Answer:
x = 5
Step-by-step explanation:
Angle Bisector Theorem: When a ray bisects an angle, we get 2 congruent smaller angles
Step 1: Set equation equal to each other (Angle Bisector Theorem)
5x + 3 = 7x - 7
Step 2: Subtract 5x on both sides
3 = 2x - 7
Step 3: Isolate <em>x</em> term (Add 7 to both sides)
10 = 2x
Step 4: Isolate <em>x</em> (Divide both sides by 2)
x = 5
This one is correct good job,anymore questions
Answer: A
Step-by-step explanation:
To be able to determine the number of M&Ms that are needed in order to measure the length of Mississippi River, we convert the units to a common one. For this purpose, we convert kilometers to centimeter such that,
Length of Mississippi River = (4000 km)(1000 m/1 km)(100 cm/1 m)
= 400,000,000 cm
Since there are 400,000,000 cm in the entire length of the river, the answer would also be 400,000,000.
x= the number of girls competing
x+16=the number of boys competing
The equation to find the number of boys and girls competing would be:
x+(x+16)=1000
First, combine like terms:
2x+16=1000
Subtract 16 from both sides.
2x=984
Divide both sides by 2:
x=492
We know now that the number of girls competing is 492. To find the number of boys competing, you simply have to add 16 to 492.
492+16=508
There are 508 boys competing and 492 girls competing.
I hope this helps :)
