Given the proportion x/y = 2/5, what ratio completes the equivalent proportion: x/2= ?/?

prohojiy [21]

Cross multiply the original proportion

5x = 2y Divide by 2
5x/2 = y Now divide by 5
x/2 = y/ 5

So the answer is y/5

3(x+1)^(4/3)=48<br><br> how do i solve this?

IrinaK [193]

$3(x+1)^{\frac{4}{3}}=48\\\\\frac{3(x+1)^{\frac{4}{3}}}{3}=\frac{48}{3}\\\\(x+1)^{\frac{4}{3}}=(x+1)^{(\frac{1}{3}*4)}=\sqrt[3]{(x+1)^{4}}=16\\\\(\sqrt[3]{(x+1)^{4}})^{3}=16^{3}\\\\(x+1)^4=4096\\\\\sqrt[4]{(x+1)^4}=\sqrt[4]{4096}=\pm8\\\\\\x+1=\pm8\\\\x+1=8\\x=7\\\\x+1=-8\\x=-9$

Your answers are x = 7 and x = -9.

△ABC is the image of △XYZ after a sequence of rigid transformations.

Korvikt [17]

Answer:

D. ∠B≅∠Y, ∠A≅∠X, ∠C≅∠Z

Step-by-step explanation:

Corresponding angles are in the same order in both triangle names. That is, the corresponding angles are ...

(A, X), (B, Y), (C, Z)

Rigid transformations do not change any angles, so the angles of the image are the same as the corresponding angles of the original.

∠A≅∠X, ∠B≅∠Y, ∠C≅∠Z . . . . . matches selection D
