Answer:
[tex]a=0.5[/tex]
Step-by-step explanation:
Divide each term by [tex]8x+ 7[/tex] and simplify.
Hope this helps :)
-ilovejiminssi♡
a(8x + 7) = 4x + 3.5
8ax + 7a = 4x + 3.5
equating coefficients of x : 8a = 4 so a = 1/2
also 7a = 3.5 so a = 1/2
The value of a is 1/2

B,C, E, F
Step-by-step explanation:
B : 5+3 x 4. first you do 3 x 4 which is 12 the + 5 which equals 17
C: I-6+4I first you do -6 + 4 which equals -2 but it is absolute power so it is 2

Solve For This Question
Answer:
28
Step-by-step explanation:
To find the missing side, you need to find the difference of the other sides.
35/10 = 3.5
42/12 = 3.5
So now we do 8 x 3.5 = 28
(4.4+7.6)x-(24/12)x

The principal amount (p) is $100 The interest rate (r) is 5% Time in years (t) is 3
Answer:
115.76
Step-by-step explanation:
I'm going to assume that the interest is compounded annually
We have the following equation
P(1+r)^n
We have
100(1+.05)^3
compute this with a calcuatlor and get 115.7625 which is 115.76

Answer:
A: 479.94/6
B: D, 56.79
C: 79.99 and 56.79
D: Obviously 79.99 is greater than 56.79 so the slope in question A is greater than the slope in B (C)
Step-by-step explanation:
Question A:
For this one we will let x= nights in a hotel and y=cost
We can then just pick two points on the table and plug in the numbers to the formula above
Let's pick the first and last one
our two ordered points are (0,20) (6,499.94)
We can plug this in and get
(499.94-20)/(6-0) which simplified to 479.94/6
Question B:
This equation is in slope intercept form
Slope intercept form is as follows
y=mx+b
where m is the slope and b is the y intercept
we can see that the m value is 56.79 which means D is the answer
Question C:
This is pretty easy
First divide 99.8/2 and get 49.9 and the other answer is just 56.79
Answer:
A: 479.94/6
B: D, 56.79
C: 79.99 and 56.79
D: Obviously 79.99 is greater than 56.79 so the slope in question A is greater than the slope in B (C)

The figure is made up of a semicircle and a triangle. Find the perimeter. Round your answer to the nearest hundredth.
Answer:
Solution:
Here,
The perimeter of of the whole figure is 134.57ft.
Step-by-step explanation:
Here,
The perimeter of semicircle = (22/7) x 25ft
= 78.57ft
Now,
The perimeter of triangle = 7ft + 24ft + 25ft
= 56ft
Again,
The perimeter of whole figure = perimeter of semicircle +perimeter of triangle
= 78.57ft + 56ft
= 134.57ft

x+4=10;x=
I literally dont get it please help
Answer:
x = 6
Step-by-step explanation:
10 - 4 = 6
The x means the number is unkown, well, we know that 6+4=10, so there you go!
Answer:
6
Step-by-step explanation:
x is a mystery number. We don't know what it is, but we know that if you add 4 to it, we get 10. To what number should we add 4 to get 10?
That's right, 6.
A more advanced explanation:
We need to isolate x, so it will be alone on one side of the equation. To do this, we must subtract 4 from the left side of the equation, so it will be x + 0, or x. But we also need to remember that equations always need to be balanced, so we need to subtract 4 from both sides, to get x + 0 = 10 - 4. Simplifying, we get that x = 6.
Hope this helps!
What is the value of the variable in the equation, r-17=22 *
please help me with this for brainliest and a cupcake
Answer:
Step-by-step explanation:
Example
With numbers
18+4=22
18+4−4=22−4
18=18
With variables and numbers
x+4=22
x+4−4=22−4
x=18
We subtract 4 from both sides. Example
Which of the following numbers is a solution to the equation? x = 2, 7, or 8?
14−x=7
Here you are given the numbers 2, 7 and 8. One of these numbers will satisfy the equation. If you don't know the solution right away, you can investigate which of the given numbers gives results in the correct answer by plugging in the different values of x.
Answer: x=7
Example
8x=64
8⋅x=64
Which number should you multiply 8 by to get a product of 64? By using the multiplication table, we know that the number is 8.
8⋅8=64
When we solve an equation, we figure out what value of x (or any other variable) makes the statement true (satisfies the equation).

How do u get the slope?
Slope in fraction form = 3/2
Slope in decimal form = 1.5
============================================================
Explanation:
That table shows the two points (x1,y1) = (-14,-18) and (x2,y2) = (-10,-12).
Each row is a different point.
To find the slope, we subtract the y values to get y2-y1 = -12-(-18) = -12+18 = 6
Then we subtract the x values to get x2-x1 = -10-(-14) = -10+14 = 4
Lastly, we divide the two differences: ydiff/xdiff = 6/4 = 3/2
The slope in fraction form is 3/2, which is equivalent to the decimal form 1.5
------------------------
If you want, you can apply the slope formula like so
m = slope
m = rise/run
m = (change in y)/(change in x)
m = (y2-y1)/(x2-x1)
m = (-12-(-18))/(-10-(-14))
m = (-12+18)/(-10+14)
m = 6/4
m = 3/2
m = 1.5
We effectively are following the same as steps as before, but in this format, it's more of what you might have on your homework if you were to show the step-by-step process. You could also do a visual graph approach as a different option. Often in math there are multiple ways to get the answer.
