Mathematics
1 answer:
Makovka662 [10]3 years ago
4 0

Answer:

\bold{x=2}

Step By Step Explanation:

Expand \bold{2.5\left(6x-4\right): \ 15x-10}

Expand \bold{10+4\left(1.5+0.5x\right): \ 2x+16}

\bold{15x-10=2x+16}

Add 10 To Both Sides

\bold{15x-10+10=2x+16+10}

Simplify

\bold{15x=2x+26}

Subtract 2x From Both Sides

\bold{15x-2x=2x+26-2x}

Simplify

\bold{13x=26}

Divide Both Sides By 13

\bold{\frac{13x}{13}=\frac{26}{13}}

Simplify

\bold{x=2}

k0ka [10]
2/3 = 0.66

1 hour = 60

60 x 0.66 = 39.6 or 40

60 - 40 = 20

He would drink 3 1/2 liters every 30 minutes.

He drinks 3 1/2 every hour.

liq [111]
v=\frac{d}{t}\\\\v-velocity;\ d-distance;\ t-time\\-------------------------\\v=\frac{d}{t}\ \ \ \ |multiply\ both\ sides\ by\ t\\vt=d\ \ \ \ |divide\ both\ sides\ by\ v\\\\t=\frac{d}{v}\\------------------------

v=45\ mph;\ d=240\ mi\\\\t=\frac{240}{45}=\frac{240:15}{45:15}=\frac{16}{3}\ (h)\\\\1h=60min\\\\therefore\\\\t=\frac{16}{3}\cdot60min=16\cdot20min=\boxed{320min}

Determine whether or not the two equations below have the same solution. In two or more complete sentences, explain your rationa
andrew-mc [135]

Answer:

Both equations have the same solutions.

Step-by-step explanation:

Please consider the complete question:

Determine whether or not the two equations below have the same solution. In two or more complete sentences, explain your rationale.

\frac{2}{3}x+\frac{3}{4}=8...(1)

8x=87...(2)

Let us solve our 1st equation as:

\frac{2}{3}x\cdot 12+\frac{3}{4}\cdot 12=8\cdot 12

2x\cdot 4+3\cdot 3=96

8x+9=96

8x+9-9=96-9

8x=87

Now, we can see that equation (1) turns out same as equation (2), therefore, both equations will have the same solution.
