Answer:
4
Step-by-step explanation:
First you solve for x
3x-1 = 2x-4+2x-3-2
3x-1 = 4x-5
You get 4 = x
substitute 4 for x
2(4)-4
8-4
=4
P/L=4/7 and P=L-12 so
(L-12)/L=4/7 multiply both sides by 7
(7L-84)/L=4 multiply both sides by L
7L-84=4L subtract 4L from both sides
3L-84=0 add 84 to both sides
3L=84 divide both sides by 3
L=28, and since P=L-12
P=16
So they had 28+16 = £44 in total.
Answer:
ill explain better
Step-by-step explanation:
use distrubrity property and you get 6x + 6x -18y+6+(-9) then you add 18 because you have to get the y way so you do the opposite of subtracting which is adding so when you add the 18 to it self you then add the 18 to one of the 6x the you get 24x+6x+-4 which u add 6 to -9 the to combine like terms and get 30x+-4
Z=20
A triangle is equal to 180 degrees so 70+90=160
180-160=20
