Okay. First things first, we can find the unit rate of chocolate cakes that the bakery sells. 44 chocolate cakes are sold in 4 days. 44/4 is 11. 11 chocolate cakes are sold per day. Now, we can multiply that total by 8 to get the total for 8 days. If you know basic multiplication, this one's simple. 11 * 8 is 88. There. The bakery can sell 88 chocolate cakes in 8 days.
The given proportional relationship is y = -5x.
Therefore the ratio
y/x = -5 = -5/1
If x changes by 1, then y/x = y/1 = -5.
This means that y changes by -5 when x changes by 1.
The ratio of vertical change is -5:1
The standard equation for a straight line is
y = m*x + c
where
m = the slope,
c = the y-intercept.
Therefore the given relationship is a straight line with a negative slope of -5. This means that y decreases as x increases.
Answer: C
-5:1
The graph decreases from left to right.
Answer:
31 inches. Add all the sides together. The height is not needed. 6.5+13.5+4+7=31 inches.
Step-by-step explanation:
Answer:
a. The student's conclusion is incorrect because the solution to the system of equations 3x + 4y = 32 and 5x + 5y = 50 is (8, 2).
Step-by-step explanation:
The second equation needs to be ...
5x +5y = 50
because the wording "short of $18" means that the actual cost of that purchase would be $18 more than the $32 that Harry had. 18+32 = 50.
The only answer choice that shows this as the second equation is choice A.

In fact, the solution to the system of equations is (8, 2), as can be seen in the graph below.
