0.46/1 , 46/100 (both are simple to calculate/find) but theres lots of other fractions, which will not be "simpler" to find
do you not know how to convert a decimal to a fraction?
Answer:
x=3cm
Step-by-step explanation:
We have three figures.A triangle(8 by X+3).In it we have another triangle(4 by x)and a trapesium
thus that means the area of the trapesium+area of small triangle=area of big triangle.
1)Area=1/2lengthxwidth. =1/2×8×(x+3)
=4(x+3)
=4x+12cm³
2)Area=1/2lengthxwidth. =1/2×4×x
=2x
3)area=1/2(a+b)h
=1/2(x+3+x)×4
=1/2×4(2x+3). (area of trapesium)
=2(2x+3)
=4x+6cm³
thus:
2x+4x+6=4x+12 put like terms together
2x+4x-4x=12-6
2x=6 divide both sides by 2
x=3cm
Answer:
62; 68
Step-by-step explanation:
<u>Micah</u>
12 + (10 x 5) = 62
<u>Lucy</u>
8 + (12 x 5) = 68
Answer:
im pretty sure its equal to
Step-by-step explanation:
9 and 1/12 inches of pipe remain because
30 and 3/4 = 30 and 9/12
4 and 1/3 = 4 and 4/12
4 and 4/12 x 5 = 20 and 20/12
which can be simplified to 21 and 8/12
30 and 9/12 - 21 and 8/12 = 9 and 1/12.
