How to find the unit rate of 14lb for $2.99

Answers

Okay so let's try to find the amount of money needed to buy 1 lb. Therefore, let's divide the fraction by 14. 
(14)/(2.99) 
Then we'll divide both the numerator and denominator by 14. 
(14)/(2.99) ÷ (14)/(14)
Then we simplify and get:
14÷14=1     2.99÷14=.2135   We can round that to .21
The unit rate for each pound would be 1:.21
I don't know if that helped, but yeah. :)


Look at the units.
If you divide (2.99 dollars) by (14 lb), the quotient will be
(dollars per pound),which is exactly what you want.

The value of x in 3(x+5)=12

Answers

Answer:

x = -1

Step-by-step explanation:

3(x+5)=12

Divide each side by 3

3/3(x+5)=12/3

x+5 = 4

Subtract 5 from each side

x+5-5 = 4-5

x = -1

Answer:

x=-1

Step-by-step explanation:

3(x+5)=12

Step 1: Simplify both sides of the equation.

3(x+5)=12

(3)(x)+(3)(5)=12(Distribute)

3x+15=12

Step 2: Subtract 15 from both sides.

3x+15−15=12−15

3x=−3

Step 3: Divide both sides by 3.

3x

3

−3

x=−1

A square garden has a diagonal of 34 ft. Colton wants to put a fence around the entire garden. How much fencing will he need? Round to the nearest foot.

ok
pythagorean theorem
a and b are legs, c is hypotonuse (diagonal in this problem)
in square, legs are equal
a=b

a^2+b^2=c^2

diagonal is 34
a=b
a^2+a^2=34^2
2a^2=1156
divide both sides by 2
a^2=578
a=17√2

perimiter is 4 time 1 side for square

Let s be the length of a side. 

By the Pythagorean Theorem (or knowledge of 45-45-90 triangles) we can find the length of a side from the hypotenuse. 
s² + s² = 34² 
2s² = 34² 
2s² = 1156 
s² = 578 

s = √578 
s ≈ 24.04 

There are 4 sides to the square: 
P = 4s 
P ≈ 96.16 

Answer: 
About 96 feet
