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
Answer:
[tex]29\frac{3}{4}[/tex]
Step-by-step explanation:
The given expression is:
[tex]7 \frac{3}{4}+(-2 \frac{1}{5}) x[/tex]
The problem is asking to evaluate this expression with [tex]x=-10[/tex]
So, replacing this value, we have:
[tex]7\frac{3}{4}+(-2 \frac{1}{5}) (-10)\\\frac{31}{4}+\frac{11}{5}10\\\frac{31}{4}+\frac{110}{5}\\\frac{155+440}{20}\\ \frac{595}{20}=29.75=29\frac{3}{4}[/tex]
Therefore, the result is 29 [tex]\frac{3}{4}[/tex]
