35x+10. How do I solve this?
kicyunya [14]

Hey there Bfarrar07 !

This is pretty simple when you think about it.

With algebra problems like this, you want to set it equal to zero.

So your first step is to take 35x + 10 and set it equal to zero.

35x + 10 = 0

Then bring the 10 to the other side by subtracting it, so you have something like this:

35x + 10 (-10) = -10 (Remember, what you do to one side you have to do to the other!) So when you take 10 from the left, you have to take ten from the right.

You now have 35x = -10

In order to get x by itself, you need to divide the problem by 35.

35x/35 = -10/35

On the left hand side, the 35's cancel out, so you're left with x.

And on the right hand side you have -10/35

So x = -10/35 (Don't forget to simplify!)

-10/35 can be reduced to -5/7

X = - 5/7

Hope this helps!

Problem number 26 of the Rhind Papyrus says: Find a quantity such that when it is added to StartFraction 1 Over 4 EndFraction of
STALIN [3.7K]

Answer:

The quantity is 12

Step-by-step explanation:

Here, we want to find the solution to the equation.

Let the quantity we are looking for be x;

According to the question;

The quantity plus a quarter of the quantity = 15

x + 1/4(x) = 15

x + x/4 = 15

Multiply through by 4

4x + (x/4)*4 = 15 * 4

4x + x = 60

5x = 60

x = 60/5

x = 12

Meg has a can that contains 80% of orange juice and the rest water. The can has 1 liter of water.
sammy [17]
<span>x is the total number of liters of orange juice and water combined. 80% of the mixture is pure orange juice which means 20% of it is water. Therefore, x 20/100 = 1 is the equation in single variable that can be used to find x. and 20/100 is 1/5 so there are 5 total liters in all and 5-1 is 4, so there are 4 liters of orange juice in the can. Hope this helps :)</span>

umka21 [38]

Answer:

Hence, 0.026 can be expressed as $2.6 \times 10^{-2}$.

Step-by-step explanation:

- Given 0.026

- Use given, move the decimal point so that first factor is greater than or equal to 1 but less than 10 .

- Then count n and write in scientific notation.

Step 1 of 1

Consider 0.026

$$\Rightarrow 2.6$$

Decimal has moved 2 places to right.

The power will be negative as original no. is less than 1 .

$$\begin{aligned}&2.6 \times 10^{-2} \\&0.026=2.6 \times 10^{-2} .\end{aligned}$$
