answer.
4.5/12.5=0.36 hours
Answer:
1.) 12.5 miles per hour 2.) 0.36 hours
hope it helped! <33 .
Step-by-step explanation:
1. Factor x²+5x-24
2. Factor 2n²-5n-3
Given problems;
1. Factor; x²+5x-24
To factor this equation, we must understand that this is a quadratic equation.
A quadratic equation usually has two roots.
Equate to zero;x²+5x-24 = 0
Then find two numbers whose product is -24 and their sum is +5the numbers are +8 and -3
then replace 5x with the number;
x² + 8x - 3x - 24 = 0
Now factorize;
x(x +8) - 3(x + 8) = 0
(x-3)(x+8) = 0
Factoring gives (x-3)(x+8)
2. Factor 2n² - 5n -3;
Equate to zero;
2n² - 5n -3 = 0
Find the number whose sum is -5 and the product gives -6( 2 x -3);
the number is -6 and +1;
2n² - 6n + n -3 = 0
2n(n-3) + 1(n-3) = 0
(2n + 1)(n-3) = 0
The factor of the equation is (2n + 1)(n-3).

Step-by-step explanation: 1/5 of 75 =15
75 - 15 =60

which of the following is the standard form of 36 / 24
Answer:
15 x 10^-1
Step-by-step explanation:
36÷24=1.5
In this case I'm considering 15 as the base of my standard form.
To make 15 a 1.5, you'll have to move from right to left one unit and on the number line moving from the right to left gives you a negative number of units moved

Answer: 12.5
y = 12.5x
Step-by-step explanation:
k = y/x
= 50/4
= 12.5
Notice that you could have used: 62.5/5 = 12.5 or 75/6 = 12.5
The equation is: y = kx
y = 12.5x
Add:
1. 258 and -453
2. -528 and -243
3. -13 and 15
Subtract:
1. -3 from 12
2. 4 from -7
3. -8 from -2

Answer:
1. -195
2.-771
3. 2
1. 9
2.-3
3. -10
4. 205
Step-by-step explanation:
Answer:
Add:1. 258 and -453
=258 -453
= -195
2.-528 and -243
= -528 + (-243)
= -538 -243
= - (528+243)
= -771
3.-13 and 15
= -13 + 15
= 2
Subtract:1. -3 from 12
= 12 - (-3)
= 12+3
=15
2. 4 from -7
= 4 - (-7)
= 4+7
= -11
3. -8 from -2
= -8 - (-2)
= -8+2
= 6
4.329 from -124
= 329 - (-124)
= 329 + 124
= -453

Hope it helps!1. At Chesterfield Town Center, Alex is at the Barnes and Noble at coordinates (-10,9) and Jeff is at the Macy's which is at (4,-6). They decide to meet for lunch in the food court which is halfway between their locations. What are the coordinates of the food court?
Answer:
(-1,-1)
Step-by-step explanation:
The easiest way I know how to explain it is you put the numbers on a line for instance
-6, -5,-4,-3,-2,-1,0,1,2,3,4
and the number in the very middle of the y then for x
-10,-9,-8,-7,-6,-5,-4,-3,-2,-1,0,1,2,3,4,5,6,7,8,9
and then again you use the midpoint for the x
because they are trying to meet each other half way you are trying to find the midpoint.

Alice chose five positive integers and found that their product was even. What is the maximum number of odd integers she could have chosen?
Answer:
In order for a product to be even, at least one factor must be even (so that the product is divisible by 2). The minimum number of even integers she could have chosen is 1, so the maximum number of odd integers she could have chosen is 4 :)

A
0.625%
B
1.60%
C
55%
D.
62.5%
Answer:
i think it's D. because 55% isn't enough, but very close, and 0.625% is waaaay too little, and the same for 1.60.
Step-by-step explanation:

The percentage of Janet's money does Emma have is D. 62.5%.

Answer:
a = 7.5
Step-by-step explanation:
7*3(2a-1) over 7 = 6.7
(2a-1) = 42/3
2a-1=14
2a=13
a=7.5
I hope this helps you out!
Answer:
put 6 over 1 then look for the LCM of 7 and 1 the LCM is 7 then ask yourself how times does seven go into 7 one time right so multiply 1 by 3(2a - 1) then ask yourself how many times does 1 go into 7 it goes 7 times right multiply 7 by 6 so your equation is like this 3(2a - 1) = 42 open the bracket so it will be 6a - 3 = 42 collect the like terms so 3a = 42+3, 3a =45 , divide both sides by 3 so x =15

Step-by-step explanation:
Answer:
5
Step-by-step explanation:
The area of each square is equal to 1.
We can see that two triangles could form a rectangle with 10 units of area, so it's just divide it.

PLZ HELP MEEEE!!!!!!!!!!!!!!!
Answer:
To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.
Step-by-step explanation:
1) The product of a number and -7 is 63
2) 10 subtracted from a number is 15
3) two-fifths of a number is -12
4) 8% of a number is 20
5) the sum of twice a number and 17 is -1
6) nine less than the product of a number and -4 is 35
Step-by-step explanation:
let the no. be x
for 1,
x× -7 = 63
or, x= 63 ÷ -7
or, x = -9
therefore -9times -7 is 63.
for 2
by question
x -10= 15
or, x = 15+10
or, x = 25
therefore 25 minus 10 equals 15.
for 3
by question
(2/5) of x = -12
or, x = -12×(5/2)
r, x= -6×5
or, x = -30
therefore 2/5 of -30 is -12
for 4
by question,
8%of x = 20
or, 8x/100=20
or, 8x = 20×100
or, x = 2000÷8
or, x= 250
therefore 8% of 250 is 20.
for 5
by question,
2x+17 = -1
or, 2x = -1 -17
or, 2x = -18
or, x = -18 ÷ 2
or, x =-9
therefore -9 times 2 plus 17 equals -1.
for 6 dont know
