Answer: Choice B</h3>
Doug borrowed $2 from his friend every day from Monday through Friday. How much money does Doug owe in all?
==============================================================
Explanation:
The notation 5(-2) is the same as saying "5 times negative 2"
The negative represents the amount of debt that Doug goes into when borrowing that $2. When borrowing the same amount over the course of 5 days, he'll be in debt a total of 10 dollars. So we'd write -10 to represent this.
You could also write it out the longer way
-2 + (-2) + (-2) + (-2) + (-2) = -10
There are five copies of "-2" being added up to arrive at -10
Though it's much simpler to say
5(-2) = -10
The equation of a circle with centre (a,b) and radius r is:
(x - a)^2 + (y - b)^2 = r^2
thus,
here centre (a,b) = (-3,6), a = -3, b = 6
and radius = diameter/2 = 20/2 =10 units
therefore, the equation is
(x + 3)^2 + (y - 6)^2 = 100
which is c.
Because its only divisors are 1 and itself.
51 is the highest multiple you can take from 53
One way to find this out is take 53-30 and you get 23 from this you know 21 is the highest multiple you can get so 30+21 = 51
51/3 is 17 so each student gets 17 blocks and the thus remainder is 2
Another way is to divide 30 and 21 by 3 and add them both together and you will get the same answer
Do always make the numbers easier to solve and save time scrambling..
Someone already answered but i’ll explain it.
For #1: The sum of all 3 angles in a triangle will be 180. So since one corner is a right angle, that’s 90. The other angle is 17. So 90 + 17 = 107. Then do 180 -107 to find the last number. Which is 73!
