Answer:

A

Step-by-step explanation:

The equivalent expression of the complex fraction is [tex]\frac {2y - 4x}{5x + 3y}[/tex]

Equivalent expressions are expressions that have equal values, when compared

The expression is given as:

[tex](\frac 2x -\frac 4y) \div (\frac 5y + \frac 3x)[/tex]

Take LCM

[tex](\frac {2y - 4x}{xy}) \div (\frac {5x + 3y}{xy})[/tex]

Express the quotient as products

[tex](\frac {2y - 4x}{xy}) * (\frac {xy}{5x + 3y})[/tex]

Evaluate the product

[tex]\frac {2y - 4x}{5x + 3y}[/tex]

Hence, the equivalent expression of the complex fraction is [tex]\frac {2y - 4x}{5x + 3y}[/tex]

Answer: Approximately 20 miles per gallon

Step-by-step explanation:

The line of best fit is an approximate average. In order to predict the fuel efficiency you just estimate the place where x = 4800 and see what the y value of the line is for that point. In this case it's around 20 miles per gallon.

7. 136°

8. 44°

Step-by-step explanation:

i don't know english very well so i don't knoe what transplant is but i think i got it right with my logic

Answer:

m∠1 = 136°

m∠2 = 44°

m∠3 = 136°

m∠4 = 44°

m∠5 = 136°

m∠6 = 44°

m∠7 = 136°

Step-by-step explanation:

Corresponding angles, like m∠1 and m∠5, need to equal each other.

m∠1 and m∠3 are the same

m∠3 and m∠2 need to be added together to equal 180

Step-by-step explanation:

Answer:

X = 78, Z = 29, and Y = 102

Step-by-step explanation:

X = 78. 43 + 59 = 102. There has to be 180 degrees in a triangle. So subtract 180 by 102.

Z = 29. Think of the whole triangle for this one. 43 + 49 + 59 = 151. 180 - 151 = 29.

Y = 102. Plug in the value of Z. 49 + 29 = 78. 180 - 78 = 102.

Step-by-step explanation:

-3(x^2 - 10x + 16)  [Expand the equation using the FOIL method]

-3(x^2 - 10x) - 48  [Move the 16 outside of the parenthesis (16 * - 3 = -48]

-3(x^2 - 10x + 25) +75 - 48  [Complete the square]

-3(x-5)^2 + 27  [Simplify. The equation is now in vertex form.]

Answer: 20.8

Step-by-step explanation:

Since it is an equilateral triangle, we know the bottom is also 24. We also know that line E is bisecting the base. So using the smaller right triangle we know that the hypotenuse is 24 and one leg is 12. So use the Pythagorean theorem.

[tex]a^{2} +b^{2} =c^{2} \\12^{2} +b^{2} =24^{2} \\144+b^{2} =576\\b^{2} = 432\\b= 20.8[/tex]

Answer:

The smallest number of kilometers that each must have ran is 6 km

Step-by-step explanation:

The distance Jasper prefers to run at a time = 6 km

The distance Emma prefers to run at a time = 3 km

The distance ran by Jasper at month end = The distance ran by Emma at the end of the month

The smallest number of kilometers that each must have ran is given by the lowest common multiple, LCM of 6 and 3 as follows;

The multiples of 6 are;

6 × 1 = 6, 6 × 2 = 12...

The multiples of 2 are;

3 × 1 = 3, 3 × 2 = 6...

∴ The LCM of which = 6

Therefore, the smallest number of kilometers that each must have ran = 6 km
