A. 3x − 7 = −19; x =

Answers

Answer 1

Answer:

x =-4

Step-by-step explanation:

3x − 7 = −19

Add 7 to each side

3x − 7+7 = −19+7

3x = -12

Divide by 3

3x/3 = -12/3

x =-4

Answer 2

Work it backwards: -19+7=-12 so that means we do -12/3 next and it equals -4, so your answer is x=-4

Circumference of the circle= 3.14 * 5

=15.7 cm

Answer:

[tex]\huge{\boxed{\sf{15.71 cm}}}[/tex]

Step-by-step explanation:

Given :

diameter ( d ) = 5 cm

radius ( r ) = [tex]\frac{5}{2}[/tex] = 2.5 cm

Finding the circumference of a roll of tape:

Circumference of a circle = 2πr

circumference = [tex]2 * \frac{22}{7} * 2.5[/tex]

circumference = 15.71 cm

select all coordinate pairs that could represent a solution to 3x - 2y = 12

Answers

So you just need to find the pairs that work in when you substitute them in, we can go through them one by one.

When you have

(2,-3) x= 2 and y = -3 so if we put this into the equation you get
(3x2) -(2x-3) which is 6–6 which is 6+6 which is 12, so this coordinate is CORRECT

(4,0)
X= 4, y =0
(3x4) - (3x0) = 12 so is CORRECT

(5,-1)
X= 5 y = -1
(3x5) - (2x-1) = 15- -2 = 15+2 = 17 so is INCORRECT

(0,-6)
X= 0 y= -6
(3x0) - (2x -6) = 0- -12 = 0 + 12 = 12 so is CORRECT

(2,3)
X = 2, y=3
(3x2)- 2x3 = 6-6 = 0 so is INCORRECT

Hope this helps, let me know if you have any questions

Chloe went on vacation with her family and they decided to swim with the dolphins there's a flat fee of $75 for the family to rent wet suits additionally a cost an extra $189.99 per person to swim with the dolphins the families total cost was $1024.99 how many family members went swimming with the dolphins

Answers

Answer:

5 family members went swimming with the dolphins.

Step-by-step explanation:

From the information given, you can say that the total cost for the family to swim with dolphins is equal to the flat fee for the family to rent wet suits plus the extra cost per person for the number of family members:

1024.99=75+189.99x, where x is the number of family members

Now, you can solve for x:

1024.99-75=189.99x

949.99=189.99x

x=949.99/189.99

x=5

According to this, the answer is that 5 family members went swimming with the dolphins.
