Answer:
x = 65 , y = 64
Step-by-step explanation:
y - 16 and 2y + 4 are same- side interior angles and sum to 180° , that is
y - 16 + 2y + 4 = 180
3y - 12 = 180 ( add 12 to both sides )
3y = 192 ( divide both sides by 3 )
y = 64
then
2y + 4 = 2(64) + 4 = 128 + 4 = 132
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
2y + 4 is an exterior angle of the triangle , then
x + 67 = 132 ( subtract 67 from both sides )
x = 65
Answer:
p =2 p=-18
Step-by-step explanation:
|p+8|
-------------- = 5
2
Multiply each side by 2
|p+8|
-------------*2 = 5*2
2
|p+8| =10
There is a positive and a negative solution
p+8=10 p+8=-10
Subtract 8 from each side
p+8-8=10-8 p+8-8=-10-8
p =2 p=-18
compare the divisor x-3 with x-a which will give a=3 and then use remainder theorem.
Answer:
Answer is 49
Step-by-step explanation:
Add all the ratios up you get 21 so then you divide 147 by 21 thus giving you 1 ratio = 7 respectively, and we know the ratio of the red is 7 because it's stated red, blue, and green -> 7,6,8. So then 7 * 7 = 49. And to confirm you can do (7*7)+(6*7)+(8*7) which should equal 147
Answer:
7 : 15 : 9
Step-by-step explanation:
The GCF is 8:
56/8 = 7
120/8 = 15
72/8 = 9
