Answer:
s = 1,811 square foot
Step-by-step explanation:
Here, we want to calculate the area of the roof.
The best way to proceed here is by substitution.
We simply substitute the length and the price into the bid price equation to get the area of the roof.
From the original equation, the formula to use is ;
P = 1.85s + 4.2f
now from what we are given; s = ?
f = 190 feet and P = $4148
substituting these values, we have;
4148 = 1.85s + 4.2(190)
4148 = 1.85s + 798
1.85s = 4148 -798
1.85s = 3350
s = 3350/1.85
s = 1,810.810810810811
To the nearest square foot, s = 1,811
Answer:
2/7(x-2)=4x
(2×x-2×2)/7 = 4x
(2x-4)/7 = 4x
2x-4×(1) = 4x × 7 ( Cross multiply)
2x-4 = 28
2x = 32
2x÷2 = 32÷2
x=16
Answer:
B: The elevation of the chameleon
Step-by-step explanation:
The Fly is <em><u>above</u></em> the chameleon, so its elevation should be represented by a "positive number"(Example of positive number: 16)
Also,
The Grasshopper is <em><u>below </u></em>the chameleon, so its elevation should be represented by a "negative number"(Example of negative number: -23)
ඞHope this helps u because i got dis question from Khan Academyඞ
Answer:
there's nothing there
Step-by-step explanation:
i don't know what the question is here
<span>Think about this ... x can be any value and y will always equal 3.5.
If x is 0, then y = 3.5
If x is 1, then y = 3.5
If x is 5, then y = 3.5
</span><span>
If x is -4, then y = 3.5
If x is -10, then y = 3.5
If you plot all these points on a graph you should begin to see that the graph is a horizontal line that intercepts the y-axis at +3.5 and continues on forever in both plus and minus directions.
Any time that there is no x term in the equation, the graph is a horizontal line that crosses the y-axis at the given value of y. For example, the graph of y= -4 would be a horizontal line that crosses the y-axis at the point -4 and continues on forever in both directions (to the left and to the right). </span>
