6m + 5 - 3m = 7 (m-1)
6m + 2m = 7m - 7
8m = 7m - 7
m = -7

6m + 5 - 3m = 7m-7
3m +5 = 7m-7
-3m -3m
5 = 4m -7
+7 +7
12= 4m
divide both sides by 4
answer should be 3

bagirrra123 [75]

Answer:

12 meters

Step-by-step explanation:

Given

$Scale= 1cm:2m$

Required

Determine the measurement when the scale reads 6cm

Represent this scale with x;

Such that:

$Scale = 6cm:x$

Equate

$Scale= 1cm:2m$ and $Scale = 6cm:x$

$1cm:2m = 6cm:x$

Express as fraction

$\frac{1cm}{2m} = \frac{6cm}{x}$

Cross Multiply

$x * 1cm = 6cm * 2m$

$x * 1 = 6 * 2m$

$x = 6 * 2m$

$x = 12m$
