3x + 2y=11 // 2x - 2y = 14 solve I substitution method
Answers
Hey there! I'm happy to help!
To solve by substitution, rearrange one of the equations for one of the variables.
3x+2y=11
Subtract 2y from both sides.
3x=11-2y
Divide both sides by 3.
x=11/3-2/3y
Now we plug this value of x into the second equation to solve for y.
2(11/3-2/3y)-2y=14
We use distributive property to undo the parentheses.
22/3-4/3y-2y=14
We combine like terms.
22/3-10/3y=14
We subtract 22/3 from both sides.
-10/3y=20/3
Divide both sides by -10/3.
y=-2
We plug this value into one of the equations to solve for x.
3x+2(-2)=11
3x-4=11
Add 4 to both sides.
3x=15
Divide both sides by 3.
x=5
So, the solution is x=5 and y=-2 or (5,-2).

DeAnna had $23 to spend on two pencils. After buying them she had $17.
How much did each pencil cost?
Answers
Answer:
$3
Step-by-step explanation:
23-6=17 well 6÷2=3 so that means that it equals $3
Explanation:
First, your gonna wanna subtract the amount she had before, minus how much she has now.
23
-17
——
6
Next, you should’ve got a difference of 6. Your gonna wanna divide that by two because remember she said she wanted TWO pencils.
6÷2= 3
Lastly, based on the answer you got you should know that it...
It cost $3 for each pencil.
Always make sure to add the dollar sign back ♡

The product of a number and 7 decreased by 2
Answers
Answer:
(x× 7) -2
Step-by-step explanation:
(x× 7) -2
product of # = x
and 7 means to multiply
decreased by two means -2
Answer:
the product of a number and seven decreased by two is 7x-2
Step-by-step explanation:
a "product" is the answer to a multiplication problem. instead of writing a multiplication symbol (x) we can simply put the variable next to the number it is being multiplied to. (7x) so, a number (which can be written as any letter, since we don't know the exact number- it's a variable.) 7x decreased by 2 means subtracting. so, we get 7x-2.

Latoya created a factor tree and wrote the prime factorization of 90 shown below. A factor tree of 90. 90 branches to 9 and 10. 9 branches to 3 and 3. 10 branches to 2 and 5. The equation is 90 = 2 times 3 times 5. What is Latoya's error? She should not have found the factors of 9. She should have included an exponent of 2 on the 3.

The product of eight and a number x
Answers
Answer:
To write this down as an algebraic expression you would simply need to multiply the two terms together.
So in this case it would be 8 multiples by x which is 8x
Step-by-step explanation:
1) Find out the variables in the Expression
2) Find the operation that is done to the variables
3) Apply the operation to those variables.
The product of 8 and an unknown number x is 8x.
What is multiplication?Multiplication gives us a resultant number that will be very big as compared to the number which is going to be multiplied if and only if the number which is going to be multiplied is more than one.
Given the product of 8 and x
Product is also called multiplication.
Multiplication is an arithmetic operator which is applied in between two numbers or variables.
For example 2 × 4, 4 × 5.
So,
Product of 8 and x must be
8 × x = 8x
Hence "The product of 8 and an unknown number x is 8x".

Robert had $58.62 in his bank account. He got paid $142.76. He then bought a new jacket for $63.76. He also bought 2 new movies for $6.99 each. He then babysat for his sister and was paid $12. How much money does Robert have now?
Answers
Robert then decides to buy a new jacket that costs $63.76 which means he made a withdrawal from his account of $63.76
So you would now subtract the total in his bank account from the cost of the new jacket. This leaves him with $137.62 left in his bank account.
Next Robert bought two new movies, which each cost $6.99 and so because he bought two movies, you multiple $6.99 by two. This comes out to $13.98 which is the amount Robert paired to purchase the two new movies. Robert withdrew the $13.98 from his bank account, leaving him with $123.64 left in his bank account.
Finally, Robert is paid $12 for babysitting his younger sister. He adds this to his bank account, which means his bank account total is $135.64
This means that Robert now has $135.64 in his bank account.
Hope this helps :)

The definition of parallel lines requires the undefined terms line and plane, while the definition of perpendicular lines requires the undefined terms of line and point. What characteristics of these geometric figures create the different requirements?
Answers
Answer:
Parallel lines requires the terms line and plane because line and plane that are parallel cannot cross each other therefore they will never make a point of intersection. The characteristics of that parallel lines consists of lines and planes. Perpendicular lines requires the terms line and point because whenever two lines intersect, it creates a point and whenever two planes intersect, it creates a line. The characteristics of that perpendicular lines are points and lines.
The characteristics of the geometric figures that create the different requirements are;
Parallel lines are lines on the same plane and that are equidistant from each otherPerpendicular lines are lines that form a 90 degree angle at the point of their intersection.Reasons:
The characteristics of parallel lines are;
The shortest distance between the lines that are parallel is the same at all points along the lines.The lines are on the same plane.As the plane is extended indefinitely, the lines do not intersect.The characteristics of perpendicular lines are;
Perpendicular lines are lines that intersect at a point.Where two lines are perpendicular, the slope of one line is the negative reciprocal of the other, such that the product of the slopes of two lines that are perpendicular is -1.The angle formed at the intersection of perpendicular lines is 90°.An horizontal and a vertical line on the same plane are perpendicular to each other.Therefore, the characteristics of the geometric figures that create the different requirements are;
Parallel lines are lines on the same plane.Perpendicular lines are lines that form a 90 degree angle at the point of their intersection.Learn more about parallel and perpendicular lines here:

What was the temperature at 10 PM? Explain how the number line helped you
find your answer.
Answers
Answer: - 1°F
Step-by-step explanation:
Given that:
At 8a.m:
Temperature = 3°F below 0
By 1p.m ; Temperature rose by 14F ;
By 10pm ; temperature dropped by 12F
Temperature at 10 pm:
3°F below 0 = - 3°F
Temperature at 1pm: temperature increased by 14°F
-3°F + 14°F = 11°F
Temperature at 10pm: temperature dropped by 12°F
11°F - 12 = - 1°F
