Answer:

$\bf x=5$

Step-by-step explanation:

$\bf 2x - x + 3x + 5 = 25$

Combine like terms.

$\bf 4x+5=25$

Subtract 5 from both sides.

$\bf 4x+5-5=25-5$

$\bf 4x=20$

Divide both sides by 4.

$\bf \cfrac{4x}{4}=\cfrac{20}{4}$

$\bf x=5$

A theater can seat 273 people. The number of rows is 8 less than the number of seats in each row. How many rows of seats are the

artcher [175]

R * s = 273
r = s - 8.....s = r + 8

r(r + 8) = 273
r^2 + 8r = 273
r^2 + 8r - 273 = 0
(r - 13)(r + 21) = 0

r - 13 = 0
r = 13

r + 21 = 0
r = -21.....extraneous solution...not ur answer

r = 13
s = r + 8 = 13 + 8 = 21

so there are 13 rows.....each row containing 21 seats

16. Suppose Eva has 12 3/4 pounds of flour. The day's baking will require triple that amount.

egoroff_w [7]

Answer:

Option D

Step-by-step explanation:

Given the following question:

$12 \frac{3}{4} \times3$

In order to find the answer, we have to convert the mixed number and then multiply by three, since how Eva needs triple the amount for today's baking.

$12 \frac{3}{4} \times3$
$12\frac{3}{4} =4\times12=48+3=51=\frac{51}{4}$
$3=\frac{3}{1}$
$\frac{51}{4} \times\frac{3}{1}$
$51\times3=153$
$4\times1=4$
$=\frac{153}{4}$

Convert the improper fraction back into a mixed number:

$\frac{153}{4}$
$\frac{153}{4} =153\div4=38\frac{1}{4}$
$=38\frac{1}{4}$

Which means Eva needs "38 1/4 pounds of flour" or option D for today's baking.
