3b) 6/7 you divide by 2
3c) 2/7 you divide by 9
3d) 2/5 you divide by 9
4a) 6
4b) 1 <u>1/4</u> or 5/4 (both are correct)
4c) 3 <u>1/2</u> or 3 <u>3/6</u> (both are correct)
4d) 5 <u>1/8</u>
The fraction bar tells you to divide the top number by the bottom number.
Step-by-step explanation:
For 3a through 3d, you just use the fraction that has a missing number, and if the missing number is at the bottom, use the top number and devide it by the other top number that the fraection is equal to.
For 4a through 4b, devide the top the bottom number
Answer:
Slope = 40
Step-by-step explanation:
Time spent = 70 hours(given)
Fixed charge = $75 (given)
x = Total number of hours (given)
Variable charge = $40 * Total number of hours.
Variable charge = $40x
Fee charged, y = Variable charge + Fixed charge
y = 40x + 75 ($)
The equation of a straight line is given as: y = mx + c
where m = slope
Comparing it with the equation above, m = 40
an adult has 4.94 x 10^13 cells = 49,400,000,000,000
49,400,000,000,000 - 26,000,000,000 = 49,374,000,000,000
scientific notation form : 4.9374 x 10^13
