A collection of nickels and quarters is worth 2.85 . There are 3 more nickels than quarters how many nickels and quarters are th
Zolol [24]

A nickel is equal to 5 cents or 0.05 dollars.

A quarter is equal to 25 cents or 0.25 dollars.

Let number of nickels be = n

Let number of quarters be = q

0.05n+0.25q=2.85    ...........(1)

As it is given, there are 3 more nickels than quarters so equation becomes,

n=q+3   ................(2)

Plug in the value of 'n' from (2) in (1)

0.05(q+3)+0.25q=2.85

= 0.05q+0.15+0.25q=2.85

0.30q=2.70

q=9

As n=q+3 we get, n=9+3=12

Hence, there are 12 nickels and 9 quarters.

In the figure, △ABC is similar to △DEF. what is m∠1
Nady [450]

Answer:

C. 139°

Step-by-step explanation:

Given:

m<A = 62°

m<B = 77°

Required:

Find m<1

Solution:

Since ∆ABC is similar to ∆DEF, therefore:

<A ≅ <D, which means m<D = 62°

<B ≅ <E, which means m<E = 77°

<C ≅ <F

Therefore, based on exterior angle theorem:

m<1 = m<D + m<E

m<1 = 62° + 77° (substitution)

m<1 = 139°

I need to know how to simplify this equation
ArbitrLikvidat [17]

\frac{ {3}^{x + 4} -  {3}^{2x + 2}  }{ {3}^{x - 2} \times  {3}^{x + 4}  }  =   \frac{x + 4 - 2x - 2}{(x - 2) \times (x + 4)}  =  \frac{ - x + 2}{ {x}^{2} + 4x - 2x - 8 }  =  \frac{ - x + 2}{ {x}^{2}  + 2x - 8}
