Answer:
$1.80
Step-by-step explanation:
5 ounces
1st ounce = .80¢ plus 25¢ for every other ounce. You have 4 ounces left. 25¢ times 4. = $1.00
$1.00
+0.80

$1.80
Answer:
6.68, 13.37, 14.95
Step-by-step explanation:
One of the legs is twice as long as the other.
b = 2a
The perimeter is 35.
35 = a + b + c
The triangle is a right triangle.
c² = a² + b²
Three equations, three variables. Start by plugging the first equation into the second and solving for c.
35 = a + 2a + c
c = 35 − 3a
Now plug this and the first equation into the Pythagorean theorem:
(35 − 3a)² = a² + (2a)²
1225 − 210a + 9a² = a² + 4a²
1225 − 210a + 4a² = 0
Solve with quadratic formula:
a = [ -(-210) ± √((-210)² − 4(4)(1225)) ] / 2(4)
a = (210 ± √24500) / 8
a ≈ 6.68 or 45.82
Since the perimeter is 35, a = 6.68. Therefore, the other sides are:
b ≈ 13.37
c ≈ 14.95
1/7-9/7n+6/7
1-9/7n
that is the extended form and is simplified
Hope it help! :)

Step-by-step explanation:
From the question, we are informed that the trail that Brandon is hiking is 4.2 miles long, and Brandon plans to stop for Lunch after he completes 1.6 miles.
The expression represents the remaining distance Brandon needs to hike will be gotten by subtracting 1.6 miles from 4.2 miles. This will be:
= 4.2 - 1.6
= 2.6 miles
