Answer: You use the rules of PEMDAS Parenthesis, Exponents, Multiply, Divide, Add, Subtract
Step-by-step explanation: First solve all equations inside of the parenthesis, so the equation becomes 4(5)-7+2
Then you multiply and the 4 by 5 and the equation becomes 20-7+2
Then you do all the adding and it becomes 20-9
Then subtract and you get 11
<A +<B + < C =180° ==>(5x+6) + (2x+1) + (6x+4) = 180°
13x = 180°-11° ==> 13x 169° and x =169/13 =13°
This equation is also equal to 3/4x - 2/3 + 5/6 + 2x since subtracting a negative is the same as adding a positive in the long run. First, simplify the variables to get 2 3/4x - 2/3 + 5/6. -2/3 is also equal to -4/6, so -4/6 + 5/6 is 1/6. The simplified version of this expression is 2 3/4x + 1/6. Hope this helps!
Answer:
Step-by-step explanation:
For what mileages will company A (which has a flat rate of $111) be less than the cost for company B
Company A < Company B
111 < 75 + 0.80m
solving
111 - 75 < 75 - 75 + 0.80m
36 < 0.80m
36/0.80 < 0.80m/0.80
as we are dividing by a positive number, we don't have to change the direction of the < sign.
45 < m
or m > 45
so if Ali intends to drive more than 45 miles, Company A's vehicle will be less expensive to rent
The first answer is 2
The Second is 8
The third is, if the w changes then the p would change as well resulting to multiplication
Hope this helps!!!
