the answer is 3/n - 5 = -7

The answer to this D=A(c-B)

Answer:

4 x + -43

Step-by-step explanation:

Simplify the following:

7 (x - 4) - 3 (x + 5)

Hint: | Distribute 7 over x - 4.

7 (x - 4) = 7 x - 28:

7 x - 28 - 3 (x + 5)

Hint: | Distribute -3 over x + 5.

-3 (x + 5) = -3 x - 15:

7 x + -3 x - 15 - 28

Hint: | Group like terms in 7 x - 3 x - 28 - 15.

Grouping like terms, 7 x - 3 x - 28 - 15 = (7 x - 3 x) + (-28 - 15):

(7 x - 3 x) + (-28 - 15)

Hint: | Combine like terms in 7 x - 3 x.

7 x - 3 x = 4 x:

4 x + (-28 - 15)

Hint: | Evaluate -28 - 15.

-28 - 15 = -43:

Answer: 4 x + -43

Answer:

4x – 43

Step-by-step explanation:

Answer:

x=2

Step-by-step explanation:

i'm gonna assume that "leg" refers to length of the triangle, so comment if you think it is wrong.

Now when it comes to a right-angled triangle, the pythagoras theorem formula can be used.

Using algebra,

let the missing length be X.

By pythagoras theorem,

5² = 3² + X²

5² - 3² = X²

X² = 5² - 3²

X = sq root ( 5² - 3² )

= 4 m

Therefore, the length of the missing leg is 4m .

Answer:

17.

Step-by-step explanation:

We know that NP = NO + NP because all the points are on the same line.

So 2x = 10 + (x + 7),

x = 17.

Answer: Its 8

Step-by-step explanation:

Simplify numbers to layman terms.

[tex]\frac{\pi}{2}[/tex] will be a little more than [tex]\frac{3}{2}[/tex], since [tex]\pi[/tex] is 3.14.

[tex]-\sqrt{18}[/tex] will be a little less than -4, since [tex]-\sqrt{18}<-\sqrt{16}[/tex].

[tex]\sqrt{18}[/tex] will be a little more than 4, since [tex]\sqrt{18}>\sqrt{16}[/tex]

[tex]-\sqrt{7}[/tex] will be a little less than -2, since [tex]-\sqrt{7}<-\sqrt{4}[/tex]

Now we can order them.

[tex]-\sqrt{18},-\sqrt{7},\frac{\pi}{2},\sqrt{18}[/tex]

Hope this helps.

頑張って!

Answer:

1: negative square root of 18 (-4.2)

2: negative square root of 7 (-2.6)

3: pi/2 (1.57)

4: square root of 15 (3.9)

some are approximate calculations, but you only need the order of from smallest to largest number

Answer:

32 days.

Step-by-step explanation:

56 / 1.75 = 56 / (7/4) = 56 * 4 / 7 = 32.

Answer:

$360

Step-by-step explanation:

i added 20%+20%=40% so you turn 40% into.40 then you multiply 600×.40 to get 240 since it is discounted you have to subtract so you subtract 600-240 to get 360 which is your final product

Answer:

[tex]Y^4[/tex]

Step-by-step explanation:

Given:

Y to the fourth Power

Required

Express using mathematical expression

In mathematics;

To the nth power means raise to the power of n

In this case;

to the fourth Power means raise to the power of 4

Hence;

Y to the fourth Power = Y raise to the power of 4

And this can be represented mathematically as:

[tex]Y^4[/tex]

Answer:

= (- 475)

Step-by-step explanation:

Given:

(-5) × (-5) × ... × (-5) = (-5)95

Find:

Sign of the product

Computation:

(-5) × (-5) × ... × (-5) = (-5)95

= (- 475)

No, it is not compulsory to do all calculation to find sigh of product

Negative number × odd time = Negative number

Negative number × even time = Positive number number

Answer:

He added the exponents instead of multiplying them

Step-by-step explanation:

When a power is raised to a power (in this case, -8 was raised to the -2) the exponents should be multiplied, not added. So instead of j^-10 it should be j^16.

Answer:

See below.

Step-by-step explanation:

1)

Triangle

Perimeter = sum of lengths of the 3 sides

Area = base * height/2

Perimeter = 9 m + 10 m + 11 m = 30 m

Area = 10 m * 8 m /2 = 40 m^2

5)

Parallelogram

Perimeter = sum of lengths of 4 sides.

Hint: opposite side have equal lengths

Area = base * altitude

Perimeter = 9 m + 9 m + 7 m + 7 m = 32 m

Area = 9 m * 6 = 54 m^2

6)

Triangle

Do the same as for problem 1.

8)

Triangle

Do the same as for problem 1.

10)

Parallelogram

Do the same as for problem 5.

Answer:

he won't, he will need more

Step-by-step explanation:

Answer:

Consecutive integers:

x

(x+1)

(x+2)

Now your equation is given by sum of the first and twice the third is equal to four times the second decreased by five:

x+2(x+2) = 4(x+1)-5

Step-by-step explanation:

Answer:

10, 11 and 12.

Step-by-step explanation:

Let the integers be x, x+1 and x+2. Then:

x + x+2 = 22

2x = 22 - 2 = 20

x = 20/2

x = 10.
