Solve using substitution. x + 2y = 4 and –4x − 7y = –9
Step-by-step explanation:
Given
x + 2y = 4
x = 4 - 2y.......... equation 1
-4x -7y = - 9.......equation 2
Putting equation 1 in equation 2
- 4 ( 4 - 2y) - 7y = - 9
-16 + 8y - 7y = -9
y = - 9 + 16
y = 7
Now
x = 4 - 2* 7 = 8 - 7 = 1
hope this helps.
Answer:
X=-10 y=7
Step-by-step explanation:
1) in first equation subtract 2y on both sides
X=4-2y
Substitute as "x" in the second equation:
-4(4-2y)-7y=-9
-16+8y-7y=-9
-16+y=-9
Y=7
Substitute y as 7 to get x)
X=4-2(7)
X=4-14
X=-10

An angle measures 30 degrees.
What is the measure of its complement (i.e., the complementary angle)?
The measure of the complimentary angle is 60 degrees.
Complimentary angle:The complimentary angle is the angle where the sum of angles should be 90 degrees
Since An angle measures 30 degrees.
So, the measure of an angle should be
= Sum of angles - one measurement of angle
= 90 - 30
= 60 degrees
Therefore we can conclude that The measure of the complimentary angle is 60 degrees.

three bags of chips costs m cents. At this rate, what is the cost, in cents, of one bag of chips?
Answer: m/3 cents
Step-by-step explanation:
Hi, to answer this question we have to divide the total cost of the chips (m) by the number of bags of chips (3).
Mathematically speaking:
Cost of one bag chip: m/3 cents
Since the total cost is represented by a variable, the individual cost is an expression.
If we replace the value of m by a number we will obtain the result as a number.

A similar scale model of the motorcycle shown stands 3 inches high and is 6 inches long. How high does the actual motorcycle stand?
Answer:
48 in.
Step-by-step explanation:
Scales are based on proportions. The proportion in this scenario is:
96/6 = x/3
Cross multiply. You are left with the equation:
96x3 = 6x
Simplify.
288 = 6x
288/6 = x
48 = x

A model's scale ratio is the proportionate ratio of dimensions. The actual motorcycle stands at a height of 48 inches.
What is the scale ratio?A model's scale ratio is the proportionate ratio of a linear dimension of the model to the equivalent characteristic of the original.
The length of the motorcycle is 96 inches, while the length of the scale model of the motorcycle is 6 inches. Therefore, the scale ratio can be written as,
[tex]\rm Scale\ Ratio = \dfrac{\text{The actual length of the motorcycle}}{\text{The model length of the motorcycle}}\\\\Scale\ Ratio = \dfrac{96}{6} = 16[/tex]
Using the same ratio the height of the motorcycle can be written as,
[tex]\rm Scale\ Ratio = \dfrac{\text{Actual height of the motorcycle}}{\text{Model height of the motorcycle}}\\\\\\16=\dfrac{\text{Actual height of the motorcycle}}{3}\\\\\\{\text{Actual height of the motorcycle}} = 16 \times 3 = 48\ inches[/tex]
Hence, the actual motorcycle stands at a height of 48 inches.

Find the slant height of the pyramid shown.
Answer:
B is the correct answer ( square root of ten)
Step-by-step explanation:
I just did it and got it right
The slant-height of the pyramid having perpendicular height as 3 units, base as 1 unit is : (b) √10.
A Pyramid is a three-dimensional geometric shape with a polygonal base and triangular faces that meet at a single point called the apex. The base can be any polygon, and the number of sides of the base determines the type of pyramid (e.g., a square base yields a square pyramid)
The "Slant-Height" of the given pyramid can be calculated by using Pythagoras-Theorem, which states that; (slant-height)² = (perpendicular)² + (base)²;
Substituting Perpendicular height as 3 units, base as 1 unit, and slant-height as "x";
We get,
⇒ 3² + 1² = x²,
⇒ x² = 9 + 1,
⇒ x² = 10,
⇒ x = √10,
Therefore, the slant-height is √10, option (b) is correct.

Which is the most efficient way to solve this equation?
x−57=135
A. Do nothing because the equation is already solved.
B. Subtract 135 from both sides of the equation so all terms will be on the same side of the equal sign.
C. Subtract 57 from 135 because x equals 78.
D. Add 57 to both sides of the equation because addition is the inverse operation of subtraction.
Answer: The Answer is D.
Step-by-step explanation: You are trying to get x by itself, and in order to do that, you need to get the 57 away from it. In order to do THAT, you need to do the opposite of what s already being done. Since your already subtracting it, in order to get it away from x, you need to add it to itself, and then add it to the other side, because what you do to one side, you do to one side, you must do to the other.
Find the degree of the monomial -4/9
Answer:
Step-by-step explanation: the degree is 0
Final answer:
The degree of the monomial -4/9 is 0 since it contains no variables and can be considered to have variables with an exponent of 0.
Explanation:
The degree of a monomial is the sum of the exponents of all its variables. In the case of the monomial -4/9, there are no variables present, which means that the degree is 0. This is because the monomial can be considered to have variables raised to the power of 0, and any number (except zero) raised to the power of 0 is 1, which does not affect the value of the coefficient (-4/9).

How do you find a coordinate on a graph?To identify the x-coordinate of a point on a graph, read the number on the x-axis directly above or below the point. To identify the y-coordinate of a point, read the number on the y-axis directly to the left or right of the point. Remember, to write the ordered pair using the correct order (x,y).
What is graph coordination?An ordered pair (x, y) represents a position of a point on a coordinate graph, where x is the number on the x-axis that the point lines up with and y is the number on the y-axis that the point lines up with. The numbers x and y in the ordered pair (x, y) are called coordinates.

Enter the value of b when the expression 8/9x+b is equivalent to 1/9 (8x+5)
Answer:
b = 5 / 9
Step-by-step explanation:
8/9x + b = 1/9(8x + 5)
Make b the subject of formula.
b = 1/9 (8x + 5) - 8/9x
Multiply through by 9
9b = 9 * 1/9 ( 8x + 5) - 9 * 8/9x
9b = 8x + 5 - 8x
9b = 5
b = 5 / 9
The value of b = 5 / 9

--------------------------------
1 3 0 3 The remainder is 3.
The remainder is -2
The remainder in synthetic division is the constant term of the quotient. To find the remainder of the synthetic division problem above, we can use the following steps:
Arrange the coefficients of the dividend and divisor in descending order of degree.
Set up the synthetic division table as follows:
2 -3 3 |1
---------------
1
Bring down the first coefficient of the dividend.
Multiply the coefficient we just brought down by the divisor and place the product in the next column.
Subtract the product from the corresponding coefficient of the dividend and place the difference in the next column.
Repeat steps 4 and 5 until we reach the last column.
The remainder is the last number in the bottom row of the synthetic division table.
Following these steps, we get the following synthetic division table:
2 -3 3 |1

A circle with area 9π has a sector with a central angle of 17π/9 radians. What is the area of the sector?
Answer:
8.5pi
Step-by-step explanation:
We can solve this problem with a rule of three.
The area of the whole circle is represented by a sector with central angle of 2*pi. So, if we want to find the area of a sector that has a central angle of 17pi/9, we can use the following logic:
sector of 2pi -> area equal to 9pi
sector of 17pi/9 -> area equal to X
2pi / (17pi/9) = 9pi / X
18 / 17 = 9pi / X
X = 17 * 9pi / 18 = 17pi / 2 = 8.5pi
