X - 9 = 3/5x 
x - 0.6x = 9
0.4x = 9
     x = 22.5
22.5 - 9 = 13.5

Therefore, Steven will have $13.50. 
Im not entirely sure. You have to recheck this with someone else. Im having a brain fart right now lol

Total money * fraction = part
x* \frac{3}{5} =9 \\ ( \frac{5}{3}) * \frac{3x}{5} = 9* \frac{5}{3} \\ x= \frac{45}{3} =15

Reword this plz The average test score for the science class after completing test 2 is 84.
eduard

Answer:

Given : The linear function f(x) = 0.2x + 79 represents the average test score in math class, where x is the number of the test taken.

The linear function g(x) represents the average test score in your science class, where x is the number of the test taken.

To Find : test average for math class after completing test 2

test average for science class after completing test 2

Which class had a higher average after

completing test

Solution:

f(x) = 0.2x + 79

=> f/2) = 0.212) + 79 = 79.4f(x) = 0.2x + 79

=> f(4) = 0.2(4) + 79 = 79.8

test average for math class after completing test 4 = 79.8 =

1 1 2 3 4 g(x) 86 84 82 80

Х

g(2) = 84

test average for science class after completing test 2 = 84

g(4) = 80

test average for science class after completing test 4 = 80

80 > 79.8science class has more average than

1/4+1/2 find the sum using number line
Arte-miy333 [17]
It's 3/4

no number line provided for me, but if you find the common denominator (4), and convert 1/2 into 2/4, then adding 2/4+1/4 is easy, and equals 3/4

Can you guys help me with this?
Blababa [14]

Answer:

We have been given many sequences below:

The sequence is said to be geometric if there is same ratio between consecutive terms

\frac{a_n}{a_{n-1}}

So we will check all the sequences one by one:

(1) \frac{-9}{-2.7}=\frac{10}{3}

\frac{-30}{-9}=\frac{10}{3}

\frac{-100}{-30}=\frac{10}{3}.

Hence, geometric

(2) \frac{2.5}{-1}=-2.5

\frac{-6.25}{2.5}=-2.5

\frac{15.625}{-6.25}=-2.5

Hence, geometric.

(3) \frac{9.2}{9.1}=0.010

\frac{9.3}{9.2}=0.010

\frac{9.4}{9.3}=0.010

Hence, geometric.

(4) \frac{0.8}{8}=0.1

\frac{0.08}{0.8}=0.1

\frac{0.008}{0.08}=0.1

Hence, geometric.

(5) \frac{-4}{4}=-1

\frac{-12}{-4}=3

Ratio is not same hence, not geometric.
