Answer:
C. 2c+12
Step-by-step explanation:
"12 more than 2 times the number of cats" means "12 + 2c", where c is the number of cats.
To get 2 times, we multiply by 2. To get 12 more, we add 12.
Answer:
slope = -4/5 y-intercept = 1
Step-by-step explanation:
y = -4/5+1
Linear combination method just means to add the equations so that one variable with cancel. In this case the a values are already set up so that they will cancel.
2a + 3b = 1
-2a + b = 11
4b = 12
b = 3
now put 3 back into either of the original equations and solve for a.
2a + 3(3) = 1
2a + 9 = 1
2a = -8
a = -4
(-4,3)
Answer:
Given:
Two trail maps:
Trail on the first map = 8 cm
Trail on the second map = 6 cm
Scale on first map = 1 cm : 2 km
A) What is the scale factor from the map to the actual trail?
For the first map, the scale factor is 1 cm: 2km. Therefore the actual trail is 8 centimeters * 2 kilometers = 16 km.
The scale factor of the second map is 16 km / 6 cm = 2.67 km : 1 cm
B) The length of the actual trail is 16 kilometers.
Step-by-step explanation:
Answer:
The first step is to multiply by a power of 10, so the divisor is a whole number.
