Answer:

a)hemant is correct

b) they didn't solve this according to BoDMAS so they got wrong answer

a) The student Hemant's answer -29 is the correct answer, b) The errors they make is the change of sign in the first step.

Simplification of an expression is the process of writing an expression in the most efficient and compact form without affecting the value of the original expression. It involves, multiply out the brackets and then simplify the resulting expression by collecting the like terms.

For the given situation,

The expression is {-10-3(10÷2)}-4

⇒ [tex][-10-3(\frac{10}{2} )]-4[/tex]

⇒ [tex][-10-3(5)]-4[/tex]

⇒ [tex][-10-15]-4[/tex]

⇒ [tex][-25]-4[/tex]

⇒ [tex]-29[/tex]

a) The student Hemant's answer -29 is the correct answer.

b) The student Diyoshana did mistake in sign in step 1 as

⇒ [tex][-10+3(\frac{10}{2} )]-4[/tex]

⇒ [tex][-10+15]-4[/tex]

⇒ [tex]5-4[/tex]

⇒ [tex]1[/tex]

The student Rupesh did mistake in sign in step 1 as

⇒ [tex][10+3(\frac{10}{2} )]-4[/tex]

⇒ [tex]25-4[/tex]

⇒ [tex]21[/tex]

Hence we can conclude that a) The student Hemant's answer -29 is the correct answer, b) The errors they make is the change of sign in the first step.

Answer:

There are 3,900 tickets of $28 each and 1,100 tickets of $40 each sold.

Step-by-step explanation:

x = the number of $28 tickets

y = the number of $40 tickets

x + y = 5000

28x + 40y = 153200

x = 3,900 tickets

y = 1,100 tickets

Answer:

sound great so whats your question

Step-by-step explanation:

Based on the SAS similarity theorem, the right option is: C) ΔVML ∼ ΔUMT.

In order to determine if two triangles are similar, find out if the ratio fo their corresponding side lengths are equal, that is, their lengths must be proportional to each other if they are similar triangles.

The SAS states that if two pairs of sides of two triangles are proportional to each other, and they have a pair of corresponding congruent included angles, then they are similar triangles.

Given the image showing the two triangles, we have the following measures:

VM = 14, which is corresponding to UM = 49

LM = 8, which is corresponding to TM = 28

VM/UM = 14/49 = 2/7

LM/TM = 8/28 = 2/7

This means the two sides are proportional.

Also, angles VML and UMT are congruent to each other based on the vertical angles theorem.

Therefore, we can state that the ΔVML ∼ ΔUMT by SAS. The right option is C.

Answer:

No

Step-by-step explanation:

Inverse f(x) into f(x)^-1.

x = 2y + 4

Solve for y.

x -4 = 2y

x/2 - 2 = y

y = x/2 - 2

No.

The absolute value of inequality is 180 ≤  x ≤  200 and its solution lies in [180, 200].

Linear inequality refers to the relation between a linear algebraic expression to some known value that contains inequality sign.

Unlike a linear equation it can have a range of values inside an interval.

Suppose the operating temperature be x.

Then, as per the question the absolute difference of the temperature and 190°F is within 10°F.

It can be written in the form of inequality as follows,

|x - 190| ≤ 10

⇒ x - 190 ≤ 10 and  x - 190 ≥ -10

⇒ -10 ≤ x - 190 ≤ 10

⇒ -10 + 190 ≤ x ≤ 10 + 190

⇒ 180 ≤  x ≤  200

Thus, the range of acceptable temperatures lie in [180, 200].

Hence, the absolute value of inequality and its solution are given by  180 ≤  x ≤  200 and [180, 200] respectively.

Answer:

x = - 11

Step-by-step explanation:

Take the square root of both sides.

sqrt(x+4)^2 = sqrt(49)

x + 4 = +/- 7

x + 4 = + 7

x = 3                 Not what you want.

x + 4 = - 7

x = - 11

1/4 × s = 15

s = 15 : 1/4

s = 15 × 4

s = 60

[tex]\boxed{\underline{\bf \: ANSWER}}[/tex]

[tex] \sf \: \frac{1}{4s} = 15 \\ [/tex]

Variable s cannot be equal to 0 as division by zero is not defined. Multiply both sides of the equation by 4s.

[tex] \sf \: 1=60s [/tex]

Swap sides so that all variable terms are on the left-hand side.

Answer:

Value of k is 9

Step-by-step explanation:

-2x + 8 = -10

-2x = -10 - 8

-2x = -18

x = -18/-2

x = 9

f(x) = f(k)

x = k

9 = k

Hello there!

We are given the function:

[tex] \displaystyle \large{f(x) = - 2x + 8}[/tex]

We want to find the value of k. First, we know that f(k) is -10. We substitute x = k and f(x) = -10.

[tex] \displaystyle \large{f(k) = - 2k + 8} \\ \displaystyle \large{ - 10 = - 2k + 8}[/tex]

Solving the equation. First, we subtract both sides by 8.

[tex] \displaystyle \large{ - 10 - 8 = - 2k +8 - 8} \\ \displaystyle \large{ - 18 = - 2k} \\ [/tex]

Divide both sides by -2.

[tex] \displaystyle \large{ \frac{ - 18}{ - 2} = \frac{ - 2k}{ - 2} } \\ \displaystyle \large{ 9= k}[/tex]

Therefore, k = 9

When we substitute k = 9 in f(k), the value is -10.

Answer:

∠ 1 = 36°

Step-by-step explanation:

Supplementary angles sum to 180° then

∠ 2 + ∠ 3 = 180° , that is

∠ 2 + 126° = 180° ( subtract 126° from both sides )

∠ 2 = 54°

Complementary angles sum to 90° , then

∠ 1 + ∠ 2 = 90° , that is

∠ 1 + 54° = 90° ( subtract 54° from both sides )

∠ 1 = 36°
