36 apples, you need to multiply 9 and 4 since there are 9 pies and 4 apples in each pie
7x+5y=-24 (1)
4x+y=42 (2)
multiply equation (2) by 5 to get
20x+5y=210 (3)
then calculate (3)-(2) which gives you
13x=234 hence x=18
then substitute for x in either equation to get y=-30
Add the two monthly incomes together:
1400 + 1100 = 2500 a month.
There are 12 months in a year, multiply the monthly income by 12:
2500 * 12 = $30,000 per year.
Answer:
70
Step-by-step explanation:
complementary angles are 2 angles that add up to 90, the first angle is already 20 so just subtract 90-20 to find other angle
First you need your y values. Than you will graph the x values on the horizontal axis, and the y values on the vertical axis.
