Answer:
She bought
22 of the 52 cent stamps and
26 of the 23 cent stamps.
Step-by-step explanation:
Given :
Total stamp increase = 48
Let number of 52 cent stamp = x
Number of 23 cent stamp = 48 - x
The cost equation :
0.52*x + 0.23*(48-x) = 17.42
0.52x + 11.04 - 0.23x = 17.42
0.52x - 0.23x = 17.42 - 11.04
0.29x = 6.38
x = 6.38 / 0.29
x = 22
Hence,
She bought 22 ; 52-cent stamps
And (48 - 22) = 26, 23-cent stamps
The answer is 11 because a hexagon gas 6 sides
Answer:
see the explanation
Step-by-step explanation:
we have
<em>Find the x-intercept</em>
Remember that the x-intercept is the value of x when the value of y is equal to zero
For y=0
the x-intercept is the point (2,0)
<em>Find the y-intercept</em>
Remember that the y-intercept is the value of y when the value of x is equal to zero
For x=0
the y-intercept is the point (0,-5)
using a graphing tool
Plot the intercepts and connect them to graph the line
