3.2x+5.7=2.5x. X=-8.142857
10.1x-1.6x+44=-7 x=-6
7.9x+x+4=1.1x-16 x=-2.564103
1/4x+5/2x-2=4-1/4x x=2
Answer:
9 × 2^(13)
Step-by-step explanation:
hello :
the nth term is : An =A1 × r^(n-1)
a common ratio is : r and A1 the first term
in this exercice : r= -3-(-7)36/18 = 18/9 =2 A1 = 9
when : n =14 you have the 14rd term A14
A14 = 9 × 2^(14-1) = 9 × 2^(13)
false.No
Step-by-step explanation:
15x+18y=16
(8,2)
15(8)+18(2)=16
120+36=16
156=16
false
56/72 can be simplified to 14/18, then to 7/9 *dividing by 4, then by 2*
28/32 can be simplified to 7/8 *dividing by 4*
70/90 can be simplified to 7/9 *dividing by 10*
7/9 and 7/9 are equivalent, so 56/72 and 70/90 are equivalent.
True i think I don’t really know
