Answer:
X = 7/3y - 10/3
Step-by-step explanation:
Add - 7y to both sides = -3x + 7y = 10 - 7y
= -3x = 10 - 7y
Divide both sides by -3
-3x/-3 = 10/-3 - 7y/-3
x = 7/3y - 10/3
Answer:
see explanation.
Step-by-step explanation:
2(10 * 4 * 7) is a surface area.
7 * 4 * 10 is volume.
2(10 * 4 + 10 * 7 + 4 * 7) is surface area.
10 + 4 + 7 is neither.
2 * 7 * 4 + 2 * 10 * 7 + 2 * 4 * 10 is neither.
hope this helps.

Step-by-step explanation:
∑₁¹⁰
We have to use the formula of sum of a G.P. series with common ratio r < 1.
If the first term is a, the common ratio is r and the number of terms is n then the sum [a + ar + ar² + ar³ + ......... up to n terms] is given by
