Answer:
t = 5.39
Step-by-step explanation:
h = 6 + 33t - 162
Insert the height that they gave you for h (22) and solve for t .
22 = 6 + 33t - 162
add 162 to both sides
184 = 6 + 33t
subtract 6 from both sides
178 = 33t
divide both sides by 33
178/33 = 33t/33
5.3939 = t
Rounding to nearest hundredth t = 5.39
There are no other values that will work.
5.75+ 0.75x is your answer because the only thing that will change is the number of pounds
Answer:
See below
Step-by-step explanation:
This is a system of equations. That means you are trying to find the point that makes both lines true at the same time.
To do this you have to solve for one variable at a time. Luckily, these equations already have one variable that will cancel. If you add 2x and -2x, you get 0. I'm going to line these up like a vertical math problem to show you how it works.
-2x + 3y = 12
2x +3y = 0 Add together
-------------------
0x + 6y = 12 Simplify by removing the 0x
6y =12 Divide both sides by 6 to solve for y
y = 2
Plug 2 in for y in one of the original equations.
2x + 3(2) = 0
2x + 6 = 0 Subtract 6 from both sides
2x = -6 Divide by 2 to solve for x
x = -3
The point that makes both lines true is (-3,2). This is where the lines intersect.
Answer:
Let us check these out one at a time:
1. x + y is odd. FALSE. The sum of 2 odd numbers is even.
2. xy is odd. TRUE. The product of 2 odd numbers is odd.
3. x/y is odd. TRUE. The ratio of 2 odd numbers is odd, if the ratio is an integer.
4. x - y is odd. FALSE. The difference of 2 odd numbers is even.
Only statements 2 and 3 are TRUE, so that makes (C) the correct answer.
The two angles are consecutive angles which makes them congruent so u set them equal to each other. 14x+18=116. subtract 18 from both sides and divide by 14. x=7
