The coordinates of the point intersection of lines (-1, -1)
If you want solve:
y = -2x - 3, y = 3x + 2
-2x - 3 = 3x + 2 |+3
-2x = 3x + 5 |-3x
-5x = 5 |:(-5)
x = -1
Put the value of x to the first equation:
y = (-2)(-1) - 3 = 2 - 3 = -1
x = -1, y = -1
Answer:
option 2 is better( 3 pizza with 30 inches diameter)
Step-by-step explanation:
Area of the large pizza = A=πr^2=962.11 * 2( for two pizzas)=1924.22
Area for small pizza : A=πr^2=706.86*3 pizza=2120.58
your buying more pizza for less price
(there are more than one way to figure the answer)
Answer:
360
Step-by-step explanation:
24 divided by 6 = 4 which means each foot = 4 foot shadow
90 x 4 =360
try 80 its the only one that makes a fleas wing of sense
So first you would simplify 3/4(5x-3) to 3(5x-3)/4
So it would be 3(5x-3)/4+8=17
2. Subtract 8 from both sides
3(5x-3)/4=17-8
3. Then simplify 17-8 to 9
3(5x-3)/4=9
4. Multiply both sides by 4
3(5x-3)=9x4
5. Simplify 9x4 to 36
3(5x-3)=36
6. Divide both sides by 3
5x-3=36/3
Simplify 36/3 to 12
5x-3=12
8. Add 3 to both sides
5x=12+3
9. Simplify 12+3 to 15
5x=15
10. Divide both sides by 5
X=15/5
Simplify 15/5 to 3
X=3
So your answer is x=3
