Hi there! :)
Answer:

m∠BGC = 16x - 4
m∠CGD = 2x + 13
m∠BGC + m∠CGD sums up to 90°, therefore:
(16x - 4) + (2x + 13) = 90
Combine like terms and simplify:
16x + 2x - 4 + 13 = 90
18x - 4 + 13 = 90
18x + 9 = 90
18x = 81
18x/18 = 81/8
x = 4.5
Answer:
11y
Step-by-step explanation:
33xy/3x
33/3=11
x/x=1
so we have
33xy/3x=11y
Answer:
x=4
Step-by-step explanation:
"A number" can be rewritten as X:
6x=3x+12
1) subtract 3x on both sides:
3x=12
2) divide both sides by 3:
x=4
6 7/8= 55/8
6 1/6= 7/6
first find common denominators
55/8 * 3= 165/24
7/6 * 4= 28/24
165/24 divided by 28/24 is the same as 165/24 time 24/28
so that equals 3960/672
which equals 5.8928
so estimates about 5 shelves<span />
