11x + 12(11x + 1) = 12
11x + 132x + 12 = 12
143x = 0
x = 0
y = 11x + 1
y = 11(0) + 1
y = 1 <==
Answer:
4
Step-by-step explanation:
If you have a scientific calculator you can easily plug this into the calculator and get the answer: Below I will show you the steps to get the answer
1. (distribute the - sign to the number 2)
2. (Multiply -2 and -1)) (also subtract 3-1)
3. (Multiple -2 * -2 * -2) ( multiple 2*2)
4.
5. 4
6 + (10 x 2) = 26 = (12+1)*2
Answer:
A knife costs £2.88.
Step-by-step explanation:
Create two equations using what you know to show the problem.
k = 2s
12k + 8s = 46.08
Substitute the first equation in for k, then isolate s to find how much spoons cost.
12(2s) + 8s = 46.08
24s + 8s = 46.08
32s = 46.08
s = 1.44
A spoon costs £1.44. To find the price of a knife, double the cost of a spoon:
1.44 * 2 = 2.88
A knife costs £2.88.
Answer:
29 feet above sea level
Step-by-step explanation:
One floor is 9 feet high, so the top of the first floor will be 9 feet above the ground.
The ground is also 20 feet above sea level, so add 9 to this to find how many feet above sea level the top of the first floor is:
20 + 9
= 29 feet above sea level
