Step-by-step explanation:
-3/2 = -1.5.
3 x -2 = -6
Nope
3 x -1 = -3
Nope
3 x 1 = 3 Yes!!
Answer: 3
Step-by-step explanation:
the statement given us:
7a-5b+4
a= 2
b= 3
so we have:
7*(2)-5*(3)+4
14-15+4 = 3
the answer is 3
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
