Answer 1

Answer:

see below

Step-by-step explanation:

65 - 32 = 13

13 divide by 65 = 0.20

0.20 x 100% = 20%

so the percentage drop is 20%

therefore, Marcus is correct.

Three consecutive odd numbers sum to 1,245. What are the three numbers? ​

Answers

Answer:

413, 415, 417

Step-by-step explanation:

Answer:

414, 415, 416

Step-by-step explanation:

Consecutive numbers means they come one after another, like 1,2,3,4,5... So they all follow the formula x, x+1, x+2, x+3...x+n.

Since there are 3, we can say that x+(x+1)+(x+2)=1,245.

Simplify that to 3x+3=1,245, and then subtract 3 from both sides.

We get 3x=1,242. Divide that by 3, and you get x=414.

Add 1 and 2 to 414, and you get 414, 415, and 416.

You can add them up to check.

If 7/9x - 4/9x = 1/4 +5/12
what is the value of x?

Answers

Answer:

x=2

Step-by-step explanation:

subtract 7/9x -4/9x

3/9x= 1/4 +5/12

first change 1/4 to 3/12

then add 3/12 + 5/12

3/9x = 8/12

change 3/9x to 1/3x then to 4/12x

4/12x = 8/12

then mulitiply by the reciprical 12/4 on both sides

x = 2

−4x+7=17

−4x+7+−7=17+−7(Add -7 to both sides)

−4x=10

(Divide both sides by -1)

4x=−10

4x=−10(Solve Exponent)

log(4x)=log(−10)(Take log of both sides)

x*(log(4))=log(−10)

SOMEONE PLEASE HELP I CANT GET IT

Answers

Answer:
y=3x+9

Explanation:
To answer this question, we first have to understand a few key concepts.

1) The equation given (y=3x+9) is written in slope-intercept form, which is y=mx+b.

Heres what the variables mean:
Y=the coordinate
M=the slope
X=the x coordinate
B=the y-intercept (the point on the line that intercepts the y-axis)

2) Parallel lines have the same slope. Using the given equation, we now know that the slope of line s is 3. Therefore, the slope of line t is also 3 (because they are parallel).

So now, this is our equation so far:
y=3x+b

All we need to do now is find b, which we can do by plugging in the coordinate (-6,-9) as the x and y variables.

y=3x+b
-9=3(-6)+b
-9=-18+b
Add 18 to both sides
-9+18=-18+b+18
9=b

And when we plug 9 into y=3x+b, we get:
y=3x+9

(And yes, they are pretty much the same line)

I hope this helps! Please comment if you have any questions.
