So to get the answer, we just add the number of bones in your hands and bones in your skull
1/4 (bones in hands) + 1/10 (bones in skull)
we can only add fractions that have the same denominator (bottom number in a fraction) so we change the numbers to have a common denominator:
5/20 + 2/20 = 7/20
so 7/20 of your bones are in your hands or skull

Answer:
Choice D
Step-by-step explanation:
(9.1 x 10^5) - (9.3 x 10^4)
910000 - 93000 = 817,000 = 8.17 x 10^5
usually, you would want <u>a whole number</u> in standard notation
A. 0.817 x 10^6 = 817,000
B. 817 x 10^3 = 817,000
C. 8.17 x 10^4 = 81,700
D. 8.17 x 10^5 = 817,000

for this question, it ask you to draw out.
j + 6 ≥ 7
j ≥ 7 - 6
j ≥ 1
How to draw it: 
1. draw a Solid point on the number"1".
2. draw a small vertical line on the top of the point.
3. draw a long horizontal line to number "1" 's right side, and add an arrow in the end of the line.
