Answer:
P = 2(2y+3)
P = 30
Step-by-step explanation:
P = 2 (L+W) or P = L + L + W + W
P = 2 (2y+3)
P = 4y+6
Plug in 6 for y.
P = 24+6
P = 30
Answer:
b = 55°
c = 35°
Step-by-step explanation:
b° = 180° - (85°+40°) = 180° - 125° = 55°
c° = 180° - (b°+90°) = 180° - (55°+90°) = 180° - 145° = 35°
T
adds 6
t-6
divides by 6
(t-6)/6
shawn
7+t
divide by 7
(7+t)/7
theyare equal
(t-6)/6=(7+t)/7
times 42 both sides
7(t-6)=6(t+7)
distribute
7t-42=6t+42
minus 6t both sides
t-42=42
add 42 both sides
t=84
Answer:
m = -1
Step-by-step explanation:
12 times the number is 12m
17 less than that is 12m -17.
23 less than 6 times the number is 6m-23.
These expressions are said to be the same:
12m -17 = 6m -23
6m -17 = -23 . . . . . . . . subtract 6m from both sides
6m = -6 . . . . . . . . . . add 17 to both sides
m = -1 . . . . . . . . . divide both sides by 6
The value of m is -1.
Answer:
√
42 lies between 6 and 7
Step-by-step explanation:
We know that √
42 will lie between √
36 and √
49
And √
36
=
6 ; √
49
=
7
Hence we can be sure that √
42 lies between 6 and 7
