(a) Form expressions using $ t $ and 4 . Use not more than one number operation. Every expression must have $ t $ in it.
(b) Form expressions using $ y, 2 $ and 7. Every expression must have $ y $ in it. Use only two number operations. These should be different.
To do:
We have to form expressions using the given details.
Solutions:
(a) $(t + 4), (t - 4), 4t, (4 - t), (4 + t), (\frac{t}{4}), (\frac{4}{t})$ are the expressions using $t$ and $4$.
(b) $2y + 7, 2y - 7, 7y + 2, 7y-2$ are few expressions using $y, 2$ and $7$
