Answer:
The width is 18cm
Step-by-step explanation:
If the equation of the area of a rectangle is:
Area = length * width
Then you substitute in the values you know:
144 = 8 * width
To find the width you need to rearrange the formula to make the width the subject. Do this by dividing the area by the length:
Width = 144 / 8
Width = 18
So the width is 18cm

Answer:
x=1
Step-by-step explanation:
4x+6=10
4x+10-6
4x=4
x=1
Did you you get the answer to this one?
Answer:
4y = 3x + 4
3x-4y = -4 is correct
Step-by-step explanation:
This is what we do.
We first express the first equation in the form;
y = mx + c
where m represents the slope of the line
Thus we have;
4y = 3x -7
divide through by 4
y = 3/4x -7/4
Thus the slope here is the coefficient of x which is 3/4
Now, since the lines are parallel, it means that their slopes are equal
So the slope of the other line too is 3/4
We now use the point slope form to find the equation of this other line
Mathematically, that would be;
y-y1 = m(x-x1)
where (x1,y1) = (-4,-2)
Substituting this into the point slope equation, we have;
y-(-2) = 3/4(x-(-4))
y + 2 = 3/4(x + 4)
Cross multiply
4y + 8 = 3x + 12
4y = 3x + 12-8
4y = 3x + 4
Shop #1 has the best price for 21 pizzas because it is $105, while Shop #2 costs $147 for 21 pizzas which is a lot more money. they would save $42, which is 147-105=42. hope this helps:)
