C - is a hypotenuse,
so we can use Pythagorean theorem.
c² =a² +b²
c² = 8²+12²=64 + 144 = 16*4 +16*9=16(4+9) =16*13
c²=16*13
c=√(16*13)=√16*√13=4√13
c=4√13
Answer C. 4√13
Answer:
8w^-1
Step-by-step explanation:
-64w^2/-8w^3
The negatives cancel out and 64 is divided by 8 to get.
So 8w^2/w^3
You then subtract the exponent in the denominator from the exponent in the numerator since they divide. So
8w^2-3=8w^-1
Answer:
Step-by-step explanation:
Put in the form of y = Ax + B
x + 2y = 10
2y = -x + 10
y = -½x + 5
has a slope of -½ and a y intercept of 5
-x + 4y = 8
4y = x + 8
y = ¼x + 2
has a slope of ¼ and a y intercept of 2
Answer:
Step-by-step explanation:
Equation: (3x+7) + (10x+17) = 180
*These are consecutive interior angles and they add to 180 degrees
1.) Add like terms
13x + 24 = 180
2.) Subtract 24 from both sides
13x = 156
3.) Divide each side by 13
x = 12
*Substitute x in both expressions to get angle measures
Value of x: 12
3(12)+7 = 36+7 = 43
10(12)+17 = 120+17 = 137
*Check 43+137 = 180
Angle Measures: 1st angle: 43 degrees
2nd angle = 137 degrees
Step-by-step explanation:
1/5x + 5x = 7x-18
now that the equation is formed, just find x!
move the whole numbers to one side,
5x-7x+1/5x = -18-1/5x
-2x+1/5x = -18
-1.8x = -18
x = 10
and to find out if 10 is the right value of x, just subsitute 10 back into the very first equation and if it balances out to 0 it ia the right answer. hope i helped!
