At its maximum speed, a motorboat can travel 10 miles downstream on a river in 20 minutes. It takes 30 minutes for the boat to travel back upstream the same 10 miles, also at maximum speed.
Write a system of two equations that could be used to find the maximum speed of the motorboat in still water. Let b represent the maximum speed of the motorboat in miles per hour and let r represent the speed of the river's current in miles per hour. Convert the times into hours. Solve the system of equations for b and r to determine the boat's maximum speed in still water and the speed of the river's current.
ASAP Please answer Part B Question 2.
Answer:
6
Step-by-step explanation:
Divide 18 by the total number of parts in the ratio (1+2=3)
Since the ratio of stores to other buildings is 1 to 2, 6 is your answer, as it is a third of 18.
How can you determine the sale price if you are given the regular price and the percent of markdown
Answer:

Jackie needs to save $125 to go to a concert. He has saved $35. He makes $7.50 an hour at his job.
Let x representing the number of hours.
Which equation and solution can be used to show how many hours jackie must work in order to have enough money to go to the concert?
A. 125x + 35 = 750; x = 5.75
B. 35 - 7.5x = 125; x = 6
C. 7.5x + 35 = 125; x = 12
D. 35x + 125 = 750; x = 18
Answer:
C
Step-by-step
Answer:
Answer is C
Step-by-step explanation:
First Jackie needs to save $125
y = 125
He already saved $35, this is our constant
He makes $7.50 an hour on his job,
Our variable x is hours
125 = 7.50x + 35
If we solve for x, we get x = 12

What is the value of 2y- 6 if y = 12
Answer:19
Step-by-step explanation:
The answer is 19 because you need to do 12*2 and then subtract 6. 24-6=19
Answer:
18
Step-by-step explanation:
1.) 2y -6
2 ) 2(12) - 6
3.) 24 - 6
Answer ~ 18
1.) 12 equals y so put 12 in place of y
2.) Using PEMDAS, multiply 12 × 2 which equals 24.
3.) Then you subtract 6 from 24 which equals 18.
(NOT MATH ITS SCIENCE HELP PLEASE)If a builder wanted to construct a shopping mall on a barrier island, which of the following questions would be the most significant concern for him to consider?
A.
Where would be the best place to build the mall so that it is protected from the impact of storms which causes the winds and waves to constantly redistribute the sand?
B.
Before construction begins, should large amounts of sand be removed from the
island first in order to prevent erosion of the beach?
C.
Since the islands are constantly changing, what location would offer the best access to sand resources to aid in maintaining the island?
D.
If an earthquake were to occur, would the islands sink below sea level, causing a tsunami to crash on the mainland
Answer:
Option A
Step-by-step explanation:
The graph models the linear relationship between the temperature of Earth's atmosphere and the altitude above sea level. Earth's Atmosphere Which of these best represents the rate of change of the temperature with respect to altitude? -6.5°C/km -3.5°C/km -0.29°C/km -0.15°C/km
Answer:
A. -6.5°C/km
Step-by-step explanation:
It's easier to find slope if we can locate two points.
Looking at the graph, it looks like it passes through the points (4, -10) and (7,-30).
To find the slope, we divide the difference of the y-coordinates by the difference of the x-coordinates. Here, the difference in the y-coordinates is:
-10 - (-30) = -10 + 30 = 20
The difference in the x-coordinates is:
4 - 7 = -3
So, the slope is:
20/(-3) = -20/3 ≈ -6.67
This is the closest to the first answer choice, -6.5°C/km, so that is the answer.

Solve for x: -243 = -9(10 + x)
I will reward Brainliest
Answer:
x = 17
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define Equation
-243 = -9(10 + x)
Step 2: Solve for x
Divide -9 on both sides: 27 = 10 + xIsolate x: 17 = xRewrite: x = 17Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: -243 = -9(10 + 17)Add: -243 = -9(27)Multiply: -243 = -243Here we see that -243 does indeed equal -243.
∴ x = 17 is the solution to the equation.

Write the phrase "9 increased by a number x" as an algebraic expression
Answer:
9+x
Step-by-step explanation:
To write 9 increased by a number x, you need to know that when it says "increased by" it means adding.
So it is saying 9 is being added by x, or 9+x as an algebraic expression.
The phrase "9 increased by a number x" as an algebraic expression would be; 9+x
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
We need to write the given phrase "9 increased by a number x" as an algebraic expression
Let the unknown number = x
To write 9 increased by a number x, we need to know that when it says "increased by" it means adding.
