3/10 x 5 in a fraction

Answer:

x=-8.5

Step-by-step explanation:

Combine like terms:

9+8=-4x+2x

Solve:

17=-2x

Divide:

17/-2=x

-8.5=x

Answer:

your answer is x=-8.5

Step-by-step explanation:

Answer: x = 9

Angle B = 40

Step-by-step explanation:

5x-5 = 3x+13 Those angles are the same, they are corresponding angles

5x = 3x + 18 Solve the equation

2x = 18

x = 9

3(9)+13 Solve it

Angle B = 40

Answer: The total surface area is 633.9

Step-by-step explanation:

12.25 times 15.75, then divide by 2 = 96.46875 (this is the area of the triangle

Then times 4 = 385.875 (Because there are four triangles

15.75 times 15.75 = 248.0625 (The area of the square)

The sum is 633.9375

Rounded = 633.9

Answer:

C = 2 pi r, so diameter is 40!

Step-by-step explanation

125.6 = 2 pi r

125.6 divided by 2 is 62.8.

Now its, 62.8 = pi times r

62.8/3.14 = 20.

r = 20

but this is the radius so the diameter is 2 times for than the radius. 20 x 2 = 40

Step-by-step explanation:

180 minus 34 degrees gives 146° not that sure

Answer:

Step-by-step explanation:
First, you would want to subtract the 3 on the left side to the right side to get the 1/5x to be alone.
1/5x>6
Next, we need to solve for x, by multiplying 5 to cancel out the 1/5.
(5)1/5x>6(5)
That leaves us with x>30
treat the inequality sign as an equal sign, that should help

Answer:

132

Step-by-step explanation:

No way you can find the whole area with one solution. So we have to go by each shape.

Let's start with the triangle on top, only one part of it. We know that half of the base is 3. We could go long and hard and use the pythagorean theorem and then repeat that 8 times. Instead, you can imagine moving the 2 triangles into a rectangle. Now you have a rectangle that is 3x4 inches. Repeat 4 times for each of the triangles. Then just the square which is 6x6. Add them and bam!

Answer:

1 3 4 5 6 7 8 10

Step-by-step explanation:

the numbers 7,8,9,0 represent 8th graders and the groups 1 3 4 5 6 7 8 10 all contain at least one of the numbers while the others groups dont meaning they are no 8th graders in groups 2 or 9

Answer: x=15

Step-by-step explanation:

x/3+1= 6

Step 1: Subtract 1 from both sides (always do inverse operations with the number, not the x term(s))

x/3 + 1-1 = 6-1

x/3= 5

Step 2: Now we need to isolate x (get it on its own). To do this, we must move the 3 to the other side, which we will do by multiplying the 3 and the 5 (as since the 3 was used for divisision, its inverse operation is multiplication).

x/3 = 5

x = 5x3

x= 15

Step 3: Check by using PITA, or "Plugging In the Answers"

We came to the conclusion that x=15. Now, we can "plug in", or substitute the x in the equation for 15:

x/3 + 1= 6

15/3 + 1= 6

5+ 1= 6

6=6

Correct ✔️

Answer:

X = 24

Step-by-step explanation:

3 + 1 = 4

X/4 = 6

Multiply both sides by 4

X = 24

Answer:

Surface area = 136 cm²    Volume = 80cm³

Step-by-step explanation:

Surface Area = face 1 + face 2 + face 3 + face 4+ face 5 + face 6

SA = 2(4) + 2(4) + 2(10) + 2(10) + 4(10) + 4(10)

SA = 8 + 8 + 20 + 20 + 40 + 40

SA = 16 + 40 + 80

SA = 136

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

Volume = l*w*h

Volume = 4*2*10

Volume = 8*10

Volume = 80

Hey there!

PROBLEM #1. 4 * 2,160

4 * 2,160
= 2,160 * 4

= 2,160 + 2,160 + 2,160 + 2,160

= 4,320 + 4,320

= 8,640
Therefore, the answer should be: 8,640

Problem #2. 4 * 2,610
4 * 2,610
= 2,610 * 4

= 2,610 + 2,610 + 2,610 + 2,610

= 5,220 + 5,220

= 10,440

Therefore, the answer should be:

10,440

Answer: it's A

Step-by-step explanation:

since the cost for hiring a plumber for three hours costs $120 so in graph A the graph has more likely stopped at $120 on the y axis which can be said as the cost axis too. I'm pretty sure the answer is A!

Answer:

5) Y = 144

Step-by-step explanation:

[tex]\frac{Y}{1.8} = 80[/tex]

Bring 1.8 from the numerator to the denominator and change the sign from divide to multiply. Also, the 1.8 switches sides so the equation looks like:

Y = 80*1.8

Y = 144

Hence, Y is equal to 144.
