Systems of Linear Equations with Infinitely Many Solutions
Answer:
i believe it is -4 1/3 i may be wrong
Step-by-step explanation:
difficult, let me see....
1st slope:-4
2nd slope:4/6
3rd slope:-3
-2+4/7-3=-5+4/6=-4 2/6=
-4 1/3
Answer:
Hair Length – 14 = 1/2 (Months – 3)
Step-by-step explanation:
Answer:
apple = 4
blackberry =5
Step-by-step explanation:
Let a = apple pie cost
b =blackberry pie cost
4a +9b = 61
7a +6b = 58
Multiply the first equation by 7
7(4a +9b) = 61*7
28a +63b = 427
Multiply the second equation by -4
-4(7a +6b) = 58*-4
-28a -24b = -232
Add these two new equations together to eliminate a
28a +63b = 427
-28a -24b = -232
-----------------------------
0a +39b =195
Divide each side by 39
39b/39 = 195/39
b= 5
Now we need to find a
4a +9b = 61
4a +9(5) = 61
4a +45 = 61
4a+45-45 =61-45
4a = 26
Divide by 4
4a/4 =16/4
a = 4
Answer:
its 5%
