Evalulate 7 3/4+(-2 1/5) x for x =-10

Mathematics
1 answer:
maksim [4K]3 years ago
6 0

Answer:

2884

Step-by-step explanation:

First plug in -10 for x, which would look like this: 734 + (-215 * (-10) ) =

Then, first you calculate everything in the parenthesis, which is (-215) * (-10)

and the equation would look like this after you multiply: 734 + 2150 =

If you noticed the number turned out positive after we multiplied, that is because - number times a - number would always be positive, just like if you divide - number by a - number your answer would be positive.

Your last step would be adding 734 with 2150. : 734 + 2150 = 2884

+ 734

2150

_____

2884

And the answer would be 2884

Simplify: 70x/2x.<br> A. 32<br> B. 33<br> C. 34<br> D. 35
Tresset [83]
The answer is D. 35. The x’s cancel out because x divided by x is 1 leaving you with 70/2 which is then 35.
Hope this helped.
