Step-by-step explanation:
a) i) original cuboid = 3×5×2 = 30 cm³......(i)
ii) ratio : 3×2 = 6cm (width), 5×2 = 10 cm (length),
2×2 = 4 cm (height).
enlarged cuboid = 6×10×4 = 240 cm³....(ii)
b) ratio = 240cm³/30cm³ = 8:1.
hope this helps you.
E. none of the above because there the opposite because one is division and the other is multiplication hope it helps
Doing (2x-5) first is what
0.5 to the fourth power equals 0.0625.
7x - xy = -18 x = -4
First, fill the -4 in where the "x's" are.
7<u>(-4)</u> - <u>(-4)</u>y = -18
Then, add the 28 over.
-28 + 4y = -18
<u>+28</u> <u>+28
</u>4y = 10
Then, get the variable by itself, so you would divide the 4 over.
4y = 10
<u>÷4</u> <u>÷4
</u>
<em><u>y = 2.5</u></em>
