Answer:
6
Step-by-step explanation:
First you solve the brackets;
68+7 = 75
Then you add the 93;
75+93 = 168
Multiplying decimals:
First, multiply like a normal number.
64 × 37 = 2368
Add up the number of decimal points from your original numbers to find out where you should put the decimal point on your result.
6.4 has one decimal place, and -3.7 has one decimal place.
Our result should have two decimal places. (1+1)
23.68
Because we multiplied by a negative number, our result should be negative, too.
-23.68
We would have to convert 3/4 to a decimal of 0.75 (the equivalent)
0.75*23 = 17.3
-or-
3 * 23 = 69
4 * 23 = 92
Answer:
k=13
Step-by-step explanation:
3k+6+4k-7+90=180
7k+89=180
k=180-89/7
k=13
