Answer:
A) 3.5
16 shovels full
Step-by-step explanation:
9x + 13 = 17x - 15
8x = 28
x = 3.5
20 + 5x = 32 + 4.25x
0.75x = 12
x = 16
4 parts of water is to 1 part of glue
Then 1 part of water is to 1/4 parts of glue.
21×20÷14
=3×20÷2
=3×10
x=30
=1
(-2-√3)(-2+√3)
=-2(-2+√3)-√3(-2+√3)
=4-2√3+2√3-√9
=4-3
