Nick has $7.00. Bagels cost $0.75 each, and a small container of cream cheese costs $1.29. Write an inequality to find the numbers of bagels Nick can buy. Identify what your variable represents

Answers

Since the question only asks for bagels, put the cream-cheese idea aside.
The total spent has to be less than $7 so an equation can be this: $0.75x<$7 where x is the number of bagels

ballance method is just a fance method of helping you remember to DO THE SAME THING TO BOTH SIDES OF AN EQUATION to keep it ballanced

-10=2(-3x+1)
divide BOTH SIDES by 2 to get rid of that 2 in front
-5=-3x+1
minus BOTH SIDES 1
-6=-3x
divide BOTH SIDES by -3
2=x

-x-7=-12
add7 BOTH SIDES
-x+7-7=-12+7
-x+0=-5
-x=-5

8+11=?

Answers

Nice question! The rule is:

a + b = a(b + 1)

So...

1 + 4 = 1(4 + 1) = 1(5) = 5

2 + 5 = 2(5 + 1) + 2(6) = 12

3 + 6 = 3(6 + 1) = 3(7) = 21

8 + 12 = 8(12 + 1) = 8(13) = 104

The answer is 104.

Please help!!!Given the length of three sides of a triangle, which is a right triangle?
(1) 10,26,24
(2) 20,12,18
(3) 30,15,26
(4) 40,50,80

And also explain why it is the answer.

Answers

Pythagorean Theorem: $a^2 + b^2 = c^2$
c represents the longest side of the triangle
If the triangle is a right triangle, the Pythagorean theorem will be true.

(1) 10,24,26
$10^2 + 24^2 = 676$
$26^2 = 676$
$10^2 + 24^2 = 26^2$
Right Triangle

(2) 12,18,20
$12^2 + 18^2 = 468$
$20^2 = 400$
$12^2 + 18^2 \neq 20^2$
Not a right triangle

(3) 15,26,30
$15^2 + 26^2 = 901$
$30^2 = 900$
$15^2 + 26^2 \neq 30^2$
Not a right triangle

(4) 40,50,80
$40^2 + 50^2 = 4100$
$80^2 = 6400$
$40^2+50^2 \neq 80^2$
Not a right triangle
