which does not represent two equivalent expressions 51 MAFS.6.EE.1.1 Which does not represent two equivalent expressions?

A.) 33=3·3·3
B.) 43=4·3
C.) 64=6·6·6·6
D.) 52=5·5

Answers

Answer 1

Answer: B

Explanation: 4 times 3 is equivalent to 12 and the question was asking for exponents. A has 3 multiplied by itself 3 times so that is correct. C has 6 multiplying itself 4 times so that would be correct. D has 5 Multiplying itself 2 times so that would be correct. The only one that does not represent equivalency would be B.

141x + 50 + 4x = 340
What is x?

Answers

Answer:

x = 2

Step-by-step explanation:

141x + 50 + 4x = 340

=> 145x + 50 = 340

=> 145x = 290

=> x = 2

Hoped this helped.

Simplify both sides of the equation

141x+50+4x=340(141x+4x)+(50)=340(Combine Like Terms)145x+50=340145x+50=340

Subtract 50 from both sides

145x+50−50=340−50145x=290

Divide both sides by 145

[tex] = > \frac{145x}{145} = \frac{290}{145} [/tex]

x=2

Jaylen's beta fish tank holds 4 1/2 gallons of water. It takes him 1 7/8 minutes to fill it. What is the flow rate of the water in gallons per minute? (label your answer gpm) pls dont delete or post links Ty worth 29 points and brainlyiest

Answers

I had this same question! ill tell you what i got.

Answer:

12/5

Step-by-step explanation:

His fish tank is 4 1/2 gallons of water. It takes him 1 7/8 minutes to fill it. So you need to find out how many gallons you can pour in 1 minute. You can eliminate A (5/12) because he is filling more than 1 gallon per minute. You can divide   4.5 (4 1/2) by 1.875 (1 7/8). You get 2.4. Convert it back to a fraction, and you get 2 4/10. Simplify the fraction 2/5. Now convert it to an improper fraction. 12/5.

Answer:

a.) The sum of the weights of the two in insects is 0.0031 grams. (0.0031 grams)

b.) The fly is 0.0013 grams heavier than the gnat. (0.0013 grams)

Step-by-step explanation:

2.2 * 10^-3 = 2.2 * 1/1000 which is 2.2/1000.

9 * 10^-4 = 9 * 1/10000 = 9/10000

To add 9/10000 to 2.2/1000 we have to find the common denominator, which will be 10000.

So we do:

2.2/1000 * 10/10 = 22/10000

9/10000 + 22/10000 = 31/10000 = 0.0031.

The sum of the weights of the two in insects is 0.0031 grams.

To find how much heavier the fly is than the gnat we do:

22/10000 - 9/10000 = 13/10000 = 0.0013

The fly is 0.0013 grams heavier than the gnat.

Figure A is 1 2/3 times larger than B. Now multiply the similar side of B to find x:

x = 18 x 1 2/3

x = 30

Answer: x = 30

Answer: 30

So,

X/18 = 45/27

Then cross multiplication

X= 45×18/ 27

X= 30

Answer = 264m squared.

First the rectangle at the top is 20 x 5 which is 100

To figure out the base of the triangle you would look at the width of the second rectangle and from that you would do 20 - 6 so the base of the triangle is 14

With that you would do 14 x 8 = 112 divided by 2 = 56

The area of the second triangle at the bottom is 108 because 6 x 18 = 108

108 + 56 + 100 = 264m squared (squared because it’s area)

−6(x+7)=−30

Enter your answer in the box.

Answers

Answer:

x = -2

Step-by-step explanation:

-6(x + 7) = -30

distribute the -6

-6 * x = -6x and -6 * 7 = -42

-6x - 42 = -30

add 42 to both sides

-6x = 12

divide both sides by -6

-6x/-6 = x and 12/-6 = -2

we're left with x = -2

Ramiro is 3/10 as tall as the flagpole. The flagpole is 5/9 as tall as the nearby tree. The tree is 32 2/5 feet tall. How tall is Ramiro?

Answers

Answer:

5.4 feet

Step-by-step explanation:

Start with the flagpole. It is 5/9 of 32 2/5.

32 2/5 = 162/5.

5/9 * 162/5 = 162/9.

Ramiro is 3/10 as tall as 162/9.

3/10 * 162/9 = 27/5, or 5.4 feet tall

His height is 5.4 f

(-6,-3) and (-1,x)=13 find the value of A

Answers

Distance between two point can be calculated by the equation:

D=sqrt((x2-x1)^2+(y2-y1)^2)
Then,
13=sqrt((-1-(-6))^2+(x-(-3))^2)
We can square both sides to get rid of the square root,
169=(-5)^2+(x-(-3))^2
169-25=(x-(-3))^2
144 =(x-(-3))^2
By taking the square root in both sides, then
12=x+3
In this case,
X=12-3=9
(-6-3) = -9, (-1,x)=13 : x=-13
