What is 2x=y-10 x+7=y

Mathematics
1 answer:
Triss [41]3 years ago
8 0

Answer:

x = -3

y = 4

Step-by-step explanation:

first i plug y=x+7 for y on 2x=y-10

this makes it 2x=x+7-10

then i solve 7-10 to get 2x=x-3

i subtract -x from both sides to get x=-3

so i plug in x=-3 to x+7=y to get -3+7=y which makes y=4

Hat is he probability of pick 1 green marble from a bag with 7 green and 8 blue marbles
disa [49]

Answer:

7/15

Step-by-step explanation:

<em>No. of green marbles in the bag= 7</em>

<em>No. of blue marbles in the bag= 8</em>

<em>Total no. of marbles in the bag= 7+8=15</em>

As we know that,

Probability( of a random event A)= \frac{Favourable\ no.\ of\ elementary\ events}{Total\ no.\ of\ elementary\ events}

Hence in this case,

Favourable np. of elementary events (green marbles)=7

Total no. of elementary events (Total no. of marbles in the bag)= 15

Hence, Probability of picking a green marble from the bag=\frac{7}{15}

Please help with geometry
Bumek [7]
A. 19. You have to set them up equal to each other. So, 6x-2=4x+36. You then subtract the 4x from the 6x, and add 2 to 36. Which leaves you with 2x=38. Divide and you get 19! Hope this helps
