Answer: 102 children and 41 adults swam at the pool that day.
Step-by-step explanation:
Let x represent the number of children that swam at the public pool that day.
Let y represent the number of adult that swam at the public pool that day.
On that certain hot summer's day, 143 people used the public swimming pool. It means that
x + y = 143
The daily prices are $1.25 for children and $2.25 for adults. The receipts for admission totaled $219.75. It means that
1.25x + 2.25y = 219.75- - - - - - - - -1
Substituting x = 143 - y into equation 1, it becomes
1.25(143 - y) + 2.25y = 219.75
178.75 - 1.25y + 2.25y = 219.75
- 1.25y + 2.25y = 219.75 - 178.75
y = 41
x = 143 - y = 143 - 41
x = 102
Answer:
1
for each 2 inches you get 2 feet so its 2 to 2 divide that down and its 1 to 1
Step-by-step explanation:
Answer:
Let
The subset S is a subgroup of GL(n,R) if satisfies:
1. The identity matrix belong to S.
2. If A and B are in S then AB is in S.
3. If A is belong to S then belongs to S.
Let's see if S satisfies these conditions.
1. We know that , then .
2. Let A and B in S.
Then AB is in S.
3. Let , , then .
Since S satisfies all conditions then S is a subgroup of GL(n,R).
There is 2.54 centimeters in an inch.
Answer:
h(x) = 2x - 8
Step-by-step explanation:
Step 1: Define
f(x) = -2x
g(x) = 4x - 8
h(x) = f(x) + g(x)
Step 2: Find h(x)
h(x) = -2x + 4x - 8
h(x) = 2x - 8
