Answer:
1. Simplify the inequality 5.1(3 + 2.2x) > -14.25 - 6(1.7x + 4):
15.3+11.22x>-14.25-10.2x-24 10;15.3+11.22x>-10.2x-38.75.
2. Separate terms with x and without x in different sides:
11.22x+10.2x>-38.75-15.3.
3. Add similar terms:
21.42x>-54.05.
4. Divide by 21.42:
x>-54.05/21.42
x>-2.5
Step-by-step explanation:
Let the two number be x and y.
x+y=-1......i
2x+4y=-10.....ii
solving the simultaneous equation we have:
from equation i, making x the subject we get:
x=-1-y........iii
substituting iii in ii we get:
2(-1-y)+4y=-10
-2-2y+4y=-10
2y=-10+2
2y=-8
y=-8/2=-4
substituting the value of y in iii we get:
x=-1-(-4)
x=-1+4
x=3
therefore the first number is 3 and the second number is -4
Pretty sure it’s 81
