A. 2/3x=6
B. I chose multiplication because division would be used to find the answer without an equation so I chose the inverse (or opposite) operation
There are 13 cards of each suit.
Picking a heart would be 13/52 which reduces to 1/4
Then replacing the card and picking a club would be the same : 1/4
Picking a heart then a club would be 1/4 x 1/4 = 1/16
Answer: 1/16
Answer: 13 cats were at the shelter on Thursday.
Step-by-step explanation:
Let x represent the number of cats that were at the shelter on Thursday.
Let y represent the number of dogs that were at the shelter on Thursday.
Camden found a record showing that there were a total of 30 cats and dogs on Thursday. This means that
x + y = 30
The animal shelter spends $2.50 per day to care for each cat and $4.00 per day to care for each dog. Camden noticed that the shelter spent $100.50 caring for cats and dogs on Thursday. This means that
2.5x + 4y = 100.5 - - - - - - - - - - - - 1
Substituting x = 30 - y into equation 1, it becomes
2.5(30 - y) + 4y = 100.5
75 - 2.5y + 4y = 100.5
- 2.5y + 4y = 100.5 - 75
1.5y = 25.5
y = 25.5/1.5
y = 17
x = 30 - y = 30 - 17
x = 13
Answer:
√x+3=13
Step-by-step explanation:
The equation is √x+3=13 is radical because the unknown, x appears under a radical sign √.
To solve the equation, the unknown is left on one side of the equal sign and then both sides of the equal sign are raised to an equal power which would remove the radical sign.
For example,
√x+3=13
√x=13-3
√x=10
Removing radical.
(√x)²=10²
x=100
The answer is B! Hoped I help
