Answer:
x+4≤13
just analyze the words carefully and their meanings, ex.: no more than = ≤
if you wish for the answer to this inequality:
x ≤ 9
just subtract 4 from both sides to leave x alone
Answer:
Hulian's age is 7.
Thomas's age is 22.
Step-by-step explanation:
Let Hulian = h
Let Thomas = t
Set the system of equation:
h = t - 15
h + t = 29
Plug in t - 15 for h in the second equation:
(t - 15) + t = 29
Simplify. Combine like terms:
2t - 15 = 29
Isolate the variable, t. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. First, add 15 to both sides:
2t - 15 (+15) = 29 (+15)
2t = 44
Divide 2 from both sides:
(2t)/2 = (44)2
t = 44/2
t = 22
Plug in 22 for t in one of the equations:
h = t - 15
h = 22 - 15
h = 7
Hulian's age is 7.
Thomas's age is 22.

32 = 3x + 14
x = 6 hours.
Subtract 14 from 32: You get 18
Divide 18 and 3: You get 6 which is the hours.
hello :<span>
<span>an equation of the circle Center at the
A(a,b) and ridus : r is :
(x-a)² +(y-b)² = r²
in this exercice : a = - 3 and b = 2 (Center at </span></span> A(-3,2))
<span>
r = AP....P(2,-5)
r² = (AP)²
r² = (2+3)² +(-5-2)² = 25+49=74
an equation of the circle that satisfies the stated conditions.
Center at </span> A(-3,2), passing through P(2, −5) is : (x+3)² +(y-2)² = 74
Answer:
d = -2
Step-by-step explanation:
2d - 5d = -3d
10 - 4 = 6
-3d = 6
d = -2
