Can u me in number 23 i don’t know how to do this

This is an example of systems of equations, using weird symbols rather than x or y.

We'll substitute the symbols for the variables d and c

d for diamond, c for clover.

3 + d = c

c + d = 11

We can solve for one variable in the first equation to find the true value of the other variable in the second equation.

3 + d = c

Subtract 3 from both sides.

d = c - 3

Now we have a value for d and can solve the second equation.

c + d = 11

Substitute.

c + c - 3 = 11

Add 3 to both sides.

c + c = 14

Combine like terms.

2c = 14

Divide both sides by 2.

c = 7

Now we know the absolute value of c and can solve for the value of d.

d + c = 11

d + 7 = 11

Subtract 7 from both sides.

d = 4

The diamond, or d, is equal to 4. And the clover, or c, is equal to 7. (This is your answer.)

Let me know if you have any questions.

the correct answer is semicircle

step-by-step explanation:

the answer is semicircle because the shorter arc joining two points on the circumference of a circle is known as the minor arc, the larger arc is called the major arc, and a semicircle is a half circle, formed by cutting a whole circle along a diameter line.

hope i .

2nd one in the first row is correct
