Answer:
x=8
x=-2
Step-by-step explanation:
∣x−3∣+4=9
= ∣x−3∣=5
<u>Positive term: (x-3)</u>
(x-3) = 5
Rearrange and Add up
x = 8
<u>Negative term: -(x-3)</u>
Multiply
-x+3 = 5
Rearrange and Add up
-x = 2
Multiply both sides by (-1)
x = -2
Answer:
-5
Step-by-step explanation:
3(4)+x=7
12+x=7
x=-5
Answer:
The dimensions of the garden is 21.5 ft by 114.5 ft
Step-by-step explanation:
Here, we want to find the dimensions of a rectangular garden.
From the question, we are told that the length is 7 feet more than 5 times the width.
Let the length be l and the width be w;
Thus, mathematically;
l - 7 = 5w
l = 5w + 7
Mathematically;
Perimeter of rectangle = 2(l + w)
Hence;
2(l + w) = 272
divide both sides by 2
l + w = 136
but l = 7 + 5w
7 + 5w + w = 136
7 + 6w = 136
6w = 136-7
6w = 129
w = 129/6
w = 21.5 ft
But,
l = 5w + 7
l = 5(21.5) + 7
l = 114.5 ft
Since she donates 25%, take 25% and multiply it by 1,200
