Answer:
18 and 52
Step-by-step explanation:
x + Y = 70
X - Y= 34 find the value of X interms of Y to find the answer:
X - Y= 34
X = 34 +Y
x + Y = 70
(34 + Y ) + Y = 70
34 + Y +Y = 70
2Y =70-34
2Y/2=36/2
Y = 18
x + 18 = 70
x=70 - 18
x= 52
check:
18 + 52= 70
52 - 18= 34
I'm going to go with 4 I hope I'm right if it's wrong I'm sorry
Answer is 150/x see photo for solution
Answer:
y = -x^2 − 2.5x + 350
Step-by-step explanation:
y = (10 + 0.5x)(35 − 2x)
y = 350 − 20x + 17.5x − x^2
y = 350 − 2.5x − x^2
Answer:
<h2><u>
104.9</u></h2>
Step-by-step explanation:
To find the circumference of a circle, we need to use the formula which is
C = 2*π*r
Rewrite with radius
C = 2*π*16.7
Solve
C = 2*π*16.7 = 104.876
Now we have to round. Remember, if it is 4 or below round down and if it is 5 or above, round up.
104.876 - 6 is more than 5
104.88 - 8 is more than 5
<u>104.9 is the final answer</u>
