The answer is y = -5/7x + 4/7! The first step is to subtract the 5x so it’s on the other side of the equal sign. So now the equation is 7y = -5x + 4. Then divide each of them for 7
530(1+.144/12)(.06) = 32.18 so even that is less than 35
So the answer is 31.80
If 30% were perfect, 70% were not perfect. So we know that 70% of the total number of photographs is 210.
p(70/100)=210 multiply both sides by 100
70p=21000 divide both sides by 70
p=300
So there are 300 photographs in all.
True, because of the Triangle Inequality Theorem.
To test if you could construct a triangle, make sure the following inequalities are true.
9 + 4 > 11
9 + 11 > 4
4 + 11 > 9.
