What is the solution to<br> 6(2 - x)&lt;-4x + 2?
cupoosta [38]

Answer:

Solving 6(2 - x) we get \mathbf{x>5}

Step-by-step explanation:

We need to find solution of 6(2 - x)

Solving the inequality:

6(2 - x)

Multiply 6 with terms inside the bracket

12-6x

Subtracting 12 on both sides

12-6x-12

Adding 4x on both sides

-6x+4x

Divide both sides by -2 and the inequality will be reversed i.e < will be changes to >

\frac{-2x}{-2}>\frac{-10}{-2}\\\mathbf{x>5}

So, after solving 6(2 - x) we get \mathbf{x>5}

Which value of b results in infinitely many solutions for the system?
Tanya [424]

Answer: 3

Step-by-step explanation:

I just finished the test and this was the answer I put and it was right.

9x+6y=b

6y=b-9x

y=b/6 -9/6x

y=b/6-3x/2

y= -3x/2 +b/6

3x + 2y = 1

2y = 1 - 3x

y = 1/2 -3/2x

y = -3/2x + 1/2

b/6=1/2

b=3

Bentley went into a bakery and bought 4 donuts and 10 cookies, costing a total of $23. Skylar went into the same bakery and boug
Dima020 [189]

Answer:

Donuts cost $2.00 and Cookies cost $1.50

Step-by-step explanation:

D = cost of a donut

C = cost of a cookie

4D + 10C = $23.00

8D + 6C = $25.00

Eliminate a variable when subtracting the two equations.  Change both values with C to 60 in order to eliminate the C variable and solve for D.

80D + 60C = $250.00 subtracted from 24D + 60C = $138

56D = $112.00  (Divide by 56 to single out the variable)

56D/56 = $112.00/56

D = $2.00

Use the D value to solve for C.

4(2) + 10C = $23.00

8 + 10C = $23.00

8 - 8 + 10C = $23.00 - 8

10C = $15.00

10C/10 = $15/10

C = $1.50

Check:

Bentley:  

4D + 10C = $23

4(2) + 10(1.50) = $23

8 + 15 = $23

23 = 23

Skylar:

8D + 6C = $25

8(2) + 6(1.50) = $25

16 + 9 = $25

25 = 25
