6-8x=7x-9x-36 i really need help
Answer:
Simplifying
6 + -8x = 7x + -9x + -36
Reorder the terms:
6 + -8x = -36 + 7x + -9x
Combine like terms: 7x + -9x = -2x
6 + -8x = -36 + -2x
Solving
6 + -8x = -36 + -2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2x' to each side of the equation.
6 + -8x + 2x = -36 + -2x + 2x
Combine like terms: -8x + 2x = -6x
6 + -6x = -36 + -2x + 2x
Combine like terms: -2x + 2x = 0
6 + -6x = -36 + 0
6 + -6x = -36
Add '-6' to each side of the equation.
6 + -6 + -6x = -36 + -6
Combine like terms: 6 + -6 = 0
0 + -6x = -36 + -6
-6x = -36 + -6
Combine like terms: -36 + -6 = -42
-6x = -42
Divide each side by '-6'.

How do you find the measure of angle A?
Answer:
m∠A = 18
Step-by-step explanation:
Formula:
the sum of the interior angles of a triangle is 180.
____________________
According to the formula :
[tex]m\angle A\ +\ m\angle B\ +\ m\angle C=180[/tex]
⇔ x - 22 + 3x + 19 + x - 17 = 180
⇔ 5x + (19 - 17 - 22) = 180
⇔ 5x + (2 - 22) = 180
⇔ 5x - 20 = 180
⇔ 5x = 180 + 20
⇔ 5x = 200
[tex]\Leftrightarrow x = \frac{200}{5} \\\Leftrightarrow x = 40[/tex]
Conclusion:
m∠A = x - 22 = 40 - 22 = 18

Answer:
27.2 m³
Step-by-step explanation:
Given:
Base edge = 4 mHeight = 5.1 metersFormula:
[tex](\text{Base edge})^{2} \times \dfrac{\text{Height}}{3}[/tex]
Replace the base edge and the height in the formula:
[tex]\implies (\text{4})^{2} \times \dfrac{\text{5.1}}{3}[/tex]
Evaluate the volume of the prism:
[tex]\implies (\text{4})(4) \times 1.7[/tex]

Tuesday he used 3/5 as many of 1/8
Answer:
19/40 = 0.475 You can use either the fraction or the decimal
Step-by-step explanation:
3/5 - 1/8 = 3 · 8/5 · 8 - 1 · 5/8 · 5 = 24/40 - 5/40 = 24 - 5/40 = 19/40
Answer:
[tex] \frac{3}{5} - \frac{1}{8} = \frac{19}{40} [/tex]
TOTAL:
=0.475
Step-by-step explanation:
3/5 - 1/8 = 3.8/5.8 - 1.5/8.5 = 24/40
- 5/40 = 24-5/40 - 24-6/40 =19/40
✿For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(5, 8) = 40. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 5 × 8 = 40. In the following intermediate step, it cannot further simplify the fraction result by canceling.

A company sells cocoa powder in a cylindrical container that is 5 inches long with a circular base of diameter 4 inches. The company is planning to sell a family-size product that will use similar packaging scaled by a factor of 2.
The circumference of the original container is (62.8, 15.7, 12.57, 6.28)
inches. This is (18.84, 9.42, 37.68, 12.57)
inches less than the circumference of the new container.
The circumference of the original container is 12.57 inches.
The cirucmference of the original container is 12.57 inches less than the circumference of the new container.
What is the circumference of the cylinder?The circumference of a cylinder is the distance round the cylinder. It is the perimeter of the cylinder.
The circumference of a cylinder = πD
Where:
π = 22/7D = diameterThe circumference of the original container = 22/7 x 4 = 12.57 inches
The circumference of the family sized container 12.57 x 2 = 25.14 inches
Difference in the circumference = 25.14 - 12.57 = 12.57 inches

A ladder 15 feet long leans against a house and makes an angle
of 60° with the ground. Find the distance from the house to the
foot of the ladder.
A 13 feet
)
B 7.5 feet
C 10 feet
D
8.2 feet
Answer:
B
Step-by-step explanation:
assume a right angle between the house and the ground.
then the ladder is the hypotenuse and distance from ladder to house is d
using the cosine ratio in the right triangle and the exact value
cos60° = [tex]\frac{1}{2}[/tex] , then
cos60° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{d}{15}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
2x = 15 ( divide both sides by 2 )
x = 7.5
distance from house to foot of ladder is 7.5 feet
