help me pls i dont get this

Answer: X=  -4  

Step-by-step explanation:

4x+28= -6x-12 (28-28), (12-28)

4x= -6x - 40

(add 6x to both sides)

4x+ 6x= -6x-40 + 6x

(combine 4x+6x)

10x = -40

(divide 10)

10x/10x

-40/10x

X= -4

Answer:

1

Step-by-step explanation:

To solve for x, we can isolate x on one side of the equation by undoing the operation of the expression inside the parentheses. To do this, we need to subtract 2 from both sides of the equation:

9 = 3(x + 2)

9 = 3x + 6

3 = 3x

Finally, we divide both sides by 3 to obtain:

x = 1

So, the value of x is 1.

Step-by-step explanation:

if we symbolize girls as g boys will be g+6;

then if boy/girl=7/4

the[tex]\frac{g+6}{g} =\frac{7}{4} \\4*(g+6)=7g\\4g+24=7g\\3g=24\\g=8\\boys=g+6=14[/tex]n

Answer:

40.63% to the nearest whole percent is 41

Step-by-step explanation:

(45 - 32) / 32) * 100 = 40.63 %

To round 40.63 to the nearest whole number consider the tenths’ value of 40.63, which is 6 and equal to or more than 5. Therefore, we have to round up: the whole number part of 40.63, 40, increases by 1 to 41, and the decimal point and all digits (.63) are removed...

40.63 rounded to the nearest whole number = 41

Answer:

C. $36.36

Step-by-step explanation:

You need to find the surface area of the box. Then, calculate how much it will cost.

SA = 2(wl + hl + hw)

SA = 2([11*8] + [6*8] + [6*11])

SA = 2(88 + 48 + 66)

SA = 2(202)

SA = 404 inches

9 cents per inch

0.09*404 = 36.36

Answer: Pretty positive it would be 2/12 because the bottom numbers are the same so nothing happens to them. 5-3 is 2 so 2/12

Answer:

2/3

Step-by-step explanation:

5/9 ÷ 5/6 = 5/9 x 6/5 = 30/45 = 6/9 = 2/3

So, the answer is 2/3

Answer:

Answer is in the attached photo.

Step-by-step explanation:

The solution is in the attached photo, do take note to solve this question, angles properties must be used.

Answer:

x=48°

Step-by-step explanation:

We can see the line at the top. 52°+y+59°=180° because these angles are supplementary angles. We can solve this problem:

52°+y+59°=180°

y=180-52-59

y=180-111

y=80-11

y=69°

because the angles in a triangle add up to 180°, y+63°+x=180°, or

69°+63°+x=180°

We can solve it from here:

69+63+x=180

120+12+x=180

132+x=180

x=180-132

x=80-32

x=48°

Answer:

First question's answer: 28y

Second question's answer: c + 12

Step-by-step explanation:

first question explanation:

7(4y) =28y

7 times 4 is 28, simply attach the y on.

Second question explanation

(0 + c) + 12 = c + 12

0 + c simplifies to just c

c + 12 cannot be simplified even more

hope this helps :)

Answer:

1. 28y

2.  c + 12

Answer:

Change in temperature is +8° C

Step-by-step explanation:

Change in temperature = Final temperature - Initial temperature:

                                =ΔT = [tex]F_{T} - I_{T}[/tex]

                                        = (- 2° C)- (- 10° C)

                                        = [tex]- 2 + 10[/tex]

∴ Change in temperature  = + 8° C

Answer:

258 ft

Step-by-step explanation:

seperate the polygon into two boxes that way u have one big box that is 21 ft in width and 8 ft in height. Then multiply 21*8 to find the area of the box which is 168.

for the other box you can find the height by subtracting 18 ft and 8 ft from the first box which gives a height of 10 ft. To find the wisth you have to subtract 21-12 which is 9. Now you can multiply 10*9=90

Add the two boxes together:

90+168=258

Answer:

2/12 of a mile

Step-by-step explanation:

Answer: A: Yes

B: 12 Customers

Step-by-step explanation:

Part A: Yes since each time it can go up by 1 for customers and 48 for towers each time

Part B: 1 customer (thousands) is equal to 48 towers

so if there are 576 towers let's divide: 576/48 = 12

There will be 12 customers (thousands) for 575 towers

Answer:

21

Step-by-step explanation:

The area of a triangle is (1/2) * base * height. In this case, the base is the distance between (-5, -2) and (1, -2), meaning it's 6 units. The height is the distance from (-3, 5) to the line y = -2, so the height is 7 units. So, the area is (1/2) * 6 * 7 = 21 square units

Answer:

[tex](7a \cdot 5b) \div 6c \cdot 2d[/tex]

Step-by-step explanation:

If there is both multiplication and division in an expression and no parentheses, you start solving from left to right. Since in the expression [tex]7a \cdot 5b \div 6c \cdot 2d[/tex] you would start by solving [tex]7a \cdot 5b[/tex], (because it's at the leftmost part of the expression) it won't matter whether you put parentheses around [tex]7a \cdot 5b[/tex] or not. Therefore, the expression [tex](7a \cdot 5b) \div 6c \cdot 2d[/tex] is equivalent to [tex]7a \cdot 6b \div 6c \cdot 2d[/tex].

Answer: 4-3a

Step-by-step explanation:

Answer:

Step-by-step explanation:

Velocity is change in displacement over change in time.

v = d/t

In this problem, d = 1.6 km and t = 20 minutes

To find the velocity, divide 1.6 by 20, and you get 0.08 km/min.

You could also convert this to km/hour by dividing 1.6 km by 1/3 hours, and the velocity would be 4.8 km/hour.

[tex]\frac{5}{16}[/tex] + 1 [tex]\frac{8}{16}[/tex]

Answer: 2/15 and 9/10

Step-by-step explanation:

Set up cross-multiplication.

If Michelle reads 1/3 book in 2 1/2 hours, she reads X in 1 hour.

                      1/3          2 1/2

                          x           1

1/3 = 2 1/2 x

divide by 2 1/2

1/3 divided by 2 1/2 = convert 2 and a half to 5/2

1/3 divided by 5/2 - keep, change, flip. (your teacher should have covered a method like that)

1/3 times 2/5 is 2/15.

For question 2, lets do the same thing.

3/5 times 2/3 equals x times 1

3/5 times 1 is 3/5

2/3 times x is 2/3x

(this looks better on paper)

3/5=2/3x

divide by 2/3

Answer: B

The poster is formed by a triangle and a rectangle, with their formula for the area being [tex]\frac{1}{2}[/tex] x base x height and base x height respectively.

Therefore, the area is  [tex]\frac{1}{2}[/tex] x 27cm x 12cm + 20cm x 15cm, answer being 462cm2 (b) .
