Evaluate and simplify the expression when a = 4 and b = -1.

Gwar [14]

Answer:

$\frac{3}{2}$

Step-by-step explanation:

$\frac{5 - 2(a + 3b)}{2}$

substitute a = 4 and b = -1

$= \frac{5 - 2(4 + 3( - 1))}{2}$

expand and simplify the numerator

$= \frac{5 - 2(4 - 3)}{2}$

$= \frac{5 - 2(1)}{2}$

$= \frac{5 - 2}{2}$

$= \frac{3}{2}$

The pyrotechnic team for Fist Bump’s tour want to know how high the arena is to 2 decimal places. The arena is 61.3786 metres hi

Aloiza [94]

When you find any value to x amount of decimal places, you need to go to the term AFTER that to determine the correct value. So, for this, take 61.378 metres. From here, look if the last number is 4 or less. If the number is 4 or less, take the leftmost number off, and you will have your answer (if we had 61.373, the correct answer would be 61.37). If the number is 5 or more, take the leftmost number off, and add 1 to the new leftmost number. Since the last number is 8, the correct answer here is 61.38 metres high. If adding 1 makes the number 10, keep the 0 at the end. So, if you had 61.399, you would make it 61.40
