Answer:

18 or 9 13/34

Step-by-step explanation:

6 - 1 * 16 + 21 ÷ 3 4 ?

Remember the order of operations

6 - 1 * 16 + 21 ÷ 3/4

6 - 16 + 21 * 4/3

6 - 16 + 28

-10 + 28

18

or

6 - 1 * 16 + 21 ÷ 3 4 ?

remember the order of operations

6 - 16 + 21 ÷ 34

6 - 16 + 21/34

-10 + 21/34

9 13/34

Solve for x show work -4 1/4x-7 6/8x=-190

mojhsa [17]

Answer:

x = 15 5/6

Step-by-step explanation:

-4 1/4x-7 6/8x=-190

get a common denominator 8

-4 1/4*2/2 x - 7 6/8 x = -190

-4 2/8 x - 7 6/8 x = -190

combine like terms

-11 8/8 x = -190

-12x = -190

divide by -12

-12x/-12 = -190/-12

x = 190/12

divide top and bottom by 2

x = 95/6

change to an improper fraction

6 goes into 95 15 times with 5 left over

x = 15 5/6

If anybody now this pls help my homework due TOMORROW

Nezavi [6.7K]

Answer:

<u><em>Part A:</em></u> D. $y = (x + 1)(x+3)\\$

<u><em>Part B:</em></u> C. $3x(x-3) = 0\\$

Step-by-step explanation:

For part A) we just have to plug in 0 for x and solve for y until we find the equation that says 3 is the value for y when x is 0. For purposes of speeding up the process the correct answer is D. I will show how to check for it now.

The equation: $y = (x + 1)(x+3)$

Now plug in 0 for x.

$y = (0 + 1)(0+3)\\$

Now solve.

y = (1)(3)

y = 3

This proves that this is the correct answer.

For part B) we just have to plug in the give values for x separately and check for each value of x that it equals 0. For the purpose of speeding up the process the correct answer is C. I will show how to check for it now.

The equation: $3x(x-3) = 0$

Now plug in x for 0 and solve:

$3* 0 (0-3) = 0\\$

$0(-3) = 0\\$

$0 =0\\$

This equation is true, now we check for the other value of x, 3.

$3*3(3-3) = 0\\$

$9(0) = 0\\$

$0 =0\\$

This is also true so that means this is the correct answer.

Can someone please help? Thank you :)

The value of x is 8.

Solution:

Given $\triangle V D G \sim \triangle V N Q$ .

DG = 60, NQ = 48, DN = 15, NV = x + 4

<u>To find the value of x:</u>

<em>Property of similar triangle:</em>

If two triangles are similar then the corresponding angles are congruent and the corresponding sides are in proportion.

$$\Rightarrow\frac{DG}{NQ} =\frac{DN}{NV}$

$$\Rightarrow\frac{60}{48} =\frac{15}{x+4}$

Do cross multiplication.

$$\Rightarrow60(x+4)=15\times48$

$$\Rightarrow60x+240=720$

Subtract 240 from both side of the equation.

$$\Rightarrow60x+240-240=720-240$

$$\Rightarrow60x=480$

Divide by 60 on both sides of the equation.

$$\Rightarrow\frac{60x}{60} =\frac{480}{60}$

$$\Rightarrow x=8$

Hence the value of x is 8.
