Answer:
3(2) - 5 = 1
Step-by-step explanation:
y = 3x - 5
(x, y)
plug x and y in
1 = 3(2) - 5
1 = 6 - 5
1 = 1
true
Answer:
Converse: False
Inverse: False
Contrapositive: True
Step-by-step explanation:
Converse: Two angles can be any degree and be congruent, they do not have to both be right angles, which makes this statement false.
Inverse: Same as above. They can be not right angles. If they are the same degree, they are congruent, so they do not have to be right angles, which makes this statement false.
Contrapositive: If angles are congruent, they will not both be right angles, because right angles are the same degree, which makes them congruent. Thus, this statement is true.
Split the problem like this.
you were given that each square is 1cm.
so for the rectangle on the left it goes as followed
a= lxw
a= 3 x 5
a= 15
and now do the rectangle on the right
a= lxw
a= 4x2
a= 8
now just add the two together
a= 8+15
a=23cm
Answer:
56
Step-by-step explanation:
Let Davids's age = d
Let Marie's age = m
First part of the question tells us: d=4+(3m)
Second part of the question tells us: d=m+38
Sub in 'm+38' for d:
m+38=4+3m
3m-m=38-4
2m=36
m=18
d=m+38
=18+38
=56
