Answer:
(2, 13)
Step-by-step explanation:
Since they both equal y, you can equal them to each other.
8x - 3 = 2x + 9
Subtract 2x from both sides.
6x - 3 = 9
Add 3 to both sides.
6x = 12
Now divide 6 on both sides.
x = 2
Now that we have found x, we need to find y. Just plug in x to the equations.
y = 2(2) + 9
y = 4 + 9
y = 13
Now, if the next equal has the same y, then both are true.
8(2) -3 = y
16-3=y
13 = y
So therefor, both x and y are true.
Answer:
1.5 grams of protein.
Step-by-step explanation:
The equation that represents the relationship between protein and fat is as follows :
4p + 9f = 60 ....(1)
We need to find the grams of protein are there if there are 6 grams of fat in the snack.
Put f = 6 in the above equation (1).
4p + 9(6)= 60
4p + 54 = 60
Subtract 54 to the both sides,
4p + 54-54 = 60-54
4p = 6
⇒ p = 1.5 grams
It means the snack contains 1.5 grams of protein.
Answer:
30 dollars
Step-by-step explanation:
they give you the equation already of E(h) = 10h with h being hours. So, if she tutors for 3 hours then 10(3) would equal 30 dollars.
1. Expand by distributing terms.
5x times 3 + 5x times -7y
2. Simplify 5x times 3 to 15x.
15x + 5x times -7y
3. Simplify 5x times -7y to -35xy.
15x - 35xy
Then you’re done. Hopefully this helps.
10% of 10 is 10%*10 which is 1 :)
