Remark
I take it MO is bisected by N. If it isn't we need some clue how to proceed.
Step One
Solve for x
9x = 2(x + 7) remove the brackets.
9x = 2x + 14 Subtract 2x from both sides.
9x - 2x = 14
7x = 14 Divide by 7
x = 14/7
x = 2
Step Two
Find MO
2(x + 7) + 9x = MO
2(2 + 7) + 9(2) = MO
2*9 + 9*2 = MO
18 + 18 = MO
36 = MO <<<<< Answer
Answer:
Y = A/X
Step-by-step explanation:
divide x from xy, balance the equation by dividing x from a.
From the given, we have 232 90Th. Thorium has 90 protons in its nucleus, the number of neutrons is calculated by subtracting 90 from 232 which gives an answer of 142. Then, for the second given 228 88Ra, Radium has 88 protons and the number of its neutrons is calculated by subtracting 88 from 228 which is equal to 140.
The final equation that would give us the proper nuclear decay reaction,
232 90Th --> 228 88Ra + 4 2a
where 4 2a is an alpha particle.
Answer:
40 square feet
Step-by-step explanation:
You want the area in square feet of a closet that is 10 feet long and 48 inches wide.
<h3>Area</h3>
The area is the product of the length and width. For area to be in square feet, both dimensions must be in feet.
12 in = 1 ft
48 in = 4 ft
Then the area is ...
A = LW = (10 ft)(4 ft) = 40 ft²
The area of the closet is 40 square feet.
