The simple rules in adding equation is
- simplify like terms first
- then get one variable on one side of the equation
- then solve the rest
Answer:
11 feet, 26 feet, 29 feet
Step-by-step explanation:
(2x+4 middle) + (3x- 4 longest) + (x smallest )= 66
2x +3x +x +4 - 4= 6x
6x = 66
x= 66/6
x = 11
smallest = 11 feet
middle = 2(11) + 4 = 26 feet
longest = 3(11) -4 = 29 feet
Answer:
The answer is below
Step-by-step explanation:
The distance between two points on a coordinate plane is given by:

Given the location of the apartment (AP) is at A(0,0), the Chicken Shack's (CS) location is at C(3, 4) and Baskin Robbins (BR) is at the location B(- 4, 4). Hence the following distance are:

Hence the total distance travelled = distance between the apartment and chicken shack +distance between apartment and Baskin Robbins + distance between Baskin Robbins and chicken shack
total distance travelled = AB + BC + AC = 4√2 + 7 + 5
total distance travelled = 17.66 units
<span>A = 2ab + 2ac + 2bc
A = 2b(a + c) + 2ac
2b(a + c) = A - 2ac
b = (A - 2ac) / [2(a + c)]</span>
<span>To find the answer we must calculate her comission earnings for $45.000 and for the amount she sold above $45.000 (in our case, 51.000 - 45.000 = 6.000). So in total we have 6/100 * 45.000 + 8/100 * 6000 = 2700 + 480 = 3180.</span>
