Step-by-step explanation:
__ + __ + __ = __ fill in the blanks
if 60, 80, and y have a sum of 180, the equation is 60+80+x=180
Answer:
It can be either one, if you prefer reading you can ask questions through text, if you prefer talking verbally then I'd say over video is best.
Answer:
70° is the answer hope it helps
30°+90°+ 3y= 180°
120°+3y= 180°
3y= 180°-120°
y= 60°/3
y= 20°
Now
y°+90°+x°= 180°
20°+90°+x= 180°
x= 180°-110°
x= 70°
Answer: She had 200 cards to start with
Step-by-step explanation:
Let x = the amount of cards she had initially. This means she had x cards to start with.
She gave half of the cards she had to a friend. This means she gave her friend x/2 cards. She is left with with (x-x/2) = x/2 cards.
She also gave 1/4 of the remaining cards to her brother. This means that she gave (1/4 × x/2) = x/8 cards to her brother.
Remaining number of cards will be x/2 - x/8 = (4x-x)/8 = 3x/8
She still has 75 cards left. This means
3x/8 = 75
Cross multiplying with 8, it becomes
3x = 75×8 = 600
x = 600/3 = 200
She had 200 cards to start with.
