Answer:

m<b= 88º

m<C=44º

m<A=48º  (given)

Step-by-step explanation:

180=48+x+x-44

180=4+2x

176=2x

x=88

x-44=44

Answer:

∠A = 48°

∠B = 88°

∠C = 44°

Step-by-step explanation:

We know that the angles in a triangle, added together, equal 180°. Because of this information, we can know that angle A, plus angle B, plus angle C should come out to a total of 180°.

So, how can we represent this using algebra? It should look like this:

[tex]48+x+(x-44)=180[/tex]

Now, it shouldn't be that hard to solve for x. My steps are shown below:

[tex]48+x+(x-44)=180\\48+x+x-44=180\\x+x+48-44=180\\2x+4=180\\2x=176\\x=88[/tex]

Now we know what x is equal to, and we can find the measure of each angle. Angle A we already know the measure of, it's 48°. Angle B has a measure of x, and we know x is equal to 88°. Angle C is equal to x - 44, which is equal to 88 - 44, or 44°.

Hopefully that makes sense! If you have questions, let me know. :)

Answer:

AB = BC = AC = 15

Step-by-step explanation:

Since the triangle is equilateral then the 3 sides are congruent.

Equate any 2 sides and solve for x , that is

AC = AB , so

11x - 7 = 6x + 3 ( subtract 6x from both sides )

5x - 7 = 3 ( add 7 to both sides )

5x = 10 ( divide both sides by 5 )

x = 2

Then

AC = 11x - 7 = 11(2) - 7 = 22 - 7 = 15 , thus

AB = BC = AC = 15

36

Step-by-step explanation:

12+12+12

Another Explanation:

Lets say you Have 12 cookies and your mom buys you 12 more then next day Your dad Buys You 12 more! You havent Ate any But, You wanted to Know how much You Have in Count.

So you Add 12+12+12

Which equals to 36 Cookies!

Thats a lot of cookies Haha!

Step-by-step explanation:

In a rectangular prism, the cross-section is always a rectangle.

In a triangular prism, each cross-section parallel to the triangular base is a triangle congruent to the base.

Answer:

Step-by-step explanation:

Lets name the 3 families Family A, Family B, and Family C. Now, they decided to divide the giant 220-ounce container into 3 different families. We need to divide 220 by 3 to find out how many ounces will one family get.

Step 1: Divide

=> 220 ÷ 3

=> 73.333

So, each family will receive 73.333 ounces. I hoped this helped.

B-The distribution is approximately Normal, with a mean of 128 messages and a standard deviation of 30 messages.

Step-by-step explanation:

Answer:

1.17B

Step-by-step explanation:

Katie and her friends will pay 17% of the bill, B.

Therefore, we have to add 17% of B to B to find how much they will pay:

17/100 * B = 0.17B

Therefore, the total bill will be:

Bill + tip

= B + 0.17B = 1.17B

The expression that represents the total bill they will pay is 1.17B

Answer:

[tex]m=-4; (2,8)[/tex] is on the line [tex]y=-4x+16[/tex]

Step-by-step explanation:

To find the answer we use the slope-intercept formula

[tex]y=mx+b[/tex]

Answer/Step-by-step explanation:

"Side AB is parallel to side DC so the alternate interior angles, angle ABD and angle CDB, are congruent." True

"Side AB is equal to side DC and DB is the side common to triangles ABD and BCD."  True

Now we have 2 triangles, with 2 congruent sides, and the angles between these pairs of congruent sides, are also congruent..

This means that:

Therefore, the triangles ABD and CDB are congruent by SAS postulate, NOT SSS postulate, which would require 3 pairs of congruent sides.

Answer: Triangles ABD and CDB are congruent by the SAS postulate.

Step-by-step explanation:

The Amount that Jenny wants to earn = $1300

The Amount that she already has = $127.05

In order to know the amount that she'll need more in order to meet her goal, we simply have to subtract the amount that she already has from the total amount that she needs.

Step-by-step explanation:

Answer:

No solution

Step-by-step explanation:

Here you're given a system of two linear equations.  It seems as though your goal is to solve this system for x and y, using the substitution method.

