Answer: x=4 and BC=20
STEPS:
Set the equation for AC and DF equal to each other then solve for x.
2x+7=5x-5
Eliminate the -5 by adding it to both sides.
2x+12=5x
Move the x to one side by subtracting 2x from both sides.
12=3x
Isolate the x by dividing both sides by 3
4=x
EF=5x which means BC=5x
5(4)= 20
So BC= 20
Answer:
168miles
Corrected question;
12. Raymond is reading a road map. On the map, 1/4- inch represents 12 miles. Approximately
how many miles apart are two cities that are 3 1/2 - inches apart on Raymond's map?
F. 12
G. 48
H. 96
J. 132
K .168
Step-by-step explanation:
Given;
1/4 inch = 12 miles
3 1/2 = 7/2 = 14/4 inch
number of 1/4 inch in 14/4 inch is;
14/4 ÷ 1/4 = 14
14/4 inch = 12×14 miles = 168miles
7. 2; 8. 1/4; 10. -25; 12: -3
(remember to use rise over run method and notice the position of each linear slope)
hopefully that helped! <3
Isometric graph paper is a triangular graph paper which uses a series of three guidelines forming a 60° grid of small triangles. The triangles are arranged in groups of six to make hexagons.
