The sum of all three angles of a triangle is always 180 degrees.
Step-by-step explanation:
4)
45 + 35.8 = a
180 - a = ?
5)
100 + 40.7 = a
180 - a = ?
6)
90 + 16.5 = a
180 - a = ?
ANSWER:
4) x = 99.2 (a is 80.8)
5) x = 39.3 (a is 140.7)
6) x = 73.5 (a is 106.5)
Answer:
Step-by-step explanation:
5a. 7 < x
b. 2< 2x
c. 8 > x
d. 3 > x/29
joe = j
christina = c
Aaron = a
j = 3a , c = a-6 total ages is 149
149 = j + c+ a
149 = 3a + a-6 + a
149 = 5a-6
add 6 to both sides
149 + 6 = 5a-6+6
155 = 5a
a = 155/5
a = 31
c = a - 6
c = 31 - 6
c = 25
Answer:
3n - 7 = 5
n = 4
Step-by-step explanation:
3n - 7 + 7 = 5
3n = 12
3n/3 = 12/3
n = 4
Let's say Diana is "x" years old today.
in 3 years, she's going to be " x + 3 " years old.
33 years ago, she was " x - 33 " old.
how much is 4 times that anyway? well 4(x-33), that's 4 times as 33 years ago her age.
now, we know in 3 years, x+3, she'll be "<span>4 times as old as she was 33 years ago", 4(x-33), therefore, those amounts are equal then,
</span>

<span>
why is it most logical to use "x" for her age today?
well, because 3 years from now is just x + 3
and
33 years ago is x - 33, 4 times that is 4( x - 33 ).
works very well as a point of reference.</span>
The answer to = 2x27 is f(x)
