if the first and third of three consecutive odd integers are added, the result is 75 less than five times the second integers. f

Anastaziya [24]

Answer:

The third integer is 27

Step-by-step explanation:

Given

Represent the consecutive odd numbers with $T_1, T_2; and\ T_3$

Since they are consecutive odds, then

$T_2 = 2 + T_1$

$T_3 = 2 + T_2$

From the first statement in the question, we have that

$T_1 + T_3 = 5 T_2 - 75$

Required

Find the third integer

Recall that

Substitute $T_2 = 2 + T_1$ in $T_3 = 2 + T_2$

$T_3 = 2 + 2 + T_1$

$T_3 = 4 + T_1$

Substitute $T_3 = 4 + T_1$ and $T_2 = 2 + T_1$ in $T_1 + T_3 = 5 T_2 - 75$

$T_1 + 4 + T_1 = 5(2 + T_1) - 75$

Open Brackets

$T_1 + 4 + T_1 = 10 + 5T_1 - 75$

Collect like terms

$T_1 + T_1 + 4 = 5T_1 - 75 + 10$

$2T_1 + 4 = 5T_1 - 65$

Collect like terms

$2T_1 - 5T_1 = - 65 - 4$

$-3T_1 = - 69$

Divide both sides by -3

$\frac{-3T_1}{-3} = \frac{- 69}{-3}$

$T_1 = 23$

Recall that $T_3 = 4 + T_1$

$T_3 = 4 + 23$

$T_3 = 27$

The third integer is 27

Match the ones that are highlighted please:(

The answers are 2. B, 3. D, 4. C, and 5. A.

Step-by-step explanation:

Step 1:

For question 2. $4+4n = -12.$

We subtract both sides by 4 to get

$4+4n-4 = -12-4, 4n = -16, n = -4$

For question 3. $4n=-12$ .

We divide the entire equation by 4 to get

$\frac{4n}{4} = \frac{-12}{4} , n = -3.$

Step 2:

For question 4. $\frac{n}{4} = -12.$

We multiply both sides by 4 to get

$\frac{n}{4} (4)= -12(4).$

$n = -48.$

For question 5. $\frac{n}{4} -4 = -12.$

We add 4 to both sides to get

$\frac{n}{4} -4 +4= -12+4, \frac{n}{4} = -8.$

$n = -32.$

So the answers are 2. B, 3. D, 4. C, and 5. A.

Find the equation for the line that passes through the point (2,2), and that is parallel to the line with the equation y=3/4x-4

telo118 [61]

Answer: y=3/4x + 1/2

Step-by-step explanation: Parallel lines must have the same slope, so you already know the equation must be something like y=3/4x+b. You are given a point that the line goes thru(2,2), so you can plug this point into the equation to solve for b.

(2)=3/4(2) + b

2=6/4 + b

2= 3/2 + b

b= 2-3/2

b=4/2- 3/2

b=1/2

so y=3/4x + 1/2
