Answer:
23
Step-by-step explanation:
Maybe you want to evaluate ...
f(x) = 3x^2 -2x +7
for x = -2.
Put the value of x where x is, then do the arithmetic.
f(-2) = 3(-2)^2 -2(-2) +7 = 3(4) +4 +7
f(-2) = 23
Answer:
(12 2/3)/( 2 1/3)= 38/7 or 5 3/7 or 5.43 decimal
Step-by-step explanation:
Simplify the following:
(12 + 2/3)/(2 + 1/3)
Put 2 + 1/3 over the common denominator 3. 2 + 1/3 = (3×2)/3 + 1/3:
(12 + 2/3)/((3×2)/3 + 1/3)
3×2 = 6:
(12 + 2/3)/(6/3 + 1/3)
6/3 + 1/3 = (6 + 1)/3:
(12 + 2/3)/((6 + 1)/3)
6 + 1 = 7:
(12 + 2/3)/(7/3)
Put 12 + 2/3 over the common denominator 3. 12 + 2/3 = (3×12)/3 + 2/3:
((3×12)/3 + 2/3)/(7/3)
3×12 = 36:
(36/3 + 2/3)/(7/3)
36/3 + 2/3 = (36 + 2)/3:
((36 + 2)/3)/(7/3)
36 + 2 = 38:
(38/3)/(7/3)
Multiply the numerator by the reciprocal of the denominator, (38/3)/(7/3) = 38/3×3/7:
(38×3)/(3×7)
(38×3)/(3×7) = 3/3×38/7 = 38/7:
Answer: 38/7
Answer:
your answer is 70 min to mow 5 lawns
Step-by-step explanation:
Step 1
if it takes him 28 min to mow 2 lawns.
to mow 4 lawns, it would be 28+28 or 28x2=56
step 2
to figure out how long t would take to mow 5 lawns, you first have to figure out how much time was spent on 1 lawn.
which is: 28/2= 14
Step 3
now all you have to do it add
56+14
which gives you the answer
<u><em>70</em></u>
