Answer: The combined amount of kids and adult meals sold = 36

Step-by-step explanation:

Let the number of kids meals sold = 5x and the number of adult meals = 4x

Since total kids meals sold = 20

Then, 5x= 20

⇒ x =4

Adult meals = 4(4) = 16

Combined meals sold  =  kids meals + Adult meals

= 20+ 16

= 36

Hence, the combined amount of kids and adult meals sold = 36

Step-by-step explanation:

A. 3x+4/2 = 9.5

3x + 4/2 = 9.5........criss cross

3x+4= 9.5×2

3x = 19-4

3x = 15

x=5 ..........divide both sides by 3

B. 7+ 2x/3= 5.......criss cross

7+2x = 5 × 3

7 + 2x = 15

2x = 15-7

2x = 8......divide both sides by 2

x = 4

Answer:

Area = 144   Perimeter = 48

Step-by-step explanation:

if the garden is square and the length is 12 all you do is 12 * 12 for the area and 12+12+12+12 for the perimeter.

Answer: it is A

Step-by-step explanation:

it is 6xy^2

Answer:a

Step-by-step explanation:

Answer:

1/2

Step-by-step explanation:

y = mx + b

the "m" is the slope

and the b is the y-intercept

as you can see from the equation y = 1/2x + 3

the 1/2 substituted the m which is the slope

so the slope of the line is 1.2

Answer:

wE nEeD cRoNa tO DiE

Step-by-step explanation:

divide cost by quantity. The lowest rate is the best buy:

26/8 = 3.25 each

30/5 = 6.00 each

15/4 = 3.75 each

39/12 = 3.25 each

45/10 = 4.50 each

The 8 for 26 and the 12 for 39 are both the same price each and are the better buys.

Answer:

x = 14

Step-by-step explanation:

First, use the distributive property:

-7x + 14 = -84

-7x = -98

x = 14

Answer:

my answer got deleted for no reason so ill add it again with my way of solving it with steps this time.

x=14

Step-by-step explanation:

divide both sides by -7

[tex]\frac{-7(x-2)}{-7} =\frac{-84}{-7}[/tex]

simplify

[tex]x-2=12[/tex]

add two to both sides

[tex]x-2=12[/tex]

    [tex]+2[/tex]   [tex]+2[/tex]

simplify

[tex]x=14[/tex]

hope having another method helps :)

Answer:

this is

12-y=5

12-y =5

y=5- 12

then y=7

could you see this this correct

Answer:

7

Step-by-step explanation:

do 12-5 which is 7

that is the answer

you need to find which number needs to be subtracted from 12 to make 5!

Answer:

180°

Step-by-step explanation:

The sum of the 3 interior angles of a triangle = 180°

Answer:

m<1 = 54

m<3 = 54

m<4 = 126

Step-by-step explanation:

<1: <2 and <1 are supplementary angles.

<3: <2 and <3 are supplementary angles. <1 and <3 are vertical angles.

<4: <2 and <4 are vertical angles.

Supplementary angles equal to 180 degrees.

Vertical angles are equivalent.

Let's solve for <1.

<2 + <1 = 180 --> Due to supplementary angles

126 + <1 = 180 --> Substitution

126 + <1 - 126 = 180 - 126 --> Subtracted 126 on both sides

<1 = 54 --> Simplified

Let's solve for <3.

<3 = <1 --> Due to vertical angles

<3 = 54 --> Substitution

Let's solve for <4.

<4 = <2 --> Due to vertical angles

<4 = 126 --> Substitution

Therefore, m<1 = 54, m<3 = 54, and m<4 = 126

Hope this helped! <3

Answer:

1 is 54 degrees

3 is also 54 degrees

4 is 126 degrees

Answer:

Solving the expression: [tex]\frac{3}{4}g=-12[/tex] we get: [tex]\mathbf{g=-16}[/tex]

Step-by-step explanation:

We need to solve the expression: [tex]\frac{3}{4}g=-12[/tex] and find the value of g

Solving:

[tex]\frac{3}{4}g=-12[/tex]

Multiply both sides of the equation by [tex]\frac{4}{3}[/tex] because we need to find value of g.

[tex]\frac{3}{4}g\times \frac{4}{3} =-12\times \frac{4}{3}\\g=-4\times 4\\g=-16[/tex]

So, we get g = -16

Solving the expression: [tex]\frac{3}{4}g=-12[/tex] we get: [tex]\mathbf{g=-16}[/tex]

Answer:

The length is 6.875 (6.9) ft, the width is 5 ft, and the area is 34.375 (34.5) [tex]ft^{2}[/tex]

Step-by-step explanation:

If the scale is 4 in to 5 ft, we can simply divide 5 by 4 to find out the scale by which we would multiply one inch. The reason it is 5/4 and not 4/5 is because 5 ft > 4 in. 5/4 = 1.25. 1.25 * 5.5 = 6.875. When rounded to the nearest tenth, it is 6.9. Using the same measurement NOT rounded, it is 34.375, but using the rounded value the answer is 34.5 sqft.

Hope I helped! Also, if this is wrong someone please correct me.

Answer:

angle a = 53.13°

angle b = 36.87°

angle c = 90°

Step-by-step explanation:

The following is one way to perform the calculation. It may not be the best way.

Calculates ∠A, ∠B, ∠C based on given a, b and c.

∠A = arccos(  b2 + c2 - a2 2bc )

= 0.9273 rad = 53.13° = 53.13°

∠B = arccos(a2 + c2 - b2 2ac )

= 0.6435 rad = 36.87° = 36.87°

∠C = arccos(a2 + b2 - c2 2ab )

= 1.5708 rad = π/2 = 90°

Answer:

They will each get ;

(x-t)/2 - 60

Step-by-step explanation:

Here, we want to know the amount of money that Colin and his wife gets

we start by subtracting the necessary terms

Mathematically, that would be;

x-t-120

So what each of them get will be;

(x-t-120)/2

= (x-t)/2 - 60

Answer:

6

Step-by-step explanation:

EQUATIONS:

24x + 32y = 264

x + y = 9

x is shirts, y is pants

SOLVING by substitution:

x = 9 - y

24(9 - y) + 32y = 264

216 - 24y + 32y = 264

8y = 48

y = 6

x + 6 = 9

x = 3
