Answer:
5m+50
Step-by-step explanation:
since it's regular all sides are equal
it's have 5 sides of m+10
1.5 !!!
Multiply 2/3 by 9/4
Well, the absolute value of a number would always be positive, which means the dots on the line is going to be on the right side of 0. In the choices, the only number line that qualifies is C.
Answer: the first one would be 31.65
Step-by-step explanation:
First you have to do the a2+b2 thing to get the adjacent number then you do cos^-1(6.98/8.2) and you’ll get 31.655
For the third one x will equal 44.41
Answer:
A=25
B=98
Step-by-step explanation:
You can see it as a 2-eq system.
Call A Joao's money and B Luiz's money. The sum is $123:
A + B = 123
As the half of Luiz's money + 1 is the double of Joao's money, we could represent this as:
(B/2) + 1 = 2A [this is what the last sentence says]
We can get the A value by dividing both sides by 2:
[(B/2) + 1]/2 = 2A / 2
B/4 + 1/2 = A
Then, replacing this A value on our first equation:
B/4 + 1/2 + B = 123
B/4 + 4B/4 = 123 - 1/2
(5/4)B = 122.5
Multiplying by (4/5) [or dividing by 5/4] to eliminate this 5/4:
(5/4) B * (4/5) = 122.5(4/5)
B = 98
Then we find A:
A = B/4 + 1/2 = 24.5 + 0.5 = 25
A=25
