The polygons are said to be similar if and only if the ratio of the measures of their corresponding sides are equal. If we are to establish the equation by the definition given above that would be,
15/10 = 60/x
The value of x from the equation is 40. Hence, the side measures 40.
ANSWER: 40
The answer is the last choice.
Answer:
i think it would be $80 (brainliest??)
Step-by-step explanation:
jane had a total of $200 BEFORE she spent on 2 games
1. $40
2. $40
3. $40
4. $40
5.$40
2 games = $80
3 games = $120 (money she had left)
A = l × w. Substitute 72 into A and fill in the rest of the equation.
w = l - 1. Plug l - 1 into w
72 = l × (l - 1). Multiply l by (l - 1)
72 = l^2 - l. Subtract 72 from each side.
0 = l^2 - l - 72. Factor.
0 = (l + 8) (l - 9). Set each term equal to zero.
(l + 8) = 0. Subtract 8 from each side.
l = -8. Length cant be a negative number so let's try the other term.
(l - 9) = 0. Add 9 to each side.
l = 9. The length is 9.
Earlier we stated that the width is one less than the length, therefore, the width is 9 - 1 = 8.
The width is 8 units.
Answer:
x= 226/3 or 75.33333333333333333333333333333
Step-by-step explanation:
14y+82=6x-20
y=25
Sub y=25 into 14y+82=6x-20
14y+82=6x-20
14(25)+82=6x-20
Calculate as follows:
14(25)+82=6x-20
350+82=6x-20
432=6x-20
Add twenty to both sides:
432+20=6x-20+20
452=6x-0
452=6x
Divide both sides by 6
452=6x
452/6=6x/6
452/6=x
x= 226/3 or 75.33333333333333333333333333333
