Answer:

27: -5/11

28: 4x^2+12x

29: (2b-7c+5a)(2b-7c-5a)

30: 2/3

Step-by-step explanation:

27 is pretty simple, start by multiplying both sides by 6

so we have 2(6y+1)=y-3

this equal 12y+2=y-3

Subtract 1y and 2 from both sides to get

11y=-5

divide and get y= -5/11

28: this one is a lot to write so if you need me to explain it leave a comment but I got 4x^2+12x

29: Same deal as 28

(2b-7c+5a)(2b-7c-5a)

30: For this one I just distributed then combined like terms to get y=2/3

Answer:

For which equations does the fraction 23 make the equation true? Select all that apply.

35 × □ = 20; I rewrote 35 as 351 and then multiplied 2 and 35 to get the numerator, and I multiplied 3 and 1 to get the denominator.

26 × □ = 18126; I rewrote 26 as 126 and then multiplied 1 and 2 to get the numerator, and I multiplied 3 and 26 to get the denominator.

48 × □ = 32; I rewrote 48 as 481 and then multiplied 2 and 48 to get the numerator, and I multiplied 3 and 1 to get the denominator.

22 × □ = 1423; I rewrote 22 as 221 and then multiplied 2 and 22 to get the numerator, and I multiplied 3 and 1 to get the denominator.

23 × □ = 15; I rewrote 23 as 123 and then multiplied 2 and 1 to get the numerator, and I multiplied 23 and 3 to get the denominator.

Simplify x²-49/3x+21
Vera_Pavlovna [14]
First, you factor and simplify (respectively) the numerator and denominator. Your equation becomes:

\frac{(x-7)(x+7)}{3(x + 7)}

Notice, there is a (x + 7) on both the top and the bottom. Because of this, they cancel each other out. What is left is your answer:

\frac{(x-7)}{3}

F it costs $90 to feed a family of 3 for one week. (3 points)
Nataly [62]
Given:
$90 good for 3 pax for 1 week.

a) $90 / 3 = $30 cost to feed each person in a week
b) $30 cost to feed each person * 5 persons = $150
c) $30 cost to feed each person * 6 persons in a family = $180 

The formula derived from the above facts is:

Total cost = cost per person * no. of person * no. of weeks.

Assuming = 6 persons for 2 weeks
Total cost = 30 x 6 x 2
Total cost = 180 x 2
Total cost = 360 cost to feed a family of 6 in 2 weeks.

Vertical angles 4x+7 and [5(x-4)] what is the value of x
choli [55]

Answer:

x = 27

Step-by-step explanation:

vertical angles are congruent , then

5(x - 4) = 4x + 7 ← distribute parenthesis on left side

5x - 20 = 4x + 7 ( subtract 4x from both sides )

x - 20 = 7 ( add 20 to both sides )

x = 27
