Answer:
x = 20.
Step-by-step explanation:
1/2x + 40 = 50
1/2x + 40 - 40 = 50 - 40
1/2x = 10
1/2x * 2 = 10 * 2
x = 20
Answer:x=13
Step-by-step explanation:
3/5 (x+2)=x-4
Please refer to the figure attached for the diagram of this problem.
Steps needed to find the width of the field (CD):
First, we should note that angle d would be equal to 27 degrees because there are two parallel lines that are cut by a transversal. Furthermore, angle a would be equal to 5 degrees since we just need to subtract 27 from 32.
We then subtract 27 and 5 from 180 to get angle c.

. Angle c is therefore 148 degrees.
Next, we need to find angle e which is just the supplementary of angle c. Angle e therefore measures

degrees.
For the next step we use sine law to find the length of segment AC:


Lastly, we need to utilize the sine law again to find the length of segment CD or the width of the field:

ANSWER: The width of the field is 290 ft.
Answer:

Step-by-step explanation:
Well the diagonal using pythagora's theorem:
where x is the lenght is the side of the square
so when x=4

when x=7

when x=13

Answer:
They have enough.

Step-by-step explanation:

4 = 2 × 2
3 = 3 × 1
LCM of 4 and 3
= 2 × 2 × 3 × 1
= 12
