Step-by-step explanation:
let the numbers x and y
so x + y =13
x - y = 5
add two equations together
2x = 18
divide both side by 2
x = 9
sub in any equation
9 + y =13
y = 4
the numbers are 9 and 4
Answer:
98
Step-by-step explanation:
Mathematically, when we add all the angles of a triangle, we get 180
Thus;
x + 1 + 2x-2+ 3x-5 = 180
6x-6 = 180
6x = 186
x = 186/6
x = 31
so the measure of the biggest angle is 3x -5
= 3(31) + 5 = 93 + 5 = 98
To get for the taxi accidents in 1998, we must note that x =
8. Therefore using the equation y=−143.3x2+1823.3x+6820 , we can
calculate for the number of taxi accidents.
y = -143.3 * (8)^2 + 1823.3 * 8 + 6820
y = 12,235.2
There were about 12,235 taxi accidents in 1998.
