Move the variable to one side by finding common denominator
1/4 - 7/10p = 1/20p
5/20 - 14/20p = 1/20p
+ 14/20p +14/20p
5/20 = 15/20p
Simplify
1/4 = 3/4 p
multiply both sides by 4, then divide both sides by 3
1 = 3p
1/3 = p
Answer:
About 316.13
Step-by-step explanation:
We know:
Diameter (d) = <u>11</u> (of the circle)
Area of the circle: pi(11)^2 = <u>121pi </u>
Side of the square = <u>8 </u>
so area of the square is 8^2 = <u>64</u>
Area of the shaded region:
121pi-64 =316.13

Step-by-step explanation:
Judging from the high of 400, her day 21 appears to be approx 300
if she put in 100 then the next five days she added a total of 200 more to reach 300

Answer:
one solution
Step-by-step explanation:
* Lets start to solve the question
- The 1st equation x - y = -4
- The 2nd equation 3x + y = 8
- We will use the elimination method to solve this system of equation
∵ x - y = -4 ⇒ (1)
∵ 3x + y = 8 ⇒ (2)
- Add the two equation (1) and (2) to eliminate y
∴ x + 3x = -4 + 8
∴ 4x = 4
- Divide both sides by 4
∴ x = 1
- Substitute the value of x in equation (1) or equation (2) to find
the value of y
- We will use equation (1)
∴ 1 - y = -4
Subtract 1 from both sides
∴ -y = -5
- Divide both sides by -1
∴ y = 5
∴ The solution is (1 , 5)
* The system has one solution
