Step-by-step explanation:
(a)
10x - 45 ← factor out 10 from each term
= 10(x - 4.5)
(b)
- 2x + 3 ← factor out - 2 from each term
= - 2(x - 1.5)
(c)
- x + 4 ← factor out - 1 from each term
= - 1(x - 4)
(d)
- x - 19 ← factor out - 1 from each term
= - 1(x + 19)
310y=2y^2+xy. This is the answer
Answer:
15
Step-by-step explanation:
because it's is 15 and you can add 15 5 times n get 75
Answer:
370 millimeters of compound B is needed for 666 millimeters of solution.
Step-by-step explanation:
Given that:
4 millimeters of compound A are used for every 5 millimeters of compound B.
The scientist wants to make 666 millimeters of solution.
Let,
x be the multiplier number of the compounds in the solution.
Then,
4x + 5x = 666
9x = 666
Dividing both sides by 9
Millimeters of compound B = 5x = 5(74) = 370 millimeters
Hence,
370 millimeters of compound B is needed for 666 millimeters of solution.
