Answer:
1 - expressions that are equal in value even though they are written in different ways, 2 - a(b + c) = ab + ac, or a(b + c) = ab - ac, 3 - a number that divides evenly into another number; a number multiplied to get a product, 4 - a single term; multiple terms connected by an addition or subtraction sign, 5 - a mathematical statement that shows two expressions are equal using an equal sign, 6 - an expression that uses variables to state a rule, 7 - a relation in which for any given input value, there is only one output value.
It has to be 30,40,50
Due to Pythagoras Theron it suggests that longer sides is a*2 and b*2 and 30 and 40 square is 2500
2500 square is 50 meaning it makes this statement true
All others are wrong
Answer:
24 people in the history class.
Step-by-step explanation:
Let the total number of people in the class = x. I do this rather a long way because people often have trouble dealing with the division of fractions.
Equation
75/100 * x = 18 Multiply by 100
Solution
75x = 18*100
75x = 1800 Divide by 75
x = 1800/75
x = 24
There are 24 people in the class
Answer:
There would be 21 vertices.
Step-by-step explanation:
Remember that the Euler's formula states that
V - E + F = 2
According to the problem V = F , so
2V - E = 2
and E = 40. Therefore
2V - 40 = 2 and , V = 21 , and there would be 21 vertices.
Answer:
$17.50
Step-by-step explanation:
10 drinks = $25
1 drink = $25/10 = $2.50 per drink
7 x 2.50 = $17.50
7 drinks will cost $17.50
