Use addition to solve the system of linear equations. Include all of your work in your final answer.
Answer: No solutions
Step-by-step explanation:
You can either use substitution or elimination
You can plug in y to the first equation to get x-(x-4)=6 to get 4=6 which is not possible so no solutions
Jacob has 17 yards of fabric. He uses 1 third of it to make a cape. How many yards of fabric does Jacob use for the cape? Solve on paper. Write your answer as a mixed number. 17 yards ? Jacob uses yards of fabric for the cape
Answer:
The mixed number is 5 2 ÷ 3
Step-by-step explanation:
The computation of the number of yards of fabric does Jacob use is shown below:
Given that there is 17 yards of fabric
And, it used one third of it
So the number of yards would be
= 17 ÷ 3
= 5 2 ÷ 3
Hence, The mixed number is 5 2 ÷ 3

En un día de febrero, una ciudad de Estados Unidos registró una temperatura mínima de 9° bajo cero y una temperatura máxima de 13°C. ¿De cuántos grados fue el intervalo de temperaturas registradas?
Answer:
La cantidad de grados del intervalo de temperaturas registradas en el día de febrero mencionado es de:
5Step-by-step explanation:
En estadística, cuando se utilizan intervalos como valores para identificar datos cuantitativos, como en este caso temperaturas registradas, deben tomarse todos los valores, en este caso enteros, desde el límite inferior (temperatura mínima) hasta el límite superior (temperatura máxima), por lo cual no se puede restar el valor máximo al valor mínimo, sino que debes identificar todos los valores y después contarlos. En el caso del ejercicio dado, los grados en el intervalo mencionado son:
9°C10°C11°C12°C13°CComo puedes ver, los grados en el intervalo de temperaturas registradas serían 5.
What is the y-intercept of the function below?
y= 2x + 7????
Answer:
(0,7)
Step-by-step explanation:
This equation is already in slope-intercept form, (y=mx+b), where m is the slope, and b is the y-intercept.
From the equation, we see that (0,7) is the y-intercept.

A piece of wood is cut into three different sized pieces. The ratio of the three pieces is 4:5:6. If the actual length of the wood is 45 inches, then what is the length of the short side?
Answer:
12
Step-by-step explanation:
So 4:5:6 = 45
4+5+6 = 15
45/15 = 3
Since 4 is the smallest, 4*3 = 12.
Hope this works!
Answer:
Step-by-step explanation:
This is a question worth knowing how to do. It is prime candidate for a test question.
Equation
Let the unit be x
therefore
4x + 5x + 6x = 45
Solution
15x = 45
x = 45/15
x = 3
The shortest piece is 4*3 = 12
The middle piece = 5*3 = 15
The longest piece = 6*3 = 18
Total 45

James has x merit points.
Sarah has three times as many merit points than James.
Robert has 68 fewer merit points than James.
ETTER

Each merit point is worth 3 pence.
All three of the students have a total of £15.81
EFFECT
Work out how many merit points each student has.
Irk
James:
Your
Marks
Sarah:
Robert
Answer:
James = 119 points
Sarah = 357 points
Roberts = 51 points
Step-by-step explanation:
Given that :
James = x points
Sarah = 3x points
Roberts = x - 68 points
Each point = 3 pence
All students have a total of £15.81
1 pound = 100 pence
£15.81 pound = 1581 pence
3x + 3(3x) + 3(x - 68) = 1581
3x + 9x + 3x - 204 = 1581
15x - 204 = 1581
15x = 1581 + 204
15x = 1785
x = 1785 / 15
x = 119
Hence,
James = 119 points
Sarah = 119 * 3 = 357 points
Roberts = 119 - 68 = 51 points

What is division?The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.
Given:
Simone is buying pies for a party.
One cherry pie costs $7,
and one apple pie costs $5.
If Simone needs to buy at least 18 pies and has no more than $110 to spend,
the maximum number of cherry pies,
= 110/7
= 15.71.
If 15 cherry pies, then 3 apple pies.
The total amount = 15 x 7 + 3 x 5
= 110

Ir (2p-1,p) is a solution of the equation 9y + 12 = 10x, then find the value of p
Answer:
p = 2
Step-by-step explanation:
Since, (2p-1,p) is a solution of the equation 9y + 12 = 10x.
Therefore, plug x = 2p - 1 & y = p in the above equation.
9p + 12 = 10(2p - 1)
9p + 12 = 20p - 10
12 + 10 = 20p - 9p
22 = 11p
p = 22/11
p = 2
