We are given proportion as 14/x = 1/2
So first step is to get rid off 2 from denominator,so we multipy both sides by 2
2(14/x) =2(1/2)
28/x =1
Next step is to get rid off x from denominator ,so we multiply both sides of the equation by x
x(28/x) =x(1)
28x/x =x
28 =x
Hence we get value of x =28
So answer is choice d) 28
Answer:
40
Step-by-step explanation:
h(x)= 4(x + 6)
Let x=4
h(4)= 4(4 + 6)
= 4(10)
= 40
Answer:
b) 3
Step-by-step explanation:
4.5+1.5x=18-3x
1) Subtract 4.5 from both sides:
1.5x=13.5-3x
2) Add 3x to both sides:
4.5x=13.5
3) Divide both sides by 4.5:
x=3
Let's start by grouping like terms so we can factor out the most
(4x^4+24x^3)+(12x^2+8x)
now let's factor out as much as possible. we see all coefficients are multiples of 4, we will also factor out as high a degree of x as we can
4x^3(x+6)+4x(3x+2)
now we see that we still have a common multiple of 4x that we can remove
4x(x^2(x+6)+(3x+2))
so we find 4x is the largest value we can factor out
Answer:
6.65
Step-by-step explanation:
7- 0.35 = 7.00- 0.35 = 6.65
