Answer:
3/2
Step-by-step explanation:
21/5×5/14
105/70
divide by 5
21/14
divide both by 7
3/2
Answer:
option 4
Step-by-step explanation:
Solving the inequality
4.5 + 1.2x ≥ 10 - x ( add x to both sides )
4.5 + 2.2x ≥ 10 ( subtract 4.5 from both sides )
2.2x ≥ 5.5 ( divide both sides by 2.2 )
x ≥ 2.5
3, 4, 5, 6 are all greater than 2.5, thus
All values in the set make the inequality true
Totally doable. Just break it into 2 shapes rectangles and triangles.
Rectangles: A=bh
so: 83×60
now since there are 3 rectangles with the same parameters multiply your answer by 3
![83 \times 60 = 4980](https://tex.z-dn.net/?f=83%20%5Ctimes%2060%20%3D%204980)
![4980 \times 3 = 14940](https://tex.z-dn.net/?f=4980%20%5Ctimes%203%20%3D%2014940)
put aside the rectangles.
Triangles:A= 1/2×b×h
so: A= 1/2 ×82× 76
Then multiply your answer by 2 since there are 2 triangles.
This will give you the answer 3116.
Now all that's left is to add the area from the rectangles and the area from the triangles.
Part 2 for your previous question. The third picture is called the Pythagorean theory. The equation is a squared + b squared =c squared. So take the meausurment of the "a" side and square it. Do the same with "b". Next add those two together then square root the answer.
Refer to the next picture. That was an example.
Yes it is correct. I did not notice anything wrong with the given answers.
So what you want to do for all of these is move the variable that you want to be the subject to one side of the equation and the other ones to the other side, then divide.
For example:
With number 1, m = 3n + 2p, since you want to make p the subject, first single out p by subtracting 3n from both sides.
m - 3n= 3n + 2p - 3n
2p = m - 3n
Then divide everything by 2.
2p / 2 = m/2 - 3n/2
p = , you could also say 1/2m - 3/2n
p = 1/2m - 3/2n
Next question: just do the same thing.
a = 3c - 4
a + 4 = 3c - 4 + 4
3c = a + 4
/3 /3 /3
c = 1/3a + 4/3
Next question: same process.
P - 2a = 2a - 2a + 2b
2b = P - 2a
/2 /2 /2
b = 1/2P - a
