I believe this is J with a radius of 6
the formula for circumference is 2(pi)r so i just took the 12(pi) and divided it by 2, which left me with 6(pi), meaning that 6 would be the "r" in the situation
7.75 and 45 are the variables in this equation
2 wks = 38 cm SO
1 wk= 19 cm
19 cm a week
19 x 3 = 57
1/2 wk = 8 cm
57 + 8 = 65 cm in 3 1/2 weeks
Answer:
15 ft
Step-by-step explanation:
cause
24/8=3
5×3=15
The first step of solving this is to isolate the variable y in the first equation.
3x - y = -2 Subtract -3x from both sides
- y = - 3x - 2 Divide both sides by -1
y = 3x + 2
Now, substitute that y value into the second equation.
2x^{2} - y = 10 Substitute
<span>2x^{2} - (3x + 2) = 10 Multiply all of the numbers in the parentheses by -1
2x^{2} - 3x - 2 = 10
</span>
<span>So the correct answer choice is D) 2x^{2} -3x - 2 = 10.</span>
