Answer:
(7, - 7 )
Step-by-step explanation:
- 4x + y = - 35 → (1)
- 2x - y = - 7 → (2)
adding the 2 equations term by term will eliminate the y- term
(- 4x - 2x) + (y - y) = - 35 - 7
- 6x + 0 = - 42
- 6x = - 42 ( divide both sides by - 6 )
x = 7
substitute x = 7 into either of the 2 equations and solve for y
substituting into (1)
- 4(7) + y = - 35
- 28 + y = - 35 ( add 28 to both sides )
y = - 7
solution is (7, - 7 )
Answer:
10%
Step-by-step explanation:
firstly express as a fraction then multiply the fraction by 100% , that is
× 100% = 2 × 5 = 10% of the flowers are roses
Answer:
(6*10)/5
= 60/5
= 12
Step-by-step explanation:
Factor : 8y - 36
Go through all of the answer choices & see which one is correct.
a) -4 (2y + 9)
You don't even have to fully simplify this, just by looking at the -4, you already know that this is incorrect because you need to have a positive 8. So, A is incorrect.
b) 8 (y - 4)
Simplify.
8y - 32
Incorrect because it is not equal to the original equation.
c) 2 (4y - 18)
Simplify.
8y - 36
Correct answer because it is equal to the original equation.
d) 4(2y - 9)
Simplify.
8y - 36
D is also correct.
So, your answer is : (C) and (D) are your answers.
