A = bh

Divide both sides by h:

A/h = bh/h

A/h = b

Answer:

The sum of a positive integer and a negative integer always being negative is FALSE. Say were adding these two integers together, one of which is postive and the other negative: -5 + 12

-5 + 12 is equal to 7, which is NOT a negative integer.

Hi there!

To find f(-100), substitute in -100 for the x in the function.

f(x) = x/50

Plug in -100 for x:

f(-100) = -100/50

Evaluate:

f(-100) = -2

Division of 34 by 3 :

and remainder = 1

Answer:

X = 50

Step-by-step explanation:

Both equations TOGETHER equal 180 degrees so you write the equation:

2x + 30 + x = 180

(combine X's. Subtract 30 from both sides):

3x = 150

(divide both sides by 3)

X = 50

Answer:

Width= 36 Length=78

Step-by-step explanation:

width= w

length = 2w+6

perimeter = 2(l+w)

228=2(2w+6+w)

228 = 2(3w+6)

228=6w+12

216 =6w

w=36

width= w=36 ft

length = 2w+6 = 2(36)+6=78 feet

Answer:

A= 560mph, B=5,600miles in 10 hours

Step-by-step explanation:

If you divide 3,360 by 6 to get the mph for part a, you’ll then multiply that by 10 to get part b.

3,360 / 6= 560

560*10=5,600

Answer:

$5 per pound of grapes

Step-by-step explanation:

Because 2/5 a pound of grapes cost $2 you would add another $2 for 4/5 pound of grapes. Then, you would divide 2 by 1/2 to get $1.

So 1 pound of grapes = $5

Hope this helps!!    **please give me brainliest :)

The cost of per pound of grapes is $5.

A number juggling activity is determined by consolidating operands with one math administrator. The built-in functions ADD, SUBTRACT, DIVIDE, and MULTIPLY can also be used to specify arithmetic operations.

Both the plus sign and the minus sign can be used as operators with prefixes or infixes. Only infix operators can be used to represent all other arithmetic operators.

Given cost of 2/5 pound of grapes is $2

2/5p = 2

where p = pound

p = (2 x 5)/2

1p = 5

1 pound = $5

Therefore the 1 pound of grapes cost $5.

Divident = Divisior x Quotient + Remainder

(3x³ + 4x² - 2 + 7)  = (x + 2) x (3x² - 2x) + (4x - 5)

(3x³ + 4x² - 2 + 7)  =  (3x³ + 4x² - 2 + 7)

A division is a process of splitting a specific amount into equal parts. 

We have,

(3x³ + 4x² - 2 + 7) ÷ (x + 2)

We will divide using the long division method.

Divident = Divisior x Quotient + Remainder

Divident = (3x³ + 4x² - 2 + 7)

Divisor = x + 2

We will find the quotient and the remainder.

  x + 2 ) 3x³ + 4x² - 2 + 7 ( 3x² - 2x

             3x³ + 6x²                   [ sign is changed, 3x³ = -3x³ and 6x² = -6x²]

                    - 2x² - 5

                   - 2x² - 4x             [ sign is changed, -2x² = 2x² and -4x = 4x ]

                            4x - 5

Quotient = 3x² - 2x

Remainder = 4x - 5

Thus,

Divident = Divisior x Quotient + Remainder

(3x³ + 4x² - 2 + 7)  = (x + 2) x (3x² - 2x) + (4x - 5)

(3x³ + 4x² - 2 + 7)  =  (3x³ + 4x² - 2 + 7)

The three irrational numbers between 15 and 17 can be written as [tex]$\sqrt{231.44}\\[/tex], [tex]$\sqrt{244.57}\\[/tex], [tex]$\sqrt{277.67}\\[/tex].

An irrational number is a number that cannot be expressed as a fraction {p/q} for any integers {p} and {q}.

Given are irrational numbers between 15 and 17​.

Now, we can write -

A = 15² = 15 x 15 = 225

{A} = 225

B = 17² = 17 x 17 = 289

{B} = 289

The irrational numbers between 15 and 17 can be written as the square root of numbers between 225 and 289. So, we can write -

[tex]$\sqrt{231.44}\\[/tex]

[tex]$\sqrt{244.57}\\[/tex]

[tex]$\sqrt{277.67}\\[/tex]

Therefore, the three irrational numbers between 15 and 17 can be written as [tex]$\sqrt{231.44}\\[/tex], [tex]$\sqrt{244.57}\\[/tex], [tex]$\sqrt{277.67}\\[/tex].

Answer:

110°

Step-by-step explanation:

Since all angles on a straight line add upto 180°,

Angle 1 + Angle 2 = 180

Angle 1 + 70 = 180

Angle 1 = 180 -70

Angle 1 = 110°
