Answer:
18 and 65
Step-by-step explanation:
under 18 would be 17 and under, therefore not including 18 year olds. obviously they are not 19 yet either, so they wouldn't fall into either category, therefore they may be unsure of what to answer.
same with 65 year olds; they are more than 64 year old, but not yet /over/ 65, therefore they would not fit into either category either.
Answer:
The correct option is option 3
Step-by-step explanation:
Monomials are algebraic expressions that contain one term. It can be variables combined together to make one single term. It can be a single variable combined many times. As long as it is one single entity, it is a monomial
Given the formula for the area of the right angles triangle above to be
A =1/2bh
Where
b = 6x = base of the right angle triangle and
h = 7x = height of the right angle triangle.
The area would be
A = 1/2 × 7x × 6x
A= 42x^2 / 2
A= 21x^2 inches^2
Also written as
21x^2 squared inches
21x^2 is a monomial
Jeremy=x
Older sister=x+5
younger sister=x+5-9 or x-4
x+(x+5)+(x-4)=49
combine like terms
3x+5-4=49
3x+1=49
subtract 1 from both sides
3x=48
divide both sides by 3
x=16
Jeremy=16
Older sister=16+5=21
younger sister =16-4 or 16+5-9=12
J=16
OS=21
YS=12
