Select all the stories that can be represented by the diagram. Diego spends $1 on 7 Stickers and 3 marbles
Elena spends 57 on 3 notebooks and a $1 pen.
Noah shares 7 grapes with 3 friends. He eats 1 and gives each friend the same number of grapes.
Andre studies 7 hours this week for end-of-year exams. He spends 1 hour on English and an equal number of hours each on math, science, and history.
Lin spends $3 on 7 markers and a $1 pen

Choice C and Choice D

Explanation:

[] Noah shares 7 grapes with 3 friends. He eats 1 and gives each friend the same number of grapes.

[] Andre studies 7 hours this week for end-of-year exams. He spends 1 hour on English and an equal number of hours each on math, science, and history.

Reasoning:

[✗] The first story, with Diego, does not work because the whole is $1 in the problem and $7 in the diagram.

[✗] The second story, with Elena, does not work because the 7 is ignored entirely and the x becomes a known value, 57.

[✓] The third story, with Noah, does work because he splits seven grapes equally among three friends (the x's) and eats one.

[✓] The fourth story, with Andre, does work because 7 hours were spent studying. One on English and the rest (three subjects) split evenly (x).

[✗] The fifth story, with Lin, does not work because the total is $3 when it should be 7.

what are you trying find out?

step-by-step explanation:

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130
