X=children
y=adults
1.50x+4y=5050
after its solved
x=700 children
The expression looks like: 3y-7
In your problems that ask the position of the ant labeled as B if they are crawling in a straight wire which shall call the x axis form a to b to c to d the answer to you problem base on my calculation and by understanding the best answer would be 59cm
Answer:
Joey has 18 nickles and 27 dimes in his piggy bank.
Step-by-step explanation:
1 nickle = 5 cents
1 dime = 10 cents
$1 = 100 cents
$3.15 = 135 cents
Let
n represent the number of nickles, n>=0
d represent the number of dimes, d>=0
Joey counted a total of 45 coins that added up to $3.15:
n + d = 45
5n + 10d = 315
n = 18 nickles
d = 27 dimes
First, split up the shape into multiple other shapes. We can split it into two triangles, two different triangles, and a square.
The square has area 6.
The first triangle measures 3 x 1, meaning that the area is 3/2. Since we have two, their combined area is 3.
The other two triangles measure 4 x 1, meaning that their area is 2. Since we have two, their combined area is 4.
Thus, the area is 3 + 4 + 6 = 13.
