Answer:
16 (units)
Step-by-step explanation:
3.2n
n is a variable, so when you let n = 5, you substitute.
3.2n = 3.2 * 5 = 16 (units)
Answer:
x = 10/3
Step-by-step explanation:
6=2(x+8)-5x
Distribute
6 = 2x+16-5x
Combine like terms
6 = 16-3x
Subtract 16 from each side
6-16 = 16-16-3x
-10 = -3x
Divide by -3
-10/-3 = -3x/-3
10/3=x
Answer:
-1.43
Step-by-step explanation:
6=2(x+8)-5x
take 2 and deposit it into the parenthesis thatll give you
6=2x+16-5x
next you combine like terms so add 5x to both sides to cancel -5x then you get
6=7x+16
then you take subtract 16 on both sides which will give you
-10=7x
finally you divide 7x on both sides to get x by itself which will give you your final answer of...
-1.43=x
y= -2x-9 is in standard form itself with slope m = -2 and y intercept c as -9.
What is a linear equation?
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
Let, consider the equation of y = mx+c,
where, m is the slope of line and c is the y - intercepts. So to draw the graph firstly we find the two points to connect the line in which first is y-intercepts by putting x=0 in the given equation.
standard form of linear equation is :
y = mx+c
comparing it with given equation :
y= -2x-9.
m = -2, c = -9
Therefore, y= -2x-9 is in standard form itself with slope m = -2 and y intercept c as -9.

standard form for a linear equation means
• all coefficients must be integers, no fractions
• only the constant on the right-hand-side
• all variables on the left-hand-side, sorted
• "x" must not have a negative coefficient
2x + y = -9.
15. y = 2
16, 2x - y = 5
17. y - 1 = =(x + 3)
Answer:
Step-by-step explanation:
14. x=4
vertical line(no slope) with one coordinate being (4,0)
15. y=2
horizontal line(no slope) with one coordinate being (0,2)
16. 2x-y=5
slope= 2; two coordinates are (0,-5) and (2,-1)
17. y-1=(x+3)
slope= 1; two coordinates are (-4,0) and (0,4)
HOPE THIS HELPS!!! :)
Answer:
35
Step-by-step explanation:
Answer:
The answer is 35
Step-by-step explanation:
When we divide two fractions, such as 1/7 ÷ 1/5, we flip the second fraction and then we simply multiply the numerators with each other and the denominator with each other.
We also simplify the answers to fraction problems whenever possible.
How many pieces of fabric are left over?
How many more pieces of fabric would you need to increase the size of the wall hanging?
The square wall hanging made from pieces of fabric will have an area of 1600 square inches. There will be 16 pieces of fabric left over. 1 more piece of fabric is needed to increase the size of the wall hanging.
The first thing to do in this process is to determine how many square pieces of fabric you can use to form a larger square. In order to have a square, you need the same number of pieces on each side, so the number of pieces used must be a perfect square. The largest perfect square less than or equal to 80 is 64 (which is 8^2), so you would use 64 pieces to form the wall hanging.
Therefore, the area of the wall hanging (which is side squared) is therefore 8 pieces x 5 inches x 8 pieces x 5 inches = 1600 square inches.
To find out how many pieces are left over, you subtract the number of pieces used from the total you started with, therefore 80 - 64 = 16 pieces of fabric are left over.
To increase the size of the wall hanging by one row and column (which remains a square), you would need to go up to the next perfect square which is 9^2 = 81, so you need 81 - 80 = 1 more piece of fabric.
