To find the mean. You would add up all the numbers then divide by how many numbers there are.
2.02+24.6+2.88+2.18+2.78+2.35+2.22= 39.03
39.03/7=5.5757
ANSWER: 5.5757
The answer is as follows
x = -3
y = 7
There are a few ways to do this but lets do it the following way.
<span>3x + y = -2
y = -x +4 <--- turn this to standard form
</span>
y = -x + 4
x + y = 4
3x + y = -2
x + y = 4 <---- Times this by -3 to cancel out
3x + y = -2
-3(x + y) = 4 * -3
3x + y = -2
-3x -3y = -12
+ y = -2
-3y = -12
-2y = - 14
-2y / -2 = - 14 / -2
y = 7
Now that we found y we can insert 7 into the y position in one of the equation. For instance
y = -x +4
7 = -x + 4
7 = -x + 4
-4 + 7 = -x
3 = -x
x = -3
Answer:
3(x + 1)(3 - x).
Step-by-step explanation:
(x + 3)^2 - 4x^2
Using the identity a^2 - b^2 = (a - b)(a + b), we have
(x + 3 - 2x)(x + 3 + 2x)
= (-x + 3)(3x + 3)
= 3(x + 1)(3 - x)
Answer:
25π
Step-by-step explanation:
C= πd
d=√(24²+7²)=√(576+49)=√625=25
C=25π
Answer:
The answer is 8 r 3.
Step-by-step explanation:
When you multiply 4 by 8, you get 32. 32 would go in the two boxes below 35 so we can get thw remainder of 3. We get this because 35-32 is 3. The box below 32 would be the 3. Hope this helps :)
