Answer:
4-(-10)
Step-by-step explanation:
17 less than 6+1 is negative 10 so 4 minus negative 10
Answer:
m∠2=65
Step-by-step explanation:
They are corresponding angels which means they are congruent.
Answer:
x< -1/4
Step-by-step explanation:
- 3/5 x + 1/5 > 7/20
Subtract 1/5 from each side
- 3/5 x + 1/5-1/5 > 7/20-1/5
-3/5x > 7/20 -1/5
Get a common denominator
-3/5x > 7/20 -1/5*4/4
-3/5x > 7/20 -4/20
-3/5x> 3/20
Multiply by -5/3 to isolate x
Remember that flips the inequality
-5/3* -3/5 x < 3/20*-5/3
x < -1/4
Answer:
x = 2.5 or -0.8
Step-by-step explanation:
Here, we are to use completing the square method to solve for the values of x
Firstly, we divide through by 4
= x^2 -7/4x -2 = 0
Now, we move the two term to the right hand side
x^2 -7/4x = 2
Now, we divide the coefficient of x by 2 and square it;
That would be;
(-7/4 * 1/2)^2 = 49/64
we now add this value to both sides of the equation
x^2 -7/4x + 49/64 = 2 + 49/64
The right hand side can be rewritten as;
(x-7/8)^2 = 177/64
taking the square root of both sides
x-7/8 = √(177/64)
x = 7/8 ± √(177/64)
x = 7/8 + √(177/74) or 7/8 - √(177/64)
= x = 2.53802 or -0.788017
Which to the nearest tenth is
x = 2.5 or -0.8
Okay. To find the distance apart from each other, subtract 15.3 and 7.5. When you do that, you should get 7.8. -7.5 and -15.3 are 7.8 units away on a number line.
