Can someone explain how to do this with the answer 20 !
item 3
on your family trip, you used 16 gallons of gas.
if the odometer readings before and after your trip were 112,352 and 112,773, respectively, how many miles per gallon did you average?
round your answer to the nearest whole number.
52
34
27
26

Step-by-step explanation:

First of all we need to know how odometer works. The change in odometer means the distance you have travelled.

Therefore:

112773-112352

=421 miles

Average, meaning you take the distance travelled divided by the gallons of gas used.

421/16

=26.3125

round up

≈26

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.

step-by-step explanation:

1. practice, practice & more practice

2. review errors

3. master the key concepts

do not try to memorise the processes.

4. understand your doubts.

5. create a distraction free study environment

6. create a mathematical dictionary

7. apply maths to real world problems.
