Answer:
x = 11
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
sum the 3 angles and equate to 180
5x + 4 + 6x - 3 + 4x + 14 = 180 ← collect like terms on left side
15x + 15 = 180 ( subtract 15 from both sides )
15x = 165 ( divide both sides by 15 )
x = 11
5 pennies (5c)
9 nickels (45c)
21 dimes ($2.10)
15 quarters ($3.75)
We then all the totals together for how much money the bank has
$6.35
Answer:
The answer is B. 50
Step-by-step explanation:
180-105=75
75+55=130
180-130=50
The two points we are given will tell us the slope of the line, and the first point even tells us the y intercept.
slope = (y2 - y1) / (x2 - x1) = (1 - 4) / (1 - 0) = -3/1 = -3
Since the function goes through (0,4), our y intercept is 4.
Now we can fill in our function:
<span>y = _ x + _
</span><span>y = -3x + 4</span>
