Answer:

x = 7/2 y = 5/2

Write these numbers from least to greatest -0.615, -5/8, -0.62
inna [77]
Well -5/8 as a decimal would be -0.625.
So, the order would be -0.615 -0.62(0) and then -5/8 (or -0.625).
You could easily search up 5/8 as a decimal :)

Type the dimensions of a different shaped box that has the same volume
defon

Step-by-step explanation:

120ft³ = 3ft × 4ft × 10ft

120ft³ = 1ft × 1ft × 120ft

120ft³ = 2ft × 2ft × 30ft

120ft³ = 5ft × 3ft × 8ft

...

Taking fractions or mixed numbers as dimensions, you can give infinitely many such shapes with a volume of 120ft³.

4X + 8 &lt; 1 + ( 2X - 5) PLEASE EXPLAIN
Simora [160]

Answer:

x < - 6

Step-by-step explanation:

Given

4x + 8 < 1 +(2x - 5) ← remove parenthesis

4x + 8 < 1 + 2x - 5, that is

4x + 8 < 2x - 4 ( subtract 2x from both sides )

2x + 8 < - 4 ( subtract 8 from both sides )

2x < - 12 ( divide both sides by 2 )

x < - 6
