Answer:
Step-by-step explanation:
We are to choose all the equation that evaluates b to be 11. The following equations are true;
77 = 7b
To get b, we will divide both sides by 7
77/7 = 7b/7
11 = b
b = 11
This shows that the equation is correct since b = 11
Also 9 = b-2
To get b, we will add 2 to both sides of the expression
9+2 = b-2+2
11 = b
b = 11
This shows that the equation is correct since b = 11
Hence option C and D are correct
Answer:
C and D

Please solve for x as a fraction!
Answer:
the value of x is 5/7 which is in fraction
Answer: x = 5/7
Step-by-step explanation: 2x/3 + x/2 =5/6
To use a least common denominator, divide LCD by the original denominator and multiply the original numerator by the result.
for 2x/3 6÷3=2 2×2x=4x so that becomes 4x/6
for x/2 6÷2=3 3× (invisible) 1 = 3x, so that becomes 3x/6
combine 4x/6 + 3x/6 = 7x/6
Back to the original equation, substituting the calculated term:
7x/6 = 5/6 Multiply both sides by 6 to simplify (6)(7x/6) = (6)(5/6) 6's "cancel"
7x = 5 . Divide both sides by 7 to solve for x 7x/7 = 5/7
x = 5/7

What is the solution to this equation:
5x=35
Answer:
7
Step-by-step explanation:
5x = 35
Divide both sides by 5
x = 7
Whenever you have an equation like this, you have to simply divide both sides by the coefficient.

i edited the answer. hope it helps. if it isn't ryt tell me plz
Answer:
sin2x = [tex]\frac{30}{34}[/tex]
Step-by-step explanation:
Given
tanx = [tex]\frac{3}{5}[/tex] = [tex]\frac{opposite}{adjacent}[/tex]
This is a right triangle with legs 3 and 5
Let the hypotenuse be h , then using Pythagoras' identity
h² = 3² + 5² = 9 + 25 = 34 ( take the square root of both sides )
h = [tex]\sqrt{34}[/tex]
Thus
sinx = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{3}{\sqrt{34} }[/tex]
cosx = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{5}{\sqrt{34} }[/tex]
Hence
sin2x = 2sinxcosx = 2 × [tex]\frac{3}{\sqrt{34} }[/tex] × [tex]\frac{5}{\sqrt{34} }[/tex] = [tex]\frac{2(3)(5)}{\sqrt{34}(\sqrt{34}) }[/tex] = [tex]\frac{30}{34}[/tex]

I promise this the last one but how do you do these type of problems?
Answer:
0.96 + 0.43v
Step-by-step explanation:
You simplify, v and -0.57v are like terms, therefore you can add them together
v - 0.57v = 0.43 v
Answer:
0.96 + 0.43v
Step-by-step explanation:
What you are doing is combining like terms. Let's say v is candy I have v - .57v that means I have one candy and I ate .57 of it already so we subtract to get .43v and the .96 is brussel sprouts. We do NOT want to mix the candy and the brussel sprouts because they are different things.
If you need me to explain more let me know, but hopefully this helps and have a great day!

For field trip the school bought 47 sandwiches for $4.60 each and 39 bags of chips for $1.25 each how much was spent on sandwiches
Answer: 216.2 + 48.75 = 264.95
Step-by-step explanation:
Multiply the amount of sandwiches by the cost.
47 * 4.60 = 216.2
Multiply the amount of chips by the cost.
39 * 1.25 = 48.75
Add them the totals together.
216.2 + 48.75 = 264.95
