Answer:
1/2 lb of pecans would cost $1.9
3 lbs of pecans would cost $11.4
Step-by-step explanation:
The rate given is 5 lb of pecans for $19
FIND THE UNIT RATE OF DOLLARS PER POUND OF PECANS BY:
19 ÷ 5 = 3.8
THE UNIT RATE IS $3.8 per pound of pecans.
Use unit rate to determine how much will the following amounts of pecans cost:
1/2 lbs
1/2 x 3.8 = $1.9
3 lbs
3 x 3.8 = $11.4
Answer:they will drive 500 miles each day.
Step-by-step explanation:
The Thompson family is traveling 1,500 miles to visit relatives. They plan to drive the same distance each day.
Let x represent the distance that they travel each day. If the Thompsons make the trip in 3 days, it means that the total distance that they travelled in 3 days would be
3 × x = 3x miles
Therefore , the distance that they will drive each day would be
3x = 1500
Dividing both sides of the equation by 3, it becomes
3x/3 = 1500/3
x = 500 miles

Answer:
m = 18
Step-by-step explanation:
In an arithmetic progression, the middle term of three is half the sum of the terms on either side.
a1 +a3 = 2(a2)
(m +9) +(2m +7) = 2(2m -1)
3m +16 = 4m -2 . . . . . . collect terms
18 = m . . . . . . . . . . . . . . add 2-3m
