The answer is:
a = c ÷ 2
b = P - a - c
The perimeter is the sum of all sides of a polygon. The perimeter of the triangle is:
P = a + b + c
where
P - perimeter of the triangle,
a, b, c - sides of the triangle.
It is given:
P = 14.5 cm
c = 6.2 cm
If, t<span>he longest side (c) is twice that of the shortest side (a), then
c = 2a
</span><span>Therefore, the equation that can be used to find the length of the shortest side is <u>a = c ÷ 2</u>.</span><span>
</span>⇒ a = c ÷ 2 = 6.2 cm ÷ 2
⇒ a = 3.1 cm
By knowing two sides (c and a) and perimeter (P), we can calculate the length of the third side (b).
If P = a + b + c, then <span>the equation that can be used to find the length of the side b is <u>b = P - a - c</u>.
</span>⇒ b = P - a - c = 14.5 cm - 6.2 cm - 3.1 cm
⇒ b = 5.2 cm<span>
</span>
One possible system of two equations is ...
x = -2
y = -3 .
Answer:
$48.60
Step-by-step explanation:
First multiply the amount due by the tax
45 x .08 = 3.6
Final step add the tax to the amount due
45 + 3.6 = 48.6

Answer:
45
Step-by-step explanation:
According to the Question,
- Given, Some boys and girls took part in a competition. 2/5 of the competitors were boys So 3/5 of the competitors were girls.
And there were Total 135 competitors.
So, the Number of Boys are 135 × (2/5) = 54 boys
Therefore, the Number of Girls in the competition is 135-54 = 81 Girls.
Now,
- 1/3 of the boys were disqualified from the competition. So, 54× (1/3) = 18 boys Disqualified . the Remaining boys are 54-18 = 36 boys left in Competition.
- Then, The number of girls more than that of boys left in competition were 81-36 = 45
