Start by squaring the numbers on both sides to get rid of the square root on both the left and right sides to get:
x + 5 = 5^2 – x
x + 5 = 25 – x
Then rearrange to make x the subject.
x + 5 = 25 – x
2x + 5 = 25
2x = 20
x = 10
Answer:
The cost of the fencing is $273
Step-by-step explanation:
* Lets explain how to solve the problem
- Sam is planning to fence his back yard
- Every side of the yard except for the side along the house is to
be fenced
- The fencing costs $3/yd and can only be bought in whole yards
- The side of his yard opposite the house measures 35 yd
- The other two sides of his yard are 28 yd
* Lets solve the problem
∵ The length of the yard is the sum of the sides whose to be fenced
∴ The length of the yard = 28 + 35 + 28 = 91 yd
∵ The cost of the fencing is $3 per yard
∴ The cost = 91 × 3 = 273
∴ The cost of the fencing is $273
Answer:
-5/3
Step-by-step explanation:
To solve for slope we use the slope formula which is y2-y1/x2-x1.
For this problem I chose the points: (-5,10) and (-2,5)
-5 is x1, 10 is y1, -2 is x2 and 5 is y2
We now plug in the points into the slope formula:
5-10/-2-(-5)= -5/3
