<span>Subtract 51 from both sides
</span><span>y−51=−3z</span><span>
Multiply both sides by <span>−1</span>
</span><span>−y+51=3z</span>
<span>
Divide both sides by 3
</span><span><span><span>51−y</span>3</span>=z</span>
<span>
Switch sides
</span><span>z=<span><span>51−y</span><span>3</span></span></span> is the answer
I may not be right.
Answer:
X=22.5
Step-by-step explanation:
The tiny square at the bottom means 90⁰ angle, so all together that's what the X's together means.
So 90÷4x =22.5
I think it is C because it’s taking it
Answer:
- y = 1.8x +53.7
- 73.5 in 2005
Step-by-step explanation:
The 2-point form of the equation of a line is useful here. It tells you that for the points (x1, y1) and (x2, y2) the line can be written as ...
y = (y2 -y1)/(x2 -x1)(x -x1) + y1
For your given points, this is ...
y = (60.9 -57.3)/(4 -2)(x -2) +57.3
y = 1.8(x -2) +57.3
y = 1.8x +53.7 . . . . . simplify
__
For x = 11 (in 2005), the predicted value is ...
y = 1.8·11 +53.7
y = 73.5
The first step is to find the volume of the truck bed in feet.
Volume = length times width times height
V = 10 • 8 • 3.5
The last measure is 3.5 since 6 inches is half of 1 foot.
10 • 8 = 80
80 • 3.5 = 280
So the truck can carry 280 cubic feet of sand.
Since the question is asking for cubic yards, though.
1 cubic foot = 0.037037 cubic yard
We have to multiply 0.037037 by 280 to find the answer.
280 • 0.037037 = 10.37036
So the truck can carry about 10.37 cubic yards of sand.
Answer:
10.37 cubic yards
