Answer:
x=8
Step-by-step explanation:
Those angles are supplementary so:
140+5x=180
5x=40
x=8
Answer:
4 t - 7 = 2 t+ 13 is the required equation.
The number of race medals Tara has is t = 20 medals.
Step-by-step explanation:
Let the number of medals Tara has = t medals
So, the number of medal Anita has = 4( Medals of Tara) - 7
= 4t - 7
And the number of medals Gary has = 2 times (Medals of Tara) + 13
= 2(t) + 13 = 2t + 13
Now, Annita and Gary has same number of medals.
⇒ 4t - 7 = 2t+ 13
or, 4t - 2t = 7 + 13
⇒ 2t = 20
⇒ t = 20/2 = 10
or t = 10
Hence, the number of race medals Tara has is t = 20 medals
Since you keep proportional dimensions, the proportion between the old and new dimensions must be the same. So, if we call the new height
, the preservation of the width/height ratio is written as

Solving the proportion for
yields

Answer:
Justin is correct
Step-by-step explanation:
2x^5 - 4x^3 + 6x^8.
We need to rewrite the polynomial in decreasing order
6x^8 +2x^5 -4x^3
The leading coefficient is 6
