Bc = 24
Ad = 5y-1
5 times what is 25?
5 x 5 = 25
25 - 1 = 24
Therefore Y = 5
5(5) - 1 = 24
Divide the 10 cent coin by the 50 cent coin :)
Answer:
B
Step-by-step explanation:
7x + 1 isn't equal to 8x
For example:
Addition. In this equation, you can add all of the coefficients (2, 5, and 4) because the variables are the same (a).
2a + 5a + 4a = 11a
Subtraction. In this equation, you can subtract all of the coefficients (11, 5, and 4) because the variables are the same (a).
11a – 5a – 4a = 2a
Answer:
B
Step-by-step explanation:
Given the 2 equations
3x - 2y = 6 → (1)
5x + 4y = 32 → (2)
Multiplying (1) by 2 and adding to (2) will eliminate the y- term
6x - 4y = 12 → (3)
Add (2) and (3) term by term to eliminate y
11x = 44 ( divide both sides by 11 )
x = 4
Substitute x = 4 into either of the 2 equations and solve for y
Substituting into (2)
5(4) + 4y = 32
20 + 4y = 32 ( subtract 20 from both sides )
4y = 12 ( divide both sides by 4 )
y = 3
Solution is (4, 3 ) → B
