Answer:
Evaluate the terms inside of the parentheses
Step-by-step explanation:
According to PEMDAS, you always start solving an equation by answering what is inside of the parentheses first. (That's what the 'P' in PEMDAS stands for!)
Therefore, this is the correct answer.
Answer:
ok first we have to add the number of lollipops up
9+13+5+11+7+15=60
so there is 60 lollipops in total
now we have to add up the ones with out a chocolates center
11+7+15=33
so 33/60
we can simplify this
11/20
now we multiply both by 5
55/100
so 55%
Hope This Helps!!!
F(t)=30 sin(pi/3 t)-15
when sin(pi/3 t) = 1, f(t) = 15 => max.
when sin(pi/3 t) = -1 f(t) = -45 .+ min.
period = 2π / (π/3) = 6 hrs.
Hey there!
If you look at the image you've been given, you can see that there are four complete repeats of each individual angle. What I mean by this is that you can take that angle, lay it on top of three other angles you've been shown, and it will be the exact same. These are corresponding angles.
An example would be (1, 9, 3, and 11). Any of these are the exact same angle, placement and degree included, as the others. The other examples in this problem would be (2, 10, 4, and 12), (6, 14, 8, and 16), and (5, 13, 7, and 15).
Your answer will be C, angle 3 and angle 11.
Hope this helped you out! :-)
Answer:
The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other. Then you back-solve for the first variable.
Step-by-step explanation:
Solve the following system by substitution.
2x – 3y = –2
4x + y = 24
The idea here is to solve one of the equations for one of the variables, and plug this into the other equation. It does not matter which equation or which variable you pick. There is no right or wrong choice; the answer will be the same, regardless. But — some choices may be better than others.
For instance, in this case, can you see that it would probably be simplest to solve the second equation for "y =", since there is already a y floating around loose in the middle there? I could solve the first equation for either variable, but I'd get fractions, and solving the second equation for x would also give me fractions. It wouldn't be "wrong" to make a different choice, but it would probably be more difficult. Being lazy, I'll solve the second equation for y:
4x + y = 24
y = –4x + 24
Now I'll plug this in ("substitute it") for "y" in the first equation, and solve for x:
2x – 3(–4x + 24) = –2
2x + 12x – 72 = –2
14x = 70
x = 5
