If x + 2 = y, what is the value of x - 2 in terms of y? *
1. Y+2
2. Y-4
3. Y+4
4. Y+6

Answers

Answer 1
2

Y - 4 is the awnser, just imagine x is 2, 2 plus 2 is four, and 2 minus 2 is 0, so if four is y then y - 4 = x - 2

Find the value of d and FG if:

Answers

Answer:

The value of x = 8.5

The value of FG = 8.5 units

Step-by-step explanation:

Given

F is between E and G.EF = 7FG = 2(x - 5)EG = 3(x-4)

Determining the value of x

As F is between E and G, so

EF = FG

7 = 2(x-5)

7 = 2x-10

2x = 7+10

2x = 17

divide both sides by 2

2x/2 = 17/2

x = 8.5

Thus,

The value of x = 8.5

Determining the value of FG

As

FG = 2(x-5)

substituting x = 8.5

FG = 2(8.5 - 5)

FG = 2(3.5)

FG = 7

Thus,

The value of FG = 8.5 units

Summary:

The value of x = 8.5

The value of FG = 8.5 units

A hairstylist charges $15 for an adult haircut and $9 for a child haircut

She wants to earn $360 dollars

15x+9y= 360----------1

and cut 30 haircuts this week

x+y= 30--------------2

Step two:

Hence the system of equations for the situation is given as

Use properties of operations to complete the equivalent expressions.

Answers

Answer:

Answer is explained below in the explanation section.

Step-by-step explanation:

Note: This question is very generic and incomplete. So, I will be using the general properties of operation for a general expressions for the sack of understanding and concept.

Solution:

There are several properties of arithmetic operations. But here, we will be discussing about the common properties of operations.

1. Commutative property of Addition

2. Commutative property of Multiplication

3. Associative property of Addition

4. Associative property of Multiplication

Let's Start,

1. Commutative property of Addition:

a + b = b + a

it means that if we add 2 to 3 or 3 to 2, the result will be same.

2 + 3 = 3 + 2

5 = 5

Similarly.

2. Commutative property of Multiplication:

a x b = b x a

it means that if we multiply 2 to 3 or 3 to 2, the result will be same.

2 x 3  = 3 x 2

6 = 6

3. Associative property of Addition:

Let's suppose we have 3 variables now,

a, b and c

so,

a + (b + c)  = (a + b) + c

2 + (3 + 5)  = (2 + 3) + 5

2 + (8) = (5) + 5

10 = 10

Similarly.

4. Associative property of Multiplication:

a x (b x c)  = (a x b) x c

2 x (3 x 5)  = (2 x 3) x 5

2 x ( 15) = (6) x 5

30 = 30

Hence, these operations are very useful in solving the bigger and complex questions in mathematics.

How do I find angle A?

Answers

50 + 12x - 7 + 6x + 11 = 180
18x + 54 = 180
18x = 126
x = 7 degrees

Angle A = 6x + 11
Angle A = 6(7) + 11
Angle A = 42 + 11
Angle A = 53 degrees

Angle A (6x +11)  = 53

12x - 7 = 77

Alvin is 10 years younger than Elga. The sum of their ages is 50 . What is Elga's age?

Answers

The sum of their ages is 50 so x + y = 50

If x - 10 = y then y + y + 10) = 50

50 = 2y +10

Subtract ten from both sides

40 = 2y

Divide by 2

Y = 20

And remember x - 10 = y

Then x - 10 = 20

Add 10 to both sides

X = 30

ANSWER: Alvin is 20, Elga is 30

Aria´s height is 3 inches less than her brother´s height. her brother´s height is unknown.

Answers

We can not find the answer unless we have the height of the brother.

The answer is x-3. We don't know the brother's height, so we make it into a variable. You may pick any variable, but x is a common choice. We then subtract 3 from x, which would give us Aria's height. Since we don't know the height of the brother, we won't know Aria's height.

Karen and Tom sold candy bars for a fundraiser, Karen sold 7 less than twice the number of candy
bars that Tom sold. In total, Karen and Tom sold 137 candy bars. Find the amount of candy bars
sold by each

Answers

Answer:

89

Step-by-step explanation:

Create two formulas and use substitution.

K = 2c -7 (89)
T = c (48)
Substitute

K + T = 137

2c-7 + C = 137 (Group)
3c-7 = 137 (Add 7 to both sides)
3c = 144 (divide by 3)
C = 48 (Substitute to each individual)

2(48) -7 = 89
