Write the equation 3x+2y=8 in general form. SHOW YOUR WORK PLEASE
Answer:
3x+2y-8=0
Step-by-step explanation:
The equation 3x+2y=8 in general form is 3x + 2y - 8 = 0 respectively.
What is a numerical expression?A numerical expression is an algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.
We are given that the equation 3x+2y=8.
The equation of straight line is written as y = mx + c
3x+2y=8.
2y = 8 - 3x
y = 8/2 - 3/2x
y = 4 - 3x/2
Hence, the general form is 3x + 2y - 8 = 0.

A.One solution?
B.No solution ?
Or
C.All solution?
Answer:
One solution, which is x=0.
Step-by-step explanation:
12(x-3)+18=6(x-3)
12x-36+18=6x-18
12x-18=6x-18
12x-6x-18=-18
6x-18=-18

Fred is 4 times as old as Nathan and is also 27 years older than Nathan.
Let f be Fred's age and let n be Nathan's age.
Which system of equations represents this situation?
Answer:
f = 4n
f = n+27
Fred is 36 years old and Nathan is 9 years old.
n = 9
Step-by-step explanation:
Answer:
Step-by-step explanation:
Ooh I love these type of problems
Okay, here we go :
f = Fred and n = Nathan
f = 4n
f = n + 27
Above are the two equations (the words translated into algebra)
Now you can solve using substitution (any method works, but substitution is easiest for this problem)
4n = n + 27
3n = 27
n = 9
Since n = 9 substitute n into either equation
f = 4 * 9
f = 36
Fred is 36 and Nathan is 9

A 5 KG curling rock slides along frictionless ice with a constant velocity of 10 m/s. what's the net force of the rock?
Answer:
0N
Step-by-step explanation:
Force = mass * acceleration
Given
Mass = 5kg
velocity = 19m/s
IF the velocity of the body is constant, then the acceleration will be zero.
Force = 5 * 0
Force = 0N
Hence the net force on the rock is 0N

a walking path BE in a park intersects intersects two sides of the park at their midpoints. You walk from point D to E, E to B, from B to C, and back to point D. How many yards did you walk?
Answer:
Total distance covered = 436 yards
Step-by-step explanation:
Walking path BE joins the midpoints B and E of the sides AC and AD.
By midsegment theorem,
"Line joining midpoints of two sides of a triangle is parallel and measure half of the third side"
m(BE) = [tex]\frac{1}{2}[m(CD)][/tex]
CD = 2(BE)
CD = 2(74) = 128 yd
From starting point D,
DE = 107 yd
EB = 74 yd
BC = [tex]\frac{254}{2}[/tex]
= 127 yd
CD = 128 yd
Total walking distance = DE + EB + BC + CD
= 107 + 74 + 127 + 128
= 436 yd
Total distance covered = 436 yards
Answer:
456
Step-by-step explanation:
107
74
254/2 =127
74x2=148
107+74+127+148=456

Mandy and Pete have a biased spinner numbered 1, 2, 3, 4, 5. They each want to find an estimate for the probability that the spinner will land on a 5. Mandy spins the spinner 20 times and records the number of times the spinner lands on a 5. Pete spins the spinner 200 times and records the number of times the spinner lands on a 5. Is Mandy or Pete more likely to get the better estimate? You must give a reason for your answer.
Answer:
Pete
Step-by-step explanation:
Given that:
Mandy's Estimate :
Number of spins , n = 20
Pete's Estimate:
Number of spins, n = 200
A good probability estimate is one which has narrow margin of error with a high degree of confidence. These two variables are affected by sample size.
A high sample size give a narrower margin of error and increases the confidence level probability
Based on the sample size used by each of Pete and Mandy, we can conclude that, Pete's probability estimate would be better due to its significantly higher sample size.

John waits on tables and is paid $8.00 an hour. In a 40-hour period, he earned $210.50 in tips. What were his total earnings?
a.) $530.50
b.) $1,684
c.) $520
Answer:
a.
Step-by-step explanation:
His total earning including tips of 210.50 dollars is a.) $530.50
What is an equation?An equation is written in the form of variables and constants separated by the operation of multiplication and division,
An equation states that terms in different forms on both sides of the equality sign are equal.
Multiplication and division do not separate the terms of an equation.
Given, John waits on tables and is paid $8.00 an hour. In a 40-hour period,
∴ His earning in those 40 hours is,
= (40×8) dollars.
= 320 dollars.
He also earned 210.50 dollars in tips.
∴ His total earnings is,
= (320 + 210.50) dollars.
= 530.50 dollars.
