Let x be the brick portion of the wall
Since x is 2/3 of the wall
Then x= (2/3)(2 3/4)
x= 11/6 = 1 5/6
So the brick portion of the wall is 1 5/6 feet
Note: that's not 15/6, it's a mixed fraction which is 1 + 5/6.. just to let you know
Answer:
Um I Dont Know
Step-by-step explanation:
Answer:
27(less than symbol) 5x+7
Step-by-step explanation:
5 times a number is 5x
increase means add
13x - 6y = 2......multiply by 2
3x - 4y = -10....multiply by -3
------------------
26x - 12y = 4 (result of multiplying by 2)
-9x + 12y = 30 (result of multiplying by -3)
-----------------add
17x = 34
x = 34/17
x = 2
now sub 2 in for x into either of the original equations to find y
3x - 4y = -10
3(2) - 4y = -10
6 - 4y = -10
6 + 10 = 4y
16 = 4y
16/4 = y
4 = y
solution is (2,4)
