the expressions a[8x+7] and 4x+3.5 are equivalent. what is the value of a

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).

Answer:

954.07 square inches

Step-by-step explanation:

You multiply all the mesurements together.

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

Answer:47

Step-by-step explanation:

that is a 90 degree angle and FGJ is already 43 so subtract 90 from 43 and you will get the angle for JGH which is 47

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.

Answer:

b, d, e, f

Step-by-step explanation:

Answer:

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

E: 2 x 2 x 2 x 2 x 2 is 32

F: 12 divded by 4 is 3, so then 3 x 3 is 9

Answer:

136

Step-by-step explanation:

the smallest number is 136

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!

Answer:

443.2 grams

Step-by-step explanation:

Each can contains 55.4 grams of protein, and there are 8 cans, so the answer would be 55.4*8 = 443.2 grams.

answer:

which question

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)

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
