9(m-3)+3m=7m+43 what is the answer
Answer:
9(m - 3) + 3m = 7m + 43
=>9m - 27 + 3m = 7m + 43
=> 12m - 27 - 7m = 43
=> 5m - 27 = 43
=> 5m = 70
=> m = 70/5 = 14
Answer:
m=14
Step-by-step explanation:
start with your parenthesis and multiply 9 to m-3 which makes that 9m-27+3m=7m+43
add your m together making that 12m-27=7m+43
add 27 to both sides equalling 12m=7m+70
subtract 7m from both sides resulting in 5m=70
divide both sides by 5 equalling m=14
Find the distance between the points (2,0) and (-4,6)
Answer:
let's see what to do buddy...
Step-by-step explanation:
We have this equation to find the distance between two points :
a = ( 2 , 0 ) and b = ( -4 , 6 )
[tex]distance = \sqrt{ {( \: y(b) - y(a) \: })^{2} + ( \: {x(b) - x(a)} \: )^{2} } \\ [/tex]
Now just need to put the coordinates in the equation :
[tex]distance = \sqrt{ ({6 - 0})^{2} + ({ - 4 - 2})^{2} } \\ distance = \sqrt{ {6}^{2} + ({ - 6})^{2} } = \sqrt{36 + 36} \\ distance = \sqrt{36 \times 2} = 6 \sqrt{2} [/tex]
And we're done.
Thanks for watching buddy good luck.

Answer:
The Answer is A I'm positive
Answer:
The answer is option AStep-by-step explanation:
[tex] \frac{2}{3} x - 1 = 4 \\ [/tex]
Move 1 to the other side of the equation
That's
[tex] \frac{2}{3} x = 4 + 1 \\ \frac{2}{3} x = 5[/tex]
Multiply through by 3 to eliminate the fraction
We have
[tex]3 \times \frac{2}{3} x = 5 \times 3 \\ 2x = 15[/tex]
Divide both sides by 2
[tex] \frac{2x}{2} = \frac{15}{2} \\ [/tex]
We have the final answer as
[tex]x = \frac{15}{2} \\ [/tex]

Lila's office had already recycled 3 kilograms this year before starting the new recycling plan, and the new plan will have the office recycling 2 kilograms of paper each week. Write an equation that shows the relationship between the weeks x and the paper recycled y. Write your answer as an equation with y first, followed by an equals sign.
Answer:
y = 2x + 3
Step-by-step explanation:
Based on the information provided we can use the values to write a proper algebraic equation like the following one ...
y = 2x + 3
The equation above states that the total number of paper that is recycled is equal to the 2 kilograms that are being recycled on a weekly basis plus the 3 kilograms that have already been recycled. This means that the value of y depends on the input given for the value of x which is the number of weeks that have passed.

Answer:
s = 0.3m
Step-by-step explanation:
Given that s varies directly with m then the equation relating them is
s = km ← k is the constant of variation
To find k use the condition
s = 9 when m = 30
9 = 30k ( divide both sides by 30 )
[tex]\frac{9}{30}[/tex] = k
s = [tex]\frac{9}{30}[/tex] m or
s = 0.3m ← equation of variation

In a right triangle, one leg (a) is 10 cm, and its hypotenuse (c) is 26 cm. Find b?
Answer:
[tex]\boxed {\tt b=24 \ centimeters}[/tex]
Step-by-step explanation:
This is a right triangle, so we can use Pythagorean Theorem.
[tex]a^2+b^2=c^2[/tex]
a and b are the legs, while c is the hypotenuse.
One leg is 10 centimeters. The hypotenuse is 26 centimeters. Therefore,
[tex]a= 10 \ cm \\c= 26 \ cm[/tex]
[tex](10 \ cm )^2+b^2=(26 \ cm)^2[/tex]
Solve the exponents.
(10 cm)²= 10 cm * 10 cm= 100 cm²[tex]100 \ cm^2+b^2=(26 \ cm)^2[/tex]
(26 cm)²= 26 cm * 26 cm= 676 cm²[tex]100 \ cm^2+b^2=676 \ cm^2[/tex]
Subtract 100 from both sides of the equation.
[tex]100 \ cm^2- 100 \ cm^2+b^2=676 \ cm^2- 100 \ cm^2[/tex]
[tex]b^2=676 \ cm^2 - 100 \ cm^2[/tex]
[tex]b^2= 576 \ cm^2[/tex]
Take the square root of both sides of the equation.
[tex]\sqrt{b^2} =\sqrt{576 \ cm^2}[/tex]
[tex]b=\sqrt{576 \ cm^2}[/tex]
[tex]b= 24 \ cm[/tex]
The other leg of the triangle is equal to 24 centimeters.

Let q(t) = 29t and r(t) = t/29. Which method could be the first step in proving that q(t) and r(t) are inverse functions?
Replace the t in the expression for q(t) with t/29, and replace the t in the expression for r(t) with 29t.
Replace the 29t in the expression for q(t) with t, and replace the t/29 in the expression for r(t) with t.
Replace the t in the expression for q(t) with 29t, and replace the t in the expression for r(t) with t/29.
Replace the 29t in the expression for q(t) with t/29, and replace the t/29 in the expression for r(t) with 29t.
Answer:
Replace the t in the expression for q(t) with t/29, and replace the t in the expression for r(t) with 29t.
Step-by-step explanation:
Given q(t) = 29t and r(t) = t/29, to show that q(t) and r(t) are inverse of each other, we can simply find q(r(t) and r(q(t))
To find q(r(t):
q(r(t)) = q(t/29)
q(t/29) is gotten by replacing t in q(t) with t/29 as shown;
q(t/29) = 29(t/29)
q(t/29) = 29t/29
q(t/29) = t
Also for r(q(t)):
r(q(t)) = r(29t)
r(29t) is gotten by replacing t in r(t)/with 29t as shown;
r(29t) = 29t/29
r(29t) = t
Since r(q(t)) = q(r(t)) = t, this shows that they are inverses of each other.

50
Step-by-step explanation:
you just subtract the 29 from 79
There are 50 candies left in the jar.
What is mean by Subtraction?
Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Given that;
There are 79 candies in the Jar.
Aaron remove 29 candies from the jar.
Now,
Total number of candies in the jar =n 79
And, Aaron remove 29 candies from the jar.
