The ratio x + y : x - y is equal to 2 : 1.<br> Write an equation for x in terms of y.
Dvinal [7]

Answer:

x=3y

Step-by-step explanation:

ATQ

(x+y):(x-y)=2

or, x+y=2x-2y (crossmultiply)

or, 0= 2x-x-2y-y

or, x- 3y=0

or, x=3y is required equation

How do you identify quadratic equations?
alisha [4.7K]
Often the easiest method of solving a quadratic equation is by factoring. Factoring means finding expressions that can be multiplied together to give the expression on one side of the equation. ... The equation x2+x−6=0 x 2 + x − 6 = 0 is in standard form.

What’s the answer to this and working out
fiasKO [112]

Answer:   \bold{\dfrac{81}{4t^2u^{20}}}

<u>Step-by-step explanation:</u>

\bigg[\dfrac{4\cdot t^{-1}\cdot u^6}{18\cdot t^{-2}\cdot u^{-4}}\bigg]^{-2}\\\\\\\text{simplify 4 and 18 by dividing each by 2:}\\\bigg[\dfrac{2\cdot t^{-1}\cdot u^6}{9\cdot t^{-2}\cdot u^{-4}}\bigg]^{-2}\\\\\text{distribute the exponent using the power rule (multiply the exponents):}\\\dfrac{2^{-2}\cdot t^{2}\cdot u^{-12}}{9^{-2}\cdot t^{4}\cdot u^{8}}

\text{Move the terms with negative exponents to the other side of the fraction}\\\text{bar and change the sign of the exponents:}\\\dfrac{9^2\cdot t^2}{2^2\cdot t^4\cdot u^8\cdot u^{12}}\\\\\\\text{Simplify using the multiplication rule for exponents (add the exponents)}\\\text{and the division rule of exponents (subtract the exponents):}\\\dfrac{81}{4\cdot t^{4-2}\cdot u^{8+12}}\\\\\\\text{Simplify:}\quad \dfrac{81}{4\cdot t^{2}\cdot u^{20}}

What statement is true about the angles in triangle PQR
DENIUS [597]

Answer:

(C) The sum of the measures of ∠P, ∠Q, and ∠R is 180°

Step-by-step explanation:

All triangles, when their three angles are added up, gets us 180°.

This goes without saying, even with scalene triangles.

Additionally, the angles in squares add up to 360°, the angles in a pentagon add up to 540°.

Hope this helped!
