❖ 6 + 45 ÷ 3² = 11
Follow order of operations:
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction
(Note: Multiplication and division can be done in either order as well as addition and subtraction.)
There are no parenthesis in this problem so we skip to exponents. The exponent is 3² which is 3 x 3 = 9.
We then have division. 45 ÷ 9 = 5
Our last step is addition.
Add:
6 + 5 = 11

Answer: B) 10 three-point questions and 14 five-point questions
<u>Step-by-step explanation:</u>
x represents three-point questions
y represents five-point questions
3x + 5y = 100 → 1(3x + 5y = 100) = 3x + 5y = 100
x + y = 24 → -3(x + y = 24) = <u> -3x -3y = -72 </u>
2y = 28
y = 14 (five-point questions)
x + y = 24
x + 14 = 24
x = 10 (three-point questions)
Answer:
y=(2/3)x
using m=(Y2-Y1)/(X2 -X1)
where the coordinates used are ( -3,-2) and (3,2).
The equation of the line is give by the formula, Y - Y1=m(X -X1)
Hello,
y=8/6 x-40/6
