The required sum of -3x, 5x + y, and 7x - 8 - 3y in descending order is 9x - 2y - 8.
Simplification involves applying rules of arithmetic and algebra to remove unnecessary terms, factors, or operations from an expression. The goal is to obtain an expression that is easier to work with, manipulate, or solve.
Here,
To add -3x, 5x + y, and 7x - 8 - 3y, we can first combine like terms.
Group the x-terms together:
-3x + 5x + 7x = 9x
Group the y-terms together:
y - 3y = -2y
Group the constants together:
-8
Putting it all together, we get:
9x - 2y - 8
Therefore, the sum of -3x, 5x + y, and 7x - 8 - 3y in descending order is 9x - 2y - 8.

B. r > 1 7/8
C. r ≥ 1 1/8
D. r > 1 1/8
(The fractions are mixed numbers!!!!)
Answer:
the answer is C
Step-by-step explanation:
this is because he needs at least 1 1/2, it's already rained 3/8 inches, so to simplify the equation change 1 1/2 to 1 4/8 which is still equivalent to 1 1/2, then subtract 3/8 from 1 4/8 which will give you 1 1/8. now here is where it gets kind of tricky, both C and D seem to have 1 1/2, but the difference between them is the symbols > and ≥ are CRUCIAL!!!! (">" means that the number at the left is greater than the number at the right while "≥" means that the number at the left is greater than OR EQUAL TO the number at the right) so as you can see you also need to pay attention to what the text says, because it is mention quote on quote "Hector waters his lawn if it does not rain at least 1 1/2 inches each week," this means that if it's not at least (in other words the same as or more) 1 1/2 inches of rain a week, he will water his plants
Answer:
X=40, Y=140, Z=40 because total sum is 360
Answer:
x is 40° because it's same side interior angle
y is 140° because it's a corresponding angle with the 140° angle
z is 40° because it's a corresponding angle with x

a. -4
b. -6
C. 2.
Answer:
A. -4
Step-by-step explanation:
F(-1) means we must plug the number "-1" in for each x.
F(x) = x^2 + 3x - 2
F(-1) = (-1)^2 + 3(-1) - 2
= 1 - 3 - 2
= -4

An exteriorangle of ΔXYZ is ∠HXJ.
The correct option is D.
When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.
As per the provided diagram, the exterior angles in the ΔXYZ are:
∠LXH,
∠MXJ,
∠HXJ,
∠OYK,
∠GZN,
∠MXZ,
∠YXL,
∠KYZ,
∠GZY.
From the given choices, ∠HXJ is an exterior angle of ΔXYZ.

The area of a triangular painting is 50 in.² the base is 20 inches what is the height
The height of the triangle is 5 inches.
The region occupied by a triangle within its sides is known as the area of the triangle. The area of a triangle can be calculated by the calculating product of the base and height of the triangle with a half i.e 1/2. The formula for the area of the triangle is given by
Here we have
Area of the triangle = 50 in²
The base of the triangle, b = 20 inches
As we know,
Area of the triangle = 1/2 (base × height)
From the given data,
=> 50 = 1/2 (20 × height)
Multiply by 2 on both sides
=> 100 = (20 × height)
Divided by 20 into both sides
=> 100/20 = (20 × height)/20
=> 5 = height
=> height = 5 in
Therefore,
The height of the triangle is 5 inches.
