Answer:

x = 0

Step-by-step explanation:

This is saying that 2(13x) < 15

If you have 2[13(0)] < 15

It will come to 2(0) < 15

This equals 0 < 15 which is true therefore making the <u>x</u> value = <u>0</u>

You begin with $25 in a savings account and $50 in your checking account. Each week you deposit $5 into savings and $10 into che
Phantasy [73]

Answer:

The amount in checking will always be twice in any week.

Step-by-step explanation:

Let's say, w represents the week, s represents the saving account and c represents the checking account.

Balance in saving account in any week =s=5w+25

Balance in checking account in any week  =c=10w+50

Translate the statement into mathematical equation. Remember to use " = " for word "is" in the given statement.

We have to find w for 2s = c.

Putting the values, we have:

2(5w+25)=10w+50

\Rightarrow \mathrm{True\:for\:all}\:w

Which means in each week the amount in checking is twice the amount in savings.

Best Regards!

Solve for x round to the nearest tenth
lidiya [134]

Answer:

47.0

Step-by-step explanation:

In this right angle triangle, we are faced with a challenge of two sides. The opposite side and the adjacent side, hence the tangent is used.

Where it is the opposite side and hypothenus side, the sine is used and when it is the hypothenus side and adjacent side, the cosine is used.

Hence, we have tan62°=x/25

We cross multiply, to have

25(tan 62°)= x

x = 47.01816

In rounding up numbers, number 1 to 4 will be rounded up to zero, while numbers 5 to 9 will be rounded up to 1.

Rounding up 47.01816 to the nearest tenth. The tenth value is the figure is 0, before it we have 1, which is to hundredth. 1 will be rounded up to zero.

So we have 47.0
