Answer:
a = 18.15
Step-by-step explanation:
Combine like terms on the left side of the equation first. Add 7 and 42, then subtract 32 from the answer you get, then subtract 32 from that answer. This is going by order of PEMDAS.
Remember PEMDAS: (numbers 3 & 4 and numbers 5 & 6 are solved from left to right)
- Parentheses
- Exponents
- Multiplication
- Division
- Addition
- Subtraction
After combining like terms on the left side, you get -15. Now combine like terms on the right side of the equation by adding 14.3 and 7.
Get -2a alone by subtracting 21.3 from both sides.
Divide both sides by -2.
In this equation, a should equal 
.
Answer: 55
Step-by-step explanation: There is one simple theorem we need to know in order to solve for this.
Triangle Angle-Sum Property: All three angles interior angles of a triangle add up to 180°.
Thus, we could label the points A, B, and C, and set up an algebraic expression.
Let A = 27, B = 98, and C = x.
A + B + C = 180°.
Substituting A, B, and C we get:
27 + 98 + x = 180°.
Adding, we get:
125 + x = 180°
Subtracting 125 by 180, we get:
x = 55°
Thus, the angle X is 55°.
We could have simply solved this by just doing 180 - 98 - 27 = 55 in the first place, but I wanted to show you how I got such results.
Answer: 9.8 ft
Step-by-step explanation: did on delta math:)
The independent variable is the factor that you purposely change or control in order to see what effect it has. The variable that responds to the change in the independent variable is called the dependent variable. It depends on the independent variable. The independent variable is graphed on the x-axis.
To identify dependent studies variables, search for objects in your studies query or speculation that sees the result, effect, or outcome of changing the independent variable. The basic rule is to search for what reasons for reactions and what receives the results.
The statistical courting between variables is referred to as their correlation. A correlation might be high-quality, which means each variable circulates in the same direction, or bad, meaning that once one variable's price will increase, the opposite variables' values decrease.
Making sure that certain research variables are managed will increase the reliability and validity of the test, by ensuring that other causal consequences are removed. This safeguard makes it simpler for other researchers to repeat the experiment and comprehensively test the results.
