Barbara was asked by her teacher to subtract 2 from a number and to divide the result by 6. However, she subtracted 6 from that number and divided the result by 2 to get
37. If she had done it correctly, what answer would she have gotten?

13

Step-by-step explanation:

To find the right answer, do her work in reverse

37 times 2 = 74

74 + 6 = 80

Barbara had started with the number 80

Now do the work the way the teacher asked her to do it

80 - 2 = 78

78 / 6 = 13

Hope this helps!

the answer would be c:   ax + b = ax + c

step-by-step explanation:

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.

in this lesson, students will use double number lines and ratio reasoning to solve ratio problems. by partitioning double number lines into proportionate intervals, students will build an understanding of equivalent ratio relationships as those that are generated by multiplying or dividing two related quantities by the same number. this lesson will build upon students' prior understanding of multiplicative comparisons, number line reasoning and equivalent fractions (while highlighting the difference between equivalent fractions and equivalent ratios); and will build toward future work in this unit on building ratio tables, and work in future grades in proportionality, scaling, and expressing and graphing linear functions.
