If x is more than y 12 units, y is the product of 8 and 13, but x smaller than z 111 units and 12 tens, find the value of (x+1+[y-2-{z+3)+2+x]+y-1}
Let a+8#11-2 be defined by 2(a-8)(11+a). For example , 10+8#11-2=2(10-8)(11+10)=2x2x21=4x21=84. Find the value of:
a)12+8#11-2 b)(11+8#11-2)+(13+8#11-2)+708
Let @ a + 2 # 8 is the value of \(2a\left(8+a\right)\times\left(2+8\right)\). For example , @ 4 + 2 # 8 = 2 x 4 ( 8 + 4 ) x ( 2 + 8 ) = 8 x 12 x 10 = 960. What is the value of ( ( @ 9 + 2 # 8 ) + 223 x 8 ) + 8388608 ?
Find x; y , know that x and y is postive ỉterger to be satisfied 2 calculations:
1) xy = yx
2) \(x\times y=8\)
Let @a#b@ is the value of \(\left(a+8\right)\times\left(6-b\right)\). For example , @2#6@ = ( 2 + 8 ) x ( 6 - 6 ) = 10 x 0 = 0. Find the value of @8#3@ ?
Let #a# is the value for \(a\times3\times2\times1\). For example, #8# = 8 x 3 x 2 x 1 = 48. What is the value of #35# ?
The triangle ABC has the perimeter is 80m. If edge AB=1200mm, edge BC=180cm; what is the length of edge CA ?
