Answer:
q = -13.2
Step-by-step explanation:
9.7q = 9.1q - 7.92
Subtract 9.1q from both sides.
0.6q = -7.92
Divide both sides by 0.6
q = -13.2
Double check your work.
9.7(-13.2) = 9.1(-13.2) - 7.92
-128.04 = -120.12 - 7.92
-128.04 = -128.04
Distance = √(x₂-x₁)² + (y₂-y₁)²
d = √(-11-(-11)) + (5-(-20))²
d = √0² + 25²
d = √625
d = 25
In short, Your Answer would be 25 units
Hope this helps!
The usual!! Just add up 5.03+13.7 which is 18.73. Then add that up with 108 which is 126.73!
Answer:
18
Step-by-step explanation:
Let x represent smallest number and y represent second number.
We have been given that the biggest among three numbers is 2.4 larger than the smallest one. So biggest number would be 
.
We are also told that 15 times the smallest one is equal to 12 times the second and 10 times the third. We can represent this information in equations as:
Upon solving 2nd equation, we will get:
Therefore, the smallest number is 4.8.
The biggest number would be 
.
Upon substituting in equation (1), we will get:
Therefore, 2nd number would be 6.
Let us find sum of all numbers as:
Therefore, the sum of all 3 numbers would be 18.
<span>The goal in simplifying numbers
is to reduce it that can be best seen in the eye. In here, you are given 5a²x(-3b²)x2c. Note that 5, -3 and 2 are
coefficients and a², b² and c are variables. Multiply first the coefficients 5, -3
and 2 and you get -30. Always remember that in multiplying numbers, especially
variables, the base of the exponent must be equal. However, you have variables
of a²,
b²
and, c. You cannot multiply or add them because they are different. So the
answer is -30a² b²c.</span>
