$1820
Step-by-step explanation:
35 x 52 = $1820
Answer:
1. 10.5 liters
2. 1,500 cups of tea
3. 960 milliliters
4. 1/4 a liter
Step-by-step explanation:
1. If there are 7 days in a week, and she drinks 1.5 liters a day, we just multiply 1.5 (liters) x 7 (days) = 10.5 liters
2. There are 1000 milliliters in 1 liter. Multiply 1.5 liters by 1000 milliliters = 1,500 milliliters
3. If you multiply 800 by 0.2 (20%) you will get 160. Then add 160 + 800 = 960 milliliters
4. If you look at the fraction wall I included, you will see how there are 4/4 in 1 liter, and 2/2 in 1 liter. Half of a liter (1/2) is the same as 2/4. If you were to subtract 3/4 from 2/4, you'd get 1/4 left.
Hope that helps!
Answer:
Pete: 39, Linda: 42
Step-by-step explanation:
Suppose Pete has x dollars. If he has 3 dollars less than Linda, then Linda has 3+x dollars. Together, they have 81 dollars:
x+3+x=81
2x+3=81
2x=78
x=39
Since Pete has x dollars, and x=39, he has $39.
Linda has 3+x, which is 39+3 = $42

Answer:
see explanation
Step-by-step explanation:
Calculate the slopes between pairs of the 3 points using the slope formula
m =
with (x₁, y₁ ) = (- 9, 3) and (x₂, y₂ ) = (- 3, 9)
m = = = = 1
Repeat with (x₁, y₁ ) = (5, 1) and (x₂, y₂ ) = (- 3, 9)
m = = = - 1
If lines are perpendicular then the product of their slopes = - 1 , then
1 × - 1 = -1
Thus there is a right angle between the 2 lines
Then triangle is right- angled
When a number is next to a letter like so: 3m You would multiply, so
3 ~ 2 = 6 then solve the problem like this
11-3m= ?
3~2=6
6-11=5
so 11-3m=5
Hope this helps! :)
