How does number 3 work, I don’t understand how it end up being x+8
The answer is -5 = x. Because if x + 8 is 3 you would have to subtract 5 making the answer to X negative 5 + 8.
(01.07) Which of the following describes the correct process for solving the equation 3x + 6 = 21 and arrives at the corr O Divide both sides by 6 and then add 3. The solution is x = 5. Add 6 to both sides of the equation and then divide by 3. The solution is x = 9. O Subtract 6 from both sides of the equation and then divide by 3. The solution is x = 8. Subtract 6 from both sides of the equation and then divide by 3. The solution is x = 5.
Answer:
Subtract 6 from both sides of the equation and then divide by 3. The solution is x = 5.

¿Cuántas libras de café “La Finca” que se vende a $5 la libra debe mezclarse con 80 libras de
café común que se vende a $2 la libra, para hacer una mezcla que se venda a $3 la libra?
Answer:
Thew answer is "40 pounds".
Step-by-step explanation:
The value of x pound is $5
It's mixed with 80 pound
Formula:
[tex]\text{Average price} = \frac{\text{Rate of both}}{\text{weight of both}}[/tex]
Average price = 3
[tex]\to 3 = \frac{5\times x+ 2\times 80}{x+ 80}[/tex]
[tex]\to 3 = \frac{5x+ 160}{x+80}\\\\\to 3(x+80) = 5x+ 160 \\\\\to 3x+240 = 5x+ 160 \\\\\to 240-160 = 5x-3x \\\\\to 80 = 2x \\\\\to 2x=80 \\\\\to x=\frac{80}{2} \\\\\to x= 40[/tex]

what is 1/120 as a decimal
Answer:0.0083
Step-by-step explanation:
0.0083 is 1/120 as a decimal.
A decimal is a number that contain of a whole and a fractional part. Decimal numbers lie in the middle of integers and represent numerical value for quantities that are whole plus some part of a whole.
We get decimals when we smash a whole into smaller parts.
A decimal number then has two components: a whole number part and a fractional part. The decimal place value system for the whole part of a decimal number is the alike the whole number value system.
However, we obtain the fractional part of the decimal number as we move toward the right after the decimal point.
1/ 120 = 0.0083.
Therefore, 0.0083 is 1/120 as a decimal.

Quadrilateral ABCD is transformed to create A′B′C′D′. Match the coordinates of A′ with the transformations that create it. (2, 4) (2, 1) (6, 12) (4, -5) (-2, 4) (2, -4) (6, -12) (-4, 5) Quadrilateral ABCD is reflected over the x-axis. Quadrilateral ABCD is translated 2 units right and 1 unit down. Quadrilateral ABCD is dilated by a scale factor of 3. Quadrilateral ABCD is rotated 180° clockwise about the origin.
Answer:
The answer is below
Step-by-step explanation:
From the image attached, the coordinates of point A is at (2, -4).
Transformation is the movement of a point from its initial location to a new position. Types of transformation include dilation, reflection, translation and rotation.
If a point A(x, y) is reflected over the x axis, the new point is at A'(x, -y)
If a point A(x, y) is translated a units right and b units down, the new location is at A'(x + a, y - b)
If a point A(x, y) is dilated by factor of a, the new location is at A'(ax, ay)
If a point A(x, y) is rotated 180° clockwise about the origin, the new location is at A'(-x, -y)
Hence:
For Quadrilateral ABCD is reflected over the x-axis, the coordinates of A' is at A'(2, 4)
For Quadrilateral ABCD is translated 2 units right and 1 unit down, the coordinates of A' is at A'(4, -5)
For Quadrilateral ABCD is dilated by a scale factor of 3, the coordinates of A' is at A'(6, -12)
For Quadrilateral ABCD is rotated 180° clockwise about the origin the coordinates of A' is at A'(-2, 4).
Answer:
the coordinates of point A is at (2, -4).

find:
Find the perimeter of the triangle, in cm. What is the most efficient strategy you can find to solve this problem?
solution:
27, 35, and 32 are each the sum of a different pair of sides of the triangle
Then 27 + 35 + 32 is the sum of all three sides, each counted twice.
Thus, 27 + 35 + 32 = 94 is twice the perimeter
therefore,
the perimeter of the triangle is 94/2 = 47 cm.
Step-by-step explanation:
since the sides r of 2 triangles
actually perimeter = ans/ 2
perimeter of a triangle = sum of all sides/2
27+35+32/2 =94/ 2 = 47 ans

X/2 + 1 =7 .........
Answer:
x = 12
Step-by-step explanation:
x/2 + 1 = 7
Subtract both sides
x/2 + 1 - 1 = 7 - 1
x/2 + 0 = 6
x/2 = 6
Multiply both sides
x/2 * 2 = 6 * 2
x = 12
Use the Pythagorean’s theorem to calculate the length of the hypotenuse of a right triangle with 17 as the length and 15 as the width
Answer:
[tex]\huge\boxed{\text{Around\ \ } 23}[/tex]
Step-by-step explanation:
The Pythagorean Theorem states that
[tex]a^2 + b^2 = c^2[/tex]
Where [tex]a[/tex] is one leg of the triangle, [tex]b[/tex] is the other, and [tex]c[/tex] is the hypotenuse.
Since we know the legs and we need to find the hypotenuse [tex]c[/tex], we can substitute inside the equation with the values 15 and 17.
[tex]15^2 + 17^2 = c^2\\\\225+289 = c^2\\\\514 = c^2\\\\c = \sqrt{514}\\\\c \approx 23[/tex]
Hope this helped!
Answer:
Hypotenuse = 22.67
Step-by-step explanation:
[tex]a^2 + b^2 = c ^2\\[/tex]
a = One Leg
b = Another Leg
c = Hypotenuse
[tex]17^{2} + 15^{2} = c^2[/tex]
289 + 225 = [tex]c^2[/tex]
514 = [tex]c^2[/tex]
[tex]\sqrt{514} = c[/tex]
c = 22.67

Find the scale factor
Answer:
Scale factor: 2
Step-by-step explanation:
If you observe the side lengths of the larger shape, you'll notice that they are double the size of the original shape. Meaning, you have to multiply the smaller shape's side lengths by 2 to get the side lengths of the bigger shape.
So, the scale factor is 2.
