Answer:

a=29

Step-by-step explanation:

5a-100=45

Add 100 to both sides

Divide both sides by 5

a=29

Answer: a = 29

Step-by-step explanation:

5a - 100 = 45

To find the value of a, put a the subject of the equation

5a = 45 + 100

5a= 145

Divide both sides by 5

a = 145/5

a = 29

Check:

5 (29) - 100= 45

145 - 100 = 45

I hope this is clear, please mark as brainliest answer.

(1/3)9 to the third power =
AlekseyPX
The answer would be 
1/3 * 9 = 3,
3^3 = 3*3*3, which then we multiply:
3*3=9, 9*3=27.
27 is the answer.


Hope this helps and have a nice day:)

In a pen of goats and chickens, there are 40 heads and 150 feet. How many goats and chickens are in the pen?
s2008m [1.1K]

Hey there!!

A chicken has 1 head and 2 feet . A goat has 1 head and 4 feet

For heads, total = 40

Let us take the number of chickens as ' x ' and goats as ' y '

x + y = 40 ------------- ( 1 )

2x + 4y = 150 ----------- ( 2 )

Multiply the first equation with 2

2x + 2y = 80

2x + 4y = 150

Subtract the first equation from the first

2y = 70

y = 35

Number of goats = 35

substitute this in other equation

x + y = 40

x + 35 = 40

x = 5

Number of chickens are 4

Hope it helps!
