Answer:

Step-by-step explanation:

[tex]\frac{-2}{3}-15.6+\frac{1}{4}x-15.6 = \frac{-2}{3}- 15.6 - 15.6 + \frac{1}{4}x\\\\ = \frac{-2}{3} - 31.2+\frac{1}{4}x\\\\= \frac{-2}{3}-\frac{31.2*3}{1*3}+\frac{1}{4}x\\\\= \frac{-2}{3}-\frac{93.6}{3}+\frac{1}{4}x\\\\= \frac{-95.6}{3}+\frac{1}{4}x[/tex]

Answer:

angle three is 30 degrees (depending on what kind of quadrilateral it is)

angle four is 150 degrees

Step-by-step explanation:

150+30

180 and if the other two are congruent meaning equal too

than they must also be 180 degrees in totale on the other side as well.

Answer:

A

Step-by-step explanation:

first I put 3 in for all the a's then I just completed the equation.

Answer:

it is A

Step-by-step explanation:

Answer:

c

Step-by-step explanation:

You can go ahead and emilminate a and d because there are no 4.6.Then you can emilminate b because the quartiles must be even and 4.7 and 6 are not even

Answer:

x is 23

Step-by-step explanation:

cause it is an 180 angle so 180-93=87

87 -18 =69

3x=69

x=23

Answer:

Step-by-step explanation:

in order to find x

(3x+18)° + 93°=180°

⇒3x+18=180-93

⇒3x=180-93-18

x=69/3

x=23

and there we go X = 23

hope it helps :)

have a great day!!

Answer:

Pounds of grapes: 11

Total cost: $8.97

Step-by-step explanation:

Because when you look at the prices, the last answer (Pounds of grapes: 11

Total cost: $8.97)is the most correct because it is adding by 2 (2, 4, 6, 8) every time. Its not exactly 8 but its the closet number :)

Answer:

15+25y= total cost

Step-by-step explanation:

this is easy

Answer:

25y + 15 = x

I think this is the answer, it does not say that lessons are paid for every day.

Answer: the answers are x = -292.5 and y = -122

Step-by-step explanation:

Elimination is combining equations to obtain an equation with just one variable. This is only possible if the coefficients of one variable in both equations are opposed and will cancel each other out when put together. Elimination is most effective when it occurs naturally in the equations, but equations may also be modified to produce typical coefficients by multiplying or dividing equations by a given value. The next step would be to utilize the equation we devised to determine the variable's worth and then insert that value back into the original equation to determine the remaining variable.

For solving the question to find x we have to make the coefficients of y the same. for that, we will multiply the first equation by 2.3 and the second equation by 2.5.

After that, we get the 2 equations as

2.3x-5.75y = 28.75

-2.5x+5.75y = 29.75

then by adding the 2 equations we get

-0.2x = 58.5

and by dividing 58.5 by -0.2 we get

x = -292.5

substituting the value of x in any equations above we get

y = -122

Answer:

Baby dinosaurs-12

Adult dinosaurs-4

Explanation:

15b+7a=208 where b- baby , a is adult

b=3a

Putting the values

15.3a+7.a= 208

45a+7a =208

52a=208

a=4

b=3a= 12
