Step-by-step explanation:
70-25.36= 44.64 (the amount of money she spent)
44.64/7.44 (per pound cost)= 6
The expression for the inequality is:

We need to find which line represents this inequality. To do that we will use the left side of the inequality and rewrite it as a slope-intercept form. Which is done below:

The line for this inequality is "-5x -2". Where the slope is -5 and the y-intercept is -2. We can graph it as shown below:
Answer:
Step-by-step explanation:
4x-8<5x+4
4x<5x+12
-x<12
flip sign
x > -12
Answer:
3 : 4
Step-by-step explanation:
Men = 40, Women = 30
Ratio of women to men

The area of a circle is A = πr^2. We let A1 And A2 the areas of the circles and r1 and r2 the radius of each, respectivley.
A1 + A2 = 80π
Substitute the formula for the area,
π(r1)^2 + π (r2)^2 = 80π
From the statement, we know that r2=2(r1).
<span>π(r1)^2 + π (2 x r1)^2 = 80π
</span>We can cancel π, we will have
5 x (r1)^2 = 80
Thus,
r1 = 4 and r2 = 8
