Answer:
-7/6
Step-by-step explanation:
2x-8x+7=0
combine like terms
6x+7=0
subtract the 7 from both sides
6x=-7
divide 6 from both sides
-7/6 or -1 and 2/3
Answer:
![\[t\leq -13\]](https://tex.z-dn.net/?f=%5C%5Bt%5Cleq%20-13%5C%5D)
Step-by-step explanation:
Given inequality is ![\[−3t\geq39\]](https://tex.z-dn.net/?f=%5C%5B%E2%88%923t%5Cgeq39%5C%5D)
Simplifying:
![\[-t\geq \frac{39}{3}\]](https://tex.z-dn.net/?f=%5C%5B-t%5Cgeq%20%5Cfrac%7B39%7D%7B3%7D%5C%5D)
![\[=>-t\geq13\]](https://tex.z-dn.net/?f=%5C%5B%3D%3E-t%5Cgeq13%5C%5D)
Sign of the inequality changes of making both sides negative.
![\[=>t\leq -13\]](https://tex.z-dn.net/?f=%5C%5B%3D%3Et%5Cleq%20-13%5C%5D)
Hence the solution for the given inequality is represented by
This means that the original inequality will be true only for those values of t which are less than or equal to -13.
Answer:
1 ) 180 - 71 = 109
2) 5x +x = 180 ; 6x = 180 ; x = 180/6 = 30
3) 90
4) x + 6x+8 + x+12 = 180 ; 8x + 20 = 180 ; 8x = 160/8= 30
5) 180 -110 = 70
6) m = 180- 119 = 61
7) 90
8) 11y - 36 = 63 ; y = 99/11 = 9
~~~~~~~~Next page~~~~~~~~~~
(Q7) 180
(Q8) 2x+x = 3x = 90 ; x = 90/3 = 30
(Q15) 157
(Q16) 5x + 4 + (x-2) + (3x+7) = 180
9x +9 = 180 ; x = 171 / 9 = 19
I hope im right!!
So basically you need to multiply 3000x4000 in two ways? If so you can use basic multiplication and an area model
I think the answer is 2^12
because ...
16^3 is equal to 4,096
and 2^12 is also equal to 4,096
