Answer:

\frac{6}{5} or 1\frac{1}{5}

Step-by-step explanation:

\frac{2}{5} *3

3 can be rewritten as 3/1

=\frac{2}{5}*\frac{3}{1}

Multiply the numerators and denominators

2*3=6\\5*1=5

= \frac{6}{5}

You can also change this into a mixed number by dividing the numerator by the denominator and writing the remainder as the numerator:

= 1\frac{1}{5}

I hope this helps!

Dylan has a bank that sorts coins as they are dropped into it. A panel on the front displays the total number of coins inside as
vesna_86 [32]

Answer:

1). System of equations- D + Q = 90 and D + 2.5Q = 175.50

2). There are 33 dimes and 57 quarters in the bank.

Step-by-step explanation:

Dylan has a bank that sorts coins as they are dropped in it.

A panel shows the total number of coins inside as well as the total value of these coins.

Let the number of dimes in the bank = D

and the number of quarters in the bank = Q

If the panel shows total number of coins = 90

Then the equation will be

D + Q = 90 -------(1)

And the panel displays the amount of the coins = $17.55

Then equation will be

0.10D + 0.25Q = 17.55 [1 Dime = $0.10 and 1 quarter = $0.25]

D + 2.5Q = 175.50 ------------(2)

Now we subtract equation (1) form equation (2)

D + 2.5Q - (D + Q) = 175.50 - 90

D + 2.5Q - D - Q = 85.5

1.5Q = 85.5

Q = \frac{85.5}{1.5}

   = 57

By putting Q = 57 in the equation (1)

D + 57 = 90

D = 90 - 57 = 33

Therefore, there are 33 dimes and 57 quarters in the bank.

Estimate the sum for 1,537 times 242 then find the sum
Furkat [3]
It says to estimate first 1,537 turns to 2,000 because the 5 is 5 or more so the 1 becomes 2 and everything else is zeros. Now multiply 2000x 242=484,000 is the Estimation. Now find the correct product for 1,537x242=371,954

nicole and adam are each saving money for a car. the total amount of money nicole will save is represented by the function f(x)=
Natalija [7]
They will have the same amount of money after 7 weeks.

We first set these equal to each other:
36+4x=x²+15

We want to gather all of the variables on one side.  Subtract 4x from both sides:
36+4x-4x=x²+15-4x
36=x²-4x+15

We want the equation to be equal to 0 to solve it, so subtract 36 from both sides:
36-36=x²-4x+15-36
0=x²-4x-21

We can factor this expression.  We want factors of -21 that sum to -4; -7(3)=-21 and -7+3=-4:
0=(x-7)(x+3)

Using the zero product property, we know that x-7=0 or x+3=0; this means x=7 or x=-3.  Since a negative number of weeks makes no sense, the answer is 7 weeks.
