Answer: x = -7
Step by step
3x+17+5x=7x+10

8x+17=7x+10

8x-7+17=10

8x-7x=10-17

x=10-17

x= -7

Can some one help me i need help it is 6x-1/5=3/1 but its not hole numbers

baherus [9]

X = 8/15
6x - 1/5 = 3/1
6x - 1/5 = 3
6x = 3 + 1/5
6x = 15 + 1 over 5
6x = 16/5
x = 16/30
Then, you simplify.
x = 8/15

Find the constant proportionality (r) using the value for r, enter an equation in the form of. C=rg that represents the relation

CaHeK987 [17]

Answer:

3.333

C = 3.3333g

Step-by-step explanation:

Given the relation : C = rg

C = Total cost of gasoline

g = Number of gallons of gasoline used

r = constant of proportionality

Picking any point on the graph :

At cost, c = $30

Number of gallons of gasoline used, g = 9

Putting the values into our equation :

C = rg

$30 = r * 9

30 = 9r

Divide both sides by 9

30/9 = 9r / 9

3.333 = r

Hence, constant of proportionality, r = 3.333
