You have $3.70 in dimes and quarters. You have 5 more

Mathematics

anygoal [31]2 years ago

Answer:

Step-by-step explanation:

10x + 25y = 370

y = x + 5

10x+25(x+5)=370

10x+25x+125=370

35x=370-125

x=245/35

x=7 which is the number of dimes

x+7= 7+5= 12 which is the number of quarters

So you have 12 quarters. That means you have 7 dimes.

Use the pattern below for questions 6 - 8.
Yuliya22 [10]

Answer:

See below

Step-by-step explanation:

<u>The sequence given</u>

  • 6, 19, 58, 175

<u>We see the pattern: triple the previous term plus 1</u>

  • 2) 19 = 6*3 + 1
  • 3) 58 = 19*3 + 1
  • 4) 175 = 58*3 + 1

<u>Next two terms</u>

  • 5) 175*3 + 1 = 526
  • 6) 526*3 + 1 = 1579

<u>Following two terms</u>

  • 7) 1579*3 + 1 = 4738
  • 8) 4738*3 + 1 = 14215

Answer:

a) h = -\frac{7}{4}, b)  h = f\,\circ\,g (-5) = \frac{3}{2}, c) h = g\,\circ\,f (-2) = \frac{3}{8}

Step-by-step explanation:

We proceed to solve each exercise below:

a) f(-2) +3\cdot g(0)

h = \frac{2\cdot (-2)}{3\cdot (-2)+5}+3\cdot \left(\frac{3}{0+4} \right)

h = \frac{-4}{-6+5} +3\cdot \left(\frac{3}{4} \right)

h = -4+\frac{9}{4}

h = \frac{-16+9}{4}

h = -\frac{7}{4}

b) h = f\,\circ \,g (-5)

h = f\,\circ\,g (x)  = \frac{\frac{6}{x+4} }{\frac{9}{x+4}+5 }

h = f\,\circ\,g (x)= \frac{\frac{6}{x+4} }{\frac{9+5\cdot (x+4)}{x+4} }

h = f\,\circ\,g (x) = \frac{6}{29+5\cdot x}

h = f\,\circ\,g (-5) = \frac{6}{29+5\cdot (-5)}

h = f\,\circ\,g (-5) = \frac{3}{2}

c) h = g\,\circ\,f(-2)

h = g\,\circ \, f (x) = \frac{3}{\frac{2\cdot x}{3\cdot x + 5} + 4  }

h = g\,\circ\,f (x) = \frac{3}{\frac{2\cdot x +4\cdot (3\cdot x +5)}{3\cdot x +5 } }

h = g\,\circ \,f (x) = \frac{3\cdot (3\cdot x +5)}{2\cdot x +12\cdot x +20}

h = g\,\circ\,f(x) = \frac{9\cdot x +15}{14\cdot x +20}

h = g\,\circ\,f(-2) = \frac{9\cdot (-2)+15}{14\cdot (-2)+20}

h = g\,\circ\,f (-2) = \frac{-3}{-8}

h = g\,\circ\,f (-2) = \frac{3}{8}
