B: x = 5.5 or -5.5
(square root) -> 2x = 11
(divide by 2) -> x = 5.5 or -5.5
Answer:
Omar had the bigger transaction
Step-by-step explanation:
The absolute value of a number is basically the distance between that digit and zero (0) therefore making the absolute value always a positive number. In this instance, the absolute values would be the following
Omar |-15| = 15
Jake |10| = 10
Now that we have both absolute values we can see that Omar had the transaction that involves more money. Exactly $5 more than Jake's transaction.
Not sure what algebra tiles are
not sure how to absolutely prove
I can prove it works at least most of the time by subsitute ing number for x
remember that 0,1,2 have special properties and are not very good for subsituting so
try 4
4+8(4)=4(2(4)+1)
true or false?
4+8(4)=4(2(4)+1)
multipily
4+32=4(8+1)
36=4(9)
36=36
this is treu at least for the number 4
another way is to believe in the distributive property where
a(b+c)=ab+ac so then
4(2x+1)=4(2x)+4(1)=8x+4=4+8x
Answer:
Triangle 2
Step-by-step explanation:
That is Pythagorean Theorem, which is only for right triangles. The second triangle has the little square, so you know it is 90 degrees.
Answer:
3 rows/hour
Step-by-step explanation:
It is given that, Jose takes 120 minutes to weed 6 equal rows of vegetable plants in his garden.
120 minutes = 2 hours
We need to find the unit rate per hour for weeding these rows of his garden. It can be calculated as follows :
So, the rate for weeding these rows of his garden is 3 rows per hour.
