m∠C = (1/2)(m arc AB), because ∠C is an inscribed angle.

(5x-7) = (1/2)(2x)

5x-7 =x

4x = 7

x= 7/4 or 1.75

Sergio [31]

Answer:

3 loaves of bread

Step-by-step explanation:

We must divide $2\frac12$ by $\frac34$ and take an integer part of this dividing.

$2\frac12:\frac34=\frac52:\frac34=\frac52\cdot\frac43=\frac{20}{6}=\frac{10}3=3\frac13$

The integer part of a mixed fraction $3\frac13$ is 3, and this is the answer.

10. What makes an equation a quadratic?

CaHeK987 [17]

Answer:

D. The equation has a variable multiplied by itself. A squared variable.

Step-by-step explanation:

A quadratic equation will always start with a term being squared. For example, $8x^{2}$ + 5x + 7 = 44. Another example would be $4x^{2}$ + 2x - 10 = 12. These are just random numbers, but the equation will always look the same! Hope this helps!
