Answer:
Fast car = 45.6
Slower car = 30.4
Step-by-step explanation:
Let the speed of the first car = x
Let the speed of the second car = y
Travelling towards each other.
x *1 + y*1 = 76 miles
x*5 - y*5 = 76 miles. This is kind of tricky. You have to understand that the first car that is 76 miles from the second car and makes up that 76 in 5 hours. The distance they both travel is subtracted out.
Divide by 5
x - y = 76/5
x - y = 15.2 The speeds differ by 15.2
x + y = 76
x - y = 15.2
2x = 91.2
x = 45.6
y = 76 - 45.6 = 30.4
When the two vehicles speeds are multiplied by 5, the difference is 76 km
Answer:
-8y=6
Step-by-step explanation:
-6x+6x =0
4+(-12)=-8
-8+14= 6
Answer:
D
12²
Step-by-step explanation:
Given in the question, an integer = 144
To find the exponential form 144 we will do factorisation
The prime factorisation of 144 is
2 × 2 × 2 × 2 × 3 × 3
So the exponential form is 2
× 3²
The other way is
√144 = 12
which means
12² = 144
The order from the least to the greatest is 
, 
, 
, and 
.
Step-by-step explanation:
Step 1:
We must determine each of the individual values to be able to arrange the given numbers.
means that so 1 and 7 in the decimal keep repeating so,
and
Now that we have all the four values, we can arrange them in ascending order.
Step 2:
There are two negative numbers, the greater a negative number the lesser it is i.e. 
So the least value is which is followed by .
The other two are positive numbers. As 
so the highest number is .
So the order from the least to the greatest is , , , and .
Answer:
.73(.004) or .00292
Step-by-step explanation:
First, you should look at the equation: (7.3x10^-1). This means you would have to move the decimal to the left one time. So, the equation would be .73(.004).
If you wanted to find the answer to this equation, you would get .00292.
Standard notation: (.73)(.004).
