The women's shadow would be 36.6ft. long.
You have to set up a proportion 42.9 6.2
--------- = ------------
253.1 X
Then you cross multiply (6.2*253.1) and divide (1569.22/42.9) equals 36.6
Ex: solve for x
x+3=7 since I want to get x by itself i remove the three.
x+3-3=7-3 The opposite of plus 3 is minus 3, and whatever I do to one side i MUST do to the other side, so you want to subtract 3 from both sides.
x=4 so, 3 minus 3 = 0 and 7 minus 3 = 4.
Answer:
1: x = 19 y = 16 ; 2. x = 5 y = -4
Step-by-step explanation:
To check your work plug the numbers back into one of the equations and see if it's true.
For example:
10(19)-9(16)=46
46=46
1. I distributed 3 to all the numbers so that 9y and -9y would cancel then you add like terms.
2. I distributed -4 to all the numbers so that 4x and -4x would cancel. Then add all like terms.
Once you get x or y plug it back into one problem to get the other variable.
Hope this helps!
X=15 since you subtract 1 from 27 then subtract 12 from 27 and you get 15
You could expect about 1,248 students to play at least 4 hours every week.
Our tables have 100 students involved. All but 4 of the students are in the category of at least 4 hours. That is 96%.
Therefore, we simply need to multiply 0.96 by 1300 to get the estimated amount.
0.96 x 1300 = 1248
