Answer:
$196
Step-by-step explanation:
Lets assume,
cost of a belt = 'x'
cost of a pair of pants = 'y'
Now, According to the question;
- x + y = 490;
- cost of a bag = twice the cost of belt = 2x;
- cost of a pair of pants = twice the cost of bag
⇒ y = 2×2x ⇔ 4x
hence, by subtituting the values in equation' we get;
⇒ x + 4x = 490
⇒ 5x = 490
⇒ x = 98
So, the difference between the cost of the pair of pants and the bag ;
⇒ y - 2x
⇒ 4x - 2x
⇒ 2x = 2×98 = 196.
Answer:
he earns 5 dollars for walking 4 dogs
Step-by-step explanation:
Yes
For f(x) to represent a function each value of x from the domain must only map to one unique value in the range, called one-to-one
This is the case here as each value of x maps to one unique value in the range
domain x ∈ {- 5, - 4, 0, 3 }
range y ∈ {0, 2, 10, 16 }
Answer:
he rose by 71 feet and it took him 6.88 mins to do so.
Step-by-step explanation:
So we know that the diver is going up in elevation cause he is ascending and he ascended 71 ft. Along with the fact that the total dive was 20 1/8 mins with roughly converts to 20.13 mins and if we take that number and subtract the amount of time he stayed at the elevation of 71ft we know that it took him 6.88 min to rise to the elevation of -18.9.
