-7y -3y +2 = -8y-8
-10y +2 = -8y-8
-10y +8y = -8 -2
-2y = -10
2y = 10
y = 10/2 = 5
Answer:
y = -5/6
Step-by-step explanation:
7y - 3y + 2 = -8y - 8
12y + 2 = -8
12y = -10
y = -10/12 = -5/6
a histogram can be a pie chart but there is no question here
Start by proving to them that the number 0.57 can be converted into a fraction . A whole number can't exactly be put in to a fraction. 0.57 can be converted to 14.25/25. This information means that 0.57 IS a rational number. Hope this convinced them!
Answer:
94% lung capacity.
Step-by-step explanation:
Find the unit rate. Divide 2 by 4 which gets 0.5.
Take 0.5 times 12 (12 months in one year)
You should get 6.
Then, 100 minus 6 (because the patient loses capacity) therefore you should get 94.
Answer:
94.1%
Step-by-step explanation:
Convert that 100% to "1." Then:
Lung capacity as a decimal fraction) = C(x) = 1(1.00-0.02)^x, where x represents the number of 4-month periods.
After the first 4-month period, the lung cap should be 1(1.00-0.02)^1, or 0.98.
After the 2nd 4-month period, 1(0.98)^2, and
After the 3rd 4-month period, 1(0.98)^3, or 0.941
After 1 year (which is after three 4-month periods), the patient's lung cap has declined to 0.941 of its former maximum value (1), or 100%. 0.94 is equivalent to 94.1%.
