A baker needs between 40 lb and 50 lb of a flour-sugar mixture that contains ten times as much flour as sugar. What are the possible weights of flour the baker can use?

Step-by-step explanation:

Let x=amount of sugar needed

Then 10x=amount of flour needed

Now we can set up an inequality:

40<= 11x <=50 divide each term by 11

40/11<=x<=50/11 now multiply each term by 10x (amount of sugar needed)

400/11 <= 10x <=500/11 or

36.36 <=10x <= 45.45

The possible weights of flour the baker can use is greater than or equal to 36.36 lb and less than or equal to 45.45 lb

your answer would be b

step-by-step explanation:

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
