I think its 72 cause 8x3 is 24. and then 24x3 is 72.. let me kniw if im right!
Answer:
x = 2, y =7
Step-by-step explanation:
4x - 2y = -6
-6x + 2y = 2
Add the equations together
4x - 2y = -6
-6x + 2y = 2
-----------------------
-2x = -4
Divide each side by -2
-2x/-2 = -4/-2
x = 2
now find y
-6x+2y =2
-6(2) +2y =2
-12+2y =2
Add 12 to each side
-12+12+2y = 2+12
2y =14
Divide by 2
2y/2 =14/2
y =7
Answer:
1) 80 people 2) 15 weeks
Step-by-step explanation:
(x = the number of people)
500 + 8x = 1140 ← ($500 initially plus $8 per person equals $1140)
8x = 640 ←(subtract the $500 from each side)
x = 80 ←(divide by the $8 per person to get the number of people)
------
(x = the number of weeks)
242 = 62 + 12x ←(The cost of the snake ($242) is equal to her $62 plus $12 she saves every week)
180 = 12x ←(subtract the $62 from both sides)
15 = x ←(divide by the $12 per week)
I'm pretty sure this is D, but I'm not completely positive.
Since this triangle is an isosceles triangle, two of its angles are going to be equal. We know that all the angles in a triangle are equal to 180o.
Step 1: 180 - 98 = 82
Step 2: divide the sum of the two angles (82) to give me the measurement of one of the angles
82/2 = 41
