Answer:
1) -8h and 4h
2) 3t and 7t
3) -4e and 3e
4) -2b and b
Step-by-step explanation:
They all have the same variable as the other in the pair. There aren't any other variables added or exponents.
You just take the number and for each whole number, that's 100 % if there is decimals, you take while percent . tens. hundreads....
Answer:
B and D
Step-by-step explanation:
3*(5²)-42=33
75-42=33
3*((-5)²)-42=33
75-42=33
Answer: 95°
Step-by-step explanation: We are given information for Angles 1 and 4, which happen to be vertical angles, meaning they are congruent. Because of this, we can say 3x+10=4x-15, therefore x=25. Angles 1,2,3 and 4 must add up to 360°, and since we know angles 1 and 4 are 85° (3*25 + 10 = 85), we can find angles 2 and 3. 360° - 85° - 85° = Angle 2 + Angle 3. Angle 2 + Angle 3 = 190, and because Angles 2 and 3 are vertical angles and therefore congruent, we can divide 190 by 2 and get that Angles 2 and 3 equal 95°. Because lines b and c are parallel, any corresponding angles created by a transversal are congruent. This basically means Angles 3 and 7 must be congruent, therefore Angle 7 = 95°
Congruent - same meaning as equal
Vertical Angles - each of the pairs of opposite angles made by two intersecting lines.
