added together is 11, divide 99 by 11 to get 9, multiply the ratio numbers by 9

54:27:18

Check answers:

27 times 2 = 54     yes

18 times 3 = 54      yes

Answer:

  3x +4

Step-by-step explanation:

Polynomial long division is done the same way numerical long division is done.

The next quotient term is found by dividing the highest-degree dividend term by the highest-degree divisor term. The result is the exact quotient term. There is no need to go back and make an adjustment as there sometimes is with numerical long division.

Once you have the quotient term, you multiply that by the divisor and subtract from the dividend. This is the same procedure as is used with numerical long division. The difference is the new dividend, and the process repeats.

When the dividend is lower-degree than the divisor, that dividend is the remainder. For this division, the remainder is zero, so the quotient has no fractional part.

__

Both the quotient and the divisor can have any degree and any number of terms. It is useful to write both so all powers of the variable are accounted for, using 0 as a coefficient where necessary. This helps keep things straight when you're multiplying and subtracting. As you know, only "like" terms (terms of the same degree) can be combined by addition or subtraction.

Answer:

The estimate is too low

Step-by-step explanation:

46×6=276 which isn't a very close estimate. However if you used 46×7=322 the estimate would be OK. Now if you used 46×8=368 that would be too high of an estimate here. In simpler terms 1 to 6 is too low of an estimate here and 8 to 9 is too high of an estimate. The number 7 is the middle ground here. Hope this helped.

(3p-p)/(2-(-8))= -3

2p/10= -3

2p= -30

p= -15

Answer:

-15

Step-by-step explanation:

Given that a line has a slope of -3 and passes through the points (-8,p) and (2,3p) . And we need to find out the value of p . As we know that the slope is ,

[tex]\longrightarrow\sf slope = y_2-y_1/x_2-x_1[/tex]

Substituting the respective values ,

[tex]\longrightarrow[/tex] -3 = (p - 3p)/(-8-2)

Simplify ,

[tex]\longrightarrow[/tex] -3 = -2p/-10

[tex]\longrightarrow[/tex] -3 = p/5

Answer:

  (d)  18

Step-by-step explanation:

If ΔJKL ~ ΔPQR, then we must have ...

  PQ/JK = QR/KL . . . . . ratios of corresponding sides are the same

  PQ = JK×QR/KL = 12×9/6 = 2×9

  PQ = 18

Answer:

18

Step-by-step explanation:

The scale factor for this is 1.5,

JL = PR

JL is 14, and PR is 21, 14 * 1.5 = 21

KL = QR

KL is 6, and QR is 9, 6 * 1.5 = 9

So we do the same for JK and PQ

Since PQ is 12, we need to find what 12 * 1.5 is.

12 * 1.5 = 18

PQ = 18

Answer:

  see attached

Step-by-step explanation:

The equation is given in "slope-intercept" form.

  y = mx + b

where m is the slope, and b is the y-intercept.

__

For graphing, it is usually convenient to start with the y-intercept. The value of 'b' in your equation is +1, so the graph will go through the point y=1 on the y-axis. That point's coordinates are (0, 1).

The value of m represents the slope, or "rise"/"run" of the line. A slope of -2/3 means the line "rises" -2 units for each "run" of 3 units to the right. Then another point on the graph will be 3 units to the right of the y-axis, and 2 units down from y = 1. That point is (3, -1).

The line is drawn through these points you found on the graph.

Answer:

veriable constant variable

Step-by-step explanation:

took the test

The constant term is 2 and the variable terms are '9gh' and 'g' in the given polynomial.

A polynomial expression is an algebraic expression with variables and coefficients. Unknown variables are what they're termed. We can use addition, subtraction, and other mathematical operations. However, a variable is not divisible.

The polynomial is given below.

⇒ 2gh + 2 + g

In the above polynomial, the letter 'g' and 'h' are variables.

The constant term is that term in which no variable is there. Then the constant term is 2.

And the variable terms are '9gh' and 'g'.

Translation involves changing the position of a point in the coordinate plane.

The coordinate of  the translated point A' is (D) (0,0)

The coordinate of the point is given as:

[tex]A = (-9,-1)[/tex]

The rule of translation 9 units right, and 1 unit up is:

[tex](x,y) \to (x+9,y+1)[/tex]

So, we have:

[tex]A' = (-9+9,-1+1)[/tex]

Simplify the expression

[tex]A' = (0,0)[/tex]

Hence, the coordinate of  the translated point A' is (D) (0,0)

https://brainly.com/question/18549175

If the coordinate is translated 9 units right and 1 units up, the resulting coordinate will be at (-9 + 9, -1 + 1) which is A'(0, 0). Option D is correct

Given the coordinate point A (x, y),  if the coordinate is translated a unit right and b units up, the resulting coordinate will be at (x + a, y + b)

Note that both values are added to the coordinate points.

Given the coordinate point A (-9, -1), if the coordinate is translated 9 units right and 1 units up, the resulting coordinate will be at (-9 + 9, -1 + 1) which is A'(0, 0)

Step-by-step explanation:

Answer:

The answer would be $1.89 in interest.

Step-by-step explanation:

First, change 10.5% into a decimal. To do this, you divide 10.5÷100. This equals 0.105

next, you multiply 0.105 with 12 (12 months in a year)

This equals 1.26

But, Hector still has 6 months left he has to pay for.

So, one way you can do this is divide 1.26 by 2, which equals 0.63.

THEN, you add 0.63 with 1.26, giving you the answer, 1.89

So, the answer for this equation would be 1.89.
