4,000,000 + 8,000 + 110 + 6 + (9/10) + (5/100)
=4,008,116.00+0.90+0.05
=4,008,116.95
Answer:
a : b : c = 12 : 10 : 15
Step-by-step explanation:
Given that: b = of c
i.e b = ............... 1
2c = 5b
So that;
c = .................... 2
Also,
4a = 3c
a = ................ 3
⇒ a = × ()
a = ................. 4
15b = 8a
b = ................. 5
Comparing the derived equations:
From equations 2 and 3,
a:c = : = 4:5
From equations 1 and 2,
b:c = : = 2:3
But a common value of b = 15, gives;
a : c = 12 : 15 and b : c = 10 : 15
Thus, a : b : c = 12 : 10 : 15
The equation you had:
6x + 5y = 45
Solve for Y:
5y = (-6x) + 45 divide by 5
y = (-6/5)x + 9
y = -1 1/5x +9
Answer:
(5x + 3)² + 3
Step-by-step explanation:
25x² + 30x + 12 =
= (25x² + 30x) + 12
How do we make 25x² + 30x into a perfect square?
25x² is the square of 5x, so our binomial that is squared will start with
(5x + ___)²
We need to find the number that is added to 5x inside the parentheses.
The middle term of the squared binomial is 2 times the first term times the second term.
2(5x)b = 30x
b = 3
The binomial is (5x + 3).
When we square it, the last term will be 9. We need to add 9 to 25x² + 30x to have a perfect square. Then we also need to subtract 9 to not change the value of the expression.
= (25x² + 30x + 9) + 12 - 9
= (5x + 3)² + 3
