x=0 or x=4
just factorize basically
cancels the x’s so it’d be 3x-12=0 and from that x=4
A+b+c=28x+40=180
—>28x=140
—>x=140/28=5
c=9x-3
—>c=42
Answer:
3/10
Step-by-step explanation:
1/5 of <u>total</u> income - spent on car
<u>remainder</u><u> </u> income = 4/5
3/8 of <u>remainder</u><u> </u>= 3/8 ×4/5 = 3/10(of total income spent on rent)
the word "<u>of</u>" means you can find it by multiplication
e.g. 2 of 1/2 means 2 × 1/2 which is 1
Answer:
x ≈ 46°
Step-by-step explanation:
Since the triangle is right use the sine ratio to solve for x
sinx = 
= 
, hence
x = 
( ) ≈ 46°
Answer:
x > 28/3
Step-by-step explanation:
34 > 3(2 − x)
simplify the bracket
34 > 6 -3x
combine the like terms
34 - 6 > 3x
28 > 3x
divide by 3
x > 28/3
Sorry I don't know how to graph here, but I can graph it by writing the way it can be graphed.
It is in slope intercept form; y = mx + b
where mx is the slope and b is the y-intercept;
x>28/3; where 28/3 is the slope which means; at the y-intercept, go up 28 times and to the right 3 times
And b is 0; which means at 0 where the slope will be applied, go up 28 times and to the right 3 times.
Hope this helps!
Good luck.
