4x+2+2x+10 = 90

6x + 12 = 90

x = 90-12/6

= x = 13

MARK ME AS BRAINLIEST

Answer:

x= 13

Step-by-step explanation:

4x+2+2x+10=90

collect like terms

4x+2x+10+2=90

6x+12=90

collect like terms again

move 12 to the other side then the sign will change to minus -

6x=90-12

6x=78

divide both sides by 6

6x/6=78/6

x=13

Answer:

-16> k

so the answer is C

Step-by-step explanation:

Answer:

k > -16

Step-by-step explanation:

-5 > k + 11

→ Add -5 to both sides

0 > k + 16

→ Minus k from both sides

- k > 16

→ Multiply both sides by -1

k > -16

Answer:

SA = 742

Step-by-step explanation:

H*L + H*W + L*W = SA

(8 x 6) x 2= 96

(22 x 6) x 2 = 264

(8 x 22) x 2 = 352

96 + 264 + 352 = 742

Answer:

712 cm^2

Step-by-step explanation:

Surface area

Base and Top ..........   2 (8*6) = 96  (cm*2)

2 sides ..........               2 (22*6) = 264  (cm^2)

Front and Back .........  2 (8*22) = 352  (cm^2

Total 96+264+352 = 712 cm^2

Answer: it is 0

Step-by-step explanation:

[5.5+(-2.3)] + (-5.5+2.3)

We can multiple (-5.5+2.3) by -1 so that it equals the first expression

[5.5+(-2.3)] + (-1)[5.5+(-2.3)]

Then, we change the + to -

[5.5+(-2.3)] - [5.5+(-2.3)]

since we are subtracting the same value, the answer is 0.

Answer:

1.2 x 10 to the third power

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the  

10  . The sign of the exponent will depend on the direction you are moving the decimal.

So if theres 45 students in total, thats 100% of students, nine of those would be 20%

Answer:

[tex]\frac{4}{13}[/tex]

Step-by-step explanation:

To calculate how many more questions Meta solved then Aliya you have to subtract. So you write the equation:

[tex]\frac{7}{13} - \frac{3}{13} = \frac{x}{y}[/tex]

Then, you move the 13 in place of the y.

Next, you subtract,

7 - 3 = 4. So, 4 = x

[tex]\frac{4}{13}[/tex] is your answer

Answer: An example can be Romeo and Juliet:

Love is naturally the play's dominant and most important theme.

Step-by-step explanation:

Answer:

4x + 2(x – 3) = 4x + 2x – 11

4x + 2x - 6 = 4x + 2x - 11

6x - 6 = 6x - 11

-6 = -11

There is no solution because -6 does NOT equal -11

Answer:

0 solution

Step-by-step explanation:

4x + 2(x – 3) = 4x + 2x – 11

Solve the parentheses:

4x + 2x - 5 = 4x + 2x - 11

Subtract 2x from both sides:

4x - 5 = 4x - 11

From what you can already see that those two expressions does not equal to each other. Let’s continue solving to confirm:

(Subtract 4x on both sides)

-5 = -11

There are 0 solutions

Answer:

55 cm^2

Step-by-step explanation:

Find the area of the large rectangle

A = l*w = 9*7 = 63 cm^2

Then find the area of the unshaded rectangle

A = l*w = 4*2 =8cm^2

Subtract the unshaded area from the large rectangle

63 - 8 =55 cm^2

The shaded area is 55 cm^2

Answer: 55

Step-by-step explanation:

4 x 2 = 8

9 x 7 = 63

63 - 8 = 55

Answer: (2,3)

Step-by-step explanation:

solve by setting both equations equal to each other

1/2x+2=x+1 and then solve for x to get x=2

then plug x back into the equation to get y=3

If 94% haven't arrived yet then the 198 people is 6% of the total.

To find the total people divide the number of people who have arrived by the percentage.

Total people = 198/6% = 198/0.06 = 3300

Total people = 3,300

Answer:

I think musiclover10045 is correct and the answer is 3300

Step-by-step explanation:

They had divided 198/0.06 to get 3300. I agree with this equation and the end product.

Answer:

3 hours and 5 minutes

Step-by-step explanation:

d/st

s=65. d=200

200/65=3°4°36.92

MAKE SURE TO USE DEGREE BUTTON ON CALCULATOR

therefore, 3 hours and 5 minutes

It take 3hours to travel 200miles at the speed of 65 miles per hour.

Speed is the time rate at which an object is moving along a path.

[tex]speed = \frac{distance}{time}[/tex]

According to the question

We have

speed = 65 miles per hour

distance = 200miles

Therefore,

The time taken by them to travel 200 miles at speed 65 miles per hour is calculated as:

[tex]time=\frac{200}{65}[/tex]

[tex]time=3.07hr[/tex]
