I think its 18.24 because if you multiply it by 3.14 then subtract u should get 18.24
x ≤ 2.6 would look like this on the number line, the 2.6 part would be shaded in as well and not left open since x is less than OR EQUAL to 2.6
1.
The edge lengths of a triangle are inversely proportional to 2,3 and 4.
The actual proportions of the lengths are then
12(1/2:1/3:1/4)=6:4:3
The longest side
= 39* (6/(6+4+3)
= 39*6/13
=18
2. 63 breads : 35 kg flour
is the same as
54 breads : x kg flour
Cross multiply and get
x=54*35/63=30
30 kg of flour are needed to make 54 breads.
Answer:
true.
Step-by-step explanation:
Let number of miles be x
<span>when is </span>
<span>.5x + 25 = .25x + 30 </span>
<span>times 4 </span>
<span>2x + 100 = x + 120 </span>
<span>x = 20 </span>
