So we don't know both of their age but we do know that Jessica is 4 year younger so let make x stand for Jennifer age and n is for jessica so our equation needs to be n + 10 = 8 + 2n subtract n from both sides so now we have 10 = 8 + n then subtract 8 from both sides so now we have 10 - 8 = n so jessica is 2 but now we need to find Jennifer age by adding 4 to 2 = 6
jessica is 2 and Jennifer is 6
Answer:
4/b
Step-by-step explanation:
7/b - 3/b
Since the denominators are the same, we can subtract
4/b
Answer:
Step-by-step explanation:
(29, 35) (43, 21)
(21 - 35)/(43 - 29) = -14/14 = -1
y - 35 = -(x - 29)
y - 35 = -x + 29
y = -x + 64
Answer:
x = 12
Step-by-step explanation:
The mistake made here is in making 130 = 9x + 7. They are not the same.
The central angle = 130 degrees.
Any angle sharing the endpoints of the central angle and having it's vertex on the same side of the central angle is 1/2 the central angle.
1/2 the central angle = 130 /2 = 65
Cyclic quadrilaterals (those with all 4 points touching a circle's circumference) have opposite angles supplementary.
65 + 9x + 7 = 180 Combine like terms on the left
72 + 9x = 180 Subtract 72 from both sides
72 - 72 + 9x = 180-72 Combine
9x = 108 Divide by 9
9x/9 = 108/9
x = 12
Answer:
85
Step-by-step explanation:
The line of the right measures 65 degrees (I think), an the line on the left measures 150 degrees. So, 150 - 65 = 85 degrees.
