Step-by-step explanation:
first you have to solve for x
35x - 5=50
35-35x-5= 50-35
x-5=15
x- 5÷5=15÷5
x=3
Now we have to substitute x into the equation.
35×(3)-5=
175-5=170
angle UVW= 170
to find angle HUW instead of solving the equation just subtract 170 from 50 and you will get 120.
angle UVH=50
angle HUW=120
angle UVW=170
I hope this helps srry it took so long but gn and gl.
Answer: 1/6
Explanation: Since we need to draw three cards from a pack of 9 and the digits require an order, then our sample space becomes: 9P3.
Now, we don't care about picking an order when picking three cards to analyse, as there is only 1 way in arranging the three cards in descending order.
Thus, we get:
Multiply 6 and 17 and see if it equals 102
Answer:
R1 = {(1, 7) (2, 7) (4, 7) (6, 7)}
R3 = {(x, y) (y, z) (z, t) (t, v)}
R1 and R3 are functions because first element in the ordered pair is not repeating, i.e they have unique images
The solution for this problem is:
<span>Let time taken by Emily be x </span>
<span>
then Aileen take 2/3 of x = 2x/3 </span>
<span>
1 min work of Emily = 1/x</span>
<span>
1 min work of Aileen = 1/ 2x/3 => 3/2x</span>
<span>
1 min work of both = 1/45</span>
<span>
1/x + 3/2x = 1/45</span>
<span>
5/2x = 1/45</span>
<span>
1/x = 2/225</span>
<span>
Emily take 225/2 mins to complete the work, then Aileen</span>
<span>= 225/2*2/3</span>
<span>= 75 mins.</span>
