Answer:
x=22°
Step-by-step explanation:
Opposite angles are equal, so that must mean that:
3x-14 = 4(x-9)
expand the brackets.
3x-14 = 4x-36
And then rewrite to get x on one side, by minusing 3x on both sides.
-14=x-36
Add 36 on both sides.
22 = x
so, x=22°
Answer:
16 cm
Step-by-step explanation:
Suppose that <em>x</em> is the original width. If that original width is enlarged by a scale factor 5/2 that means that <em>x</em> is multiplied by 5/2 and after that multiplication we obtained new width, 40 cm.
Therefore,
x*(5/2) = 40
We multiply the equation by 2 and obtain:
x*5 = 40*2
5x = 80
Now we divide the equation by 5 and obtain:
x = 80/5
x = 16
We obtained that <em>x</em>, the original width was 16 cm
Answer:
x = 1/7(k+12)
Step-by-step explanation:
7x - 12 = k
Add 12 to each side
7x - 12+12 = k+12
7x = k+12
Divide each side by 7
7x/7 = (k+12)/7
x = 1/7(k+12)
D. -4,-5,-6,-7
and if it was wrong i’m sorry
120 divided by five is 24. That times three is 72. That minus 15 is 57. So yes you could and you would have extra
