Answer 1

Answer:

x=11, y=13

Step-by-step explanation:

3x-2y=7

3x-2(x+2)=7 .          - x + = -      -2*+2=-4

3x-2x-4=7

1x-4=7

x=7+4

x=11

y=x+2

y=11+2

y=13

Answer 2
Answer:
(11, 13)
Explanation:
The first step when you multiply -2 times 2 would equal -4
Then you would
3x-2x-4=7
x-4=7
x=11
y=x+2
y=11+2
y=13
The error Carolyn made was not multiplying the negative and positive number right.

Answers

Answer:

72.25

Step-by-step explanation:

Triangles are 1/2(base x height), or (base x height) / 2.

17 x 8.5 = 144.5

144.5 / 2 = 72.25

74.25 square inches.

The formula to find the area of a triangle is A = 1/2(b)(h). (b being base and h being height)

A=1/2(17)(8.5)
A=1/2(144.5)
A= 72.25 :)

Answers

Answer:

x = -7

y = 42

Step-by-step explanation:

y = -6x

y = -8x - 14

substitute -6x in the second equation for y

-6x = -8x - 14

add 8x to both sides

2x = -14

divide both sides by 2

x = -7

----------------

substitute that in to the first equation to solve for y:

y = -6(-7)

y = 42

----------------------------------

check the math:

y = -8x - 14

42 = -8(-7) - 14

42 = 56 - 14

42 = 42

3053.63=πr^2h

what is h?

Answers

Answer:

h = 12

Step-by-step explanation:

3053.63=πr^2h

Let r=9 and approximate pi as 3.14

3053.63=3.14 ( 9)^2 h

3053.63=3.14*81*h

3053.63=254.34h

Divide each side by254.34

3053.63/254.34=254.34h/254.34

12=h

Answer:

[tex] h = \dfrac{3053.63}{\pi r^2} [/tex]

Step-by-step explanation:

3053.63 = πr²h

Switch sides.

πr²h = 3053.63

Divide both sides by πr².

h = 3053.63 / πr²

Terms are the numbers and variables that are usually separated by an addition sign or a subtraction sign. In the expression 2x, 3y, 5z, and 4 are all terms.

Variables are the letters that come after a number. They represent the unknown number in the equation. The x, y, and z in the expression are the variables.

Coefficients are the numbers in front of the variables. For example, 2, 3, 5, and 4 are the coefficients.

The constants are the "signs" in between the terms. These include the addition sign and the subtraction sign.

Explain a real world example of a combination where repetition is allowed. You need to EXPLAIN WHY, not just give an example.

Answers

Answer:

Combinations refer to the combination of n things taken k at a time without repetition. To refer to combinations in which repetition is allowed, the terms k-selection, k-multiset, or k-combination with repetition are often used.

Step-by-step explanation:

in smaller cases it is possible to count the number of combinations. For example given three fruit, say an apple, orange and pear, there are three combinations of two that can be drawn from this set: an apple and a pear; an apple and an orange; or a pear and an orange.
