Answer: 90
Explanation: The pattern is add 3 then the next set is double. [9-6=3 then 18-9=9(or doubled)] and the pattern continues and because 45-42=3 the next number set would be 45 doubles which equals 90.
Answer:
a. x = 22
b. Perimeter = 100
Step-by-step explanation:
a. Based on the proportionality theorem, we have the following:
(2x - 4)/8 = (36 - 6)/6
(2x - 4)/8 = 30/6
(2x - 4)/8 = 5
Cross multiply
2x - 4 = 8*5
2x - 4 = 40
2x = 40 + 4
2x = 44
x = 44/2
x = 22
b. Perimeter of ∆JKL = KJ + KL + JL
KJ = 2x - 4 + 8
Plug in the value of x
KJ = 2(22) - 4 + 8
KJ = 44 - 4 + 8 = 48
KL = 36
JL = 16
Perimeter = 48 + 36 + 16
Perimeter = 100
Answer:
x = 15
Step-by-step explanation:
Its 15 degrees in celsius
Let's eliminate x in the system
<span>
2x-5y=-5
x+2y=11
To do this, mult. the 2nd eqn by -2:
</span> 2x-5y=-5
-x-4y=-22
---------------
-9y= -27. This yields y = 3.
Now subst. 3 for y in either of the original equations to determine x.
Write your answer as an ordered pair: ( ? , 3).
