7/8, One should first make all the fractions have the same denominator so 3/8 and 1/2=4/8 so then add 3/8+4/8=7/8
1 and 3 have the same angle and 2 and 4 have the same angle. Since we know what 1 is we know what 3 is, add them together then subtract that from 360 = 148. To figure out the angles of 2 and 4 divide 148 by 2 = 74. 1 and 3 are 106 degrees and 2 and 4 are 74 degrees :)
2 x 4y = 12.4
4y = 6.2
y = 6.2/4
= 1.55
hope this helps
Answer:
Addition
Step-by-step explanation:
The first step in solving 4x-3=5 is to add 3 to both sides. This demonstrates the addition property of equality, since adding a number to both sides of an equation balances it.
