Answer:
$989.23
Step-by-step explanation:
The cost will be the product of the area in square feet and the cost per square foot.
The area of a trapezoid is given by the formula ...
... A = (1/2)(b1 +b2)h . . . . . where b1 and b2 are the base lengths, h is the height
Filling in the given information, the area is ...
... A = (1/2)(73 ft +114 ft)(46 ft) = 4301 ft²
Since each square foot costs $0.23, this number of square feet will cost ...
... (4301 ft²)×$0.23/ft² = $989.23
The landscaper will charge $989.23 to put sod on the backyard.
Answer:

And we can subtract 4x in both sides and we got:

Now we can subtract in both sides 16 and we got:

And if we divide both sides by 4 we got:

And the best solution would be:
-7
Step-by-step explanation:
For this case we assume the following equation:

And we can subtract 4x in both sides and we got:

Now we can subtract in both sides 16 and we got:

And if we divide both sides by 4 we got:

And the best solution would be:
-7
7b-6(11-2b)=10
The first step is to distribute. Multiply each number inside the parentheses by -6.
7b + (-6*11) + (-6*-2b) = 10
7b - 66 + 12b = 10
Now combine like terms.
19b - 66 = 10
Add 66 to both sides.
19b = 76
Divide both sides by 19.
b = 4
The answer is b = 4.
Answer:
x=6
Step-by-step explanation:
2(x-4)+x=10
expand into 3x-8
add 8 to both sides 3x-8+8=10+8
simplify 3x=18
divide both sides by 3 3x/3=18/3
simplify x=6
