The missing number is 23 because,
there is 3 feet in 1 yard
so, 7x3=21
21+2=23
so 7 yards and 2 feet = 23 feet
There are three friends and 4 cups. Each friend can have a whole cup each and need to split the last cup 3 ways (1/3)
Each friend would get 1 cup and 1/3 of a cup
(I hope I’m right~)
Answer:
(0, 4 ) and (2, - 4 )
Step-by-step explanation:
(2)
3x + 4y = 16 → (1)
- 3x + 2y = 8 → (2)
Adding (1) and (2) term by term will eliminate the x- term
0 + 6y = 24
6y = 24 ( divide both sides by 6 )
y = 4
Substitute y = 4 into either of the 2 equations and solve for x
Substituting into (1)
3x + 4(4) = 16
3x + 16 = 16 ( subtract 16 from both sides )
3x = 0 , then
x = 0
solution is (0, 4 )
(3)
2x - 4y = 20 → (1)
5x + 4y = - 6 → (2)
Adding (1) and (2) term by term will eliminate the y- term
7x + 0 = 14
7x = 14 ( divide both sides by 7 )
x = 2
Substitute x = 2 into either of the 2 equations and solve for y
Substituting into (2)
5(2) + 4y = - 6
10 + 4y = - 6 ( subtract 10 from both sides )
4y = - 16 ( divide both sides by 4 )
y = - 4
solution is (2, - 4 )
The answer is the third option.
The solution is in the pdf file attached. Please, let me know if you can follow the steps.
Answer:
If numbers divisible by 6 are also divisible by 3 then any thing times 6 will be the same by 3.
