Answer:
a = -3
Step-by-step explanation:
3a - 6a + 2 = 8a + 20 - 5a
Combine Like Terms
-3a + 2 = 3a + 20
-2 -2
-------------------------------------
-3a = 3a + 18
-3a -3a
-------------------------------------
-6a = 18

-6 -6
a = -3
The area of a rectangle that has a length of 10 and a width of w.
Answer:
B
Step-by-step explanation:
To find the area, multiply length by width (lw, or l×w). If the length is 10, that just leaves the width, which is unknown. We can substitute 10 for l, which leaves us with 10w.

Solve the equation k+10=27 k=
Steps to solve:
k + 10 = 27
~Subtract 10 to both sides
k = 17
Best of Luck!
Can someone please help and solve
Answer:
C: x+y=27 and y=6+2x
Step-by-step explanation:
First part: If the sum of the two is 27, then it means that it is x + y = 27, because sum means addition.
Second part: The larger number (y) is 6 more than twice the smaller number (x). Twice a number means that it is that number multiplied by x, so it is 2x. 6 more means we add 6 to it so the second equation is y=6+2x.

Find the area of the given region using any method.
The best method would certainly be integration :)
The area is given by the integral,
[tex]\displaystyle\int_0^2\frac{\mathrm dx}{9-x^2}[/tex]
We can split up the integrand into partial fractions:
[tex]\dfrac1{9-x^2}=\dfrac16\left(\dfrac1{3-x}+\dfrac1{3+x}\right)[/tex]
Then the area is
[tex]\displaystyle\frac16\int_0^2\left(\frac1{3-x}+\frac1{3+x}\right)\,\mathrm dx[/tex]
[tex]=\dfrac16(-\ln|3-x|+\ln|3+x|)\bigg|_0^2[/tex]
[tex]=\dfrac16\left((\ln5-\ln1)-(\ln3-\ln3)\right)=\boxed{\dfrac{\ln5}6}[/tex]
Find the area of a triangle with a base of 27 ft and a height of 14 ft. 41 ft2 82 ft2 189 ft2 378 ft2
Answer:
The answer is 189 ft²Step-by-step explanation:
The area of a triangle can be found by using the formula
[tex]A = \frac{1}{2} \times bh[/tex]
where
b is the base
h is the height
From the question
b = 27 ft
h = 14 ft
Substitute the values into the above formula and solve
That's
[tex]A = \frac{1}{2} \times 27 \times 14 \\ = \frac{1}{2} \times 378 [/tex]
We have the final answer as
189 ft²Hope this helps you

bread for $8 each. The bakery eams, on average, $240 in revenue per day from the
sale of the French and multigrain breads.
Answer:
well if the breads both sell the same number of loaves for each type the you add 6 and 8 which is 14 divide it by 240 and you get ruffly 17 loaves per day.

express sin110 as ratio of acute angle
Answer:
sin70°
Step-by-step explanation:
Given sin110° where 110° is an obtuse angle in the second quadrant.
The related acute angle in the first quadrant is 180° - 110° = 70°
Thus
sin110° = sin70°

Find the coordinates of the point 3/10 of the way from A to B.
Answer:
[tex] (\frac{3}{13}, -3) [/tex]
Step-by-step explanation:
Apply the formula following formula to find the coordinate pair of the point that is 3/10 of the way from A(-3, -6) to B(11, 7):
[tex] x = \frac{mx_2 + nx_1}{m + n} [/tex]
[tex] y = \frac{my_2 + ny_1}{m + n} [/tex]
Where,
[tex] A(-3, -6) = (x_1, y_1) [/tex]
[tex] B(11, 7) = (x_2, y_2) [/tex]
[tex] m = 3, n = 10 [/tex]
Finding the x coordinate:
[tex] x = \frac{mx_2 + nx_1}{m + n} [/tex]
[tex] x = \frac{3(11) + 10(-3)}{3 + 10} [/tex]
[tex] x = \frac{33 - 30}{13} [/tex]
[tex] x = \frac{3}{13} [/tex]
[tex] y = \frac{my_2 + ny_1}{m + n} [/tex]
[tex] y = \frac{3(7) + 10(-6)}{3 + 10} [/tex]
[tex] y = \frac{21 - 60}{13} [/tex]
[tex] y = \frac{-39}{13} [/tex]
[tex] y = -3 [/tex]
The coordinates of the point 3/10 of the way from A to B are [tex] (\frac{3}{13}, -3) [/tex]

Answer:
Step-by-step explanation:
Step Statements Reasons
1. [tex]-6=-\frac{2}{3}(x+12)+\frac{1}{3}x[/tex] Given
2. [tex]-6=-\frac{2}{3}x-8+\frac{1}{3}x[/tex] Distributive property
3. [tex]-6=-\frac{1}{3}x-8[/tex] Combine like terms
4. [tex]2=-\frac{1}{3}x[/tex] Addition property of equality
5. -6 = x Multiplication property of equality
6. x = -6 Symmetric property
Answer:
To get from step 1 to step 2, apply the distributive property to eliminate the parentheses.
To get from step 2 to step 3, combine like terms on the right side of the equation.
To get from step 3 to step 4, apply the addition property of equality to isolate the variable term.
To get from step 4 to step 5, apply the multiplication property of equality to isolate the variable, x.
To get from step 5 to step 6, apply the symmetric property to rewrite the equation with the variable on the left side.
Step-by-step explanation:
Alex and leanardo went to the movies a drink cost $4.00 each and a bag of popcorn cost $ 5.00 each how many would they spend of they bouth 2 drinks and 2 Bags of popcorn
If Alex and Leonardo are both buying two bags of popcorn and drinks then the overall price would be $18.00.
$4.00 + $4.00 = $8.00 + $5.00 + $5.00 = $18.00
Therefore, they would spend 18 dollars.

what's the probability of pulling two red cards in a row from a deck of cards?
Hey there! I'm happy to help!
Let's say that we don't have jokers. In that case, there are 52 cards, and half of them are red (so 26 are red). The probability of pulling a red card once is 1/2 since half the cards are red.
If we pick one out, there are only 51 total cards left and 25 red cards. So, the probability of picking one again would be 25/51.
We multiply the probabilities of these two events to find the probability of them both happening.
1/2×25/51=25/102
The probability of picking two red cards in a row is 25/102 or around 24.5%.
