Solve for x in the following equation.
Marta_Voda [28]

An equation is formed of two equal expressions. The value of x in the given exponential equation is 10. The correct option is 10.

<h3>What is an equation?</h3>

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

In the given exponential equation 5^{x-2}=5^8, It can be observed that the base of both the sides of the equation is the same, therefore, 5. Therefore, the equation can be written as,

5^{x-2}=5^8

Since the base on both the sides are the same, comparing the exponential values on both sides,

x - 2 = 8

x = 8  + 2

x = 10

Hence, the value of x in the given exponential equation is 10.

The MD orders 50mg of an elixir to be given every 12 hours. Available is 125mg/5ml. How much should be administered every 12 hou
Jet001 [13]
FORMULA

D ( desired dose) x V ( vehicle- tablet or liquid)

H ( dose on hand)

D = Dose ordered

H = dose on hand or dose on container label

V = form and amount in which drug comes ( tablet, capsule, liquid)

D= 50mg H= 125mg V= 5ml

50 x 5

125

250 divided by 125 = 2ml

So, 2ml of elixir is administered every 12 hours :) brainliest pls

Christina had a total of $120 to spend while shopping. She already spent $68 on clothes . She wants to buy some video games that
avanturin [10]

Answer:

5 video games.

Step-by-step explanation:

In order to find the total number of video games that Tracy can buy with the money, she has we first need to find how much money she has left after buying the clothes. To do this we subtract the amount she spent on clothes by the initial total that Christina had.

120 - 68 = 52

Now that we know Christina has a remaining $52, we can divide this amount by the value of each individual game ($10) in order to calculate how many she can actually afford.

52 / 10 = 5.2

Finally, we can see that she can afford to only buy 5 video games.

Solve this equation: 80 = 3y + 2y + 4 + 1.
Verdich [7]
Let us first write down the given equation.
80 = 3y + 2y + 4 + 1
80 = 5y + 5
80 - 5 = 5y
75 = 5y
Just reversing both sides we get
5y = 75
Now dividing both sides by 5 we get
y = 15
So the value of y is 15. I hope the procedure for solving the problem is clear to you. In future you can solve such problems with ease following the procedure described.
