It looks like it’s already in order, first you subtract the x in the right so it’s 6x, then subtract 4 from 10 so 6 and then divide by 6

Chanel‌ ‌has‌ ‌two‌ ‌dogs,‌ ‌Mimi‌ ‌and‌ ‌Honey.‌ ‌

tresset_1 [31]

Start off calculating the total of the dog food Mimi and Honey eat together every day. Knowing 1/2 and 2/4 is the same it might help while adding up those numbers. That means they eat 3/4 + 2/4 = 1 1/4 can everyday. Multiply that by the total days, in this case 60, gives you 75 cans. You can only buy a 3-pack so dividing it by 3 gives you the total of packs she has to buy. That is in this case 25 packs. While every pack costs you $5 that means 25 packs will cost Chanel 25 x $5 = $125. Doing the same but for 29, 30 and 31 days instead of 60 should give you the answer to the last few questions.

Jenny and Kath hire the canal boat for 14 days. They share the hire cost of £1785.00 in the ratio 2:3. Work out the smaller shar

Dafna1 [17]

Answer:

£714.00

Step-by-step explanation:

The first step is to set up expresssions for the two shares:

Let x = the amount of one share. The other share is 1785 - x. You don't have to worry about which is smaller--that part will work out automatically!

The two shares are in the ratio of 2:3, so set up the proportion

$\frac{x}{1785-x}=\frac{2}{3}$

Again, you don't have to worry--you could set up the proportion "upside down" and everything will work out in the end.

Solve the proportion for x by "cross multiplying" -- use the Means-Extremes Property of proportions.

$(3)(x)=(2)(1785-x)\\3x=3570-2x\\5x=3570\\x=714$

So one share is £714£ and the other is £1785 - £714 = £1071.

The smaller share is £714.

Consider the parabola given by the equation: f(x) = 4x² - 6x - 8 Find the following for this parabola: A) The vertex: Preview B)

jeyben [28]

Answer:

The vertex: $(\frac{3}{4},-\frac{41}{4} )$

The vertical intercept is: $y=-8$

The coordinates of the two intercepts of the parabola are $(\frac{3+\sqrt{41} }{4} , 0)$ and $(\frac{3-\sqrt{41} }{4} , 0)$

Step-by-step explanation:

To find the vertex of the parabola $4x^2-6x-8$ you need to:

1. Find the coefficients a, b, and c of the parabola equation

$a=4, b=-6, \:and \:c=-8$

2. You can apply this formula to find x-coordinate of the vertex

$x=-\frac{b}{2a}$ , so

$x=-\frac{-6}{2\cdot 4}\\x=\frac{3}{4}$

3. To find the y-coordinate of the vertex you use the parabola equation and x-coordinate of the vertex ( $f(-\frac{b}{2a})=a(-\frac{b}{2a})^2+b(-\frac{b}{2a})+c$ )
