7th grade math help me please :))
Answer:
a) 23x
b) 8n
c) -6y
d) -17w
Explanation:
When combining like terms, if there is an addition operator, add both coefficients and carry the variable over. If there is a subtraction operator, subtract both coefficients and carry the variable over. Remember, you can only combine like terms if the variable, and exponent are the same. The addition and subtraction symbols are examples of an operator used in arithmetic. For example, 9x + 14x could be like adding 9 objects and 14 objects together, you have 23 objects total because 9 + 14 = 23. When you add negative numbers, it is like subtracting. When you subtract negative numbers, it is like adding. Negative just means opposite.
a) 9x + 14x = (9+14)x = (23)x = 23x
b) -2n - 10n = (-2+10)n = (8)n = 8n
c) 8y - 14y = (8-14)y = (-6)y = -6y
d) -6w - 11w = (-6-11)w = (-17)w = -17w
Answer:
a: 23x
b: 8n
c: -6y
d: -17w
Step-by-step explanation:
you just add/subtract the numbers then add the variable at the end
5(2x - 4) = 4x – 2

SOMEONE HELP ME WITH THESE TWO QUESTIONS! IM ALMOST DONE!
Answer:
m∠1=131
m∠2=49
Step-by-step explanation:
Remember that a line is 180 degrees. To find the measure of angle 2 you will take 180-131= 49.
The measure of angle 1 matches to 131 degrees since it is an alternate interior angle.
Find the slope of the line that passes through (-7, 1.3) and (-7, 14.2)
Answer:
The slope of the line that passes through (-7, 1.3) and (-7, 14.2) is undefined.
Step-by-step explanation:
Given the points
(-7, 1.3)(-7, 14.2)Finding the slope between (-7, 1.3) and (-7, 14.2):
It is clear that the value of x-coordinate remains the same, no matter what is the value of y is.
In other words, the given line is vertical.
i.e. [x₂ - x₁] = -7 - (-7) = -7+7 = 0
We know that the slope of a vertical line is undefined.
i.e.
Using the slope formula
Slope = [14.2 - 1.3] / [0]
Hence, the slope of the line that passes through (-7, 1.3) and (-7, 14.2) is undefined.

Archie's needs to Factor the polynomial at the Right x2+8x-9
A Both factors will use subtraction
B The second terms in the factor will have a sum of 8
C The second terms in the factors will have a product of -9
Answer:
It's A
Step-by-step explanation:
find the value of x.
Answer:
X= 20 degrees
Step-by-step explanation:
Because all the sides are the same length, we know this triangle is an equilateral triangle. In an equilateral triangle, all the angle measures are the same as well, and the sum of all the angles in a triangle is 180 degrees. So we have the equation:
(3x)3= 180
9x= 180
X =20

17x - y < 13
I’m slope-intercept form
Answer:
y > 17x - 13
Step-by-step explanation:
We want to write the inequality in slope-intercept form
The general slope intercept form is;
y = mx + b
where m is the slope and b is the y-intercept
So what we have to do to the inequality is to make y the subject
Thus, we have that;
17x -13 < y
Flipping this, we have
y > 17x-13

find m< AFE and include working out.
Answer:
∠ AFE = 80°
Step-by-step explanation:
Since BD is a straight line , then
∠ AFB + ∠ AFE + ∠ EFD = 180°, that is
50° + ∠ AFE + 50° = 180°
100° + ∠ AFE = 180° ( subtract 100° from both sides )
∠ AFE = 80°

Area of parallelogram
= Vertical height * Base
= (8m)(6m) = 48m².
The area is 48 square meters.
Answer:
48 square meters
Step-by-step explanation:
First we know there are two triangles the same size and because, the formula is A = 1/2b*h. Therefore, we only have to do the math for one triangle to make up for both triangles.
2*8=16.
Then because, 6 is for both the triangle and the square it would be 4*8=32
32+16=48
48
Therefore, your answer would be 48 square meters.
