Let Tory’s sister age = x
Since Tory is 3 years older than her sister ,
Tory = (x + 3)
let Quentin’s brother age = x
( because quentin’s brother & tory’s sister are the same age , we can let both their ages be x )
Since Quentin is 8 years less than twice his brother’s age ,
Quentin = (2x -8)
Since Quentin and Tory are the same age ,
x + 3 = 2x - 8
-x = -8-3
x = 11
Ans : 11 years old :)
I’m so sorry if this is incorrect
The area is 11.7 ft^2
good luck
If we let x be the greater integer, then the lesser integer can be represented by the expression, x - 2. The equation that would best represent the given scenario is,
(x)(x - 2) = 143
Solving for x in this equation will give us an answer of 13.
x = 13
x - 2 = 11
Thus, the greater integer is 13.
Answer:
x = 4
y = 4
Step-by-step explanation:
the front triangle has two 40° angles (sum of all ∡'s must be 180°)
the unlabeled lower-left angle then is 40°; this angle corresponds to the angle in the other triangle labeled as 10y°
therefore, 10y = 40 so y = 4
Since opposite angles in a parallelogram are congruent then we can write:
40° + 25x° = 100° + 10(4)°
25x° = 140 - 40°
25x = 100°
x = 4
