hoa [83]

Remark

The thing you must not do is write 7.182 as your answer. That is the exact answer found using a calculator.

What to do.

What you should do is multiply two rounded numbers together.

7.6 rounded is 8 roughly

0.945 is almost 1.

Your answer is 8*1 = 8 roughly. This skill is very handy when you are writing a test and you want to see if you've done the question correctly. It is easy to misplace a decimal or put in incorrect digits and this is a quick check on things like that.

Solve 2y = 6x + 10 y = 2x + 4

mihalych1998 [28]

Answer:

x =-1

Step-by-step explanation:

$\left \{ {{2y = 6x +10} \atop {y = 2x +4}} \right.$

replace y by 2x +4 in the first equation

2(2x + 4) = 6x + 10

4x + 8 = 6x + 10

-2x +8 = 10

-2x = 2

x = -1
