Answer:
im sorry but what is the equation. It will have an equation listed below for you to plug in the numbers
Step-by-step explanation:
So the price is C
and 20 cakes is T
So 1 cake times 20=20 cakes
so 20C=T
Answer:
58°
Step-by-step explanation:
<h3>Angle sum property of triangle:</h3>
The sum of all angles of a triangle is 180°.
x + 69 + 55 + x + 78 = 180
x + x + 69 + 55 + 78 = 180
Combine like terms,
2x + 202 = 180
Subtract 202 from both sides,
2x = 180 - 202
2x = -22
Divide both sides by 2,
x = -22/2
x = -11
∠A = x + 69
= -11 + 69

I can't find that file. please give it again.
Answer:
Third option
Step-by-step explanation:
We can't factor this so we need to use the quadratic formula which states that when ax² + bx + c = 0, x = (-b ± √(b² - 4ac)) / 2a. However, we notice that b (which is 6) is even, so we can use the special quadratic formula which states that when ax² + bx + c = 0 and b is even, x = (-b' ± √(b'² - ac)) / a where b' = b / 2. In this case, a = 1, b' = 3 and c = 7 so:
x = (-3 ± √(3² - 1 * 7)) / 1 = -3 ± √2
