Step-by-step explanation:

Answer:

-86

Step-by-step explanation:

-8((-11/4)-8)

((11/4-8)

8x(-43/4)

-2×43=-86

Answer:

There are a lot of turning point in the history of algebra one of those is the discovery of  the plain and the quadrants by Rene Descartes. This discovery paved way to a lot of knowledge which was later on use in solving other complicated mathematical problems.

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

36 ÷ 3 = 12 is basically the division version of the original equation. None of the other equations equal the same answer so B is the correct option.

36 ÷ 3 = 12 is equivalent to 3 • 12 = 36

Answer:

B. 0.21

put in 75% for success rate

4 for the amount of trials because that is the total of kids the couple has

2 for number of successes for how many kids would get Type A blood

once calculated you get.21 or answer B

Answer:

12                                        

Step-by-step explanation: 60

Answer: n=7+1/2

Step-by-step explanation:

We move all terms to the left:

2n+15-(30)=0

We add all the numbers together, and all the variables

2n-15=0

We move all terms containing n to the left, all other terms to the right

2n=15

n=15/2

n=7+1/2

Answer:

18$

Step-by-step explanation:

The answer is 18$ because you multiply 3.60$ by 5 lbs

Answer:

65

Step-by-step explanation:

the square means 90 add that to 25 and subtract from 180

Answer:

x =  65

Step-by-step explanation:

The measure of the entire angle is 180°. The angle on the furthest left (with a square in it) is a right angle, meaning that it is 90°.

All three of the angles (90°, x°, 25°) all add up to the measure of the line, which is 180°. So, we can write this equation.

90 + x + 25 = 180

Subtract 90 and 25 from both sides.

90 + x + 25 - 90 - 25 = 180 - 90 - 25

x =  65

I just took the quick check

$21.00

Step-by-step explanation:

if 1 yard equal 6 dollars

do 6 times 3 = 18

and half of 6 is 3

add 18+3=21 dollars

Answer:

Transitive Property

Step-by-step explanation:

Since X is the midpoint, it bisects the points RS. If MX=XS, and RS is the same as XS, then they are the same. This also follows the Transitive propety  (if a=b and b=c, then a=c)

Answer:

8x-12

Hope it helped plz mark me brainliest PlzPlz

Answer:

8x-12

Step-by-step explanation:

You need to find a number/numbers that have the same variable if the variable is the same then you can add or subtract them

You can add 4x, 3x and 1x

4x plus 3x plus 1x is 8x

Since -12 is alone you can leave it as it is

8x-12

Answer:

5

Step-by-step explanation:

Slope intercept form is y = mx + b

M is the slope

5 is the m

Answer:

5

Step-by-step explanation:

When your trying to find the slope of something you need to use slope intercept form.

Answer:

y=5x-2

Step-by-step explanation:

Answer:

4

Step-by-step explanation:

You need to try out all the numbers.

lets start with 4

if there where 4 red marbles then there would be 9 times as many marbles

so 4 x 9 = 36

Now we add and see if the sum is 40

36 + 4 = 40

We got it on the first try

You can use the same method on more problems like these.

Hope this helps :)

Answer:

x = ±9

Step-by-step explanation:

x² - 55 = 26

   +55   + 55

     x² = 81

     x = √81

     x = ± 9

Answer:

x = 9, -9

Step-by-step explanation:

x^2 - 55 = 26

x^2 = 81.

Now, you might think that x = 9, but don't be fooled. -9 squared is also equal to 81.

So, x = 9, -9

Step-by-step explanation:

Answer:

7.8 = k

Step-by-step explanation:

Since the figures are similar, we can use proportions

c           k

----- = -------

b            j

Substituting the values in

6.5         k

----- = -------

4          4.8

Using cross products

6.5 * 4.8 = 4k

31.2 = 4k

Divide each side by 4

31.2/4 = 4k/4

7.8 = k

Answer:

[tex](\frac{1}{3})(x+5)^2-1[/tex]

Step-by-step explanation:

So first let's write a graph in vertex form with a vertex of (-5, -1)

We get

a(x+5)²-1

We now need to determine a

we know that when x= -2 y=2 which means we have

a(-2+5)²-1=2

Solve for a

a(3)²=3

9a=3

a=3/9

a=1/3

Now that we know what a is equal to we can write our equation

[tex](\frac{1}{3})(x+5)^2-1[/tex]

Answer: D y=20

Answer:

0.88 (I think this is how Mrs. Futch wants it to be written)

Step-by-step explanation:

h=-16t^2+14t

(Substitute h with 0)

0=-16t^2+14t

(Factor)

0=2t(-8t+7)

2t=0               -8t+7=0

t=0                  t=0.88

{0, 0.88}

Answer:

So everyone here in Mrs. Futch?
