If it costs 650 per kg then 500g will cost half of that as 500g is half of a kg so the answer is 650/2 = 325
Answer:
y = -7/8x - 3/2
Step-by-step explanation:
If you look at the point where x = 0, you can see that y = -3/2.
That is the y-intercept. In the equation y = mx + b, b is the y-intercept. In this case, b = -3/2
The first choice is the only equation that ends with -3/2, so that is the answer.
Answer:
yes it
Step-by-step explanation:
1/2y=1
y=1 x 2 (because e do to multiply the one by 2/1 to get y alone)
y=2 ( if y is always equal to two there is no variation meaning it is linear)
Answer:
Step-by-step explanation:
Fist you add -13 to 6y and than 4x that should be 69420
Given:
Two electrons are added to each of six atoms in a group.
To find:
The expression for the net change in charge.
Solution:
Charge of atoms = Number protons - Number of electrons.
Let number of atoms be x.
6 atoms = 2 electrons added
1 atom = electrons added
1 atom = electrons added
x atoms = electrons added
Therefore, the net change in charge is represented by the expression because we subtract number of electrons to find atom charge, where, x is the number of atoms.
6 atoms = 2 protons removed
1 atom = protons removed
1 atom = protons removed
x atoms = protons removed
Therefore, the net change in charge is represented by the expression , where, x is the number of atoms.
