Parker has 23 dimes and 19 quarters.

Answer:

No. of quarters=19

No. of dimes = 23

Step-by-step explanation:

1 quarter is  25  cents  and  1  dime is  10  cents .

Let the number of quarters  =  x. Then, the number of dimes  =  x + 4 . So

( x ⋅ 25 ) + ( x+ 4 )⋅ 10 = $ 7.05 = 705 cents.  25 x + 10 x + 40 = 705   35 x = 665  x =  665  

35 =  19

Parker has  19  quarters and  19 + 4 = 23  dimes in all.

Which expression has a positive value?
Black_prince [1.1K]

Answer:

3 (negative 64 divided by 8) + 25 = 1

Step-by-step explanation:

Negative 4 + (negative 5) (negative 6) divided by (negative 3) = -4 + (-5)(-6)/(-3) = -4 + 30/-3 = -4 - 10 = -14

8 Left-bracket 10 divided by (2) (negative 2) Right-bracket = 8(10/((2)(-2)) = -20

3 (negative 64 divided by 8) + 25 = 3(-64/8) + 25 = 3(-8) + 25 = -24 + 25 = 1

Negative 2 (negative 5) (negative 3) divided by 10 = (-2)(-5)(-3)/10 = -3

The only positive value here is 1, which is a result of 3 (negative 64 divided by 8) + 25

First number is a and second one is 2a+4
a(2a+4)=48
a(a+2)=24
a^2+2a-24=0
(a+6)(a-4)=0
the question says a is negative so a=-6 b=-8
