Hello
This question requires us to change the subject of a formula. This can be achieved by following the order of operations in reverse. First, isolate the terms with our variable of interest, x:
ax - bx = z - y
Then, we take x out as it is being multiplied to both a and b:
x(a - b) = z - y
Dividing (a - b) on both sides, we get:
x = (z - y) / (a - b)
Thus, the answer is A
Answer:
22
Step-by-step explanation:
f(x)=(3x+4)-(2-x)
Let x =5
f(5)=(3*5+4)-(2-5)
Do the parentheses first
= (15+4) - (2-5)
= 19-(-3)
= 19+3
= 22
8*2*5= 80 because volume= length*width*height
ANSWER
169.1m
EXPLANATION
From the diagram, the horizontal distance traveled is x meters.
This is the side adjacent to the 6° angle.
Since we know the hypotenuse to be 170m, we use the cosine ratio to find the value of x.
![\cos(6 \degree) = \frac{opposite}{hypotenuse}](https://tex.z-dn.net/?f=%5Ccos%286%20%5Cdegree%29%20%20%3D%20%20%5Cfrac%7Bopposite%7D%7Bhypotenuse%7D%20)
![\cos(6 \degree) = \frac{x}{170}](https://tex.z-dn.net/?f=%20%5Ccos%286%20%5Cdegree%29%20%20%3D%20%20%5Cfrac%7Bx%7D%7B170%7D%20)
.
This implies that
x=170cos(6°)
x=169.0687222
To the nearest tenth, the horizontal disance travelled is 169.1m
7.309
The thousandth is third number to the right of the decimal. We round 5+ up and 4- we round down.
So we round the decimal into third place, the fourth place is the 7 so we round that up, and we get 7.309
