Your answer would be 46.50 because you would divide 31 in half (for the 50%) then add that to the 31. So 31+15.50= $46.50 hope this helps. If not let me know
Answer:
50º
Step-by-step explanation:
Angle D & B are vertical angles, meaning they are equal in measure.
So if Angle B = 50º, then Angle D must also be 50º.
Hope this helps! Have a great day!
-5(-2b-1)
Collect like terms and simplify
(Multiply the number outside the bracket with the ones in the parentheses/bracket)
(-x-)= +
(+x+)= +
(-x+)= -
(+x-)= -
Basically same signs multiplied = +
Different signs multiplied = -
-5(-2b)= 10b
-5(-1)=5
10b+5 is your answer
Answer:
Step-by-step explanation:
7. Let the price of book be x
:- 8x + 17 = 129
8x = 129 - 17
8x = 112
x = 112/8
x = $14
Each book cost $14
8. Let the number of hours be x
9x + 15 = 87
9x = 87 - 15
9x = 72
x = 72/9
x = 8hrs
He paid for 8hours
9. Let the numbers be x, x +2, x +4,
So. x + x + 2 + x + 4 = 168
3x + 6 = 168
3x = 168 - 6
3x = 162
x = 162/3
x = 54
The smallest number is 54
10. Let the number of books be x
So, x/2 + 6 = 18
x/2 = 18 - 6
x/2 = 12
x = 12 ×2
x = 24
So she has 24 book's before
<span>As for this problem, we will
first establish that the length of the flower bed be represented as x, the
width of the flower bed be represented as x/2 ,and the area of the flower bed
be taken as it is since it is given. We then follow the formula for area which
is length multiplied to width which is:<span>
A = LW
we then
substitute them
34 square
feet = x (x/2)
now all
we need to do is find x first.
34 square
feet = x squared / 2
now do a
cross multiplication
68 square
feet = x squared
then get
the square root of both sides
8.246
feet = x
Since x
is equal to the length of the flower bed, all we have to do to get the width of
it is to divide it by 2. So...
W = x/2
W = 8.246
feet / 2
W = 4.123
feet
<span>And since
the problem asked it to find the width of the flower bed to the nearest tenth
of a foot, the answer would be 4.1 ft.</span></span></span>
