The answer is <span>A.0.5 moles
</span><span>a mole of sodium chloride weighs approximately 58 grams: 1 M - 58 g
</span><span>you have 29 grams of sodium chloride, how many moles of sodium chloride do you have: xM - 29g
1 M : 58g = x : 29 g
x = 1 M : 58g * 29 g = 0.5 M</span>
Answer:
(5, -2)
Step-by-step explanation:
x - 7 = -2x + 8
add 2x to both sides
x - 7 + 2x = -2x + 8 + 2x
3x - 7 = 8
Add 7 to both sides
3x - 7 + 7 = 8 + 7
3x = 15
3x = 15
x = 5
y = 5 - 7
y = -2
Solution (5, -2)
Answer:
x=6
Step-by-step explanation:
Answer:
2/6
Step-by-step explanation:
There are 6 numbers on a regular die, and only 2 numbers that are greater than four that you could get, so the probability of getting a number greater then 4 would be 2/6
Well, 20% is equivalent to (1/5). So, you'd put 50 in the numerator and 5 in the denominator. (50/5) is equal to 10. Then you'd take that value and subtract it from your original value. [ 50 - 10 = 40 ]. 40 Students were at school that day.
