Which equations have the same value as 3/5 (30x-15)=72 select 3
const2013 [10]

Answer:

x=4.5

Step-by-step explanation:

Given the equation  \frac{3}{5}(30x-15)=72, we simplify as:

\frac{3}{5}(30x-15)=72\\\\18x-9=72

#We further simplify as multiples of 9(divide by 9 to solve for x):

18x-9=72\\\\2x-1=8\\\\2x=9\\\\x=4.5

Hence, from our simplification  the equation has the same value as x=4.5

Geometry B Unit 6: Surface Area and Volume, Lesson 10: Surface Area and Volume Unit Test?
Blababa [14]

Answer:

B

Step-by-step explanation:

Euler's formula for polyhedra states that

F + V - E = 2

where F is faces, V is vertices and E is edges

Substitute the values given and solve for F, that is

F + 13 - 26 = 2

F - 13 = 2 ( add 13 to both sides )

F = 15 → B

M= 1/2 and point : (4,-3) <br><br> Please help I will give you brainless
Vlad1618 [11]

Answer:

y=1/2x-5

Step-by-step explanation:

We have slope so we just need to find the y intercept.

slope intercept formula is

y=mx+b

(m) is slope

(b) is y int

y=1/2x+b

now apply our given x and y values (4 & -3)

-3=1/2(4)+b

simplify

-3=2+b

subtract 2 from each side

-5=b

put that into our equation

y=1/2x-5
