Which of the value of x satisfies the equation below -2x-7=12

Masteriza [31]

Answer is A.
You start by adding the 7 to the opposite side. Giving you 19. You divide both sides by -2 which gives you x on one side and -9.5 on the other.

-2x-7=12
-2x=12(+7)
-2x=19
x=19/-2
x=-9.5

You know of a relative who is addicted to pain killers. Due to his history, 2.3g of Tylenol per day is dangerous. He takes 200 m

Nezavi [6.7K]

Answer: So, your relative takes N tablets each 6 hours. a day has 24 hours, and 24/6 = 4, so he takes N tablets 4 times per day, so he takes 4*N tablets.

each tablet has 200mg, and 2.3 g (or 2300 mg) is toxic.

this means that 4*N*200mg must be less than 2300, if we are seeking for the maximum N possible, then:

4*N*200mg = 2300mg

4*N = 2300/200 = 11.5

N = 11.5/4 = 2.87

if you round up this number, you will end up taking more than 2.3g of tylenol per day, this implies that N must be equal to 2.

So your relative needs to take maximum 2 tablets per day.

How to solve 4/7y-2 = 3/7 + 3/14

lisabon 2012 [21]

Solution

1) Simplify $\frac{4}{7y}$ <span> to </span> $\frac{4y}{7}$
$\frac{4y}{7}$ <span>−2= </span> $\frac{3}{7}$ + $\frac{3}{14}$

2) Simplify $\frac{3}{7}$ + $\frac{3}{14}$ <span>to <span>914</span>
</span> $\frac{4y}{7}$ <span>−2= </span> $\frac{9}{14}$

3) <span>Add 2 to both sides
</span> $\frac{4y}{7}$ = $\frac{9}{14}$ <span>+2
</span>
4) Simplify $\frac{9}{14
}$ <span><span>+2</span> to </span> $\frac{37}{14}$
$\frac{4y}{7}$ = $\frac{37}{14}$

5) <span>Multiply both sides by 7
</span><span>4y= </span> $\frac{37}{14}$ <span>×7
</span>
6) Simplify $\frac{37}{14}$ <span><span>×7</span> to </span> $\frac{259}{14}$
$\frac{4y}{7}$ = $\frac{259}{14}$

7) Simplify $\frac{259}{14}$ <span> to </span> $\frac{37}{2}$
$\frac{4y}{7}$ = $\frac{37}{2}$

8) <span>Divide both sides by 4
</span>y= $\frac{37}{2}$ <span>×4
</span>
9) <span>Simplify <span>2×4</span> to 8
</span><span>y=</span> $\frac{37}{8}$
<span><span>
Hope this helps
