Lily saved 16 coins. She saved ten-can and one-dollar coins only. If she had $5.20, how many ten-cent coins did she have?

Firlakuza [10]

Answer:

Step-by-step explanation:

Let d represent the number of dimes Lily saved. Then the value of her coins in cents is ...

10d +100(16-d) = 520

-90d +1600 = 520 . . . . . eliminate parentheses, collect terms

-90d = -1080 . . . . . . . . . . subtract 1600

d = -1080/-90 = 12 . . . . . divide by the coefficient of d

Lily has 12 ten-cent coins.

In Bobby’s school, math grades for the year are calculated from assignments, tests and a final exam. Assignments count 30%, test

jarptica [38.1K]

Answer:

A) Bobby's overall grade is 70.4%

Step-by-step explanation:

To solve this problem we must calculate the percentages each grade represents from the overall grade. Therefore:

assignment = 85*30% = 85*30/100 = 25.5%

tests = 72*20% = 72*20/100 = 14.4%

exam = 61*50% = 61*50/100 = 30.5%

total = assignment + tests + exam

total = 25.5 + 14.4 + 30.5 = 70.4

Bobby's overall grade is 70.4%. Therefore the correct answer is A).

Bess [88]

Answer:

The equation to describe the situation is $p-3=17.$

And, the total weight of the basket of apples was 20 pounds.

Step-by-step explanation:

The question is incomplete so, the complete question is below:

Liang bought a basket of apples to make pies for her friends. The basket of apples weighed p pounds. Before she had time to make the pies, she ate 3 pounds of apples. There are 17 pounds of apples left to make pies. Write an equation to describe this situation. What was the total weight of the basket of apples?

Now, to write an equation to describe the situation. And to find the total weight of the basket of apples.

So, the basket of apples total weighed = $p\ pounds.$

Liang ate apples weighed = 3 pounds.

And the apples left for the pies weighed = 17 pounds.

Now, to write an equation describing the situation:

$p-3=17.$

Thus, the equation is $p-3=17.$

Now, to get the total weight of the basket of apples:

$p-3=17\\\\Adding\ both\ sides\ by\ 3\ we\ get:\\\\p=20$

Hence, the basket of apples total weighed = 20 pounds.

Therefore, the equation to describe the situation is $p-3=17.$

And, the total weight of the basket of apples was 20 pounds.
