The solution is x = -61/8 and y = -1/2.

Step-by-step explanation:

The given equations are -4x + 3y = 29 and 2y + 5 = 4

Step 1 : There is no x term in the second equation.

Step 2 : Solve for y, 2y = 4 -5

y = -1/2

Step 3 : Substitute y = -1/2 in first equation and solve for x.

Step 4 : -4x + 3(-1/2) = 29

-4x -(3/2) = 29

-8x -3 = 29 $\times$ 2

-8x = 58 + 3

x = -61/8

Can you please help me solve thanks step by step

shusha [124]

Answer:

40 degrees

Step-by-step explanation:

We know the entire angle of ABD is 70 and CBD and ABC are in it.

Since we know one of them (CBD) is 30, we can subtract 30 from 70 to find ABC. This is because the angle of ABC and CBD equal ABD.

30 + x = 70

-30 from both sides

x = 40

Simplify the following expression (30/45g+20)-(8/9g+7)

amid [387]

The answer is: $13-\frac{2}{9}g$

The explanation is shown below:

1- You have the following expression given in the exercise:

$(\frac{30}{45}g+20)-(\frac{8}{9}g+7)$

2- When you multiply signs, you obtain:

$\frac{30}{45}g+20-\frac{8}{9}g-7$

3. Now, you must add like terms, as following:

$-\frac{2}{9}g+13$

4. Therefore, you have that the expression simplified is:

$13-\frac{2}{9}g$
