16 divided by 125 is .128
125 plus 75 is 200
.128 multiplied by 200 is 25.6 days
Answer:
-4x=4
Step-by-step explanation:
-4x+7=11 subtract 7 add to the 11 answer-4x=4
Your answer for rounding 2.8497 x 10^3 is correct: 2.85 x 10^3.
350.0 is not correct because it has 4 sig figs. The proper rounding would be simply 350. with not additional zeros.
Answer:
Step-by-step explanation:
Corresponding angles of two parallel lines are always equal. The angle on "top" of 
corresponds with the angle marked as 
. Therefore, its measure must also be .
Since these two angles form one side of a line which has 180 degrees, we have the following equation:
Combine like terms:
Subtract 15 from both sides:
Divide both sides by 3:
If a solution(s) exists y=y so we can say:
x^2-3x=-2x+2 add 2x to both sides
x^2-x=2 subtract 2 from both sides
x^2-x-2=0 factor
(x-2)(x+1)=0
So x=-1 and 2, using y=-2x+2 we find:
y(-1)=4 and y(2)=-2
So the two solutions occur at the points:
(-1,4) and (2,-2)
