You first subtract and a e. E see where that gets you subtract or add the first number
Answer:
a) x > − 24 
b) x < − 3
c) q < 56
Step-by-step explanation:
a) −2/5x−9<9/10
<=> 2/5x + 9 > − 9/10
<=> 2/5x > − 9/10 − 9
<=> 2×2/2×5x > − 9/10 − 9×10/10
<=> 4/10x > − 99/10
<=> x > − 99/4
<=> x > − 24
b) 4x+6<−6
<=> 4x < − 6 − 6
<=> 4x < − 12
<=> x < − 12/4
<=> x < − 3
c) q+12−2(q−22)>0
<=> q+12−2q −2×(−22)>0
<=> (q−2q) + (12+ 44) >0
<=> −q + 56 >0
<=> q < 56
Y varies inversely with x
y = k/x
when y = 0.5, x = 3
0.5 = k/3
k = 0.5 x 3 = 1.5
k = 1.5
y = 1.5/x or y = 3/2x
Answer:
Terminating
Step-by-step explanation:
The decimal does not go on forever, therefore it is a terminating decimal.
Answer:
-1711005
Step-by-step explanation:
using BODMAS that implies you multiplication(M),before addition(A), then substraction(S) which comes last.
use the above rule to get the variable without letter only.
so ( 2*2)+(-3)=1
then 1-9=8, this part is for the left hand side which gives us 4x-8.
then the right hañd side 3-173-5133193 not including the variable with the letter x.now we have:1x-5133023.
so now
4x-8=1x-5133023
collect like terms
4x-1x=-5133023+8
3x=-5133015
divide both side by 3
x= -1711005
