Tju [1.3M]

Answer: 35

Step-by-step explanation:

Given : At Deb’s Deli, a customer may choose either a sandwich and a salad or a sandwich and a soup for the lunch special.

The number of choices for sandwiches = 5

The number of choices for salad = 4

The number of choices for soup = 3

Now, the number of possible lunch special combinations can be ordered will be :-

$5\times4+5\times3=20+15=35$

Hence, the number of possible lunch special combinations can be ordered will be 35.

Show that x + y : x - y= 3 : 2

insens350 [35]

Answer:

x + y : x - y = (5/2+1/2) : (5/2-1/2)

x + y : x - y = 3 : 2

Therefore, x + y : x - y= 3 : 2 is proved.

Step-by-step explanation:

Given

x + y : x - y = 3 : 2

As

$x + y = 3$

$x - y = 2$

Solving to find x and y

$\begin{bmatrix}x+y=3\\ x-y=2\end{bmatrix}$

$x-y=2$

$-$

$\underline{x+y=3}$

$-2y=-1$

$\begin{bmatrix}x+y=3\\ -2y=-1\end{bmatrix}$

solve for y

$-2y=-1$

Divide both sides by 2

$\frac{-2y}{-2}=\frac{-1}{-2}$

$y=\frac{1}{2}$

$\mathrm{For\:}x+y=3\mathrm{\:plug\:in\:}y=\frac{1}{2}$

$x+\frac{1}{2}=3$

$x+\frac{1}{2}-\frac{1}{2}=3-\frac{1}{2}$

$x=\frac{5}{2}$

so

$x=\frac{5}{2},\:y=\frac{1}{2}$

Thus,

x + y : x - y = (5/2+1/2) : (5/2-1/2)

x + y : x - y = 3 : 2

Therefore, x + y : x - y= 3 : 2 is proved.

Find the values of a, b and c.

shusha [124]

C= 45
All interior angles of a triangle add to 180. 90+45=135. 180-35=45

a= 45
The top angle of the triangle and a make 90 degrees together. 90-45=45

b= 135
Angle a and b together make 180 (they are supplementary). 180-45=135

3+5x=38
-3 on both sides
5x=35
divide by 5 on both sides
