Solve the equation a+b-c=180 for c
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
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?
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.

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
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.

what is 4 less than three sevenths of y written as an algebraic expression
The algebraic expression for 'four less than three sevenths of y' is (3/7)y - 4. This involves finding three sevenths of y and then subtracting four.
Explanation:The phrase 'four less than three sevenths of y' is asking us to first find three sevenths of y, and then subtract four from that number. In algebra, this is represented as (3/7)y - 4. The expression (3/7)y means 'three sevenths of y', and the '- 4' indicates we are finding 'four less than' this quantity.

What is the equation of the following graph? Write it in both slope-intercept form and standard form.
The equation of the graph is y = 3x + 9 in slope-intercept form and 3x - y = -9 in standard form.
Explanation:The equation of the graph can be written in slope-intercept form (y = mx + b) and standard form (ax + by = c).
Slope-intercept form: y = mx + bGiven slope (m) = 3 and y-intercept (b) = 9Substituting the values, the equation becomes: y = 3x + 9Standard form: ax + by = cRearranging the equation from slope-intercept form, we get: 3x - y = -9Learn more about Equation of a straight line here:https://brainly.com/question/31693341

The set of ordered pairs represent a function. Write a rule that represent the function. (0,0), (1,6),(2,24), (3,54),(4,96)
The required function would be f(x) = 6x² which represents the set of ordered pairs.
What is a function?The function is defined as a mathematical expression that defines a relationship between one variable and another variable.
We have been given that function as sets of ordered pairs :
(0,0), (1,6), (2,24), (3,54), (4,96)
First, we must identify a pattern. It appears that all yₓ values are multiples of 6.
We can divide yₓ by 6x since it is a multiple of 6 and a multiple of x:
y₁/ 6×1 = 1
y₂/ 6 ×2 = 2
y₃/ 6 ×3= 3
y₄/6×4 = 4
We can clearly see a pattern here ;
y/ 6×x = x
y = x × x × 6
y = 6x² = f(x)
Therefore, the required function would be f(x) = 6x² which represents the set of ordered pairs.
