I NEED HELP PLEASE!!!!!! I will make you as brainleyest of watever

Answer:

y=4

Step-by-step explanation:

First, you should simplify this equation. To do that, we need to multiply 3 by 4y and 3 by 7. This will make the equation 12y+21=69. Subtract 21 from both sides to isolate y. This will make the equation 12y=48. You want the y to be by itself so you have to divide 12 by each side to get y=4. Therefore, the answer is y=4.

Hope this helps

That is the answer...

Answer:

[tex]x = 3\pm 5i[/tex]

Step-by-step explanation:

Quadratic formula

[tex]x = \frac{6 \pm \sqrt{36-4(1)(34)}}{2(1)}[/tex]

There are no real solutions since the discriminant is negative.

Simplify this to get x = 3+5i, 3 -5i

Answer:

150 minutes

Step-by-step explanation:

P.S - The exact question is -

Given - This is the pond in a shape of a prism, it is completely full of

             water. Colin uses a pump to empty the pond. The level goes

             down by 20 cm in the first 30 min.

To find - Work put how many minutes Colin has to wait for the pond

               to completely empty.

Proof -

Given that,

Height of prism = 1 m

Also,

Base of the prism is trapezium and

Sides of the trapezium are 0.6 m and 1.4 m

Height of trapezium is 2 m

We know that,

Area of trapezium = [tex]\frac{1}{2}[/tex]× (sum of sides)× height

                             =  [tex]\frac{1}{2}[/tex]× (0.6 + 1.4)× 2

                             =  [tex]\frac{1}{2}[/tex]× (2)× 2

                             =  2 m²

⇒Area of trapezium = 2 m²

Now,

Volume of prism = Area of trapezium × height of prism

                          = 2 m² × 1 m

                          = 2 m³

⇒Volume of prism = 2 m³

Now,

Given that the level goes down by 20 cm in the first 30 min

We know

100 cm = 1 m

⇒1 cm = [tex]\frac{1}{100} m[/tex] = 0.01 m

⇒20 cm = 20×0.01 m = 0.2 m

⇒The level goes down by 0.2 m in the first 30 min.

Also,

we know that height of water = height of prism = 1 m

So, the remaining water left in the pond = 1 m - 0.2 m = 0.8 m

Also,

Volume of Remaining water = Area of trapezium × height

                                           = 2 m² × 0.8 m

                                           = 1.6 m³

⇒Volume of Remaining water = 1.6 m³

Now,

Volume of emptied water = Total Volume - Volume of Remaining water

                                       = 2 m³ - 1.6 m³

                                       = 0.4 m³

⇒Volume of emptied water = 0.4 m³

Now,

0.4 m³ water will be empty in 30 minutes

⇒ 1 m³ water will be empty in [tex]\frac{30}{0.4}[/tex] = 75 minutes

⇒1.6 m³ water will be empty in 1.6 × 75 = 120 minutes

∴ we get

The remaining water is empty in 120 minutes

So,

Total pond is empty in 120 + 30 minutes

⇒Total pond is empty in 150 minutes

Answer:

33

Step-by-step explanation:

The pattern is y = 5x + 8.

So, plugging in 5 for x gives you y = 5(5) + 8 = 33.

Answer:

168

Step-by-step explanation:

5+23/2=14

14x12=168

Answer:

The other person is correct. She didn't correctly distribute 3 to -10. The result would have been 3x - 30 instead of 3x + 30. If you multiply a positive number by a negative number, the answer will be negative. :)

Answer: D

Step-by-step explanation: You need to divide the figure into 2 parts. You need to ignore 13 m And use the other numbers. Figure A is 9x3x4 and Figure B is 7x4x4 because the other 4 is at the bottom. I hope this helps. Good luck!

Answer:

-4

Step-by-step explanation:

ok negative times negative = positive

and factors of 24 are

1,2,3,4,6,8,12,24

4 x 6 are the two consecutive EVEN numbers

so turn it to negative

-4 x -6 = 24

The largest is -4

Answer:

j-10=35

Step-by-step explanation:

10 less than j means j-10 is 35

=> j-10=35

Answer:

f-10=35 thus meaning f=45

Step-by-step explanation:

f - 10 = 35

 +10   +10

    f=45

Answer:

The answer is D) The car travels 53 mph(Miles Per Hours).

212/4 = 53

318/6 = 53

424/8 = 53

530/10 = 53

Step-by-step explanation:

Answer:

C)  rate of change is 53, your car travels 53 miles every 1 hour .

Step-by-step explanation:

Given : Table for time and distance.

To Find : The rate of change is constant in each table. Find the rate of change. Explain what the rate of change means for the situation.

Solution : We have given that Table for time and distance.

rate  of  change= (change in y)/(change in x) .

rate  of  change=(212)/(4) .

rate of change =  53.

rate  of  change= (318)/(6).

rate of change =  53

rate of change =  (424)/(8).

rate of change =  53.

rate of change =  (530)/(10) .

rate of change =  53.

Therefore, C)  rate of change is 53, your car travels 53 miles every 1 hour .

Answer:

<0.4

Step-by-step explanation:

subtract 1 from the number and see which number is greater

Answer: See explanation

Step-by-step explanation:

We are going to solve this by using the Simple interest formula which is:

= Principal × Rate × Time

= 500 × 3% × 8/12

= 500 × 0.03 × 2/3

= 10

Therefore, the interest will be $10 ane the total amount that'll be paid back will be:= $500 + $10 = $510
