Evaluate the expression 3b-ac when a=2,b=3 and c= -1.5

12
-5
-15.5
24

When a=2, b=3, and c= -1.5, the expression 3b-ac evaluates to:

3(3) - 2(-1.5)
9 + 3
12

Therefore, the expression evaluates to 12.

A consultant charges $30 for each hour she works on a consultation plus a flat 45 dollar consulting fee which equation could be used to find how many hours of work are included in a $210 bill for a consultation

75h=210
45h+30=210
30h+45=210
45h-30=210

The correct equation that could be used to find how many hours of work are included in a $210 bill for a consultation is:

45h + 30 = 210

During your class field trip the teacher plans at a local restaurant and has up to 180 to spend which inequality describes the most number of combo A meals she can purchase for 9.99 each

9.99x≤180
8.99x≥180
8.99x≤180
9.99x≥180

The inequality that describes the most number of combo A meals the teacher can purchase for $9.99 each, given that she has up to $180 to spend, is:

9.99x ≤ 180

Joanne drives a tour bus in Hollywood that can hold up to 10 passengers she charges each passengers 15 dollars to ride what is a reasonable range for this scenario

{0,1,2,3,4,5,6,7,8,9,10}
{0,15,30,45,60,75,90,105,120,135,150}
0≤x≤10
{1,15,2,30,3,45,4,60,5,75,6,90}

A reasonable range for this scenario would be:

0 ≤ x ≤ 10

This range represents the number of passengers (x) that can ride the bus, which can range from 0 to 10 passengers.

Are you sure

Yes, I am sure. A reasonable range for the scenario would be 0 ≤ x ≤ 10, as it represents the number of passengers (x) that can ride on the bus, which can range from 0 to 10 passengers.
