Answer:
sorry im not sure about the answer but this is how you figure it out
Step-by-step explanation:
50a+30b=550
after you simplify = 5a+3b=55
44a+36b=532
after you simplify=11a+9b=133
then you try to find a number
5a+3b=55
then you have to find different possibilities of a and b and if it can fit into both equations then it is correct
area=3136sq.cm
height=perpendicular=64 cm
base=?
area=1/2*base*height
3136=1/2*base*64
therefore,, base=98
Please can you give me brainliest
3x + 2y = 10 .....multiply by -2
2x + 3y = 15/2...multiply by 3
------------------
-6x - 4y = -20 (result of multiplying by -2)
6x + 9y = 22.5 (result of multiplying by 3)
-----------------add
5y = 2.5
y = 2.5/5
y = 1/2
3x + 2y = 10
3x + 2(1/2) = 10
3x + 1 = 10
3x = 10 - 1
3x = 9
x = 9/3
x = 3
solution is (3,-1/2)
Step-by-step explanation:
-3(2x-6)+4=-6x+18+4=-6x+22
Total length = 111.6 metres
(12.3x7) + 15 + 10.5 = total length
