When x = 1, both expressions have a value of 18, and when x = 8, both expressions have a value of 60. When x = 2, both expressions have a value of 15, and when x = 6, both expressions have a value of 39. ITS NOT 30 I TOOK THE TEST
Answer:
a) When x = 3, both expressions have a value of 30. When x = 5, both expressions have a value of 42.
b) When x = 1, both expressions have a value of 18, and when x = 8, both expressions have a value of 60.
Step-by-step explanation:
Which best proves why the expressions 4 (x + 3) + 2 x and 6 (x + 2) must be equivalent expressions?
Mathematically this is expressed as:
4(x + 3) + 2x = 6(x + 2)
Verifying the options
a) When x = 3, both expressions have a value of 30. When x = 5, both expressions have a value of 42.
When x = 3
4(x + 3) + 2x = 6(x + 2)
4(3 + 3) + 2(3)= 6(3 + 2)
24 + 6 = 6(5)
30 = 30
When x = 5
4(x + 3) + 2x = 6(x + 2)
4(5 + 3) + 2(5)= 6(5 + 2)
4(8) + 10 = 6(7)
42 = 42
Statement in option a is correct
b) When x = 1, both expressions have a value of 18, and when x = 8, both expressions have a value of 60.
When x = 1
4(1 + 3) + 2x = 6(x + 2)
4(1 + 3) + 2(1)= 6(1 + 2)
4(4) + 2 = 6(3)
18 = 18
When x = 8
4(8 + 3) + 2x = 6(8 + 2)
4(11) + 2(8)= 6(8 + 2)
44 + 16 = 6(10)
60 = 60
Statement in option b is correct
c) When x = 2, both expressions have a value of 15, and when x = 6, both expressions have a value of 39.
When x = 2
4(x + 3) + 2x = 6(x + 2)
4( 2 + 3) + 2(2)= 6(2 + 2)
4(5)+ 4 = 6(4)
20 + 4 = 6(4)
24 = 24
4(x + 3) + 2x = 6(x + 2)
4(6 + 3) + 2(6)= 6(6 + 2)
4(9) + 12 = 6(8)
48 = 48
Statement in Option c is wrong
Hence, Statement in Option a and b is correct

Step-by-step explanation:
Let the unknown number be n
We are to write the expression as equation;
Six times a number plus 4 is the same as the number minus 11.
Six times a number is given as;
6n
Six times a number plus 4 is expressed as 6n+4
The unknown number minus 11 will be expressed as n-11
Finally If Six times a number plus 4 is the same as the number minus 11, them!
6n+4 = n-11
Next is to calculate n;
Collect like terms;
6n-n = -11-4
5n =-15
Divide through by5

Rachel saved money to buy art supplies. She used 13 of her savings to buy brushes. She used 35 of her savings to buy paint. What fraction of her savings does she have remaining?
Given:
Rachel used [tex]\dfrac{1}{3}[/tex] of her savings to buy brushes.
She used [tex]\dfrac{3}{5}[/tex] of her savings to buy paint.
To find:
The fraction for remaining savings.
Solution:
Fraction that Rachel used of her savings to buy brushes and paint is
[tex]\text{Fraction for used amount}=\dfrac{1}{3}+\dfrac{3}{5}[/tex]
[tex]=\dfrac{5+9}{15}[/tex]
[tex]=\dfrac{14}{15}[/tex]
Now,
[tex]\text{Fraction for remaining savings}=1-\text{Fraction for used amount}[/tex]
[tex]\text{Fraction for remaining savings}=1-\dfrac{14}{15}[/tex]
[tex]\text{Fraction for remaining savings}=\dfrac{1}{15}[/tex]
Therefore, [tex]\dfrac{1}{15}[/tex] of her savings is remaining.

Ryan is choosing between two exercise routines. In Routine #1, he burns 22 calories walking. He then runs at a rate that burns 10.5 calories per minute. In Routine #2, he burns 39 calories walking. He then runs at a rate that burns 6.25 calories per minute.
Complete question :
Ryan is choosing between two exercise routines. In Routine #1, he burns 22 calories walking. He then runs at a rate that burns 10.5 calories per minute. In Routine #2, he burns 39 calories walking. He then runs at a rate that burns 6.25 calories per minute. For what amounts of time spent running will Routine #1 burn at most as many calories as Routine #2?
Answer:
4 minutes
Step-by-step explanation:
Given the following exercise routines :
Routine #1,
Walking : burns 22 calories walking. He then running : burns 10.5 calories per minute.
Routine #2,
Walking : burns 39 calories walking. He then running : burns 6.25 calories per minute.
Let number of tone spent running = t
Hence,
Routine 1 ; calories burned
22 + 10.5t
Routine 2 ; calories burned
39 + 6.25t
Equating the two equations :
22 + 10.5t = 39 + 6.25t
10.5t - 6.25t = 39 - 22
4.25t = 17
t = 17/4.25
t = 4

On a piece of paper, graph f(x) = 6× (0.4)^x Then determine which answer choice matches the graph you drew.
One a piece of paper, graph f(x)= (0.4)^x. To determine which answer choice matches the graph you drew.
Answer: Graph B
The graph of a function f(x) = 6(0.4)× is shown in graph (B) because the domain of the function is all real numbers and the range of a function is f(x) > 0, the y-intercept of the function is (0, 6)
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function:
f(x) = 6(0.4)×
The domain of the function is all real numbers.
The range of the function:
f(x) > 0
Plug x = 0
y = 6
Thus, the graph of a function f(x) = 6(0.4)× is shown in graph (B) because the domain of the function is all real numbers and the range of a function is f(x) > 0, the y-intercept of the function is (0, 6)

a $260 suit price is marked down 10 % find the sale price
Answer:
260*0.90=sales price=234
Step-by-step explanation:
Step-by-step explanation: We first need to find the discount.
The formula for discount is shown below.
Original Price × Rate of Discount = Discount
So here, the original price is $260 and the
rate of discount is 10% off which we can write as .10.
So we multiply 260 by .20
260 x .10 gives us 26.
So the discount is $26.
Now let's find the sale price.
The formula for sale price is shown below.
Original Price - Discount = Sale Price
Since the original price is $260 ad the discount is $26,
we have 260 - 26 which gives us 234.
So the sale price of the suit is $234.

The first equation of the system is multiplied by 2. By what number would you multiply the second
equation to eliminate the y variable by adding?
4x – 3y = 6
6x + 2y = 10
Answer:
we will have to multiply the second equation by 3 to eliminate the y variable by adding.
Step-by-step explanation:
Given the equations
4x – 3y = 6 → (1)
6x + 2y = 10 → (2)
As the first equation is multiplied by 2,
2(4x – 3y) = (2)6
8x - 6y = 12 → (3)
As we have to eliminate y,
so multiply the second equation by 3,
6x + 2y = 10
3(6x + 2y) = 3(10)
18x + 6y = 30 → (4)
So now adding the new equations (3) and (4) will eliminate the y variable by adding
8x - 6y = 12
18x + 6y = 30
--------------------
26x + 0y = 42
26x = 42
x = 42/26
x = 21/13
Therefore, we will have to multiply the second equation by 3 to eliminate the y variable by adding.
