Answer:
C. C = 3P
Step-by-step explanation:
C = total costs
P = number of popsicles
Unit price of 1 popsicle = $3
To get the total cost of popsicles, we need to multiply the number of popsicles bought by the price of each popsicles
Total cost of popsicles = number of popsicles × unit price
Thus, the question would be written as:
C = 3P
Answer:
64 degree and 116 degree
Step-by-step explanation:
4y-44+3y+35=180(Linear pair)
7y=189
y=27
4(27)-44=64
3(27)+35=116
The answer is actually choice A
---------------------------------------------------------
---------------------------------------------------------
If we add up the equations straight down we will have 0a+2b = 6
Note how adding the 'a' terms gives us 3a + (-3a) = 3a-3a = 0a. The 0a term is really 0 since 0 times anything is 0. So the 'a' terms will go away
The equation 0a+2b = 6 turns into 0+2b = 6 and that simplifies to 2b = 6
To isolate b, we divide both sides by 2
2b = 6
2b/2 = 6/2
b = 3
We can stop here since only one answer choice has b = 3, which is choice A. However, let's keep going to find the value of 'a'
Plug b = 3 into any equation with 'a' and 'b', then solve for 'a'
3a+4b = 9
3a+4*3 = 9
3a+12 = 9
3a+12-12 = 9-12
3a = -3
3a/3 = -3/3
a = -1
So a = -1 and b = 3 pair up to form (a,b) = (-1,3)
--------------------------------------
To check, plug this ordered pair back into both equations
Equation 1:
3a+4b = 9
3*(-1)+4*3 = 9
-3+12 = 9
9 = 9
Equation 1 has been checked out
Equation 2:
-3a-2b = -3
-3(-1)-2(3) = -3
3 - 6 = -3
-3 = -3
this is true as well
So this confirms that the final answer is choice A
the answer is 11/4
The unit rate of change between variables is the quotient between the difference between y-values and the difference between x-values
