Apples are $0.68 and peaches are $0.42.
To find these values, we need to write and solve the following system of equations.
6x + 9y = 7.86
4x + 5y = 4.82
Multiply the first equation by 2 and the second by -3.
12x + 18y = 15.72
-12x - 15y = 14.46
Add the equations together.
3y = 1.26
y = 0.42
Sub in 0.72 and solve for x in either equation and you will get x = 0.68.
Answer:
8.69 × 10^4
For a clearer answer look at the image.
Step-by-step explanation:
10² + 10² = 10^4
5.84 + 2.85 = 8.69
8.69 × 10^4
I have been trying but i am pretty sure it is 36 i think
Answer:
No solution
Step-by-step explanation:
4x + y = -2
-20x - 5y = -3
<u><em>Using the Elimination method </em></u>
(4x + y = -2 ) 5
20x + 5y = -10
-20x - 5y = -10
0 = -10
No Solution
Answer:
percentages are used like fractions and decimals, as ways to describe parts of a whole. For example, discounts in shops, bank interest rates, rates of inflation and many statistics in the media are expressed as percentages. Percentages are important for understanding the financial aspects of everyday life. When you are using percentages, the whole is considered to be made up of a hundred equal parts. The symbol % is used to show that a number is a percentage, and less commonly the abbreviation 'pct' may be used.
