Use properties to find the sum or product 93 + (68+7)
2 answers:
The sum :93 + (68+7) = <u><em>168</em></u>
<h3>Further explanation</h3>Calculation operations include multiply, divide, add, substract, etc.
In mathematical operations we can use the order of operation / calculation according to the principle of <em>PEMDAS</em>
- P: Parentheses ⇒ ( )
- E: Exponents (powers, square roots, etc.)⇒√,²
- MD: Multiplication and Division ⇒ x and :
- AS: Addition and Subtraction ⇒ + and -
Multiplication and division or addition and subtraction are interchangeable/rank equally so the calculations/equation operations should be done from left to right
The sum or product 93 + (68 + 7)
From this problem, we can know that the calculated operation used is only an addition, so that the form of parentheses has no effect, but we still adjust to the guidelines in <em>PEMDAS</em> that we count the calculation operations in parentheses first
then :
6 squared divided by 2 (3) +4
an algebraic expression
Keywords: PEMDAS, arithmetic operations, multiply, divide, add, substract

The graph that matches the following system of equation is; the picture of a coordinate plane with line y equals negative 4x minus 1 and line y equals minus 3 over 2 times x plus 4. They intersect at negative 2, 7.
<h3>What is the graph of a function?</h3>The graph of a function y = f(x) shows the position of the x-intercepts and y-intercepts from the graph from which the slope can be drawn.
The system of linear equations can be rewritten in slope-intercept form as follows:
y = -4x - 1
y = -3/2x + 4
From the graph, the two equations intercept at point (-2,7).
