dmitriy555 [2]
7 out of 10 would vote for Tammy so what value (x) would vote for her out of 230. Set up a proportion comparing the two.

x= # of people who vote Tammy

7 out of 10= x out of 230
7/10= x/230
cross multiply

(7*230)= (10*x)
1610= 10x
divide both sides by 10

161= x


ANSWER: 161 people in 7th grade would vote for Tammy.

What is the final amount if 731 is increased by 7% followed by a 4% decrease? Give your answer rounded to 2 DP.
expeople1 [14]

Answer:

750.88 (rounded to 2 d.p.)

Step-by-step explanation:

100% --- 731

100% + 7% --- \frac{100+7}{100} × 731 = 782.17

100% --- 782.17

100% - 4% --- \frac{100-4}{100} × 782.17 = 750.88 (rounded to 2 d.p.)

A. (4, -7) Is the correct answer!

2 x 4 = 8    8 - 15 = -7   True!

4 x 4 = 16    3 x -7 = -21     16 + -21 = -5    True!

Since both statements are true, this is the solution to the system.
