User: what is a fine-grained rock?

Weegy: rhyolite has fine grains of quartz and feldspar. Usually these grains are too small to be visible to the naked eye other answerers said granite. [ they are incorrect. Granite is a course grained rock containing quartz and feldspar ]


User: then what are coarse-grained rock

Weegy: Intrusive igneous rocks are formed from magma that cools and solidifies within the crust of a planet, surrounded by pre-existing rock (called country rock), the magma cools slowly, and as a result these rocks are coarse grained. [ ]

–3(x – 5) – 8(y + 2) + (–3)(6 – 4b)
=-3x+15-8(y+2)-3(6-4b)
=-3x+15-(8y+16)-3(6-4b)
=-3-8y-1-3(6-4b)
=-3x-8y-1-3(-4b+6)
=-3x-8y-1+12b-18
=12b-3x-8y-19
