Answer:
x < -1
Step-by-step explanation:
Solve -.4x-1.2 >.8 for x.
Start by adding 1.2 to both sides, to isolate -0.4 x:
-0.4x > 0.4
Divide both sides by -0.4, remembering the reverse the direction of the inequality sign:
x < -1
You're right, it is c because at most means less than or equal to. That's because if it's 'at most' you can still get it and prices less.
Explanation:
The formula for calculating the distance between two points is:
d=√(x2−x1)^2+(y2−y1)^2
Substituting the values from the points in the problem gives:
d=√(7−2)^2+(4−−6)^2
d=√(7−2)^2+(4+6)^2
d=√5^2+10^2
d=√25+100
d=√125
d=√25⋅5
d=√25√5
d=5√5
1 kg = 1000g
You can use proportion
1000 g ----- <span>£5.60
200g ------ x
x=(200 *5.60)/1000=5.60/5=1.12
Answer : 1.12 </span> £
