Solve this problem by subtracting 1/4 from 2 1/2. 

2 1/2 - 1/4 = 2 2/8 = 2 1/4 pounds of blueberries left. 

Now subract how many are left from the original amount. 

2 1/2 - 2 1/4 = 2/8 = 1/4 lb. 

Your answer should be 1/4 lb.

makvit [3.9K]
Let j = cost of one jumbo popcorn, and c = cost of one chocolate chip cookie.

Then, based upon the given info, 1j + 2c = $5.

Also, 3j + 5c = $14.50

Let's solve this system of equations using addition/subtraction:

Mult. the first equation by -3, to obtain   -3j - 6c = -$15

Now add this result to the 2nd equation:   

-3j - 6c = -$15
3j + 5c = $14.50
----------------------
     -c = -$0.50, or c = $0.50.       Since   3j + 5c = $14.50, subst. $0.50 for c 
lets us find j:

3j + 5($0.50) = $14.50, so 3j = $12.00.  Thus, j = $4.00.


Jumbo popcorn is $4/bag, and choc. chip cookies $0.50 each.

1. What is the value of h? (1 point)
irinina [24]

The value of h is 11.3.

Solution:

Given data:

The triangle is a right triangle.

θ = 45° and opposite side of θ = 8

The value of sin 45° = \frac{1}{\sqrt{2} }

Using trigonometric formula,

$\sin\theta=\frac{\text{Opposite side}}{\text{Hypotenuse}}

$\sin45^\circ=\frac{{8}}{h}

$\frac{1}{\sqrt{2} } =\frac{{8}}{h}

Do cross multiplication.

h = 8\sqrt 2

h = 11.3

The value of h is 11.3.

katovenus [111]

The equation is 2.5x + 2y - 2 = 0.

<h2>Linear system</h2>

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

Given

He bought 2.5 pounds of apples that are x dollars a pound.

And 2 bags of lettuce for y dollars each.

The total cost is $2.

<h3>To find </h3>

The equation of this.

<h3>How to find the equation?</h3>

He bought 2.5 pounds of apples that are x dollars a pound.

Then the expression is 2.5x

And 2 bags of lettuce for y dollars each.

Then the expression is 2y

The total cost is $2.

Then the expression will be

    2.5x + 2y = 2

2.5x + 2y - 2 = 0

Thus the equation is 2.5x + 2y - 2 = 0.
