Answer:
33
Step-by-step explanation:
Find the unit rate by dividing 20 by 6 which is 3.3. This is how long it took Emma to read one page. multiply it by 10 and get 33
Answer:
x=10
Step-by-step explanation:
these are similar triangles
8 12
------ = -----------
x+4 2x+1
using cross products
8* (2x+1) = 12(x+4)
distribute
16x + 8 = 12x+48
subtract 12x from each side
16x-12x +8 = 12x-12x+48
4x+8 = 48
subtract 8 from each side
4x+8-8 = 48-8
4x = 40
divide by 4
4x/4 = 40/x
x =10
The difference between 76.82 and 2.761 is 74.059
Y=MX+B
M = slope
B = y intercept (number that intersects with the line in the y axis)
y=-3/4x+2
It starts on the y intercept (2) then we travel to the next point (4 on the x axis)
So we travel 3 spaces down (-3) landing on the origin (0,0) then four spaces to the right (4). Getting the slope of -3/4 (rise over run)
Then just plug in these into the equation
y = -3/4 + 2
A. The linear equation is: y = 60x + 45
B. The graphed equation is shown in the attachment below.
<h3>What is a Linear Equation?</h3>
A linear equation is defined as, y = mx + b, where the initial value = b; unit rate = m; x and y are the variables.
A. In this situation given, we have:
- Total cost = y
- Number of months = x
- Monthly charges = unit rate (m)= $60
- Initial value (b) = $45
Substituting the values into y = mx + b, we would have the equation as:
y = 60x + 45
B. The graph of the equation is shown in the image attached below.
