Step-by-step explanation:
So the test he scored lowest is 69 so discard this score and put x for it
average=numbers added together then summ is divided by number of numbers exg
average of 2 and 4 and 5 is 2+4+5=11 then 3 numbers so 11/3 is average or aprox 3 and 2/3 so
=average
he wants his new average to be at least 82 so
solve
treat as equation
first add like terms in top
multiply both sides by 5 to clear fraction
325+x
410
subtract 325 from both sides
x
85
he must get
85 to get an average of at least 82
1. 86/2=43/new price of one shirt
2. 43-15=28/original price of one shirt

Answer:
360 miles
Step-by-step explanation:
Every half inch on the map equal 45 miles on the highway. Find out how many half-inches there are in 4 inches, and multiply that by 45 to get the answer.
To do this, first divide 4 by 0.5
4/0.5 = 4/(1/2) = 4(2/1) = 8
There 8 half-inches in 4 inches
**Also think that there are 2 halves in 1, so in 4 there are 2(4) halves, which is 8
Now take 8 and multiply by 45
8(45) = 360
The highway is 360 miles long
