Answer is 16 because 16/4 = 4 + -12 = -8
Answer:
m=16
Step-by-step explanation:
-8=m/4+(-12)
4=m/4
16=m
so first, you add 12 to the other side to cancel out the -12. 12-8=4. so now you have 4=m/4. to isolate the m, you have to multiply by 4 on both sides, which gives you 16=m or m=16.
i hope this helps :)

Answer:
KN ≈ 20.7 cm
Step-by-step explanation:
Using Pythagoras' identity in right triangle KLM to find KM
LM² = KL² + KM²
28² = 16² + KM²
784 = 256 + KM² ( subtract 256 from both sides )
528 = KM² ( take the square root of both sides )
[tex]\sqrt{528}[/tex] = KM
----------------------------------------
Using the sine ratio in right triangle KMN
sin64° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{KN}{KM}[/tex] = [tex]\frac{KN}{\sqrt{528} }[/tex] ( multiply both sides by [tex]\sqrt{528}[/tex]
[tex]\sqrt{528}[/tex] × sin64° = KN , that is
KN ≈ 20.7 cm ( to 1 dec. place )

why is the equation y = mx + b called the slope - intercept form?
Answers
Answer:
Step-by-step explanation:
The equation y = mx + b is called the slope-intercept form because both the slope and y-intercept are represented. The variable m, stands for slope, and the variable b, stands for slope.

Answer:
i believe the answer is 25.
Step-by-step explanation:
this is because if a=how much money deposited after t= depositing weekly and 16 is being multiplied by t. that leads me to believe she deposits $16 weekly. therefore, her original deposit was $25.
tell me if this is incorrect.
Answer:
25
Step-by-step explanation:
In this equation, the original deposit was 25 dollars. The equation shows how much total money was in the account every week. It is written in slope-intercept form, which is y=mx+b, where m is the slope (how much the account is increasing each week) and b is the y-intercept (what was in the account after 0 weeks). This means 25 dollars must be the initial deposit because it is the total before any new weekly deposits.
Ms. Murray has a collection of 25 dimes and nickels. How many nickels does Ms. Murray have if she has a total of $2.30?
Answers
because 1 dime=10¢ and so 21 x .10 = 2.10 and 1 nickel=5¢ so .05 x 4 = .20
2.10 + .20 = 2.30
I’m not sure if the explaining made sense but it’s 4 nickels :)

Joshua went to the grocery store and purchased cans of
soup and frozen dinners. Each can of soup has 200 mg
of sodium and each frozen dinner has 400 mg of sodium.
Joshua purchased a total of 10 cans of soup and frozen
dinners which collectively contain 2400 mg of sodium.
Write a system of equations that could be used to
determine the number of cans of soup purchased and
the number of frozen dinners purchased. Define the
variables that you use to write the system.
Answers
Answer:c + f = 10
200c + 400f = 2400
Step-by-step explanation:
Let's say c is the number of cans of soup and f is the number of frozen dinners.
The total number of items is 10:
c + f = 10
The total amount of sodium is 2400 mg. Each can of soup has 200 mg, and each frozen dinner has 400 mg.
200c + 400f = 2400
The problem doesn't ask you to solve the system, but I'll solve it anyway. We can use substitution or elimination. But first, simplify the second equation by dividing both sides by 200.
c + 2f = 12
Using elimination, subtract the first equation.
f = 2
Plug into either equation to find c:
c = 8
There are 8 cans of soup and 2 frozen dinners.
