3 was not multiplied by -4
It should be :
3(p - 4) = 3p - 12
Answer:
B
Step-by-step explanation:
-5x = y - 5 (1)
-2y = -x - 21 (2)
Change x to the left hand side of equation (2)
x = 2y - 21 (3)
Multiply (1) by 2 times:
-10x = 2y - 10 (4)
Use (4) - (3)
-10x = 2y - 10
- x = 2y - 21
-11x = -10 + 21
-11 x = 11
x = -1
Apply x = -1 in (1)
-5*(-1) = y - 5
5 = y-5
y = 5+5
y = 10
So x = -1
y = 10
Hope this help you :3
<span>Use the graph of the function to find its average rate of change from
=x−3
to
=x3 </span>is x<2\3
First add 5 to right side

Next , to cancel the 7, you need to multiply by 7 on both sides
Hello! We can go ahead and eliminate C and D, because those answers don't make any sense. There are 2 cups in 1 pint and there are 4 pints. 2 * 4 is 8. There are 8 cups in 4 pints. The cost for that much ice cream is $16.39. To dins the cost per cup, let's divide that number by the number of cups, which is 8. 16.39/8 is 2.04875 or 2.05 when rounded to the nearest hundredth. The cost for a cup of ice cream is $2.05. The answer is A: $2.05.
