Answer:
y = 38
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Consider the angles in the large outer triangle, then
x + 46 + 78 = 180
x + 124 = 180 ( subtract 124 from both sides )
x = 56
Consider the 3 angles in the smaller inner triangle, then
y + x + 86 = 180 , that is
y + 56 + 86 = 180
y + 142 = 180 ( subtract 142 from both sides )
y = 38
I assume you mean -x^3 + 4x + 3
so what you need is 4x + 3 > x^3
the only whole number it could be is 2 because 2x2x2 +3 > 2x2x2
Step-by-step explanation: Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
Step-by-step explanation:
298-58=248
248/2=124
small one=124
big one=(124+58)=182
Basically what your gonna do is do 199 divided by 8 so you would need 25 boats, because it would be 24.875 rounded its 25
