42% + 25% + 33% = 100%

42% ------------210
100%................?

210 x 100/42 = 500

answer:  500 people were surveyed

This can be easily set up as a proportion:
 \frac{42}{100} = \frac{210}{n}, such that 42/100 represents 42 percent and 210 is proportionally equivalent to 42, and n is the missing total number of people surveyed.

After cross-multiplication, the answer is 500 people, because 210 is 42% of 500.

Tony needs to buy some pencils.Brand A has a pack of 28 pencils for 5.29 dollars. Brand B has a pack of 48 pencils for 8.47 doll
Shalnov [3]

Answer: Brand A is the best buy.

Step-by-step explanation:

Brand A has a pack of 28 pencils for 5.29 dollars. This means that the unit cost of one pencil in Brand A would be

5.29/28 = 0.2$ per pencil rounded up to the nearest tenth.

Brand B has a pack of 48 pencils for 8.47 dollars. This means that the unit cost of one pencil in Brand B would be

8.47/48 = $0.8 per pencil rounded up to the nearest tenth.

Since $0.2 is lesser than $0.8, it means that Brand A is the best buy.

Carlos and Sophie, factored the trinomial –4x2 − 10x + 6. Sophie factored it as –2(2x − 1)(x + 3) and Carlos factored it as (x +
nydimaria [60]
Sophie factored it completely while Carlos did not.

Complete factoring is achieved when all factors other than monomial factors are prime factors. Carlos' (4x + 2) can still be factored into 2(x+1).
