Answer: 1 ) 20.58 cm^3
2 ) $0.09
3 ) $ 0.41
Step-by-step explanation:
Lets x and y are the value of two numbers.
x + y = 16
x - y = 2.4
If x + y = 16 then x = 16 - y
Substitute x = 16 - y into x - y = 2.4
16 - y - y = 2.4
16 - 2y = 2.4
2y = 13.6
y = 6.8
x = 16 - y
x = 16 - 6.8
x = 9.2
Answer:
The value of two numbers are 9.2 and 6.8
Answer:
The only option (0,0) is possible.
Step-by-step explanation:
Here in options four ordered pairs are given and they are (-3,-18), (-0.5,-3), (0,0) and (0.5,3).
Here, the x-values represent the number of books and the y-value represents the total weight of the books, in ounces.
Now, x must be 0 or a positive integer as it is the number of books.
Hence, the only option (0,0) is possible which means that the weight of zero books is zero. (Answer)
Answer:
Step-by-step explanation:
eq. of line parallel to AB is y=2x+a
if it passes through (3,-2) then
-2=2×3+a
a=-2-6=-8
y=2x-8
