Answer:
-1
Step-by-step explanation:
The solution to the expression using the values a = 5 and b = 1 is - 1
The equation given :
12 + [2 - (4 × a²)] ÷ 7 + bThe given values of a and b are ; 5 and 1 respectively
Substitute the values of a and b into the equation 12 + [2 - (4 × 5²)] ÷ 7 + 1Using BODMAS :
solve the expression in the bracket first :
12 + [2 - 100] ÷ 7 + 112 + [-98] ÷ 7 + 1Solve the division next :
12 - 14 + 1Solve the addition next :
12 - 13-1Therefore, the solution of the expression with the given values of a and b is - 1

Kiley and her parents traveled to visit her grandmother. They drove 24.3 miles from their house to the airport in hour. At the airport, they exited the car and walked for hour to the waiting area by the gate to board their plane. Their walk covered 1.2 miles. From the waiting area, they walked another 0.1 mile to board the plane. The plane left the gate 45 minutes after they arrived at the waiting area. The plane flew 346 miles in hours. After the plane landed, Kiley and her parents walked for 30 minutes, covering 1.1 miles, before they found a cab. It was a 15-minute cab ride to get to Kiley’s grandmother’s house, which was 12.3 miles away.
Answer the following questions about kileys trip. All questions are written in terms of an average rate. Assume that an average rate includes the time that kiley is at rest.
In this task you will write the ratio of miles to hours for each leg of kileys trip. You will then express the ratio as a decimal number. Next you will find the unit rate in miles per hour for each leg of the trip.

66.5/x = 17/8.5
*Side note, the / are fractions
Answer:
33.25
Step-by-step explanation:
To solve this equation we need to solve for X.
66.5/x = 17/8.5
(Handle the division on the right side first.)
66.5/x = 2
(Move the x to the right side of the equation)
66.5 = 2x
(Divide both sides by 2 to get rid of the 2)
33.25 = x

5. 1
Step-by-step explanation:
1. because 4/3 is the same as 1 & 1/3, they are the same because if you take the 4 and make it a 3, it is 1 whole, and then you put 1/3 at the end, because the is still a left over 1/3. 2. I know this because 2/3 is bigger than 1/3, and 4/3 is equal to 1 & 1/3.

Solve the following
Logan has two aquariums. One aquarium contains 1.3 cubic feet of water and the other contains 1.9 cubic feet of water. The water in the larger aquarium weighs 37.44 pounds more than the water in the smaller aquarium. Write an equation with a variable on both sides to represent the situation. Then find the weight of 1 cubic foot of water.
Answer:
62.4
Step-by-step explanation:
1. 1.3x+37.44=1.9x
2. 1.3x+37.44-1.3x=1.9x-1.3x
0.6x=37.44
3. x=37.44/0.6=62.4
