Answer:
x = -1
Step-by-step explanation:
30 = 2.5(10)(-2x) - you multiply by each
30 = 25 - 5x - then pass 25 to the other side and subract
5x = - 5x - then divide 5 / -5
x = -1 - and you have the answer
Answer:
x= -1
Step-by-step explanation:
distribute 2.5 through the parenthese
30=25-5x
move variable to the left hand side an change its sign
5x+30 =25
move constant to the right hand side and change the sign
5x=25 -30
calculate the difference
5x= -5
divide both sides of the equation by 5
x= -1

hello I need help on Number 9
Paying 12$ to whoever can answer this question i created. MUST BE CORRECT
Answer:
x = 10
I used the Interior Angles of a Triangle Rule --The sum of all 3 interior angles in a triangle is always 180°.
(3x + 28) + (5x - 18) + 90° = 180°
Now i can get rid of the parentheses and combine like terms.
3x + 5x + 28 - 18 + 90 = 180
8x + 10 + 90 = 180
8x + 100 = 180
Then i subtract 100 from both sides to isolate x.
8x + 100 - 100 = 180 - 100
8x = 80
Then, i divide both sides by 8 to find x.
8x ÷ 8 = 80 ÷ 8
x = 10
Set up and evaluate the optimization problems. (Enter your answers as comma-separated lists.) Find two positive integers such that their sum is 14, and the sum of their squares is minimized. Find two positive integers such that their sum is 14, and the sum of their squares is maximized.
Answer and Step-by-step explanation:
Let x and y be two positive integers and their sum is 14:
X + y = 14
And the sum of square of this number is:
f = x2 + y2
= x2+ (14 – x)2
Differentiate with respect to x, we get:
F’(x) = [ x2 + (14 – x)2]’ = 0
2x + 2(14-x)(-1) = 0
2x +( 28 – 2x)(-1) = 0
2x – 28 +2x = 0
2x + 2x = 28
4x = 28
X = 7
Hence, y = 14 – x = 14 -7 = 7
Now taking second derivative test:
F”(x) > 0
For x = y = 7,f reaches its maximum value:
(7)2 + (7)2 = 49 + 49
= 98
F at endpoints x Є [ 0, 14]
F(0) = 02 + (14 – 0)2
= 196
F(14) = (14)2 + (14 – 14)2
= 196
Hence the sum of squares of these numbers is minimum when x = y = 7
And maximum when numbers are 0 and 14.

What's the length of side AB in ∆ABC shown?
A. 5
B. √313
C. 6
D. √15
Answer:
The value of x = 5 units.
Step-by-step explanation:
Given the right-angled triangle ∆ABC with the following dimensions
AC = a = 12
BC = c = hypotenuse = 13
AB = b = x
Pythagorean Theorem
For a right-angled triangle with the sides, a and b the hypotenuse c is defined as:
[tex]c=\sqrt{a^2+b^2}[/tex]
Thus, using the Pythagorean Theorem to determine the value 'x',
[tex]b=\sqrt{c^2-a^2}[/tex]
as b = x, so
[tex]x=\sqrt{c^2-a^2}[/tex]
a = 12c = 13so
[tex]x=\sqrt{13^2-12^2}[/tex]
[tex]x=5[/tex]
Therefore, the value of x = 5 units.

if 4 oranges make 1 cup of juice then how much will 6 oranges make
Answer:
1 and 1/2 cups
Step-by-step explanation:
4 oranges = 1 cup
6 oranges / 4 oranges in a cup = 1 1/2 cups
If 4 oranges make 1 cup of juice, then that means 1 orange makes 1/4 cup of juice.
So we know that each orange makes 1/4 cup of juice. We need to find how much juice 6 oranges will make. To do that, multiply 1/4 by 6.
1/4 times 6 equals 6/4 or 1 and 1/2.
6 oranges will make 1 and 1/2 cups of juice.

15pts. Please Answer, Im Checking If I Am Correct Is It 8.40? A box of 100 sanitizing wipes costs $12 . How much does one wipe cost?
Answer:
Each wipe costs .12¢
Step-by-step explanation:
I think you would have to divide $12 by 100 because the are 100 wipes and that equals 0.12
Answer:
$0.12
Step-by-step explanation:
One box of wipes contains 100, which costs 12 dollars.
The price for one wipe would be the total price, $12, divided by the 100 wipes. Therefore,
12 / 100 = $0.12 each

Ms. Erickson is going to see the hot air balloons in Albuquerque, New Mexico.
She found out that for every 5 balloons in the sky, 2 of them will be rainbow colored.
If there are 150 balloons in the sky, how many will be rainbow colored?
Answer:
60
Step-by-step explanation:
You have to multiply the top and bottom of the fraction (2/5) by 30 so the denominator will be 150. You also have to multiply the top by 30 (2 times 30). The answer is 60 will be rainbow colored!
2 x 30 = 60
5 x 30 = 150
