Solve the equation a+b-c=180 for c
Answers
a + b - c = 180
So let’s subtract a and b from both sides:
-c = -a -b + 180
Now, multiply both sides by -1:
c = a + b - 180
Hope this helps!
Answer:
Step-by-step explanation:
we are given the equation a+b-c=180
Now to solve it for c we need to isolate the c
first step can be addition of c to both side
a+b-c+c=180+c
a+b=180+c
now in second step we subtract 180 from both sides to get
a+b-180=180+c-180
a+b-180 = c
c= a+b-180

how would you solve 3x-4=9x-21
Answers
-6x = -17
x = -17/-6
x = 17/6
Subtract 9x from both sides.
3x - 9x - 4 = -21
Add 4 to both sides.
3x - 9x = -21 + 4
Simplify.
-6x = -17
Divide both sides by -6.
x = 17/6 AND 2 5/6

Harvey collects rare marbles. He has 112 marbles in his collection. If he uses Seven Trees to hold all of the marbles, how many marbles will he display on three trays? Is tray hold an equal number of marbles answers at brainly.com
Answers
Final answer:
Harvey has 112 marbles distributed equally across seven trays. Each tray holds 16 marbles, therefore, on three trays, Harvey will display a total of 48 marbles.
Explanation:
Harvey has 112 marbles in his collection and uses seven trays to hold all of the marbles. To find out how many marbles Harvey will display on three trays, we need to divide the total number of marbles by the total number of trays to find out how many marbles each tray holds.
First, divide 112 marbles by 7 trays to find out how many marbles go on each tray. The calculation is as follows:
112 marbles ÷ 7 trays = 16 marbles per tray
Now that we know each tray holds 16 marbles, to find out how many marbles are displayed on three trays, we multiple the number of marbles per tray by the number of trays:
16 marbles per tray × 3 trays = 48 marbles
Therefore, Harvey will display 48 marbles on three trays.
3x-2y=-39 and x+3y=31 solution using elimination
Answers
3x-2y=-39
x+3y= 31
We want to use elimination therefor, we need to either get our x or our y to add together to get zero.
To do this, we will multiply -3 to (x=3y=31)
NEW EQUATION
3x-2y=-39 PLUS
-3x-9y= -93 Equals
Answer: -11y= -54
y= 4.9
Plug in to solve for x (put new y in)
3x-2(4.9)=-39
x= -9.73
First, we must add 2y to both sides.
3x - 2y + 2y = -39 + 2y
3x = 2y - 39
Next, we divide both sides by 3.
3x/3 = 2y - 39/3
Answer: 2/3y - 13
Solving for y on x+3y=31:
First, we must add -x to both of the sides.
x + 3y + -x = 31 + -x
3y = -x + 31
Next, we must divide both sides by 3. (Like last time.)
3y/3 = -x + 31/3
Answer: y = -1/3x + 31/3

Each interior angle of a regular polygon measures 120°. what is the name of the polygon?
Answers
(n - 2) x 180°
now we can substitute 120° into this formula
(n - 2) x 180° / n = 120° (because we're calculating each angle from the polygon, so we need to divide the equation by n)
(180n - 360) = 120n
180n - 120n = 360
60n = 360

420,983 estimate it then estimate 39,932 then you have to add thoes then you have to add that and that and then you have to add 420,983 plus 39,932 and see if your answer is close to the estimate
Answers
By rounding numbers to the nearest large place value, we estimated the sum of 420,983 and 39,932 as 460,000. The exact sum is 460,915, demonstrating that our estimation was a close approximation to the actual value.
Explanation:To estimate the sum of 420,983 and 39,932, we can round these numbers to the nearest ten thousand and thousand, respectively. Rounding 420,983 to the nearest ten thousand gives us 420,000, and rounding 39,932 to the nearest thousand gives us 40,000.
Now, we add the estimated numbers: 420,000 + 40,000 = 460,000.
To find the exact sum of 420,983 and 39,932, we add the two numbers together without estimating: 420,983 + 39,932 = 460,915.
Comparing our estimate of 460,000 with the exact answer of 460,915, we can see that our estimate is very close to the exact amount, showing that our estimation was a good approximation. To find the estimate for 420,983, we round it to the nearest 100,000, which is 400,000. For the estimate of 39,932, we round it to the nearest 10,000, which is 40,000. When we add these two estimates, we get 440,000. Next, we add the actual numbers 420,983 and 39,932, which gives us 460,915. Comparing this with our estimate, we can see that our answer is close to the estimate.
Final answer:
To estimate the sum of 420,983 and 39,932, round each number to the nearest thousand and add them together. Then compare the estimate with the actual sum.
Explanation:
To estimate the sum of 420,983 and 39,932, we can round each number to the nearest thousand. 420,983 rounded to the nearest thousand is 421,000, and 39,932 rounded to the nearest thousand is 40,000. Now, we can add these rounded numbers together: 421,000 + 40,000 = 461,000. This is our estimate for the sum.
Next, we add the actual numbers 420,983 and 39,932 together: 420,983 + 39,932 = 460,915. Finally, we compare our estimate (461,000) with the actual sum (460,915) to see if they are close. In this case, our estimate is slightly higher than the actual sum.
Find the domain and range of the relation and determine whether it is a function. y=x2-3
Answers
If the first coordinate is not repeated, like in this example, were we have only (2, 1) and not also (2, 8), for instance, then the relation is called a function.
A relation sometimes has too many pairs to be expressed by listing all of them. in such cases we use formulas which describe all the pairs.
We are given the relation is [tex]y=x^2-3[/tex]. This means that all pairs of this relation, are such that the second coordinate, is the first one squared, minus 3.
So each pair of this relation is : [tex](x, x^2-3)[/tex]
For any x, [tex]x^2-3[/tex] is only one value,
for example, if x=10, y can only be [tex]x^2-3=10^2-3=97[/tex]
We cannot possibly have both (10, 97) and (10, 16), for example, because the formula does not allow that.
this means 10 does not repeat as a first pair in this relation, and nor does any other value.
this makes the relation a function
The Domain is the set of all possible values x can be. Clearly, x can be any value, because no x makes [tex]x^2-3[/tex] undefined
Answer: The relation is a function, with Domain all real numbers

Use the four-step procedure to solve the following problem. How much water must be added to a gallon of 10% saline solution to create a 2% solution?
Answers
How much water (x liters of 0% saline) must be added to make a 2% saline solution?
.10 * 1 + 0x = .02 * (1 +x)
.1 = .02 + .02x
.08 = .02x
x = 4 gallons of water must be added
Answer:
4 gallons of water should be added in 10% saline solution.
Step-by-step explanation:
Let x gallon of water is added in one gallon of 10% saline solution.
Therefore total volume of 10% saline solution will become (1 + x) gallons
Since concentration of water is 0% so equation will be
0.10(1) + 0(x) = .02(1 + x)
0.10 = 0.02(1 + x)
1 + x = [tex]\frac{0.10}{0.02}[/tex]
x + 1 = 5
x = 5 - 1
x = 4 gallons
Therefore, 4 gallons of water should be added to 10% saline solution to create 2% solution.
