Answer:

A) x+y=4

B) x-y=-6

We add both equations and get

2x = -2 so x = -1

and y = 5

So the ordered pair (-1, 5) is the solution to the equations.

-1+5=4
And
-5+1=-4
So it’s x+y=4

Q1.

Angle BAD is adjacent to angle CAD

which means they are equal

so angle BAD = 26 degrees

Q2.

Angel BAC = the sum of angles BAD and CAD

because they are adjacent angles

To find the angles we solve the equations

9x-5 = 3x+7

9x-3x = 7+5

6x = 12

x = 12/6

x = 6

From 1/4 cups of sugar she can make mini apples for 12 batches.

<h3>What is a numerical expression?</h3>

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, 1/2 cup of sugar is needed to make a mini apple for 24 batches.

∴ From (1/2)×(1/2) = 1/4 cup of sugar is needed to make a mini apple for 24×1/2 = 12 batches.
