Answer:7x+3=59
59-3
7x=56
Then you divide them both by 7
7x/7=56/7
Then you get your answer
X=?
I'll let you do the last part tho
Step-by-step explanation:
The answer is (1,4) plug it in to check if you want
K² + 13k + 30 = 0
This is a quadratic equation. Let's attempt solving it by factorization.
Coefficient of k² = 1, last term = 30
Multiply these two together 1*30 = 30
We think of two numbers that multiply to give 30 and add to give the middle term 13.
The two numbers are 3 and 10.
3*10 = 30, 3 + 10 = 13.
we replace the 13k with 3k + 10k
k² + 13k + 30 = 0
k² + 3k + 10k + 30 = 0
k(k + 3) + 10(k + 3) = 0
(k + 3)(k + 10) = 0
(k + 3) = 0 or (k + 10) = 0
k = 0 - 3 or k = 0 - 10
k = -3, or -10
I hope this helps.

Answer:
- 5 containers
- 1/3 pound left over
Step-by-step explanation:
The amount Victoria needs is ...
(1/3 lb/burger) × 14 burgers = (1/3)(14) lb = 4 2/3 lb
The next higher multiple of 1 lb is 5 lb.
Victoria needs to buy 5 containers of tofu. There will be 1/3 lb left over.
3x = 11 -2
3x = 9
x = 3
just make X the subject of the formula and you will get to ur final answer. Easy.
