<u>Solve</u>

Given

x/7 = 27/9

Simplify

x/7 = 3/1

Cross multiply

x = 21

Hope this helps!! :)

Write an equation in standard form of the line that passes through the given points (-2,6) (-8,-5)
Lunna [17]
Find the slope
m= -5-6 / -8-(-2)
m= -11/-6
m=11/6

Use slope and point to create equation
y-6= 11/6(x-(-2))
y-6=11/6x+22/6
y=11/6x+58/6
y=11/6x+29/3

Change to standard form
Standard form: ax + by = c
-11/6x+y=29/3

Pls help me with this ​
tamaranim1 [39]

Answer:

Step-by-step explanation:

So you start with 5.7 miles which is the first ride and the long ride is 5 2/3 times longer so you multiply 5.7 by 5 2/3. 5.7 is equivalent to 5 7/10 so you multiply 5 7/10 by 5 2/3. If we get common denominators we will end up with 5 21/30 and 5 20/30 then you multiply. You will get 32.3: 32.3 is equivalent to 32 and 3/10. Then you add that to 5 and 7/10. You will get 38.

Answer: 38

Simplify the expression. (3x/y)^-3
AysviL [449]

Answer:

y^3/(27 x^3)

Step-by-step explanation:

Simplify the following:

((3 x)/y)^(-3)

((3 x)/y)^(-3) = (y/(3 x))^3:

(y/(3 x))^3

Multiply each exponent in y/(3 x) by 3:

(y^3)/((3 x)^3)

Multiply each exponent in 3 x by 3:

y^3/(3^3 x^3)

3^3 = 3×3^2:

y^3/(3×3^2 x^3)

3^2 = 9:

y^3/(3×9 x^3)

3×9 = 27:

Answer:  y^3/(27 x^3)
