Roberto decided to get rid of all his baseball cards, so he gave his four friends 32 baseball cards each. how many baseball cards did he have before he giving them to his friends? a. write an algebraic equation that represents the scenario. b. solve to find the solution.

Step-by-step explanation:

y = number of cards Roberto had in total

x = number of friends he is giving to the cards to

(a)

y = 32x

(b)

To find the number of cards he had in total, just plugin the number of friends he gave his cards to, which was 4 friends

y = 32x

y = 32(4)

y = 128

Roberto had 128 cards

answer: what equations are there

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.
