Answer:
5/6
Step-by-step explanation:
to add fractions they need to have a common denominator
make 1/3 have a denominator of 18
1/3(6) = 6/18
9/18 + 6/18 = 15/18
15/18 can be simplified to 5/6
Answer:
25 people
Step-by-step explanation:
c = 5p + 220
345 = 5p + 220
-220 -220
125 = 5p
/5 /5
25 = p
Answer: 1,632.571428571429~ 1,633 people
By using the data of only 12 people out of 252 were blood type A, we can set up an equation to solve this question. Since we are trying to find x amount of people in this situation. We will write
12 x
——- = ———
252 34284
Cool! Let’s go, then let’s use the cross multiplication method, so 12•34284=411408
Then let’s do 252 times x which is just 252
Finally we get 411408/252 which gets approximately 1,633 people.
Hopefully this helped! Love youuuu

Hello! Remember you need to write complete questions in order to find good and exact answers. Here your question is incomplete so I could help you in a general way. Recall that two angles are complementary if and only if they add up to 90°. So, if we have to angles, namely:
∠A and ∠B
And angle ∠A = 35°, then this is complementary to ∠B as the following form:
∠A + ∠B = 90°
∴ 35° + ∠B = 90°
∴ ∠B = 90° - 35°
∴ ∠B = 55°
Finally, ∠A and ∠B are complementary because they add up to 90°
