Answer:
305
Step-by-step explanation:
If she is at day 19, that means you have to multiply 15 (phones repaired each day) times 19 (19th day) in order to get how many phones she has counted which is 285. To find how much she has left, you have to subtract 285 from 590 which gets you 305.
Select the correct answer. Which statement is true about this equation? -9(x + 3) + 12 = -3(2x + 5) − 3x A. The equation has one solution, x = 1. B. The equation has one solution, x = 0. C. The equation has no solution. D. The equation has infinitely many solutions.
Answer:
its D
Step-by-step explanation:
-9(x + 3) + 12 = -3(2x + 5) − 3x
-9x-27+25 = -6x-15-3x
-9x-15 = -9x - 15
same on both sides
so x has infinitely many solutions
The equation has no solutions. Option C is correct.
To figure out which statement is true for equation -9(x + 3) + 12 = -3(2x + 5) − 3x.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
-9(x + 3) + 12 = -3(2x + 5) − 3x.
Simplification,
LHS
= -9(x + 3) + 12
= -9x -21 + 12
= -9x -9
RHS,
= -3(2x + 5) − 3x
= -6x - 15 - 3x
= -9x - 15
Equation RHS and LHS,
-9x - 15 = -9x -9
-15 = -9
Implies, the value of x terminate means the given expression has no solution,
Thus, the equation has no solutions. Option C is correct.

Jack can long-jump 195% of his height with a running start. If Jack is 50 inches tall, how far can he long-jump?
Jack can jump upto 97.5 inches.
What is Equation Modelling?
Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have Jack who can long-jump 195% of his height with a running start.
Assume that he can jump a height of [x] inches. So -
x = 195% of 50
x = (195/100) x 50
x = 97.5 inches
Therefore, Jack can jump upto 97.5 inches.

Which of the following is a valid conclusion based on the given argument?
If 2x + 3 = 13, then x = 5.
Answer:
Given that x=5, when we substitute in 5 for 2x + 3 = 13, the equation will turn out to be true.
Step-by-step explanation:
2x + 3 = 13 x=5
2(5)+3=13
10+3=13
13=13
2x + 3 = 13
x=5
2(5)+3=13
10+3=13
13=13
Hey, I don´t understand the graphing part of inequalities.
Answer:
See explaination
Step-by-step explanation:
While graphing inequalities, think of the inequality sign as an equal sign.
So, y=mx+b.
Say the inequality was y>3x+7, I would think fo the > as an equal sign.
So, in your head, "write" it like this: y=3x+7. Hope this helps.

The balance of a loan is $2,570 in January, and the monthly payment is $125.50. The relationship between the loan balance, y, and the number of monthly payments made since January, x, can be represented by the equation y = 2,570 - 125.50x. In what months does the loan balance, y, meet the condition, $1,600 < y < $2,000? January February March April May June July August September October November December
Answer:
600<2570-125.5x<2000 subtract 2570 from all terms...
-970<-125.5x<-570 divide all terms by -125.5 (and reverse signs because of division by a negative!)
7.73>x>4.54 and x is months since January, and since months can only be integers...
x=[5,7]
So January + 5, 6, and 7 respectively are the three months that satisfy the equation...
June, July, and August.

Find the surface area of a sphere with a radius of ²√² feet.
Answer:
Step-by-step explanation:
Remark
I'm going to take a guess that you mean
√2 for the radius.
Givens
r = √2
Area = 4 * pi * r^2
Solution
Area = 4 * 3.14 * (√2)^2
Area = 4 * 3.14 * 2
Area = 25.12 feet^2

6. If m∠COD=8x+13, m∠BOC=3x-10, and m∠BOD=12x-6, find m∠BOD
Answer:
Step-by-step explanation:
Given
m∠COD=8x+13,
m∠BOC=3x-10, and
m∠BOD=12x-6
The following addition property is true;
<BOD = <BOC + <COD
Substitute
12x-6 = 3x-10+8x+13
12x-6 = 11x+3
12x-11x = 3+6
x = 9
Get <BOD
<BOD = 12x-6
<BOD = 12(9)-6
<BOD = 108-6
<BOD = 102°

Area of circle = 200.96 units²
Step-by-step explanation:
The formula to find the area of a circle is: πr², where r is the radius (which is half of the diameter)
So the diameter is 16 and of 16 is 8, which is the radius.
Sub it into the formula of a circle and you would get the area of a circle.
3.14 x 8²
Use calculator
Area of circle = 200.96 units²

A group of ‘n' friends decided to rent a condominium for a one week vacation in Florida. They decided to share the weekly rent of ‘m' dollars equally. If due to an unanticipated reason two members of the group couldn't make the trip, and the rest of the friends decided not to charge the two who pulled out for the rent; what will be the additional amount each of the remaining friends must pay for renting the condominium?
Answer:
2m / n² - 2n
Step-by-step explanation:
Given that:
Number of friends = n
Weekly rent = $m
To share rent fee equally :
Each friend will pay : $m / n
If 2 of the friend couldn't make the trip:
Additional amount to be shared by the others = 2(m/n) = 2m/n
Hence additional fee per friend who eventually made the trip:
Additional amount to be shared / number of friend who eventually made the trip
= (2m/n) ÷ (n - 2)
= 2m / n * 1 / n - 2
= 2m / n(n-2)
= 2m / n² - 2n
