-5(r - 6) + 3(-8 + 8r) = -32

STEP 1: Simplify both sides of the equation.
(−5)(r)+(−5)(−6)+(3)(−8)+(3)(8r)=−32 (Distribute)
−5r+30+−24+24r=−32(−5r+24r)+(30+−24)=−32 (Combine Like Terms)
19r+6=−3219r+6=−32

STEP 2: Subtract 6 from both sides.
19r+6−6=−32−619r=−38

STEP 3: Divide both sides by 19.
19r/19 = -38/19
r = -2

FINAL ANSWER: r = -2

A car dealership has SUVs and sedans in a ration of 5:9. How many sedans does the car dealership have if there are 140 SUVs

Elza [17]

To solve this, all you need to do is compare the ratio to the amount of SUVS there are.

5/9 (SUVs to sedans)

140/? (SUVs to sedans)

140 ÷ 5 = 28

9 x 28 = 252

140/252

There are 252 sedans in the car dealership! :D

Answer:

Check the explanation

Step-by-step explanation:

kindly check the attached image below to Determine whether the given set S is a subspace of the vector space (which is contained within a different vector space. So all the subspace is a kind of vector space in their own way, although it is also defined relative to some of the other larger vector space. The linear subspace is more often than not simply called a subspace whenever the situation serves to differentiate it from other types of subspaces.) V.A
