Answer: 3j +4
3(j)+ 3(2) = 3j+ 6 - 2 = 3j +4
Hope this helps
Hi,
You can write your problem as:
x = 8 + 3y
x + y = 28
So
(8 + 3y) + y = 28
4y = 28 - 8
4y = 20
y = 20/4 = 5
x + y = 28
x + 5 = 28
x = 28 - 5 = 23
The numbers are 23 and 5.
Hope this helps! If my answer was not clear enough or you’d like further explanation please let me know. Also, English is not my first language, so I’m sorry for any mistakes.
a) 247 ÷ 11 = 22 r.5 <em>since there is a remainder it is not a factor</em>
b) 247 ÷ 13 = 19 there is no remainder so this is a factor! The other factor is 19.
Answer: B, D
Answer: D
Step-by-step explanation:
Let's take one of the equations and solve for a variable to use the substitution method.
Now replace this in the first equation.
Separate the terms.
Solve 20/5
Subtract 4 from both sides to isolate y.
Solve the difference.
Multiply by the reciprocal or the inverted fraction that is next to y to isolate it.
Now, in order to find x, replace y in any of the two equations.
Answer is 80pi
Step by step
To find lateral_area = (2 * π * r) * h
Since it’s in term of pi,
(2 x radius x height) pi
2 x 4 x 6 = 48pi
base_area = 2 * π * r²
Since it’s in terms of pi
(2 x r^2)
(2 x 4^2)
= 32pi
Total surface area in terms of pi = 32+48
= 80pi
