Required expression is,

$\frac{2\times 1\frac{1}{4}+\frac{5}{2}}{\frac{3}{4}}$

Approximately 7 cans are required.

Step-by-step explanation:

Given,

The number of cups required for lasagna recipe = $1\frac{1}{4}$

After doubling lasagna recipe, the number of cups required = $2\times 1\frac{1}{4}$

Also, the number of cups required for each pizza = $\frac{1}{2}$

If the number of pizza = 5,

Then the number of cups required for 5 pizza = $\frac{5}{2}$

So, the total cups required = $2\times 1\frac{1}{4}+\frac{5}{2}$

Hence, number of '3/4-cup cans' of tomato paste

$=\frac{\text{Total cups required}}{\frac{3}{4}}$

$=\frac{2\times 1\frac{1}{4}+\frac{5}{2}}{\frac{3}{4}}$

$=\frac{2\times \frac{5}{4}+\frac{5}{2}}{\frac{3}{4}}$

$=\frac{\frac{10}{4}+\fra{5}{2}}{\frac{3}{4}}$

$=\frac{\frac{10+10}{4}}{\frac{3}{4}}$

$=\frac{\frac{20}{4}}{\frac{3}{4}}$

$=\frac{20}{3}$

$=6.667\approx 7$

x = 47/4

Step-by-step explanation:

The acute angles of a right triangle are complementary, i.e. their sum is 90

So, 5x + 3x - 4 = 90

8x = 94

x = 94/8 = 47/4
