The perimeter of a rectangular garden is 24. If the length is half the width, what is<br> the width?

Anna11 [10]

Let length be x

Width be 2x

ATQ

$\\ \sf\longmapsto 2(L+B)=24$

$\\ \sf\longmapsto 2(x+2x)=2=$

$\\ \sf\longmapsto 2(3x)=24$

$\\ \sf\longmapsto 6x=24$

$\\ \sf\longmapsto x=\dfrac{24}{6}$

$\\ \sf\longmapsto x=4$

Find the annual interest rate. Round your answer to the nearest hundredth of a percent. I=$160.67, P=$2000, t=8 months

FinnZ [79.3K]

Let would be the annual interest rate such that,
I = P x r^t
For the 1st
160.67 = (2000) x r*8/12 ; r = 0.02277
The second case is just the same.

Solve for b. 4b-3b+7= 10

Morgarella [4.7K]

b = 3

Step-by-step explanation:

$4b - 3b + 7 = 10$

Add similar terms :

$4b - 3b = b \\ b + 7 = 10$

Collect like terms and simplify

$b = 10 - 7 \\ b = 3$
