Let X represent the number of hours you travelled
Let B represent number of hours Brian travelled
Equation 1 is X + B = 20 (since combination of number of hours you and Brian travelled equal to 20 hours)
Equation 2 is M = 5B (since you travelled five times more than the amount in which Brian travelled)
Plug Equation 2 into Equation 1 (replacing M with its value)
5B + B = 20
Rearrange equation to make B its subject (find B)
6B = 20
6B/6 = 20/6
B = 3(1/3)
Brian travelled a total of 3(1/3) (three and a third) hours.
(1/3) of an hour = 60/3 or 60*(1/3) = 20mins
Brian travelled a total of 3hrs & 20mins.
Plug B value back into Equation 1
M + B = 20
M + 3(1/3) = 20
Rearrange equation to make M its subject (find M)
M = 20 - 3(1/3) = 16(2/3)
You travelled a total of 16(2/3) (sixteen and two-thirds) hours.
(2/3) of an hour = 60/3*2 or 60*(2/3) = 40mins
You travelled a total of 16hrs & 40mins.
Answer:
The missing side length is 27 in
Step-by-step explanation:
see the attached figure
we know that
1 ft= 12 in
step 1
Convert ft to in
2 ft=2*12=24 in
Note ----> the given measure is 13 in instead of 13 ft
step 2
Find the missing side length
The perimeter of a quadrilateral is the sum of its four side lengths
Let
x------> the missing side length
P=x+24+13+15
P=79 in
so
79=x+24+13+15
x=79-52=27 in
The missing side length is 27 in
Answer:
check all below
Step-by-step explanation:
#1
1/6)^3
1/26 so answer 1 on number one
#2 what the heck is this 65+75= 140 not 120
65/120 = 54.16666% * 12600 = 6825 so 3
or 65/140 = 46.428% * 12600 = 5850
#3 number 4 makes the most since sense you get the WHOLE POPULATION
#4 1/5*1/2 or 1/10 = .10 * 100% = 10% or 3
#5
6+2+8+4 = 20
2 red marbles
2/20 = 1/10 = .10 * 100% = 10% or 2
