Answer:
Martina has 18,000
Step-by-step explanation:
- Set up the 4/5 the amount Tamara has as a proportion. 4/5 = x/20000
- Then cross multiply
- 4 * 20,000 = 80,000
- 80,000 = 5x
- Divide and get 16,000 (This is 4/5 of what Tamara has)
- Set up what Martina has as a proportion. 8/9 = 16,000/x
- Cross multiply 8x = 16,000 * 9
- 8x = 144,000
- Divide by 8
- 18,000 :)
Slope is rise over run, or the change in y over the change in x. So, you go up vertically then directly horizontal and whatever the change is is the slope.
For example, the first one is -1/3. It's slope is going down to the right, so it's negative . It goes down 1 (y value) and over to the right 3 (x value). Since it goes down and to the right it is a slope of -1/3.
Answer:
396.5
Step-by-step explanation:
(-4) + 8 = 4

You follow bedmas (brackets, exponents,division,multiplication,addition,subtraction). First comes the brackets so you do (60 divided by 10) which is 6. You still have (6) which means you have to multiply it by 2. So you get 12. Now you got rid of the brackets so you can solve the rest. 90-12-4= 74.
