Answer 1

Ответ:

x = 7,5

Пошаговое объяснение:

5/7 ×10,5 =x

5/7 ×21/2 =x

x=15/2

x= 7. 1/2 , x= 7,5

Answer 2

It seems like you're trying to set up a proportion and solve for the missing value $x$. To solve this proportion, you can cross-multiply and then solve for $x$.

The given proportion is:

$$\frac{15}{1.4} = \frac{x}{0.7}$$

Cross-multiplying, you get:

$$15 \times 0.7 = 1.4 \times x$$

Simplifying:

$$10.5 = 1.4x$$

Now, divide both sides by 1.4 to solve for $x$:

$$x = \frac{10.5}{1.4} = 7.5$$

Therefore, the value of $x$ that satisfies the given proportion is $x = 7.5$.
