So WX is 7y +4 and XY is 21, and when you add those lines you get the whole thing, which is 12y so write that like an equation
12y = 7y+4+21
12y = 7y+25
5y = 25
y = 5
49 degree is the answer
tanø = 46/40
= 1.15
Ø = 49 degree
12/5 - 3/10 = 24-3 /10 = 21/10
OR 2.1 in decimal form
Answer:
Cans for food drive
Step-by-step explanation:
A variable is a letter, for example x, y or z, that represents an unspecified number.
6 + x = 12
To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12.
