So here we need to use the formula: Distance = Rate * Time
So for Kate, 5 = r10, so rate = 1/2
Saying that Josh travels at the same speed, means he's traveling at the same rate
So for Josh, 2 = 1/2t, so time = 4 minutes
4 minutes
Answer:
x = 4
Step-by-step explanation:
3x - 10 = 2 | Given
3x = 12 | Add 10 to both sides to isolate 3x
x = 4 | Divide both sides by 3 to get the value of x
Answer:
The combined average is 94%
Step-by-step explanation:
for first period, number of students =40
average =96%
for second period, no of students =20
average =90%
but 
let 
=sum of students for the first period
=sum of students for the second period
for first period;
for second period,
therefore the combined average = 
that is 
so combined average is 94%
Shee needs 448 ounces of lemonade.
448 ÷ 80 =5.8
⇒ There are 5.6 80-ounce of lemonade.
80 ounces of lemonade needed 8 lemons.
448 ounces of lemonade needed 8 x 5.6 = 44.8 lemons.
Tanisha has 38 lemons.
She does not have enough lemons.
She needs 44.8 - 38 = 7 more lemons.
Answer: <span>Tanisha needs more lemons. She needs 7 more.</span>
Answer:
x = 7, x = -3
Step-by-step explanation:
(x - 2)^2 = 25
Take the square root of each side
sqrt((x - 2)^2) =±sqrt( 25)
x-2 = ±5
Add 2 to each side
x-2+2 = 2±5
x = 2±5
x = 2+5, x=2-5
x = 7, x = -3
