Answer:
g
Step-by-step explanation:
F=??
4 vertices mean V=4
6 edges mean E=6
4-6+F=2
-2+F=2
F=4
Answer:
The number of dogs that had both Lyme disease and arthritis is 18
Step-by-step explanation:
Let x represent dogs that have both Lyme disease and arthritis
Dog with only Lyme disease = 42 - x
Dog with only arthritis = 96 - x
The sum of the 3 category should give 120
x + (42 - x) + (96 - x) = 120
Collect like terms and solve
x - x - x + 42 + 96 = 120
-x + 138 = 120
138 - 120 = x
x = 18
Dog with only Lyme disease = 42 - x = 42 - 18 = 24
Dog with only arthritis = 96 - x = 96 - 18 = 78
Therefore, the number of dogs with both Lyme disease and anthritis is 18.
Answer:
y=4
Step-by-step explanation:
Let's solve your equation step-by-step.
5y−14=2y−2
Step 1: Subtract 2y from both sides.
5y−14−2y=2y−2−2y
3y−14=−2
Step 2: Add 14 to both sides.
3y−14+14=−2+14
3y=12
Step 3: Divide both sides by 3.
3y/3=12/3
y=4
