Answer:
3x + 8y = 31
5x + 2y = 12
Let's solve your system by elimination.
Multiply the second equation by -4, then add the equations together.
(3x + 8y = 31)
−4 (5x + 2y = 12)
Becomes:
3x + 8y = 31
−20x − 8y = −48
Add these equations to eliminate y:
−17x = −17
Then solve −17x = −17 for x:
−17x = −17
−17x −17 = −17 − 17 (Divide both sides by -17)
x = 1
Now that we've found x let's plug it back in to solve for y.
Write down an original equation:
3x + 8y = 31
Substitute 1 for x in 3x + 8y = 31:
(3)(1) + 8y = 31
8y +3 = 31 (Simplify both sides of the equation)
8y + 3 − 3 = 31 − 3 (Add -3 to both sides)
8y = 28
8y8 = 288 (Divide both sides by 8)
y = 7/2

Write 34% as a fraction in simplest form
Answer:
The answer is that the simplest fraction form of 34% is 17/50
Step-by-step explanation:
Both the numerator and denominator of the fraction 34/100 can only be divided by 2, to satisfy creating its simplest form.
34% = 17/50
Have an awesome day! :D
Answer:
[tex]\frac{17}{50}[/tex]
Step-by-step explanation:
To write any fraction as a percent, remember perCENT means per 100. Think of 100 cents in a dollar. So 34 perCENT means 34 of 100, which you write as [tex]\frac{34}{100}[/tex].
Simplest form means to reduce, so you see if there is any number you can divide out of the top and the bottom.
[tex]\frac{34}{100}[/tex] = [tex]\frac{17*2}{50*2}[/tex]= [tex]\frac{17}{50}[/tex]

Estimate the total of 56.213, 7.983, and 0.344 by rounding each value to the nearest hundredth
Answer:
64.53
Step-by-step explanation:
56.213 rounds to 56.21
7.983 rounds to 7.98
0.344 rounds to 0.34
Next you do 56.21 + 7.98 + 0.34 = 64.53
All the numbers after rounding each value to the nearest hundredth are 56.21, 7.98, and 0.34.
When you round a number to a certain digit, you have to check the value of the digit before the place you want to round off to.
1. If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up.
2. If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down.
Here, the question said the nearest hundredth, so I had to look at the value in the thousandth place.
Here the numbers are,
56.213
Since the value in the thousandth place is 3 which is less than 5.
Hence round the number down.
56.21
7.983
Since the value in the thousandth place is 3 which is less than 5.
Hence round the number down.
7.98
0.344
Since the value in the thousandth place is 4 which is less than 5.
Hence round the number down.
0.34

Newton's first law of motion states that; An object continues to be in its state of rest or uniform motion unless acted upon by an external force in which case, it acts otherwise.
An example of this law is an orange placed on a table.
In essence, the orange continues in its state of rest unless acted upon by a force of push or otherwise by an individual or perhaps wind as the case may be.

Answer:
y = 1/3x + 2
Step-by-step explanation:
Slope - Intercept Form = y = mx + b
y - intercept = b = 2 (point of intersection of the y-axis)
m = slope
Slope = Change in Y/Change In X

what is the equation of the line in the slope-intercept? write your answer in simplest form.
Answer:
y=-6x
Step-by-step explanation:
Slope intercept form is y=mx+b where b is the y intercept and m is the slope. In this particular example, the y intercept is at (0,0), the origin, so b=0. y=mx+0 or just y=mx. Now, to determine the slope, we must look at the graph. It appears the graph intersects the point (-10, 60) as well as the point (0,0). Other than just calculating it quickly in your head, the way to get slope from that is y1-y2/x1-x2. Setting that up, 60-0/-10-0, which is 60/-10, which is equal to -6. Put that into the equation and you get y=-6x

Given info:- Evaluate: [(5/6 + 2/3) - (3/4 + 1/12)] and find the Evaluated form = ?
Solution:-
Given fractional expression: [(5/6 + 2/3) - (3/4 + 1/12)]
Take the LCM of denominator 3 and 6 is 6.
Again take the LCM of denominator 4 and 12 is 12.
so,
⟼ [(5+4)/6 - (9+1)/12]
⟼ [9/6 - 10/12]
Now, take the LCM of the denominator 9 and 12 is 36.
⟼ [(54-30)/36]
Now, reduce the fraction by extracting and cancaling out with 2.
⟼ [24÷2/36÷2]
⟼ 12/18
⟼ 6÷3/9÷3
⟼ 2/3
Answer↓
