78 = -2(m + 3) + m;

78 = -2m - 6 + m;

78 = -m - 6;

m = -6 - 78;

m = -84

78 = -2m - 6 + m;

78 = -m - 6;

m = -6 - 78;

m = -84

x - 9 = -6x + 5;

x + 6x = 5 + 9;

7x = 14;

x = 14/7;

x = 2

x + 6x = 5 + 9;

7x = 14;

x = 14/7;

0.6(y + 3) = 4.8 User: 6=2(x+8)-5x **Weegy:** -5x+6=6 X is 1 **User:** –6 + 3x = –9 **Weegy:** The answer for 3x^9/3x^3 is x^6. **User:** 4/5x + 5 **Weegy:** 5x = 3
Divide both sides by 5.
Your answer is x = 3/5 **User:** Solve the equation. –6 + 3x = –9 **Weegy:** 3x = 45 x = 15 (divide both sides by 3, 45/3 = 15) **User:** - 1/3m – 7 = 5 **Weegy:** - 1/3m - 7= 5 ===> - 1/3m = 5 + 7 = 12 ===> m = 12*(-3) = -36 **User:** You drop a rock off a bridge. The rock’s height, h (in feet above the water), after t seconds is modeled by h = -16t2 + 541. What is the height of the rock after 2 seconds? **Weegy:** There are 3 main processes that "build" rock.
1. Igneous rock is formed from molten lava as it cools at the surface of earth or from magma (also molten material) which cools and solidifies at some subsurface depth.
2. [ [ Metamorphic rock is formed when rocks are exposed to high temperature and/or pressue. The T and P changes cause new minerals to form in the rock.
3. Sedimentary rocks form in two ways both as a results of deposition. Clastic rocks (e.g. sandstone) are the result of deposition of eroded material from other rocks, generally the deposition of clastics occur at relatively low energy environments which allow for deposition as opposed to erosion and transport. Carbonates and evapourites are deposited in-situ (are not gernally transported from other locations), where carbonates are built out of the shells of marine animals, while evapourites are deposited due to evapouration of mineral rich water. ] ] **User:** Solve the equation.
-6p - 21 = 3p - 12 **User:** x/5 + 9 = 4
A. 65
B. –25
C. 5
D. 20 **User:** x/5 + 9 = 4

0.6(y + 3) = 4.8

y + 3 = 4.8/0.6 = 8

y = 8 - 3 = 5

y + 3 = 4.8/0.6 = 8

y = 8 - 3 = 5

6=2(x+8)-5x

6 = 2x + 16 - 5x

3x = 16 - 6 = 10

x = 10/3

6 = 2x + 16 - 5x

3x = 16 - 6 = 10

x = 10/3

–6 + 3x = –9

3x = -9 + 6 = - 3

x = -3/3 = -1

3x = -9 + 6 = - 3

x = -3/3 = -1
