Answer:
The answer is -33.
Step-by-step explanation:
To solve the given equation we will follow the PEDMAS rule.
PEDMAS stands for :
P = Parentheses
E = Exponents
M = Multiplication
D = Division
A = Addition
S = Subtraction
Solving the question by PEDMAS rule :








Hence, the answer is -33.

Answer:
The last one
Step-by-step explanation:
Because 0 < -2 -2, 0 <-4. It is not a true statement. It tell you that the middle one is wrong. The first one is wrong to because there are no equal sign.
Answer:
speed of motorcycle = 40 mph
speed of car = 50 mph
Step-by-step explanation:
Here is the complete question
A car and a motorcycle leave at noon from the same location, heading in the same direction. The average speed of the car is 30 mph slower than twice the speed of the motorcycle. In two hours, the car is 20 miles ahead of the motorcycle. Find the speed of both the car and the motorcycle, in miles per hour.
Speed = distance / time
This question would be solved using simultaneous equation
let m = average speed of the motorcycle
c = average speed of the car
c = 2m - 30 equation 1
20 =(c - m) x 2 equation 2
insert equation 1 into equation 2 and divide through by 2
10 = (2m - 30) - m
solve for m
m = 40 mph
substitute for m in equation 1
2(40) - 20 = 50 mph
Answer:
80
Step-by-step explanation:
because if you want to find a common denimeter we have mulitly the deometer to find the answer
sorry if it is wrong
