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.

Step-by-step explanation:
Lines of symmetry are found when you fold it, and it's exactly the same on both sides of the line that you folded it.
If your teachers ask, no, it cannot be diagonal. The triangles would not match up.
Answer: 2500

Answer:
Step-by-step explanation:
Supplementary angles add up to 180
∠1 + 50 = 180
∠1 = 180 - 50
∠1 = 130
∠3 +50 = 180 {Supplementary}
∠3 = 180 - 50
∠3 =130
⇒∠1 = ∠3 = 130
Answer: the answer is x=36
Step-by-step explanation:
Simplify \frac{1}{8}(x-4)
8
1
(x−4) to \frac{x-4}{8}
8
x−4
.
-\frac{x-4}{8}=-4
−
8
x−4
=−4
2 Multiply both sides by 88.
-x+4=-4\times 8
−x+4=−4×8
3 Simplify 4\times 84×8 to 3232.
-x+4=-32
−x+4=−32
4 Regroup terms.
4-x=-32
4−x=−32
5 Subtract 44 from both sides.
-x=-32-4
−x=−32−4
6 Simplify -32-4−32−4 to -36−36.
-x=-36
−x=−36
7 Multiply both sides by -1−1.
x=36
x=36
