First multiply the parenthesis:
20 - b = 1/3b + 16/3
Then combine like terms:
20 -b + b = 1/3b + b + 16/3
20 - 16/3 = 1/3b + b + 16/3 -16/3
20 - 16/3 = 1/3b + b
44/3 = 4/3b
and if your looking for b;
44/3 (divided by) 4/3 = b
11 = b...is your final answer!
hope it helped :)
It's the second one which is B becasue, first you minus 3w on both sides of your equal side. Then you will have 3L=18-3w. Next you will have to divided by 3 on both sides of the equal sign, you will have L=18-3w/3. Afte that you will simipfy and get your answer, which is B. Please get a brainiest point.
Given- 90% of runner completed the marathon.
out of which 30% are man.
To proof - let the total number of runner be y.
the men completed the marathon be 30% of the 90%.
thus we have
30% of 90% of y = 270
×
×y = 270
now solving the above equation
we get
Thus solving the equation
y = 1000
Thus the total runners of men who completed marathon be 1000.
Hence proved
Answer:
Hey!
Your answer should be
Step-by-step explanation:
To find the BASE: 8 x 4 = 32cm^2
To find the angled TOP FACE: 10 x 4 = 40 cm^2
To find the TRIANGLES: (6x8)/2 x 2 = 48 cm^2
To find the REAR FACE: 6 x 4 = 24 cm^2
TOTAL: 32 + 40 + 48 + 24
SUFACE AREA: 144cm^2
Hope this helps!
D because the parallel sides are both considered bases
