Answer:
x = 14/3
y = 16.3333333333
Step-by-step explanation:
Step 1. equal them to each other and solve for x
2x + 7 = 5x - 7
5x - 2x = -14
3x = 14
x = 14/3
Step 2. Plug in the value of x and solve for y
y = 5x - 7
y = 16.3333333333
tadah!
Answer:
Dannielle's mistake was that she added the exponents,
x^3 + 5x^3, doesn't equal 6x^6
Step-by-step explanation:
the correct work is below:
x^3 + 5x^3 + 5x^2 - 3x^2 + 2x - 7 - 1
6x^3 + 2x^2 + 2x -8

Answer:
139
Step-by-step explanation:
So we start with PEMDAS. (Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction.)
Since we don't have parenthesis or exponents, we can go straight to multiplication. 9 multiplied by 14 is 126.
Now we go to addition. 126+1=127
127+12=139
Hope I helped :)
