Step-by-step explanation:
Answer:
x = -7
Step-by-step explanation:
3x + 6 = x - 8
-x -x
(subtract x from both sides)
2x + 6= −8
-6 -6
(subtract 6 from both sides)
2x = -14
/2 /2

Answer:
60
Step-by-step explanation:
45 is a vertical angle so the angle opposite will also be 45 degrees. There is also 75 in the bottom left corner of the trianlge. 45 + 75 is 120. In a triangle the angles all equal 180 degrees. subtract 120 from 180. 180-120=60.

Answer:
50
hope this helps
have a good day :)
Step-by-step explanation:
Answer:
D. 50
Step-by-step explanation:
∠CGF and ∠AFG add up 180° because they are same side interior angles. We can write an equation to model the situation:
m∠CGF + m∠AFG = 180°
And, we can substitute:
3x - 20 + x = 180
4x - 20 = 180
4x = 200
x = 50

QUESTION 2 PLEASE HELP ME!!!
Answer:
Look it up up
Step-by-step explanation:
The doctor has written an order for 350 mg of a particular drug. It is only available in a
liquid form. If each mL of the liquid contains 25 mg of the drug, how much of the liquid
will need to be given? Use dimensional analysis to set up the problem.
Answer:
14 mL
Step-by-step explanation:
because 1 ml = 25 mg we just need to divide 350 mg by 25 mg to know how many mL are equivalent to 350 mg.
350/25 = 14
therefore 14mL is equivalent to the 350 mg of the drug.
Hence, the liquid will need to be given is [tex]14ml[/tex] which is equivalent to the [tex]350[/tex] mg of the drug.
What is an equation?
The definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
Here,
[tex]1ml=25mg[/tex], here we need to divide [tex]350mg[/tex] by [tex]25 mg[/tex] to know how many [tex]ml[/tex]are equivalent to [tex]350 mg.[/tex]
i.e., [tex]\frac{350}{25}=14[/tex]
Therefore, 14mL is equivalent to the [tex]350[/tex] mg of the drug.
Hence, the liquid will need to be given is [tex]14ml[/tex] which is equivalent to the [tex]350[/tex] mg of the drug.

Rocco has 48.7 cups of flour in his storage unit. He needs 2/18 that amount to use for his homemade volcano. What is the total number of cups needed for his experiment?
Step-by-step explanation:
There are 48.7 cups in total
2/18 of 48.7 cups is needed for volcano
Total amount needed for experiments are :
2/18 of 48.7 = 97.4/18 = 5.411 cups
If Rocco has 48.7 cups of flour in his storage unit and He needs 2/18 of that amount to use for his homemade volcano then total number of cups needed for his experiment is 5.411
What is fraction ?fraction is a mathematical expression representing the division of one whole number by another
Here given that Rocco has 48.7 cups of flour in his storage unit. He needs 2/18 that amount to use for his homemade volcano.
Hence total number of cups needed for his experiment can be written as :
[tex]\frac{2}{18}\times \text{Total cups}[/tex]
[tex]\frac{2}{18}\times 48.7\\\\\\\frac{2}{180}\times 487\\\\\\\\\frac{974}{180}\\\\ = 5.411[/tex]

x=20 Ans
solve for x. Leave your answer in the simplest radical form.
Answer:
x = 2[tex]\sqrt{5}[/tex]
Step-by-step explanation:
'x' can represent the hypotenuse of a right triangle with a base of 4 (11-7) and a height of 2
use Pythagorean Theorem to find 'x':
2² + 4² = x²
4 + 16 = x²
x² = 20
x = [tex]\sqrt{20}[/tex]
x = [tex]\sqrt{4}[/tex]·[tex]\sqrt{5}[/tex]
x = 2[tex]\sqrt{5}[/tex]
