Answer:
Infinite amount of solutions
Step-by-step explanation:
Parallel lines have no solution
Same lines have infinite solutions
Intersecting lines have 1 solution
Step 1: Write out equation
-14(x - 5) = -14x + 70
Step 2: Distribute -14
-14x + 70 = -14x + 70
Here we see that we have 2 exact same lines. Therefore, we have infinite amount of solutions.
Alternatively, we can plug in any number <em>x </em>and it would work. So then we would have infinite amount of solutions as well.
Answer:
B. 20
Step-by-step explanation:
Cos a = b/c
Cos 53° = b/25
b = 25 × 0,6 = 15
x = √(25² - 15²)
x = √(625 - 225)
x = √400
x = 20
21/35= 3/5 this is the lowest fraction
Assuming that you ment- (18*9)/3d where d=3 you would follow PEMDAS-
Parentheses
Exponents
Multiplication-Division (in order from right to left)
Addition-Subtraction (in order from right to left)
1. Parentheses- (18*9)=162
2. Solve your variables- 3d (3*3)=9
Giving you- 162/9
3. Solve-162/9=18
