Answer:

260 stickers

Step-by-step explanation:

Let Gareth's stickers be x.

Hence Cheryl sticker is 160+x;

If Cheryl gave 185 stickers

to Gareth, it means:

Cheryl has at the moment;

160 + x - 185 = x - 25

At this time when Gareth receives 185 he now has:

x+ 185

Also when he receives x +185, he has 3 times Cherry's meaning:

x+185 =3(x-25)

x + 185 = 3x -75

185 + 75 = 3x-2x

260= x

x = 260.

Hence Gareth has 260 stickers

Official unemployment rates for the U.S. population are reported on a monthly basis by the Bureau of Labor Statistics. For the p

Kitty [74]

Step-by-step explanation:

Clearly, there is a common difference between the monthly employment rates:

8.7% - 8.9% = -0.2%

8.5% - 8.7% = -0.2%

8.3% - 8.5% = -0.2%

a) So, for every month x, the percentage will go down 0.2%, starting at 8.9%. So, we can make this equation:

y = -0.2x + 9.1, where x = 1 would be October 2011.

January 2013 is 16 months after October 2011, so:

y = -0.2(16) + 9.1

y = 5.9%

b) To find when the unemployment rate will be zero, we set the equation equal to zero:

0 = -0.2x + 9.1

-0.2x = -9.1

x = 45.5 months

So, rounding up, the U.S. would reach a zero unemployment rate in 46 months or around September 2014? Not completely sure.

Which expression is equivalent to x^4 + 4x^2 - 45?

Nikitich [7]

Answer:

$( {x}^{2} - 5)( {x}^{2} + 9) = 0$

Step-by-step explanation:

The given expresion is

${x}^{4} + 4 {x}^{2} - 45 = 0$

We can rewrite this as:

$({ {x}^{2}) }^{2} + 4 {x}^{2} - 45 = 0$

We obtained a quadratic equation in x²

Let us split the middle term to get:

$({ {x}^{2}) }^{2} + 9 {x}^{2} - 5{x}^{2} - 45 = 0$

We factor by grouping to get:

${x}^{2} ( {x}^{2} + 9) - 5( {x}^{2} + 9) = 0$

We factor further to get:

$( {x}^{2} - 5)( {x}^{2} + 9) = 0$

The correct answer is A.

loris [4]

Answer:

1.75

Step-by-step explanation

Perhaps, 1 7/8 is a bit of an Improper fraction, therefore Multiply the side number of this Improper fraction (1x7) Witch will give you 7/8 times that against 2 and you will get 1.75. (Forget the last period by the number.)
