50 percent of blank is 30

Answer:

(-60/11,111/11)

Step-by-step explanation:

Solving simultaneously, 4x - 3y=6   -3(6x + y=42)   then it becomes, 4x - 3y=6

-18x - 3y= 126 subtracting the two equations,   22x= -120, x= -60/11 and y = 111/11

.

Answer:

(-0.5, 1)

Step-by-step explanation:

4x - y = -3    ----------------------(I)

-6x + 3y = 6 -------------------(II)

Multiply equation (I) by 3 and then add. So, y will be eliminated and you can find the value of x.

(I) * 3         12x - 3y = -9

(II)             -6x + 3y = 6          {Now, add}

                6x          = -3

                          x = -3/6

                          x = - 0.5

Plug in x = -0.5 in equation(I)

4*(-0.5) - y = -3

- 2   - y = -3

     -y   = - 3 + 2

    -y   =  -1

     y = 1

Answer:

It would be 11/3

Step-by-step explanation:

Answer:

I will first divide the shape into two rectangles. first rectangle area would be 60x15=900mm^2. next rectangle is 20x30=600mm^2. 900+600=1500mm^2. the area is 1500mm^2, which is answer D

Answer:

2-1/2 inches long

Step-by-step explanation:

Convert 3-3/4 to an improper fraction by multiplying the whole number by the denominator and adding it to the numerator. Then multiply by 2/3.

15/4 × 2/3

Cross-multiply and divide (simplify)

30/12

5/2

2-1/2

Answer:

D. 12, 15, 25

Step-by-step explanation:

The triangle leg rule states that the smaller two lengths must add up to be greater than the largest length.

This means that the first two values must add up to be greater than the final value.

12 + 15 = 27

27 > 25

So, your answer is D

Answer:

Step-by-step explanation:

[3x-2]÷4=2x-8

3x-2 = 4·(2x-8)

3x-2 = 8x-32

-2 = 5x-32

30 = 5x

x = 6

Answer:

(3x-2)/4= 2x-8  x=6

Step-by-step explanation:

(3x-2)/4 times 4= 2x-8

Multiply both sides by 4

3x-2/4 times 4= 2x  times 4-8 time 4

Simplify

3x= 8x = 8x-30-8x

Subtract 8x from both sides

3x-8x=8x-30-8x

Simplify

-5x=-30

Divide both sides by -5

-5x/-5 = -30/-5

Simplify so you get x=6

Answer:

100%-39%=61% which is 0.61

Step-by-step explanation:

Answer:

Step-by-step explanation:

12x<96. divide both sides by 12

x<8

So it would be a leftward arrow with a hollow dot at 8 because 8 is not included because x is ‘less tha’ 8

Answer:

x < 8

see attached image

Step-by-step explanation:

Start by dividing both sides by 12 (which is a positive number, so the inequality symbol stays as it is)

x < 96 / 12

x < 8

then graph it as the left side of the x-axis to the point 8,   NOT including this point (use an empty dot as shown in the attached image)

Answer:

3.8

Step-by-step explanation:

use pythagoras theorem

a^2+b^2=c^2

a^2+5^2=6^2

a^2+25=36

a^2=36-25

a^2=11

a=3.3

but on the answers provided write 3.8 because its close

Answer:

the answer is the first one [3 -12 15 -21]

Step-by-step explanation:

Because 3 times 1 = 3, 3 times -4 = -12, 3 times 5=15, 3 times 7 = -21

because they are in order to get a negative one of them have to be a negative if they both of them where negative it would be positive.

Answer:

9

Step-by-step explanation:

Answer:

If 500 minutes of talk = 20

and texting = 30

and each additional minute of talk = 0.45

then the bill would be (for C = total cost)

C = 20+30+(0.45 • x)

OR

C = 50 + 0.45x

The y value is 5

y =5

Answer:

choice #6)  2/3

Answer:

I think that's either a Rhombus or a Square.

I think it's more of a Rhombus.

Step-by-step explanation:

If all the sides are equal then its either a Rhombus or a Square. Then look if all the angles are equal and are right angles, Yes? then it's a Square. If only the angles opposite from each other are equal, then it's a Rhombus.

Answer:

3 with the power of 2

Step-by-step explanation:

This is greater because when you multiply 3 by 3 you get 9, and when you multiply 2 x 2 x 2 you get 8

Answer:

105.12 ft²

Step-by-step explanation:

Area of the figure = area of the rectangle + area of half a circle

= L*W + ½(πr²)

Where,

L = 10 ft

W = 8 ft

r = ½ of 8 = 4 ft

π = 3.14

Plug in the values

Area = 10*8 + ½(3.14*4²*)

Area = 80 + 25.12

Area = 105.12 ft²
