Answer:
3
Step-by-step explanation:
The first thing I'll do is solve "5y = 2x + 20" for "<span>y=</span>", so that I can find my reference slope:
y = (2/5)x + 4;
So the reference slope from the reference line is <span>m = 2/5;</span>.
Now I need to find two new slopes, and use them with the point they've given me; namely, with the point (-1, 3). They want me to find the line through (4, –1) that is parallel to 5y = 2x + 20; that is, through the given point, they want me to find a line that has the same slope as the reference line.
Since a parallel line has an identical slope, then the parallel line through (-1, 3) will have slope <span>m = 2/5</span>. Now I have a point and a slope! So I'll use the point-slope form to find the line: y - 3 = (2/5)( x + 1);
Finally, y = (2/5)x + 17/5;
10 3/5=10.6
10.6+12.5=23.1
35.0-23.1=11.9
It is 11.9 miles from Chester to Durbin.
Answer: LCM = 720, GCF = 5 Please consider Brainliest.
Step-by-step explanation:
Find the least multiple of all three numbers, it should be 720. Find the Greatest factor, which should work. But remember, 15 doesn't work because 80 doesn't have 15 as a factor.
Let, number of solid color gift sold is x and printed gift wrap is y.
Also, number of printed paper sold , 325.
Expressing, it in mathematical equation :
y = 325 ....... 1)
Also, The band needs to earn $2,500 for an upcoming competition.
So ,
3.5x + 5y = 2500 ....... 2)
Solving equation 1 and 2 :
3.5x + 5(325) = 2500
3.5x = 2500 - 1625
3.5x = 875
x = 250
Therefore, number of solid paper they must sell is 250.
Hence, this is the required solution.
