2(x-7)/3=-2
3*2(x-7)/2*3=-2*3/2
x-7=-2*3/2
x-7=3*-1
x+(7-7)-7-3
x=7-3
x=4
Answer:
-1280
Step-by-step explanation:
Given a₁ = -10, n = 8, r =2
Required to find nᵗʰ term.
From the general formula: aₙ= a₁ (r)ⁿ⁻¹
Therefore nᵗʰ = -10(2)⁸⁻¹
= -10(2)⁷
= - 10(128)
= - 1280
Answer: x=7, EF=12, FG=15
Step by Step:
(4x-16) + (3x-6) = 7x-22
7x-22=27
7x=27+22
7x=49
x=7
4(7)-16= 12
3(7)-6=15
Answer:
3x – 2 = 16
