Let the sides lengths of the triangle be a, band c respectively

given ,

a= 8

b= 10

c = 12

To find : perimeter of the triangle = ?

We know ,

Perimeter of triangle = a+b+c

Write the ratio in fractional notation in lowest terms. 28 inches to 42 inches
ivolga24 [154]

28 to 42 means 28/42

We now reduce 28/42 to lowest terms.

28 ÷ 7 = 4

42 ÷ 7 = 6

We now have 4/6.

We now reduce 4/6.

4 ÷ 2 = 2

6 ÷ 2 = 3

Final answer: 2/3

Can someone help me please
Mademuasel [1]
So first of all, both angles are alternate interior angles right. so they would equal the same thing. all you have to do is divide 75 by 3 to get the x which would equal 25. Hope that helps :)

Plz help with slope question
nasty-shy [4]

Answer:

The equation in slope-intercept form:

y = -3x - 4

Step-by-step explanation:

Use the point-slope formula:

y-y_{1} = m (x-x_{1})

Use the given slope -3 and point (0,-4) for the formula:

y + 4= -3 (x-0)

-Then, you solve the formula:

y + 4 = -3 (x-0)

y+4 - 4 = -3 (x-0) -4

y = -3x - 4

The equation, which is in slope-intercept form:

y = -3x - 4

A waitress sold 12 ribeye steak dinners and 39 grilled salmon totaling $575.53 on a particular day. Another day she sold 25 ribe
Talja [164]

Answer:

cost of ribeye steak dinners = $10.36

cost of grilled salmon= $11.581

Step-by-step explanation:

Let the cost of one steak dinners be x

Let the cost of one  grilled salmon be y

One a particular day the waitress sells  12 ribeye steak dinners and 39 grilled salmon for a total is $575.53 which can be written in equation as

12(x)+39(y)= $575.53-------------------------------------(1)

On another day she sells  25 ribeye steak dinners and 13 grilled salmon dinners  totals to $582.43.This can be represented  as

25(x)+ 13(y)= $582.43-------------------------------------(2)

solving the equation (1) and (2)

eq(1) x 112x+39y= 575.53

eq(2) x 3125x+ 39y= 1747.29-------------------------(3)

Subtracting these equation we get,

113x=1171.76

x=\frac{1171.76}{113}

x= 10.36

Now  substituting this in equation (1)

12(10.36)+39(y)= $575.53

123.84+39y=575.53

39y=575.53 - 123.84

y=\frac{451.69}{39}

y=11.581
