What is the value of the expression below when w = 8 and x = 4? 9w + 5x
Ne4ueva [31]

Answer:

92

Step-by-step explanation:

If w=8 then you would multiply 9 by 8 which is 72. Then you would multiply 5 with 4 since x equals 4 which is 20. Then you would add 72+20 which gives you your answer which is 92

Please help I’m struggling on this topic
wel
Answer: x=36
explanation: in the corner of (2x+18)°, it would be 90° as it is a right angle, 90-18=72 72/2=36, putting it into the equation 2(36)+18=90°. for (3x+6), putting 36 as x 3(36)+6=114° since every 3-sided triangle and a line with another line crossing through has angles that add up to 120°, if you add up 90 and 24 you get 114°, 120-114=6. if you add 6 to the 114° from the (3x+6)° equation you also get 120°, therefore x=36

Calculate the unknown angles
Setler79 [48]

Answer:

see explanation

Step-by-step explanation:

Since the 2 lines are parallel, then

d = 55° ( corresponding angles are congruent )

e = 55° (vertical to d and congruent )

e and f are same side interior angles and are supplementary, thus

e + f = 180°, that is

55° + f = 180° ( subtract 55° from both sides )

f = 125°

c = 125° ( alternate to f and congruent )

Hence

c = 125°, d = 55°, e = 55°, f = 125°
