Answer:
- 689·1910 = 1315990
- because the numbers are whole numbers
Step-by-step explanation:
Rounding a whole number to the nearest whole number does not change its value. If the estimate is to use numbers rounded like that, it must be the actual product when the numbers are whole numbers.
689·1910 = 1315990
Answer:
the numbers are -5 and 3
Step-by-step explanation:
First of all, the question is asking you to find the values of x from the given inequalities.
-8x -19<21 and 3x - 4 < 5
group all liked terms, in other words, make x and its coefficient stand alone.
-8x < 21 + 19 and 3x < 5 + 4
-19 became +19 because it crossed the sign <, also -4 became +4 because it crossed the sign <.
so we get
-8x < 40 and 3x < 9
we divide each "x" by its coefficient

then we get
x < -5 and x < 3
but x is positive so it's greater than -5 so we get
x > -5 and x < 3
