Set up a ratio and solve for the missing value:

\frac{27}{3} =\frac{x}{5}\\x = \frac{(27)(5)}{3}\\x = 45


The couple rested for 45 minutes in 5 hours.

Solve for the values of x and y in the diagram
qaws [65]

Answer: y = 0.5, x = 50

Step-by-step explanation: Both triangles in the picture are isosceles, telling us that the 2 angles at the bottom are congruent. With this, we can find y by doing the following:

a triangle has 180 degrees so we subtract the given 50 which gives us 130

2(2y + 64) = 130

4y + 128 = 130

y = .5

This means that the bottom 2 angles are both 65. Since the top angle of the second triangle is supplementary to the bottom angle of the first one, the top angle of the second triangle is 115. So, we find x by:

2(45 - x/4) = 65

x = 50

This means the bottom 2 angles of the second triangle are both 32.5.

Write an equation in slope-intercept form of the line shown. (-4,0) and (1,-5)
Irina18 [472]

The slope intercept form is y = -x - 4

To find the slope intercept form given a couple of points, start by finding the slope using the slope equation.

m(slope) = (y2 - y1)/(x2 - x1)

m = (-5 - 0)/(1 - -4)

m = -5/5

m = -1

Now we look for the intercept using slope intercept form, our slope and a point.

y = mx + b

0 = -4(-1) + b

0 = 4 + b

-4 = b

Now we can use those two things top model the equation.

y = -x - 4

A 16-ounce package of frozen vegetables costs $2.10. How much would you expect a 12-ounce package to cost?
statuscvo [17]
Hi!

We need to find the cost per ounce. 
2.10/16 = 0.13125

It costs 0.13125 per ounce. 

Now find the cost of 12 ounces. 
12 * 0.13125 = $1.58

The answer is $1.58

Hope this helps! :)
