Multi-step equation: 4x+6+3=17

Mathematics
1 answer:
Tcecarenko [31]3 years ago
5 0
4x+6+3=17
4x+9(add the 6 and 3)=17
4x=8(subtract 9 from each side 4x+9-9=17-9)
x=2(divide each side by 4, 4x/4=8/4)
2 is the final answer. 

You can check your work...
4(2)+6+3=17
8+6+3=17
14+3=17
17=17
So this is correct!!! Hope this helps you.

Solve −2x − 15 = 6x + 9.
Sindrei [870]

Answer: x=-3

Step-by-step explanation:

Given the equation:

-2x - 15 = 6x + 9

You must solve for "x" to find its value.

You can follow these steps:

- Add 2x to both sides of the equation:

-2x - 15+2x= 6x + 9+2x

- 15 = 8x +9

- Subtract 9 from both sides of the equation:

- 15-9 = 8x +9-9

-24 = 8x

- Divide both sides of the equation by 8. Then you get:

\frac{-24}{8}=\frac{8x}{8}\\\\x=-3

I honestly need help on this...I tried to work it out but I just don’t know where to start...
Ilia_Sergeevich [38]

Answer:

Step-by-step explanation:

1) The sum of angles on a straight line is 180 degrees. Therefore

75 + a + 70 = 180

145 + a = 180

a = 180 - 145 = 35 degrees

2) Sum of the angles in a triangle is 180 degrees. Therefore,

a + b + 95 = 180

35 + b + 95 = 180

130 + b = 180

b = 180 - 130 = 50 degrees

3) c + 95 = 180 degrees (sum of angles on a straight line).

c = 180 - 95 = 85 degrees

4) 70 + c + d = 180 degrees

70 + 85 + d = 180

155 + d = 180

d = 180 - 155 = 25 degrees

5) e = 75 degrees

6) f + e + 75 = 180 degrees

f + 75 + 75 = 180

f + 150 = 180

f = 180 - 150 = 30 degrees

The sign shows distances from a rest stop to the exits for different towns along a straight section of highway. The state depart
torisob [31]
Refer to the diagram shown below.

The exit for Freestone is built midway between Roseville and Edgewood,
therefore the distance from O to the new exit is
(1/2)*(33+55) = 44 mi.

Let x =  distance from Midtown to the new exit.
Because the distance from O to the new exit is equal to (x + 17), therefore
x + 17 = 44
x = 44 - 17 = 27 mi.

Answer:
When the new exit is built, the distance from the exit for Midtown to the exit for Freestone will be 27 miles.
