Hello, I know this isn’t a homework question but I am not able to skip this activity right here and I can’t seem to find out why . The guy speaking kept saying “Use the tool to help solve the linear system of equations” but I can’t seem to understand what tool . Is this some sort of glitch?

This is more of a computer kind of thing, but try clicking the next thing at the bottom.

Step-by-step explanation:

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
