Answer:
The expression is (80w+300)
Step-by-step explanation:
Let
y ----> the total amount of money in both accounts
s ----> the amount of money in saving account
c ----> the amount of money in checking account
w ----> the number of weeks
we know that
saving account
s=50w+200 -----> equation A
checking account
c=30w+100 ----> equation B
To find out the total amount of money in both accounts, sum equation A and equation B
y=s+c
substitute
y=(50w+200)+(30w+100)
y=(50w+30w)+(200+100)
y=80w+300
therefore
The expression is (80w+300)
Answer:
$1.6
Step-by-step explanation:
We need to find the cost of 80 cm of copper pipe at $2 a metre.
Cost of 1 metre = $2
80 cm = 0.8 m
It means,
0.8 m = $2 × 0.8
= $1.6
So, the cost of 80 cm of copper pipe is equal to $1.6.
Answer:
Yes!
Step-by-step explanation:
In Pythagorean Triples, the two legs always have to add up to be a greater number than the hypotenuse. In this case, 12 and 16 are the legs and 20 is the hypotenuse. The sum of 12 and 16 is 28. That is more than 20, so 12, 16 and 20 make a right triangle. I hope this helps you!
