PLEASE HELP ASAP!!!! m = 10 - 6 / 7 – 8.5

Mathematics
1 answer:
gtnhenbr [62]3 years ago
5 0

For this case we have to define the order of algebraic operations, that the division and multiplication must be done before (from left to right) that the addition and subtraction.

Then, given the following expression:

m = 10-6÷7-8.5

We have to:

\frac {6} {7} = 0.857

So, we have:

m = 10-0.857-8.5

We must bear in mind that equal signs are added and the same sign is placed, while different signs are subtracted and the sign of the major is placed.

m = 10-9,357\\m = 0.643

Answer:

m = 0.643

Pls can I have help with this question if you know it pls tell me ☝
Andrew [12]
Yearly compound interest is given by the following formula:

A = P(1+r)^t

A is the total amount after the time period elapses. P is the initial amount invested. r is the interest rate in decimal form, and t is the amount of years that elapse.

The interest rate is 1.5%. Divide by 100 to convert into a decimal:

1.5 \div 100 = 0.015

We now have all of our values to plug into the equation:

P = 12,000, r = 0.015, t = 2
12,000(1+0.015)^{2}
12,000(1.015)^{2} = 12,362.7

After 2 years, Mary will have 12,362.70 euros in her account.

To find the value of the investment, subtract the original amount from the new amount:

12,362.70 - 12,000 = 362.70

The value of the investment is £362.70.

How to solve equation an equation without y using elimination method
Sedbober [7]

Work only with the second equation at the beginning. Solve for x for it.

7x - 2x = 3                Combine the left hand side.

5x = 3                       Divide by 5

5x/5 = 3/5                Do the division

x = 3/5 = 0.6    

==============

Now work with the top equation.

3(0.6) + 5y = 13              Multiply on the left.

1.8 + 5y = 13                   Subtract 1.8 from both sides.

1.8 - 1.8 + 5y = 13 - 1.8    Do the subtraction

5y = 11.2                          Divide by 5

5y/5 = 11.2/5

y = 2.24                           Answer

Write an equation to convert a diamond's weight in carats to its weight in milligrams. Be sure to define your variables.
kolbaska11 [484]
Carats, known as ct, is a measure of weight used for gemstones.One carat is equal to 1/5 of a gram (200 milligrams). Stones are measured to the nearest hundredth of a carat. So, the equation would be as follows:

m = c x 200

where m is the mass in units of milligrams and c is the weight in units of carats.

Hope this helped. Have a nice day.
