Could someone help me with this please? :D

Answer:

m=8

hope this helps

have a good day :)

Step-by-step explanation:

2 + 6m +7=57

9+6m=57 add like terms

6m=48 subtract 9 from each side

m=8 divide by 6 on each side

Answer:

M=8

Step-by-step explanation:

First your going to subtract 2 from 7 and thats 5.

then your going to do:

6m+5=57

Then subtract 5 from 57 and thats 52

and divide 52 from 6 and thats 8.

Answer:

0≤x≤3

Step-by-step explanation:

The domain is just all the possible values of x

we can see that the line goes through the x values 0 through 3

which means that

0≤x≤3

It's ≤ because it's a close circle

Answer:

d

Step-by-step explanation:

all of the angles add up to equal 180 so we setup the equation as 45+3x=180

first you subtract each side by 45

135=3x

then you divide each side by 3 and get that

x=45

Answer:

D, 45°

Step-by-step explanation:

at [tex]x=45[/tex]

the resulting angles would be [tex]45, 90, 45[/tex] and these add up to [tex]180[/tex]°

Answer:

y = [tex]-\frac{1}{5}x[/tex] - 4

Step-by-step explanation:

As we know the point slope form of an equation is as follows -

y - y₁ = m ( x - x₁ )

As we have slope , m = [tex]-\frac{1}{5}[/tex]

And point (x₁ , y₁ ) = ( -5, -3)

⇒ y - ( -3) = [tex]-\frac{1}{5}[/tex] ( x - (-5) )

⇒ y + 3 = [tex]-\frac{1}{5}[/tex] ( x + 5 )

⇒ y + 3 = [tex]-\frac{1}{5}[/tex] x - 1

⇒ y =  [tex]-\frac{1}{5}[/tex] x - 1 - 3

⇒ y =  [tex]-\frac{1}{5}[/tex] x - 4

So, the equation becomes

y = [tex]-\frac{1}{5}x[/tex] - 4

Answer:

30

Step-by-step explanation:

90+2x+x=180

3x=90

x=30

Answer:

30

Step-by-step explanation:

First we can find the total angle that we are "adding" to. This total angle is 180 degrees. Now since there is a right angle, H,E,G, we can remove 90 from that total to get 90. Now for x. Since there is a total of 3 x's, we divide 90 by 3 to get 30.

Answer:

4

Step-by-step explanation:

1.25(4x-10)=7.5

First step is to divide the 1.25 on both sides

4x-10 = 6

next step is to get x by itself by adding 10 to both sides

4x = 16

continue getting x by itself by dividing both sides by 4

x = 4.

First begin with the interest formula.

Interest = Principal x Rate x Time

The $250 is the principal is the amount of money invested.

The rate is 4% which translates to the decimal .04.

The time is 5 years.

So we have I = (250)(.04)(2).

Multiplying, (25)(.04) is 10 and we have 10(2) which is 20.

This means that the interest earned in 2 years is $20.

Answer:

57

Step-by-step explanation:

Hey there!

To find the solution, plug in 5 for y. When you do this you get, 7+2(5)². Square the 5 to get 25. And then you att 7+2(25). 25 x 2 is 50. 50 +7 is 57.

Answer:

362.35N/m²

Step-by-step explanation:

Pressure = Force/Area

Area = πr²

Area = 3.14(0.75)²

Area = 3.14(0.5625)

Area = 1.76625m²

Force = 640N

Pressure = 640/1.76625

Pressure = 362.35N/m²

Answer

It is the first answer.

Step-by-step explanation:

Parallel lines are lines that will never cross each other.

Perpendicular lines are lines that cross each other at 90 degree angles (represented by the box in the corner).

A set of parallel lines and a set of perpendicular lines in this image are; AB║CD, CD ⊥ EF and AB ⊥ EF

Parallel lines have the same slope since the slope is like a measure of steepness and since parallel lines are of the same steepness, thus, are of the same slope.

Since Parallel lines are lines that will never cross each other.

We know that Perpendicular lines are lines that cross each other at 90 degree angles.

The parallel lines are AB and CD, the perpendicular are AB and EF because the first sets are side by side and the second sets cross each other at a certain point.

Therefore the  set of parallel lines and a set of perpendicular lines in this image are; AB║CD, CD ⊥ EF and AB ⊥ EF

Answer:

im bad at math sawy

Step-by-step explanation:

Answer:

y = 2x

Explanation:

To write the equation of a line u use the formula y = mx + b, where

y = y coordinate

m = slope

x = x coordinate

b = y intercept

One thing about parallel lines is that they always have the same slope. If you want to find a line parallel to y = 2x + 3, then the parallel line will also have a slope of 2.

So far, then, the equation would look like this: y = 2x + b

To find the y-intercept, we substitute in the values from (3,6) into the equation because the line passes through that point. So:

y = 2x + b

(6) = 2(3) + b

6 = 6 + b

6 - 6 = b

b = 0

Since the y-intercept is 0 (so the line passes through the origin), it doesn't need to be written on to the end of the equation.

y = 2x + 0 is just

y = 2x

That's your final equation! hope this helps!

Answer:

44

Step-by-step explanation:

1. Find out how many coins were foreign

x.           84

------ = ---------

275.      100

2. Subtract 231 (Foreign coins) by 275 (Total coins)

3. The answer is 44

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

The number of foreign coins.

84% of 275 = 231

The number of foreign coins is 231.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Total number of coins = 275

Percentage of foreign coins = 84%

The number of foreign coins.

= 84% of 275

= 84/100 x 275

= 231

Thus,

The number of foreign coins is 231.
