Answer: ![x=-\frac{5}{3}](https://tex.z-dn.net/?f=x%3D-%5Cfrac%7B5%7D%7B3%7D)
Step-by-step explanation:
Given the equation
, you need find the value of the variable x.
Then, you have to solve for x:
Add
to both sides of the equation.
Divide by -8 to both sides of the equation.
Once you do this proccedure, you will get the value of the variable x.
Then:
![-8x-\frac{7}{3}+\frac{7}{3}=11+\frac{7}{3}](https://tex.z-dn.net/?f=-8x-%5Cfrac%7B7%7D%7B3%7D%2B%5Cfrac%7B7%7D%7B3%7D%3D11%2B%5Cfrac%7B7%7D%7B3%7D)
![-8x=\frac{40}{3}\\\\\frac{-8x}{-8}=\frac{\frac{40}{3}}{-8}\\\\x=-\frac{5}{3}](https://tex.z-dn.net/?f=-8x%3D%5Cfrac%7B40%7D%7B3%7D%5C%5C%5C%5C%5Cfrac%7B-8x%7D%7B-8%7D%3D%5Cfrac%7B%5Cfrac%7B40%7D%7B3%7D%7D%7B-8%7D%5C%5C%5C%5Cx%3D-%5Cfrac%7B5%7D%7B3%7D)
If you are moving the decimal point to the left, the exponent is negative. If you move it to the right, the exponent is positive.
There is only one negative exponent here, and it is the first option.
So:
A number is being written in scientific notation. The student moves the decimal point to the left 3 places and A<span>. multiplies by 10^-3.</span>
Slope m= 7
From general equation of a line;
y=mx+c
y=7x+c
Finding value of c by replacing for;
y=-3
x=-4
-3=7*(-4)+c
-3=-28+c
c=25
y=7x+25
The length of the toy tractor is 3.125ft
Data Given;
To solve this question, we need to find the length of the tractor using ratios.
<h3>What is Ratio</h3>
This is the proportion of a substance to the entire value of that substance.
If the length of the tractor is 25 ft, then the length of the toy tractor can be found when we divide 25 by 8.
![l = 25/8 = 3.125ft](https://tex.z-dn.net/?f=l%20%3D%2025%2F8%20%3D%203.125ft)
The length of the toy tractor is 3.125ft.
