Where? I’m sorry but I can’t help if there isn’t any photo or equation/word-problem.
Answer:
Amount invested at 7% = 16000
Amount invested at 9% = 12000
Step-by-step explanation:
Let x be the amount invested at 7% and y be the amount invested at 9%.
Since the total amount invested is $28000, therefore, we can set up the first equation as:
Secondly, we are give that sum of two investments is $2200. Therefore, we can write the second equation as:
Now we need to solve these two equations to get the values of x and y.
First of all, we multiply the second equation with 100 in order to get rid of decimal values.
Let us use substitution method here. First of all we will solve for y from first equation and plug that into second equation.
Therefore, amount invested at 7% is $16000 and amount invested at 9% is 28000-16000=$12000.
Answer:
0 Siblings: 4 Students
3 or more siblings: 5 students
Step-by-step explanation:
The numbers at the bottom represents how many siblings they have and the dots represent the number of studens so using this we know:
0 Siblings: 4 Students
1 Sibling: 3 Students
2 Siblings: 3 Students
3 Siblings: 1 Student
4 Siblings: 0 Students
5 Siblings: 2 Students
6 Siblings: 1 Student
7 Siblings: 1 Student
3 or more: 1 + 0 + 2 + 1 + 1 = 5
3 or more siblings: 5 students
The answer is 7/5 th. You can add fractions without first having a common denominator so you would change the 8's by multiplying it by 5 to get 40 and you would multiply the 5 by 8 to get 40 as well. And the rule whatever you do to the bottom you have to do to the top so whatever you multiplied 8 by do the same for the numerator and whatever you multiplied 5 by you do the same for the numerator. So your new equation would be (75/40+16/40)+(-35/40). you would then add the numerator's across to get 56 and the denominator would stay the same so the answer is 56/40. But you have to now simplify 56/40 down to 14/10 and then once more to 7/5 which is the final answer.
