-(3x - 2) = -4(x + 1) - 4

-3x + 2 = -4x - 4 - 4

-3x + 4x = -4 -4 - 2

love history [14]

Answer:

3. i think 15.5

4. 140*

Step-by-step explanation:

in number 4, d is a vertical angle to the angle measured at 140.

in number 3, QV=SV, so 17=4x-1     18=4x    18/4=x   x=4.5

and TS=TQ, so 3(x) + 2 = 3(4.5) + 2 = 13.5 + 2 = 15.5 =TQ

Question 11
Anarel [89]

Answer:

the trainee calculated the incorrect amount

It should be 0.5 mL

Step-by-step explanation:

The physician orders penicillin 500,000 units for a patient while the concentration of the drug you have is 1,000,000 units/ 1mL. It's clear that 1mL drug is too much for the patient since 1,000,000 units are higher than 500,000 units.  

The amount of penicillin in 1.5 mL will be definitely higher than 1,000,000 units, so it must be a lot higher than the physician's orders. We can roughly guess that the trainee draws an incorrect amount.

To calculate the exact volume you need, you have to divide the amount of the drug you need with the concentration of the drug. The calculation will be:

the volume needed = amount of the drug you need/ concentration of the drug

volume needed =  500,000 units / (1,000,000 units/ 1mL)= 1/2 mL = 0.5 mL

3/4 cup of sugar required to make 1/3 batch of cookies

Build equation:

\sf \rightarrow \dfrac{1}{3}x  = \dfrac{3}{4} \ cup \ of \ sugar

Solve:

\sf \rightarrow x  = \dfrac{3(3)}{1(4)}

\sf \rightarrow x  = \dfrac{9}{4}

\rightarrow \sf  x = 2\dfrac{1}{4}

What does this mean? and how can y =x or what us the answer to y=x I need help
Readme [11.4K]
At the end of the directions, it talks about parallel, perpendicular, or neither. When x=y, the lines are perpendicular and have infinite solutions. When they are parallel, there is no solution. You'll get an answer like 4=5. Neither means there is only one answer, and you will get one x and one y.
