Answer:
9
Step-by-step explanation:
find absolute value
I would say like 16 for the sides or for degrees I wold say 90 for the right angle or 30 for the acute angle
1. 35x + 0.15y
=3500x + 15y [multiplying the equation by 100]
= 700x + 3y [dividing the equation by 5]
2. Let x be an even integer
x + (x+2) + (x+2+2)
x+x+2+x+4
3x+6
3. 1/5*(r+7) - 9s
(r+7)/5 - 9s
4. x=cows
y= goats + sheep
x= (y+140)/2
Answer:
Step-by-step explanation:
<u>Given system:</u>
- 2x + y = 7 ⇒ y = -2x + 7
- y + 5 = -2x ⇒ y = -2x - 5
<u>We observe that:</u>
- The slopes are same m = -2
- The y-intercepts are different, b = 7 and b = - 5
- The lines are parallel, so no solution
Correct choice is C
