Solve: -25 < x + 20 < 25

Mathematics
1 answer:
denis23 [38]2 years ago
8 0

Answer:

-45 < x < 5 (see graph below)

Step-by-step explanation:

to isolate x by itself, subtract 20 from all three terms of the equation:

(-25-20)

once you finish subtracting 20, x should be by itself, making the equation graphable:

-45 < x < 5

since x is not equal to -45 or 25, the graph line endings have open circles.

21. Jim loves nuts. He plans to spend at most $24 to buy cashews and peanuts for after work
FinnZ [79.3K]

He can buy 5 of the $3 nut and 1 of the $5 nuts.

5x3=15

5x1=5

15+5=20 and that’s less than 24.

So Jim can use $20 to buy the $3 one 5 times and the $5 one 1 time.

lesantik [10]

Answer:

not a right triangle

Step-by-step explanation:

We can use the Pythagorean theorem to see if it is a right triangle

a^2 + b^2 = c^2

15^2 + 12^2 = 21^2

225 + 144 = 441

369 = 441

This is not true so it is not a right triangle
