Cross multiply
3(2x + 1) = 5(2x - 5)
expand by using distributive property
6x + 3 = 10x - 25
-4x = - 28
x = 7
Answer:
x=21
Step-by-step explanation:
61+34 = 95
360( a circle) - 95 = 265
265 +7 +22 = 294
9x+5x=14x
294=14x (divide both by 14 to get x)
X=21
Part.1Given equation:
C(t) = -0.30 (t – 12)²<span> + 40
</span>For t = 0
C(t) = -0.30 (0 - 12)² + 40
C(t) = -0.30 (-12)² + 40
C(t) = -3.2<span>
</span><span>For t = 12 (noon)
C(t) = -0.30 (12 - 12)</span>² + 40
C(t) = -0.30 (0)² + 40
C(t) = 40
<span>For t = 24 (midnight)
</span>C(t) = -0.30 (24 - 12)² + 40
C(t) = -0.30 (12)² + 40
C(t) = -0.30 × 144 + 40
C(t) = - 43.2 + 40
C(t) = -3.2
Part.2
Graph of the equation is given in the attachment.
Part.3
C(t) = –0.30(t – 12)²<span> + 40
F(t)=9/5C(t)+32
Substituting the values:
</span>F(t)=9/5{–0.30 (t – 12)² + 40}+32
F(t) = -0.54 (t – 12)² + 72 + 32
F(t) = -0.54 (t – 12)² + 104
Answer:
15740000 million dollars in profit in year 4
Step-by-step explanation:
Now since you didn't provide the table, im going to have to assume the years are going to be the X while the Y is going to be profit.
Using the equation you provided y=-0.34x^2+4.43x +3.46, we can simply put 4 as our x value (since x represents years) and we would get 15.74. Now you have to remember to convert it into millions to show the profit so 15.74 times 1,000,000 would be 15740000 million dollars
Answer:
Shirt #1
x = 63.84 - y - z
Shirt # 2
y = 63.84 - x - z
Shirt # 3
z = 63.84 - x - y
Step-by-step explanation:
First calculate the value of the 3 shirts as follows:
$ 71.83 - $ 7.99 = $ 63.84.
$ 63.84.
The general equation would be, where x is the value of shirt # 1, and the value of shirt # 2 and z is the value of shirt # 3:
x + y + z = 63.84, then for each shirt would be the following equations:
Shirt #1
x = 63.84 - y - z
Shirt # 2
y = 63.84 - x - z
Shirt # 3
z = 63.84 - x - y
For example, if we give values (always the sum of both under 63.84) to two shirts, x = $ 20, y = $ 30 then the value of shirt # 3 would be:
<em>z = 63.84 - 20 - 30 = $ 13.84</em>
