The answer is
q + d = 12
0.25q + 0.10d = 2.40
q - the number of quarters
d - the number of dimes
You have 12 <span>coins, all quarters and dimes:
q + d = 12
The value of 1 quarter is $0.25.
The value of 1 dime is $0.10.
Therefore, if you want to pay </span>$2.40 you will have q quarters of value $0.25(0.25q) and d dimes of value $0.10d (0.10d).
The second equation is:
0.25q + 0.10d = 2.40
(-3/8)(+8/15)
Answer will be a negative number. Whenever multiplying a - negative number * a + positive = - negative number.
(-3/8)(+8/15)
Cross out -3 and 15 . Divide by 3. -3/3,=-1 15/3
= -1/5
Cross out 8 and 8. Divide by 8.
8/8= 1 , 8/8= 1
-1/5*1/1= -1/5
Answer : -1/5
Answer:
The solutions are y=0, -5/2
Step-by-step explanation:
-3y(2y+5)=0
We can use the zero product property
-3y =0 2y+5 =0
y =0 2y = -5
y = -5/2
The solutions are y=0, -5/2
The answer is A.y32 because you need to multiple
In the given question, the options are related to linear pair .
And according to linear pair, if a line cuts another line at a point, then the sum of the adjacent angles formed at that point is 180 degree.
Therefore, from the given diagram we can say that, angles WXY and YXZ are linear pair, so there sum have to be 180.
And the correct option is the third option .
