4x - 3(x + 5) > 7 - 4(x + 6) |use distributive property; a(b + c) = ab + ac
4x - 3x - 15 > 7 - 4x - 24 |combine items
x - 15 > -4x - 17 |add 15 to both sides
x > -4x - 2 |add 4x to both sides
5x > -2 |divide both sides by 5
x > - 2/5
The answer would be 0.95 totaling 1 as there is only 1 chance that this will happen
Answer:
0.43
Step-by-step explanation:
Answer:
temperature of city a=5
temperature of city b=4
Step-by-step explanation:
Given:
Let temperature of city A= a
temperature of city B=b
As given:
4a=8+3b
a-2b=-3
rearranging 2nd equation we get:
a=-3+2b
substituting above in 1st equation we get:
4(-3+2b)-3b=8
8b - 12 = 3b + 8
8b-3b=12+8
5b = 20
b = 4
Now substituting b=4 in 4a = 8 + 3b
, we get
4a = 8 + 3b
4a = 8 + 3(4)
4a = 8 + 12
4a = 20
a = 20/4
a = 5
temperature of city a and city b on that day is 5C and 4C respectively!