Start by setting y = -3x + 4 equal to y = 3x - 2.  This eliminates y.  But it leaves you with 4 = -2, which is always false.  Thus, the given system has no solution.  If you were to graph the two lines, you'd see that they are parallel and never intersect.

Answer:

No, no es

Step-by-step explanation:

Answer:  Yes they are all on the same line.

Step-by-step explanation:

We can find an equation between two of the points and check to see if the third point is also a solution.  I'll pick (1,3) and (-2,4) and calculate a slope:

y = (4-3) = 1

x = -2 - 1 = -3

slope = y/x

slope = -1/3 or -0.3333

The equation, so far, is:

y = -(1/3)x + b

We can find b by entering one of these points into the equation and solving for b.  I'll pick (-2,4):

y = -(1/3)x + b

4 = -(1/3)(-2) + b

4 = (2/3) + b

b = 3 1/3 or 10/3

The equation is

y = -(1/3)x + 10/3

This equation goes through the two points we used to cacluate the slope.  The third point, (4,2) can be checked to see if the equation gives us a y value of 2 if we set x=4:

y = -(1/3)x + 10/3

y = -(1/3)*(4) + 10/3

y = -(4/3) + 10/3

y = 6/3 or 2

It correctly returns a value of 2, so (4,2) is also on this line.

Step-by-step explanation:

Normally we write equation of functions like this: f(x) = x - 5

When we say f(5) = 7, we are implying that the x is 5.

The equation could look something like this: f(x) = x + 2

In this case, if you put x as 5, you will get 7 or 5 + 2

Means that 5 times of f equals to 7

Answer/Step-by-Step-Explanation:

Yes, She is Correct Because It say " Yesterday, the movie theater brought in $1,440 in ticket sales and $295.25 in food sales" and then it say Today ticket sales were 3/4 as much as yesterday..

So the key Numbers are:

$1,440 and 295.25 and 3/4

Then it say food say went down by $33.50

the Key Words are "Went Down" Meaning -$33.50

Therefore 3/4 · (1440)+295.25+(-33.50)

Hence, Nina is Correct.

(Ask If Answer to 3/4 · (1440)+295.25+(-33.50)  Needed)

Answer:

Step-by-step explanation:

Nina is correct. Her expression represents the scenario because it takes ¾ of the ticket sales and subtracts $33.50 from the food sales.

Answer:

Step-by-step explanation:

[tex]15) f(x) = 10-\dfrac{9}{2}x\\10-\dfrac{9}{2}x = -53\\\\-\dfrac{9}{2}x=-53-10\\\\\dfrac{-9}{2}x= - 63\\\\x = -63*\dfrac{2}{-9}\\\\x = 7*2\\\\x = 14[/tex]

[tex]17) \dfrac{1}{8}y = \dfrac{-3}{4}x - 1\\\\Multiply \ the \ entire \ equation \ by \ 8\\\\8*\dfrac{1}{8}y=8*\dfrac{-3}{4}x-1*8\\\\\\y = 2*(-3)x-8\\\\y = -6x - 8\\\\6x + y = -8\\[/tex]

[tex]18) 5y = 35 + 10x\\\\\dfrac{5y}{5}=\dfrac{35}{5}+\dfrac{10x}{5}\\\\y = 7+2x\\\\-2x + y = 7\\\\[/tex]

[tex]19)x -4y = 28\\\\ -4y = -x + 28\\\\\dfrac{-4y}{-4}=\dfrac{-x}{-4}+\dfrac{28}{-4}\\\\\\y = \dfrac{1}{4}x-7[/tex]

x = 0 ; y = 0 - 7 = -7          (0 .-7)

[tex]x = 4 ; y = \dfrac{1}{4}*4-7 = 1 - 7 = -6 ; (4 , -6)\\\\\\x = -4 ; y = \dfrac{1}{4}*(-4) - 7 = -1 - 7 = -8 ; (-4,-8)[/tex]

Step-by-step explanation:

to do this you just need to work through the maths, Eg simplify 12/6 to 2 and cancel the (x-2) this will give you an answer of 2(x-2) / X=5
