Answer:
D. <em>Marie can make 60 pies</em>.
Step-by-step explanation:
In this problem, we know that amount of small mango pies is directly proportional to the amount of mangoes. The amount needed for preparing an amount of pies is calculated by simple rule of three:
A. <em>Marie can make 30 pies</em>.
25 mangoes are required for producing 30 pies.
B. <em>Marie can make 40 pies</em>.
34 mangoes are required for producing 40 pies.
C. <em>Marie can make 50 pies</em>.
42 mangoes are required for producing 50 pies.
D. <em>Marie can make 60 pies</em>.
50 mangoes are required for producing 60 pies.
The complete statement is: <em>Marie can make 12 small mango pies for every 10 mangoes.How many pies can she make with 50 mangoes. </em>
Hence, correct answer is D.
129 divided by 5 is equal to 25 with a remainder of 4.
This means that she will need a total of 26 boxes, but only 25 of them will have 5 cupcakes in them. The last one will have 4 cupcakes.
Answer:
Step-by-step explanation: We know that:
and we want:
.
We can form the numerator using just the first fact (since 5^2 is 25) and the denominator using the latter two (since 3*7 = 21).
The logarithm of a division can be expanded by subtracting the numerator and denominator (while still keeping the log). The logarithm of a product can be expanded by adding the terms while keeping the log. If the logarithm is raised to a power, we can bring it down as a factor:
.
Substituting the variables:
Answer:
x = -1
Step-by-step explanation:
The first step is get rid of the numbers outside this (). So we will get
20+8x=9x+21 (multiplication) And we can get rid of one side of x by subtract 8x on both sides, an then we will get 20= x+21
And we can move the numbers to one side by subtract 21 on each side, and we will get -1=x
And rewrite it:
x = -1
That's the answer.
