What’s the answer??????? Pleaseeeeeeee helppppppppppp
Vinvika [58]

Hello from MrBillDoesMath!

Answer:

Choice A,   18x - 6y = 20


Discussion:

Given line  

-9x + 3y = 12     (M)


Choice A:

18x - 6y = 20  =>          divide both sides by -2

-9x + 3y = -10     (N)


The left hand sides of (M) and (N) are equal implying that right hand sides are equal which further implies 12 = -10.  Contradiction! so the system M and N has no solution.


Thank you,

MrB

Two hours after a truck leaves phoenix traveling 45 miles per hour, a car leaves to overtake the truck. if it takes the car ten
Sergeeva-Olga [200]

Answer:

The correct answer is 54 miles per hour

Step-by-step explanation:

To solve this problem we have to use the formula of

Speed=Distance/time

Both, car an truck made the same distance,  so

Distance car=Speed car*time car

Distance truck =Speed truck*time truck  

Distance car=Distance truck

So Speed car*time car =Speed truck*time truck  

Speed car =Speed truck* time truck /time car

Time truck = time car +2 ( truck leaves 2 hours before)

Time car =10

Speed car =45 miles per hour* 12 /10

Speed car = 54 miles per hour

What value of c makes the equation true? c – 23.7 = 8.5 31.2 15.2 14.2 32.2
fomenos

Answer:

32.2 is your answer for c

Step-by-step explanation:

Note the equation:

c - 23.7 = 8.5

Note the equal sign. What you do to one side, you do to the other. Isolate the c. add 23.7 to both sides

c - 23.7 (+23.7) = 8.5 (+23.7)

c = 8.5 + 23.7

Simplify.

c = 32.2

32.2 is your answer for c
