If you are taking the cm to km then it would be like this
4.5km*4.1cm= 18.45km
Answer:
The width is .16 miles and the length is .3 miles
Step-by-step explanation:
Use the area formula for a rectangle and the fact that the length = .14 + w. Your formula will look like this then:
.048 = w(.14 + w)
Distribute through the parenthesis to get
Get everything on one side of the equals sign and set the whole equal to 0:
Let's multiply everything by 1000 to get rid of those decimals:
Now we need to factor that to solve for w:
w = .16 and w = -.3
Since the two things in math that will never ever be negative are distance measures and time, we can safely disregard the -.3. That means that the width is .16 and the length is ,16 + .14 which is .3. There you go!
Answer:
t=9
Step-by-step explanation:
Solve -
Distribute :7-(5t - 13) = - 25
7 - 5t + 13 = - 25
Add the numbers :7 – 57 + 13 = -25
20-51 = -25
Rearrange terms :20-51 = -25
-51+ 20 = -25
Subtract 20 from both sides :-51 + 20 = -25
-51+20-20-25-20
Simplify :Subtract the numbers
-51+ 20-20-25-20
-5:=-25-20
Subtract the numbers
-51 = -25-20
-51 = -45
-51 = -45
Divide both sides by the same factor : -51 = -45 -5t -5 -45- -5 =
Simplify : Cancel terms that are in both the numerator and denominator :: -5t - = -45 - -5
t = - 45 - -5
Divide the numbers :
t = - 45 - -5 ” t=9 ” here’s the answer
