Equality Properties

Step-by-step explanation:

Step 1: Define equation

4x - 5 = x - 1 + 3x

Step 2: Solve for x

Here we see that -5 does not equal -1.

∴ This equation has no solutions.

Answer: in each group, there are 8 students.

Step-by-step explanation:

We have a total of 26 students.

If we separate them into 3 equal groups (suppose that each group has X students) and leave 2 students left, we will have the relation:

3*X + 2 = 26

This means that 3 times the number of students in each group, plus the two students leftover must be equal to the initial number of students.

Now we can solve this for X.

3*X + 2 = 26

3*X = 26 - 2 = 24

X = 24/3 = 8

X = 8

This means that in each group there are 8 students.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

(8 + 9) + 3 is equivalent to 8 + (9 + 3) using the property of associative.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

(8 + 9) + 3 = 17 + 3 = 20

8 + (9 + 3) = 8 + 12 = 20

This is the property of associative.

Thus,

(8 + 9) + 3 is equivalent to 8 + (9 + 3) using the property of associative.

Answer:

Step-by-step explanation:

A of base: l ×w =5×4=20cmsquared

Missing length of c=a+b=c

C=6+2

C=8cm

A of side 1= b×h÷2 ×2

= 5×8÷2×2

= 40 ÷2×2

=20 ×2

= 40 cm squared

A of side 2= b×h÷2×2

Answer:

x ≈ 14.7

Step-by-step explanation:

use pythagorean therorem

a^2 + b^2 = c^2

c is hypotenuse and we know the hypotenuse is 21

a^2 + b^2 = c^2

x^2 + 15^2 = 21^2

x^2 + 225 = 441

x^2 = 216

x = √216

x ≈ 14.7

Step-by-step explanation:

2 - 5 = -3

Answer:

-5x + 11

Step-by-step explanation:

All you're doing is substituting.

f(x)=-2x+3

f(1-x) = 2(1-x)+3

= 2 - 2x +3

= -2x + 5

g(x)=3x+3

g(1-x) = 3(1-x)+3

= 3 - 3x + 3

= -3x + 6

Now add them together and combine like terms:

f(1-x) + g(1-x)

-2x + 5 + -3x + 6

= -5x + 11

Answer:

  marked price = Rs. 3900

Step-by-step explanation:

The difference between the discounts is 30% -20% = 10% of the marked price. The difference in Rs is 120 -(-270) = 390. If Rs. 390 is 10% of the marked price, then the marked price is (Rs. 390)/(0.10) = Rs. 3900.

The marked price is Rs. 3900.

_____

Check

A 20% discount from 3900 is a price of 3120. If the profit is 120, the cost price is 3000. A 30% discount from 3900 is 2730. This is 270 below the 3000 cost price, so our answer is consistent with problem requirements.

Answer:

350 girls

Step-by-step explanation:

So,

The secret to solving problems with ratios is to find the value of one unit.

5:7 = 12 units total

To find one unit, divide the total number of students by the total number of units.

600/12 = a

Simplify

50/1 = a

50 = a

The value of each unit is 50.

Now, multiply the units by the numbers in the ratio.

50(5) = b

250 = boys

50(7) = x

350 = x

There are 350 girls.

The categories that are graphed on a circle usually represent the percentage. Option C is correct.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,
A circle graph represents the percentage fraction, and a pie chart is the form of a circle graph, Where a whole circle represents the 100% composition of the entities and data set.

Thus, the categories that are graphed on a circle usually represent the percentage. Option C is correct.

Step-by-step explanation:

5x - 7 = 19

Add 7 to both sides:

5x = 26

Divide both sides by 5:

x = 26/5

[tex]5x - 7 = 19[/tex]

Move -7 to another side and become + 7. Whenever we move to another side, we change the sign/operator to opposite. Ergo, changing from plus to minus and multiply to divide.

[tex]5x = 19 + 7 \\ 5x = 26[/tex]

We are at this part. Now to move 5 which is multiplying the x. So we move 5 from multiply to divide 26.

[tex]x = \frac{26}{5} [/tex]

Ergo, the answer is x = 26/5
