If x + 15 = 30, what is the value of 2(x – 5)?
PLEASE ANSWER TODAY!!!
Answer:
Answer is 20
Step-by-step explanation:
X+15=30
30-15= 15 so that means 15+15=30
2(x-5) X is 15 so 15-5=10 then multiply by 2.
The required value of 2(x – 5) is 20 when the equation is x + 15 = 30.
What is an equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
The equation is given in the question, as follows
x + 15 = 30
First, we can solve for x by subtracting 15 from both sides of the equation:
x + 15 - 15 = 30 - 15
x = 15
Next, we can substitute this value of x into 2(x – 5):
2(x – 5) = 2(15 – 5)
2(x – 5) = 2(10)
2(x – 5) = 20
Therefore, the value of 2(x – 5) is 20.

37=d-17
54=d
d=54
Answer:
d=44

22+15=37 so ?-17=37 well its 44 because 44-17=37
im new can anyone help
Answer:
We have the equation:
[tex]W = W_0*(\frac{1}{2})^{0.36*t}[/tex]
Where:
W₀ is the initial area of the wound, and t is the time in days.
Now, if we initially have a wound of 25 mm^2, then:
W₀ = 25mm^2
And we can replace it in the equation, then we get:
[tex]W = (25mm^2)*(\frac{1}{2})^{0.36*t}[/tex]
We want to know the size of this wound after:
a) 1 day.
We know that t represents time in days, so here we just need to replace t by one, then:
[tex]W = (25mm^2)*(\frac{1}{2})^{0.36*1} = 19.5 mm^2[/tex]
b) 1 week
Again, t represents the time in days, so we need to write this in days.
We know that:
1 week = 7 days.
then t = 7
The size of the wound after 7 days is:
[tex]W = (25mm^2)*(\frac{1}{2})^{0.36*7} = 4.36 mm^2[/tex]
9. What is the sales tax on an item that costs $67.00 if the state sales tax is 6.5%?
A. $435
B. $4.35
C. $3.35
D. $.45
Answer:
B
Step-by-step explanation:
Answer:
B. $4.35
Step-by-step explanation:
to find your sales tax you just have to do [cost of the item] x [ percentage as a decimal]= sales tax
so in your case it would be [$67.00] x [0.065] = $4.35

The Variance is defined as the average of the squared differences from the mean.The mean is:
x = (4 + 6 + 7 + 10)/4 = 6.75The variance is:
σ² = [(4 - 6,75)² + (6 - 6.75)² + (7 - 6.75)² + (10 - 6.75)²]/4 = 4.6875PLEASE HELP
The graph shows two lines, A and B.
A graph is shown with x- and y-axes labeled from 0 to 6 at increments of 1. A straight line labeled A joins the ordered pair 2, 6 with the ordered pair 6, 2. Another straight line labeled B joins the ordered pair 0, 3 with the ordered pair 4.5, 6.
Part A: How many solutions does the pair of equations for lines A and B have? Explain your answer.
Part B: What is the solution to the equations of lines A and B? Explain your answer
Answer:
C(2, 2) is the solution to both lines A and B.
Step-by-step explanation:
Line A is given as:
A straight line labeled A joins the ordered pair 3, 0 and the ordered pair 0, 6.
We know that the equation of a line passing through (a,b) and (c,d) is calculated as:
Hence, the equation of line is:
Hence, equation of line A is:
Similarly B is a line passing through (0,0) and (5,5).
Hence, the equation of line B is:
So, from the graph we observe that, the point of intersection of the two lines is (2,2).
Thus, option C is correct.

Work out the ratio of AREA of Rectangle A to Rectangle B in the simplest form.
Multiple choice :
A.) 5 : 3
B.) 3 : 4
C.) 4 : 9
D.) 4 : 11
Answer:
C.) 4:9
Step-by-step explanation:
[tex]10*16=160\\24*15=360\\160:360=4:9[/tex]
Answer:
C
Step-by-step explanation:
Given ratio of sides = a : b , then
ratio of areas = a² : b²
Here
ratio of sides = 16 : 24 = 2 : 3 , then
ratio of area = 2² : 3² = 4 : 9 → C
FIRST CORRECT ANSWER GETS BRAINLIEST! CALCULATE THE SLOPE FOR INTERVAL A.
Answer:
60
Step-by-step explanation:
The slope is going to be rise over run which is feet/seconds
from (0,0) to (600,10) which is a the line rises up 600 feet and runs 10 seconds
so it is just 600/10 which is 60

April and Bill went to the grocery store to buy chocolate bars. April bought 4 small chocolate bars and 6 large chocolate bars , while Bill bought 4 small chocolate bars and 3 large chocolate bars. If April paid $16.50 and Bill paid $11.25, what is the price of a single large chocolate bar?
Step-by-step explanation:
To do this equation, we could put it in terms of algebra, lets say the large chocolate bars are represented by L and the small bars by S
April
4S + 6L = $16.50
Bill
4S + 3L = $11.25
Looking at this, we can see that the difference between the two purchases is that Bill bought three less large chocolate bars, this means the difference in total cost equals three large chocolate bars. Using this knowledge.
$16.50 minus $11.25 = $5.25
$5.25 = Three Large Bars
Divide this by three to get the cost of one large bar.
$1.75 is the cost of one single large bar.
Answer:
April: 4x+6y=16.5
Bill: 4x+3y=11.25
solving the two equations simultaneously will give you y=1.75

Tell whether the angles are adjacent or vertical. Then find the value of x.
Answer:
x = 63°
Step-by-step explanation:
~ They are adjacent angles because they have a common (one) vertex.
~ To find the value of x we must make an equation.
Angles on a straight line add up to 180°.
117 + x = 180
x = 180 - 117
x = 63°
Answer:
63
Step-by-step explanation:
63 is the answer
