2zx2y=18 where x=1,z=y

Bad White [126]

$\huge \bf༆ Answer ༄$

Let's plug the given values and find value of y ~

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:2zx2y = 18$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:2 \times y \times 1 \times 2 \times y = 18$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:4 {y}^{2} = 18$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:{y}^{2} = \dfrac{18}{4}$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:y {}^{2} = 4.5$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:y = \sqrt{4.5}$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:y = \sqrt{9 \times 0.5}$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:y = 3 \sqrt{ \frac{5}{10} }$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:3 \sqrt{ \frac{1}{2} }$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \: \dfrac{3}{ \sqrt{2} }$

or, you can further simplify it to ;

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:2.12 \: \: (upto \: \: two \: decimals)$

after 12 girls left the school assembly the ratio of the number of boys to girls is 3 to 4. if there were w boys at the assembly

son4ous [18]

Let g = original # of girls at the assembly.
Let w = # of boys at the assembly.

Equation of ratios:

w 3 boys
------- = ---- = --------------------------------------------
g-12 4 girls after 12 have left assembly
4w + 36
Cross-mult., 4w = 3g - 36, so 4w + 36 = 3g, and g = --------------- (answer)
4

This is "original # of girls at the assembly in terms of w, the # of boys at the assembly."

Eva8 [605]

Answer: x = 400 MPH x+60 = 460 MPH

Step-by-step explanation:

(Distance = (Rate)(Time)

Let x = speed of the LA bound plane

Then, x+60 = speed of NYC bound plane

Sum of distances = 2464

3.4x + 2.4(x+60) = 2464

5.8x + 144 = 2464

5.8x = 2320

x = 400 MPH x+60 = 460 MPH
