Answer:
80
Step-by-step explanation:
The three angles of a triangle add to 180 degrees. One angle is 10, the second is a right angle( which is 90 degrees). Let the third angle be x
10 +90 +x = 180
Combine like terms
100 +x =180
Subtract 100 from each side
100-100 +x= 180-100
x = 80
Total socks = 4 + 7+ 11 = 22
Red = 4
White = 7
P(red, then white) = (4/22)(7/21) = 2/33
Answer: 2/33
Answer:
Gabe worked 65, Abe worked 62 and Babe worked 69.
Step-by-step explanation:
Let Gabe = x
Therefore, Abe worked: x-3 and Babe worked x+4
So,
x+(x-3)+(x+4)=196
3*x+1=196
3*x=195
x=65
Then,
x-3= 62
x+4=69
Answer:
18=x*.20
15=x*.25
12=x*.30
24=x*.40
39=x*.60
78=x*.30
Step-by-step explanation:
To solve for x on each, divide the number on the left of the equal side by the number x is being multiplied by. For example, 18/.20=x
2:3
6 ÷ 2 = $3 (cost of 1 pack of butter cookies)
3 x 3 = 9 (cost of 3 packs of butter cookies)
17 - 9 = 8 (cost of 4 packs of chocolate cookies)
8 ÷ 4 = 2 (cost of one pack of chocolate cookies)
