what is -9/14+2/7 as a fraction in simplest form
_________
[tex] \: [/tex]
[tex] - \frac{9}{14} + \frac{2}{7} = ...[/tex]
[tex] = \frac{2}{7} - \frac{9}{14} [/tex]
[tex] = \frac{(28 - 63)}{98} [/tex]
[tex] = \frac{ -35 }{98} [/tex]
[tex] = \boxed{ \bold{ - \frac{35}{98}}} [/tex]
Answer:
5/14
Step-by-step explanation:
-9 is just 9 so that makes 9/14 - 2/7.
Multiply 7 by 2 and that makes 14, do the same with the numerator and that makes 4/14 and 9/14 - 4/14 = 5/14

The sum of three numbers is 88. The first number is 8 more than the second. The third number is 3 times the second. What are the numbers?
Answer:
The numbers are 24, 16 and 48
Step-by-step explanation:
For this equation you need to use all the information you have to add in 3 variables, use the information you have to connect them, so you only use one number. You’ll have the second number (x), the first number (x+8) and the third number (3x) now we use all of that to make an equation.
88=x+(x+8)+3x
Now you simplify the equation,
88=5x+8
Now get the x and it’s coefficient alone on one side
80=5x
Now divide both sides so the x is alone
x=16
Since the second number was x you know the second number
the first number is x+8 since x is 16 the first number is 24
The third number is 3 * x so the third number is 48.
So the numbers are 24, 16 and 48

Find: 11/3 divided by 2/3
The quotient is 5 and ______
Answer:
1/2
Step-by-step explanation:
11/3 divided by 2/3
=5.5
11/3 divided by 2/3 , the quotient is 5 and remainder is 1.
The divisor is the integer that divides a given number. The resultant number is sometimes referred to as the quotient. The residual is the number that the divisor leaves after partially dividing the original integer.
Let, first number is x and second number is y
On dividing given two number
Division=x/y
[tex]x/y=\frac{11/3}{2/3}[/tex]
[tex]x/y=11/2[/tex]
It is given that the quotient for dividing two numbers is 5.
Using,
Dividend = Divisor x Quotient + Remainder
Here,
Dividend =11
Divisor =2
Quotient =5
On, substituting these values to get Remainder
11=2 x 5+ Remainder
Remainder=1
Thus, remainder is 1.

1. Lucy monitors the position of a large fish in the ocean with a measuring tool. The tool records the depth (how deep the level) of the fish. Initially, the fish swims at a depth of 14 feet below sea level. Suddenly the fish rises 8 feet.
(a) What expression represents the position of the fish relative to sea level after it rises 8 feet?
(b) What is the position of the fish after it rises 8 feet relative to sea level? Show your work. Answer in a complete sentence.
Hint: Draw and label a picture to see and show what is happening.
Answer:
A) -14 + 8 = 6
B) The fish is at -6 feet below the sea level after it rises 8 feet because -14 (14 feet below 0) plus the 8 feet it rises is -6 feet or 6 feet below the sea level.

Use the point and the slope to graph cach line. Write the equation of the line.
The line passes through point (-1, 4) and has slope - 2.
Answer:
y=-2x+2
Step-by-step explanation:
We use the formula
y=mx+b, where m is the slope, b is the y intercept, and x&y are the coordinates.
We know that one point is (-1, 4)
and the slope is -2.
We are trying to find b.
In order to do that, we plug in what we know:
so,
4=-2(-1)+b
4=2+b
4-2=b
b=2
So now we go back to the original equation and use b as our value'
y=-2x+2

Find the magnitude of the vector (4, - 4).
Write your answer in simplified radical form.
Answer:
the magnitude of the vector is given by the √(px^2+py^2) so the value is 5.65
The magnitude of the given vector (4, -4) in the simplified form will be 5.65.
What is a Vector?A vector is a quantity with both magnitude and direction in physics. It is often depicted by an arrow with the same direction as the amount and a length proportionate to the size of the quantity.
A vector lacks position, but has magnitude and direction. A vector is therefore unaffected by displacement parallel to itself as far as its length is unaltered.
As per the given data in the question,
4² + (-4)² = 16 + 16
= 32
Magnitude = √32
Magnitude = 5.65
