Answer:
There were 300 people at the meeting
Step-by-step explanation:
The number of people who drove to the meeting is equal to the number of people at the meeting times the percentage of people who drove
240 = people *80%
Change this to a decimal
240 = people *.8
Divide each side by .8
240/.8 = people *.8/.8
300 = people
There were 300 people at the meeting

Answer:
x = 3/61
Step-by-step explanation:
Hi there!
49(9x+1) = 14(x+5)
Divide both sides by 7
7(9x+1) = 2(x+5)
Open up the parentheses
63x+7 = 2x+10
Combine like terms
63x-2x = 10-7
61x = 3
Divide both sides by 61
x = 3/61
I hope this helps!
Answer:
SSS
Step-by-step explanation:
Two triangles are said to be congruent if all their three sides are equal and all of their three angles are equal. There are 5 ways of determining congruent triangle which are:
- SSS (side, side, side): This is when the two triangles have all three sides equal to each other.
- SAS (side, angle, side): This is when the two triangles have 2 equal sides and one included angle of both triangles are equal.
- ASA (angle, side, angle): This is when the two triangles have 2 equal angles and one included side of both triangles are equal.
- AAS (angle, angle, side): This is when the two triangles have 2 equal angles and one non included side of both triangles are equal.
- HL (hypotenuse, leg): The hypotenuse is the longest leg of a right angled triangle. If two triangles have equal hypotenuse and one equal leg, they are congruent.
Triangle ABC and triangle BCD are congruent because:
AB = CD, AC = BD and both triangles share the same side BC. That is they have three equal sides (SSS)
Answer:
This depends on the situation. For context, you use less than when your inequality CANNOT exceed more than.
You would use less than or equal to if your inequality can be equal to a number. Here's an example.
John needs to buy X oranges and Y apples. He can AT MOST buy 10 total fruits.
x + y (equal to or less than) 45
John needs to buy X oranges and Y apples. He CANNOT buy more than 10 total fruits.
x + y < 45
