lara [203]2 years ago
3 0

Step-by-step explanation:

x = BD

\frac{ab}{ad}  =  \frac{bc}{de} \\  \frac{10}{10 + bd}   =  \frac{12}{21}  \\ 12 \times (10 + bd) = 21 \times 10 \\ 120 + 12bd = 210 \\ 12bd = 210 - 120 \\ 12bd = 90 \\ bd =  \frac{90}{12} \\ bd = 7.5 \\

Which situation can be modeled by the inequality 60−15x≥7?
Pepsi [2]

Answer:

D

Step-by-step explanation:

To find a situation for 60−15x≥7, look for a story where 60 is a constant value that is decreasing by 15 for a number of times and where equal to or at least 7 is an option.

A. x would be weeks and it would decrease by 7x. This is not it.

B. 15 songs packages would have x be the number of packages not the price. This is not it.

C. This doesn't work either because if you want to owe them less than 7 it would have the sign < not >.

D. You have 60 to spend and you decrease it by $15 for each hat you buy till you save $7. This is it.
