7b - 2b + 3 - 1 = 0
(7b - 2b) = 5b
3 - 1 = 2
Thus:
5b + 2 = 0
5b = -2
b = -2/5 = -0.4
If any side is greter or equal to the sum of the other 2 sides then it is not a triangle.
So A is not a triangle because 24 > 11 + 11
For C 19 = 10 + 9 - not a triangle
D:- 23 > 4 + 7 Not a triangle.
Only B is a triangle
Answer: 137.5 pounds
Step-by-step explanation:
Elijah has 2¹/₂ bags of candy. A single bag of candy weighs 55 pounds so to find the quantity of pounds that Elijah has, multiply 55 by the number of bags that Elijah has:
First convert bags to mixed fraction:
= 2¹/₂ = 5/2
Quantity that Elijah has:
= Number of bags * Weight per bag
= 5/2 * 55
= 137.5 pounds
Let x = amount for dog
let 2/3x-5 = amount for cat
x + 2/3x-5 = 195 combine x's
1 2/3x or 5/3x
5/3x-5 =195 add 5 to both sides
5/3x = 200 multiply both sides by 3
5x = 600 divided both sides by 5
x = 120
the cost of the dog is $120.00
