Mario eats twice as many as Yolanda. If Yolanda eats 6 walnuts every day, how many walnuts does Mario eat in a week?

stepladder [879]

let

x-------> walnuts that Mario eats in a week

y-------> walnuts that Yolanda eats in a week

we know that

x=2y-------> equation 1

y=6*7-------> y=42 walnuts

substitute the value of y in equation 1

so

x=2*42-----> x=84 walnuts

therefore

the answer is

Mario eat in a week 84 walnuts

Write the equation in slope intercept form. Then find the slope and y intercept of the line. Y=-5

lisov135 [29]

$\bf y=\stackrel{slope}{m}x+\stackrel{y-intercept}{b}
\\\\\\
y=-5\implies y=0x-5\implies y=\stackrel{slope}{0}x\stackrel{y-intercept}{-5}$

Solve <br> 2z = modulus of z + 2i

Marta_Voda [28]

I assume the equation is

$2z=|z|+2i$

then let $z=x+iy$ .

$2x+2iy=\sqrt{x^2+y^2}+2i$

$2x+2i(y-1)=\sqrt{x^2+y^2}$

The right side is real-valued and positive, and only on the left side do we have an imaginary term, which tells us

$2(y-1)=0\implies y=1$

Then

$2x=\sqrt{x^2+1}$

$4x^2=x^2+1$

$3x^2=1$

$x=\pm\dfrac1{\sqrt3}$

but again we omit the negative solution, so that

$\boxed{z=\dfrac1{\sqrt3}+i}$

Can someone pls help me <br> Solve for x <br> Please show ur work

Kitty [74]

Answer:

9=x

Step-by-step explanation:

80º=(8x+8)º

80=8x+8

Subtract 8 from both sides of the equation.

72=8x

Divide 8 from both sides of the equation.

9=x

Hope this helps :)
