evelyn read 25 pages of a book on friday morning. she read 1/4 of the remainder on friday afternoon if she still had 90 pages to read after friday afternoon .how many pages were in the book

Answers

Answer 1

Answer: 145 pages.

25 + 1/4 x (X - 25) + 90 = X

100 + X - 25 + 360 = 4X

435 + X = 4X

435 = 3X

X = 145

Ok so we are calling the total number of pages in the book X. Friday morning, they read 25 pages. Friday afternoon, they read 1/4 of what is left. Since they already read 25 pages, we can say that the remainder of the pages is the total, X, minus 25, giving us the amount of pages read on Friday afternoon 1/4 (X - 25). They then say that the rest of the pages in the book after Friday is 90. Therefore what they read of friday plus 90 is the total amount of pages in the book. After this point, it is simple algebraic solving in order to find X. If you plug 145 in for the total amount of pages, you will see that it works.

The lines are parallel ( they have the same slope)

the slope is 1/2 ( up 1 over 2)

The y intercept is different.

The lines will never intersect.

Therefore there are zero solutions

alicia paid $1.32 for a bag of pinto beans .the beans cost $.55per lb .how much did the bag of pinto beans weight?

Answers

Answer:

2.4 pounds.

Step-by-step explanation:

We have been given that Alicia paid $1.32 for a bag of pinto beans. The beans cost $0.55 per lb. We are asked to find the weight of pinto beans bag.

To find the weight of pinto beans bag, we will divide amount paid for the bean bag by per pound of beans.

$\text{Weight of pinto beans bag}=(1.32)/(0.55)$

$\text{Weight of pinto beans bag}=2.4$

Therefore, the weight of pinto beans bag is 2.4 pounds.

the bag weighed 2.4 pounds heres how you solve

1.32/.55=2.4 pounds

so if you have a right triangle with legs legnth a and b and a hypotonuse legnth c, then a^2+b^2=c^2 given in the comments is that a=15 c=20 input and solve 15^2+b^2=20^2 225+b^2=400 subtract 225 from boths ides b^2=175 take square root of both sides b=5√7

The therorem is:

$a^(2) + b^(2) = c^(2)$
or, solving for b:
$b = \sqrt{c^(2)-a^(2)}$

$b = \sqrt{20^(2)-15^(2)}$
$b = √(400-225)$
$b = √(175)$
$b \approx 13.23$

How do you solve this problem 4 5/10 + 6 9/10=

Answers

4 5/10
+6 9/10
10 14/10
simplify it to 11 1/10
ANSWER=11 1/10

First, ignore the whole numbers and come back to them later. Add the numerators which is 5+9= 14. Keep the common denominator the same so it would equal 14/10. Make 14/10 into a mixed number which is 1 4/10. Simplify the 4/10 to 2/5 so now you have 1 2/5. Now come back to the whole numbers 4+6= 10. Finally add 10+1 2/5. Your answer is 11 2/5.
