Answer:

C and A are your answers

x = 4.4

Step-by-step explanation:

2.2x - 10.5 = -1.7

First, we use the addition property of equality and add 10.5 to both sides of the equation:

2.2x = 8.8

Then we use the division property of equality and divide both sides by 2.2

x = 4.4

Answer:

2/10. There are 10 people in total and only 2 of them are ordering turkey subs. Just add the fractions

Step-by-step explanation:

Answer:

d) x=6

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

622=37x+400

Step 2: Flip the equation.

37x+400=622

Step 3: Subtract 400 from both sides.

37x+400−400=622−400

37x=222

Step 4: Divide both sides by 37.

37x/37=222/37

x=6

Answer:

1. A

2. D (Maybe not sure)

3.C

Step-by-step explanation:

Answer:

Number 1 is 128.52 Number 2 is 18.56

Step-by-step explanation:

Find the area of the partial circle

Diameter is 6 so the radius is 3

A=[tex]\pi r^{2}[/tex]

A=2*3.14*[tex]3^{2}[/tex]                                  [tex]3^{2}[/tex]=9

A= *3.14*9

A=28.26

Now find the area of the rectangle

A=lw

A=6*12

A= 72

Add both of the answers

Answer is 128.52

Number 1

For triangle

A=1/2bh

A=1/2*3*4

A=1/2*12

A=6

Find the area of the circle

Diameter is twice a radius so the radius would be 2

A=[tex]\pi r^{2}[/tex]

A=3.14*[tex]2^{2}[/tex]

A=3.14*4

A=12.56 Add it to 6

A=18.56

Answer: No

Step-by-step explanation:

1 1/3 = 1 2/6

1 2/6 + 2 / 5/6 = 3 7/6

3 7/6 = 4 1/6

4 1/6 - 4 = 1/6

Answer:

13

Step-by-step explanation:

Divide 118 by 9 to get 13.1111111111 which rounded to a whole number gives you 13.

Answer:

The answers of all four questions are below.

Step-by-step explanation:

(5)4+2x=−2x+44

Step 1: Simplify both sides of the equation.

2x+4=−2x+44

Step 2: Add 2x to both sides.

2x+4+2x=−2x+44+2x

4x+4=44

Step 3: Subtract 4 from both sides.

4x+4−4=44−4

4x=40

Step 4: Divide both sides by 4.

4x/4=40/4

x=10

-----------------------------------------------------------------------------------------------------------------

(6)114−3x=194−11x

Step 1: Simplify both sides of the equation.

114−3x=194−11x

114+−3x=194+−11x

−3x+114=−11x+194

Step 2: Add 11x to both sides.

−3x+114+11x=−11x+194+11x

8x+114=194

Step 3: Subtract 114 from both sides.

8x+114−114=194−114

8x=80

Step 4: Divide both sides by 8.

8x/8 = 80/8

x=10

------------------------------------------------------------------------------------------------------

(7)4x-12=-2x+36

4x-12+12=-2x+36+12

4x=-2x+48

4x+2x=-2x+48+2x

6x=48

6x/6=48/6

x=8

-----------------------------------------------------------------------------------------------------------

(9)-3x+90=117-12x

-3x+90-90=117-12x-90

-3x=-12x+27

-3x+12x=-12x+27+12x

9x=27

9x/9=27/9

x=3

Answer:

27.85 feet

Step-by-step explanation:

There might be a more advanced/simpler way to do this.

Perimeter of the squared end (3 of the 4 sides of the square) = 15 feet. Perimeter of the flat part of the rounded end is also = 5 feet.

So all we need is the arc. And they tell you it's a 1/4 circle. So it's 1/4 the circumference of the circle.

We know that the radius of the circle is 5 feet, because that's part of the square.

Circumference = 2(pi)(r)

C = (2)(3.14)(5)

C = 31.4

Divide that by 1/4 for the perimeter/circumference of that 1/4 circle = 7.85

15 + 5 + 7.85 = 27.85 feet

Answer:

D.

Step-by-step explanation:

This will be D because the beaker already has 0.2 mL of water. If Jovita needs to add more water to the beaker, and then it is 0.8. In D, the diagram shows you 0.2 + x = 0.8, which makes it the right diagram.

Hope that helps!

Answer:

The Answer would be D.

Step-by-step explanation:

Because O.8 is the sum of how much 0.2+x equals to.
