The picture is kind of grainy but it looks like:
4u = 56
Add 4's to both sides:
4u/4 = 56/4
cross out both 4's on left side and divide on the right:
u = 14
Answer: 11 days
Step-by-step explanation: First, divide 30 by 2.6, round the your answer ones place. 2.6 goes into 30 about 11 times. 11 is your answer.
Answer:
In step 1 subtraction property is used and in step 2 division property is used.
Explanation:
We have the equation 2x + 6 = 22
Step 1
The subtraction property of equality tells us that subtracting the same number to each side of an equation gives us an equivalent equation
So subtracting 6 from both sides
2x + 6 - 6 = 22 - 6
2x = 16
Step 2
The division property of equality tells us that you can divide each side of an equation with the same nonzero number to produce an equivalent equation
So dividing each side by 2.
Answer:
y = -5x/3 + 18
Step-by-step explanation:
The points can be written as;
(x,f(x))
where f(x) is same as y
So the points we have are;
(6,8) and (9,3)
We start by finding the slope or the line connecting the points
m = y2-y1/x2-x1 = (3-8)/(9-6) = -5/3
So now we have the general form of a linear equation as
y = mx + b
where m is slope and b is y intercept
We already have slope and we want to calculate y-intercept
Simply substitute one of the points
(9,3) in this case
9 for x and 3 for y
we have ;
y = -5x/3 + c
3 = -15 + c
c = 18
So the line equation is;
y = -5x/3 + 18
Answer:
7<em>x</em> + 10
Step-by-step explanation:
10 + 8<em>x</em> - 1<em>x</em>
<em>Add or subtract like terms.</em>
10 + (8 - 1)<em>x</em>
10 + (7)<em>x</em>
<em>Rearrange.</em>
7<em>x</em> + 10
