Step-by-step explanation:
2.50x+3.00y=?
x=8 y=11
Answer:
- 4 ≤ x < 2
Step-by-step explanation:
The interval is [ - 4, 2 )
The bracket on the left side indicates x can equal - 4
The parenthesis on the right side indicates x cannot equal 2
Thus the inequality represented by the graph is
- 4 ≤ x < 2
Answer:
Will you do somemthing for me
Step-by-step explanation:
Answer:
- x^2+y
- 3(n-7)
- 37x-9.85
Step-by-step explanation:
1. If x represents a number, then x^2 represents its square. If y represents a second number, then the sum of that square and the second number is ...
x^2 + y
__
2. The difference of a number (n) and 7 is (n-7). Three times that difference is ...
3(n - 7)
__
3. If x represents a number, then the product of 37 and a number is 37x. 9.85 less than that is ...
37x - 9.85
Answer:
Step-by-step explanation:
Find the area of each shape, then multiply by 20, then round to nearest hundred.
Half circle:
=πr²/2
=50π
=157.08
Large square:
=L•w
=20(22)
=440
Small square:
=L(w)
=12(3)
=36
Triangle:
=b(h)/2
=8(3)/2
=12
Btu req:
=(157.08+440+36+12)(20)
=(645.08)(20)
=12901.6
=12900 BTU
