Solve for X
3x + 4y = -16
X = 4y
Answers
Answer:
x = -4
Step-by-step explanation:
3x + 4y = -16
X = 4y
3(4y) +4y = -16
=> 12y + 4y = -16
=> 16y = -16
=> y = -1
3x + 4(-1) = -16
=> 3x -4 = -16
=> 3x = -12
=> x = -4

The math teacher gives each student a map of the amusement park that uses a coordinate plane. The meeting location is at (0, 0) on the map. Each unit is 100 feet. The first ride that you want to try is located at the coordinates (0, 4). The next ride is located at (3, 0). If you walked in a straight line from the first ride to the second ride, how many feet would you travel?
Answers
Answer:
500 ft
Step-by-step explanation:
use this formula
The actual distance between first and second ride is 500 ft.
What is Distance Formula?The distance between two point P(a, b) and Q(c, d).
so, the distance PQ = √(c-a)² + (d- b)²
Given:
Starting point = (0,0)
First ride = (0,4)
Second ride = (3,0)
In map, each unit = 100 ft
Using the distance formula
d = √( 3-0)² + (0-4)²
d = √9+ 16
d= √25
d = 5 units
So, the distance between first ride and second ride in the map is 5 units.
and,1 units = 100 ft
5 units = 500 ft
Hence, the actual distance between first and second ride is 500 ft.

The value of 3centimeters to kilometers is 0,00003 km
Converting centimeters to metersIn order to convert centimeters to kilometers, we will use the conversion factor below.
100cm = 1m
1000m = 1km
Given 3cm
3cm = 3/100 m
3cm = 0.03m
Convert to km
Since 1000m = 1km
0.03m = 0.03/1000
0.03m = 0.00003km
Therefore the value of 3centimeters to kilometers is 0,00003 km

4. Which of the following differences could not give a distance between two points on a number line? Explain why. a. 19-7 c. -12-(-7) b. -3 - (-18) d. 14-(-6)
Answers
-12 -(-7) could not be a distance.
Distance:
Distance traveled is the total length of the path traveled between two positions. It can either be a 0 or a positive number that's mean it can never be a negative number.
So from the above-given statement we have
a) 19-7 = 12 (which is positive number)
b) -12 - (-7) = -12 + 7 = -5 ( which is a negative number)
c) -3-(-18) = -3 + 18 = 15 ( which is a positive number)
d) 14-(-6) = 14 + 6 = 20 ( which is a positive number)
Therefore option b i.e., -12 - (-7) cannot be a distance between two points on a number line.

Team Z can do the work in 26 days, and working together Team Z and Y can do the same work in 14 days. How many days would it take for Y alone to do the work? Round your answer to the nearest whole number.
Answers
Answer:
30 days
Step-by-step explanation:
The above question is solved as shown below:
Working together Team Z and Y can do the same work in 14 days.
1/Team Y + 1/Team Z = 1/14 days
Team Z can do the work in 26 days,
Hence:
1/Team Y + 1/26 days = 1 /14 days
= 1/ Team Y + 1/26 = 1/14
1/Team Y = 1/14 - 1/26
The Lowest Common Denominator = 182
Hence:
1/Team Y = 13 - 7/182
1/Team Y = 6/182
Cross Multiply
Team Y × 6 = 1 × 182
Team Y = 182/6
Team Y = 30.33 days
Approximately to the nearest whole number = 30 days
Therefore, Team Y alone can do the job in 30 days

A phone shop sells iPhones and Samsung phones in a ratio of 7:5.
Last week the shop sold 42 iPhones.
How many Samsung phones did it sell?
Answers
Answer:
30
Step-by-step explanation:
Given the ratio 7 : 5
The 42 iPhones sold relates to the 7 part of the ratio.
Divide 42 by 7 to find the value of one part of the ratio.
42 ÷ 7 = 6 ← value of 1 part of the ratio, thus
5 parts = 5 × 6 = 30 ← number of Samsung phones sold
They sold 30 Samsung’s
Step-by-step:explanation:
If they sold 42 iPhones then skip count 7,14,21,28,35,42 and as you can see we skipped count 6 times so then just do 5 times 6 which will give u 30

Answers
Answer:
The identity property of addition
Step-by-step explanation:
Jamal uses the steps below to solve the equation 6x – 4 = 8.
Step 1: 6x – 4 + 4 = 8 + 4( Addition step of equality)
Step 2: 6x + 0 = 12
Step 3: 6x = 12 (Identity property of Addition)
Step 4: StartFraction 6 x Over 6 EndFraction = StartFraction 12 Over 6 EndFraction
Step 5: 1x = 2
Step 6: x = 2
The that property justifies Step 3 of his work is known as the identity property of addition.
The identity property of addition can be defined as when a given number x is added to zero, the result is we obtained x which is the given number itself.
