X-(-5)=-4
What does x equal
Answer:
x = -9
Step-by-step explanation:
x - ( - 5 ) = - 4
Distribute the negative sign
x - ( - 5 ) = - 4
x + 5 = -4
Inverse operations;
x + 5 = -4
-5 -5
x = -9
Answer:
-9
Step-by-step explanation:
X = -4 + (-5) = -9
You can always move elements of equality to the other side by changing either their signs or applying opposite operator: addition <-> subtraction, multiplication <-> division

At a football game, a vender sold a combined total of 198 sodas and hot dogs. The number of sodas sold was two times the number of hot dogs sold. Find the
number of sodas and the number of hot dogs sold.
Answer: 132 sodas & 66 hot dogs
Step-by-step explanation: S=soda H=hot dogs
so 2s + h = 198
= 198 / 3 = 66
66 x 2 = 132 sodas
66 = number of hot dogs

$120.58
Kai needs to replace the strip laminate that is glued to the vertical faces on a square tabletop. The tabletop is 1.69 m2. What length i laminate does he need
Area of a square = Side x Side (length x width)
A = 1.69 m²
Length = √area of square
L = √1.69 m²
L = 1.3 m
Check Work: 1.3² = 1.3 m x 1.3m
= 1.69 m²
Answer:
he needs 1.3 meters of laminate for the length
Step-by-step explanation:
area of a square = side multiplied by side (or length x width)
area = 1.69 m²
Length = √area of square
L = √1.69 m² or 1.3m
Do you think it was moral for European nations to claim lands in the Americas that were already inhabited by natives? Why or why not?
Why did cartographers add artistic pictures, like angels, to their maps?
Answer:
It was immoral for European nations to claim land in the Americas that were already inhabited by natives. This is because some people were displaced and used as slaves.
Step-by-step explanation:
Cartography is defined as the science and art of making maps or graphical representations showing spatial concepts at various scales. Maps convey geographic information about a place and can be useful in understanding topography, weather, and culture, depending upon the type of map.

Explain how to get the variable alone in the equation. 3x = 24
Answer:
to get rid of the 3 on the x you have to divide it by 3. whatever you do to one side you have to do to the other side so the answer would be x=8
Step-by-step explanation:
Answer:
x = 8
Step-by-step explanation:
To get the variable alone you would divide both sides by 3. You do this because 3 is a common factor that both 3 and 24 have. Once you divide 3 on each side, you have x = 8 as your final answer.

Find the missing angle
Answer:
x = 41
Step-by-step explanation:
119 + 76 = 195
236 - 195 = 41
Hey there!
The correct answer is 41
We can see that all angles are a total of 236, so we can subtract the other angles: 236 - 119 - 76 = 41
Hope it helps and have a good day!
I do not know what to put and this was due yesterday
Answer:
Your answer will be x=2
Step-by-step explanation:
Five plus 6 times a number is equal to 21 minus 2 times the number
Your equation is this:
5+6x=21-2x
Subtract 6x from both sides
5+6x-6x=21-2x-6x
5=21-8x
subtract 21 on both sides
5-21=21-21-8x
-16=-8x Divide -8 on both sides
2=x
Hope this helps :)

Use the second derivative test to find the relative extrema for f(x)=x^4-2x^2 + 3
If f(x) = x ⁴ - 2x ² + 3, compute the first and second derivatives:
f'(x) = 4x ³ - 4x
f''(x) = 12x ² - 4
Solve f'(x) = 0 to get the critical points of f(x) :
4x ³ - 4x = 4x (x ² - 1) = 0
→ x = -1, x = 0, x = 1
Check the sign of the second derivative at each of these points:
f'' (-1) = 8 > 0
f'' (0) = -4 < 0
f'' (1) = 8 > 0
These indicate the presence of
• two minima of f (-1) = 2 and f (1) = 2
• one maximum of f (0) = 3
which makes C the correct answer.
What is the length of BC?
Answer:
x = 22, The length of BC is 22
Step-by-step explanation:
It is shown that angle ACB and angle ABC are congruent (The measure of angles are the same) in the picture. Since the angles are congruent, we can say that AC = AB because of base angle theorem converse. We can then substitute the given numbers in for AC and AB. We would then get 2x - 24 = x - 2. If you solve, you would get that x = 22 (The length of BC is 22).
