Answer:
A: y = 9.5x + 22.5
Step-by-step explanation:
For the entirety of this problem, p will represent a pair of pants and b will represent a bracelet.
Step 1) Set up equations for Destiny and Guadalupe
Destiny: 178 = 2p + 6b
Guadalupe: 155 = 3p + 2b
I will be using substitution to solve this problem, but elimination can also be used.
Step 2) Solve Destiny's equation for p
178 = 2p + 6b
178 - 6b = 2p
89 - 3b = p
Step 3) Substitute the found value of p from Destiny's equation into Guadalupe's equation and solve for b
155 = 3(89 - 3b) + 2b
155 = 267 - 9b + 2b
155 = 267 - 7b
-7b = -112
b = 16
Step 4) Use the value of b found in step 3, plug that back into our equation from step 2 and solve for p
89 - 3(16) = p
89 - 48 = p
p = 41
one pair of pants = $16
one bracelet = $41
Hope this helps!! :)
In 60 minutes, the machine can sew 300 buttons. The machine sews 5 buttons a minute. 60 x 5 = 300
Answer:
Irrational
Step-by-step explanation:
A rational number and an irrational number when added will given another irrational number only.
Example consider a rational number 2 and an irrational number √3.
When we add these two we get
2+√3. an irrational number only
There is no chance of getting a rational number when a non zero rational and irrational is added. In other words, there is nothing to cancel the irrational part when another rational number is added.
Hence the result would be irrational
Thus answer is irrational.
