Answer:

$3\frac{3}5}$

Step-by-step explanation:

Divide using long division. The whole number portion will be the number of times the denominator of the original fraction divides evenly into the numerator of the original fraction, and the fraction portion of the mixed number will be the remainder of the original fraction division over the denominator of the original fraction.

Use the intersect method to solve the equation. x^2-7= -x^2+1

sineoko [7]

The intersect method would use the graphs of both equations to find points where they would cross each other. In this instance, the graphs would cross each other at two points: x = +/-2. (To solve this in the "traditional" form, add x^2 to both sides and then add 7 to both sides, leaving 2x^2 = 8, dividing 2 out to leave x^2 = 4. The square root of 4 = +/-2, as noted.)

Vladimir79 [104]

Answer:

x = 3.75

Step-by-step explanation:

ABC is a right angled triangle.

Therefore, by Pythagoras theorem:

${(10 - x)}^{2} = {x}^{2} + {5}^{2} \\ 100 - 20x + {x}^{2} = {x}^{2} + 25 \\ 100 - 20x = 25 \\ - 20x = 25 - 100 \\ - 20x = - 75 \\ x = \frac{ - 75}{ - 20} \\ \: \: \huge \red { \boxed{x = 3.75}}$
