Answer:
x = -4
Step-by-step explanation:
Move all terms that don't contain x to the right side and solve.
We know that
1 Kg is equals to--------------> 1000 g
so
X Kg------------------------> 300 g
X=300/1000------> x=0.30 Kg
if 2 Kg cost--------------> <span>£7.20
0.30 Kg-------------> X
X=0.30*7.20/2------> x=1.08
the answer is
</span>£1.08
Answer:
1. height: 18√2 ≈ 25.46 inches; length: 36√2 ≈ 50.91 inches
2. length: 27 inches; width: 24 inches
Step-by-step explanation:
1. The area of a triangle is given by ...
A = 1/2bh
where b represents the base length, h represents the height.
Filling in the numbers, we get ...
648 in² = 1/2(2h)(h)
h = (√648) in = 18√2 in ≈ 25.46 in
The height is 18√2 inches, about 25.46 inches; the base is 36√2 inches, about 50.91 inches.

2. The area of a rectangle is given by ...
A = lw
where l represents the length, and w represents the width.
Filling in the numbers, we get ...
648 in² = (w+3)(w)
w² +3w -648 = 0 . . . . . . . rearrange to standard form
(w -24)(w +27) = 0 . . . . . . factor
The positive value of w that makes a factor zero is 24.
The length of the poster is 27 inches; the width is 24 inches.
Answer:
the answers is 95 dollers
-3(5/6)v - 1 = -6(3/4)
To start off, we can simplify by multiplying the fractions with their whole numbers.
-15/6x - 1 = -18/4
Further simplify
-5/2x - 1 = -9/2
Now we can multiply everything times 2 to get rid of the fractions
-5x - 2 = -9
Now we will isolate the x value. Add 2 to both sides.
-5x = -7
Finally, divide all by -5 to get the final answer.
x = 7/5
