Answer:
3 dimes and 10 quarters
Step-by-step explanation:
If you add 7 dimes, then the number of dimes and quarters is the same, and the total increases to $3.50. A dime and a quarter have a value together of $0.35. Since there are equal numbers, the value $3.50 must be made up of some quantity of groups with a value of $0.35. That number of groups must be ...
... $3.50/$0.35 = 10
Thus, there are 10 quarters and 10-7 = 3 dimes.
_____
<em>Using an equation</em>
Let q represent the number of quarters. Then the amount Bess has is ...
... 0.10(q -7) +0.25q = 2.80
... 0.35q - 0.70 = 2.80
... 0.35q = 3.50 . . . . . add 0.70 . . . . . . . this should look familiar
... q = 3.50/0.35 = 10
Answer:
no
Step-by-step explanation:
3 is the x coordinate/ integer and -4 is the y coordinate and the integer so it wouldn't make sense
x= 3 is a solution
and id you don't understand the first thing i said watch this
#1. 3, - 4
#2. x= - 4
#3. substitute/replace the x with what the x coordinate is
#4. it will be 3= - 4
#5. as you can see the numbers don't equal each other so it's a no solution
Answer:
Step-by-step explanation:
F(x) is another name for y
If you make a table of values, you can plot the coordinates of this quadratic equation.
When "x" is 0, y is 3
