You can use a guess and check method.
We know .50halfdollar
we know .05 nickels
.50(26) + (.05)(8)=$13.40
13.00+.40=13.40
So, 26 half dollars and 9 nickels
A function is a relation that maps to each input value exactly one output value.
Given the function as {(0,1), (2,3), (5,8), (7,2)}, you can rewrite it
- f(0)=1;
- f(2)=3;
- f(5)=8;
- f(7)=2.
Now consider all options:
- the ordered pair (0,2) cannot be add to this function, because then f(0)=2, but you have already that f(0)=1 and output value should be one value;
- the ordered pair (5,3) cannot be add to this function, because then f(5)=3, but f(5)=8 (given) and output value should be one;
- the ordered pair (7,0) cannot be add to this function, because then f(7)=0, but f(7)=2;
- the ordered pair (1,3) can be add to the set, because f(1)=3 is unique ordered pair (with 1st coordinate 1)
Answer: correct option D
Answer:
b= 352/3
or b= 117.33
Step-by-step explanation:
262-3x+85=-5
-3x+(262+85)=-5
simplify the arithmetic
-3x+347=-5
Group all constants on the right side of the equation
-3x+347=-5
Subtract from both sides:
-3x+347-347=-5-347
Simplify the arithmetic:
-3x=-5-347
-3x=-352
isolate the x
-3x=-352
Divide both sides by -3
-3x/-3}=-352/-3}
Cancel out the negatives
3x/3}=-352/-3
Simplify the fraction
x= -352/-3
Cancel out the negatives
x=352/3
3/5 people means 60% prefer televisions.
60% of 5000 is equal to 0.6*5000=3000
Final answer: D
