If you buy 2 pens you get a 50% discount on the second pen. If I pen cost 2.30 how much will 2 pens cost you. (NEED equation and work!!)

Answers

Answer:

Two pens will cost you $3.35

Step-by-step explanation:

2.30*.5=1.15

2.30+1.15=3.35

subtract (3x+5)-(x+2).

Answers

2x+3

First, subtract “x” from “3x” to get 2x. Then, subtract 5-2. You should end up with an answer of 2x+3!

Expression: (3x + 5) - (x + 2)
= (3x + 5) - 1 (x + 2) *we will be distributing -1 to x and 2.
= 3x + 5 - x - 2
= 3x - x + 5 - 2 (we have combined like terms)
= 2x + 3

So, in conclusion, the answer and expression for this problem is: 2x + 3.

Answers

Answer:

70 degrees

Step-by-step explanation:

Since the angles of a triangle have to add up to 180 degrees, you know that the third angle of the triangle on the left would be 180 - 60 - 65 = 55 degrees. Then, since the angles on a straight line have to add up to 180 degrees you could find one of the two missing angles of the second triangle by doing

180 - 55 - 50 = 75.

Then, you have 2 out of the 3 angles of the triangle on the right and you can find the third, the ?, by doing 180 - 75 - 35 = 70 degrees

Andre's school orders some new supplies for the chemistry lab. The online store shows a pack of 10 test tubes costs $4 less than a set of nested beakers. In order to fully equip the lab, the school orders 12 sets of beakers and 8 packs of test tubes.

1. Since t is in terms of b from the first equation, this expression can be substituted into the second equation where t appears. Write and equation that shows this substitution.

2.solve the equation for b

3.How much did the school pay for a set of beakers? For a pack of text tubes?

Answers

Answer:

x=6

Step-by-step explanation:

Solve for x.

5x-15 = 2x+3

(Move the 2x to the other side of the equation.)

3x-15= 3

(Move the 15 to the right side of the equation.)

3x=18

(Divide both sides by 3 to isolate the variable.)

x=6

Solve for x in the first equation.
Solve for y in the first equation.
Solve for x in the second equation.

Answers

Answer:

(x,y) = (1,1)

Answer:

The answer is C

and the second answer is

Solving for x in the second equation produces a coefficient of 1 or –1. This choice avoids fractions. Each term in the second equation can be divided by 5. That makes x easy to isolate.

Answers

Answer:

1) 80

2) 58

Step-by-step explanation:

180 - 112 = 68

180 - 68 + 32 = angle 2

180 - (63 + 59) = angle 1

Answer: The first one is 80, the second one is 58

Step-by-step explanation: a triangle adds up to 180. For the first one, you first find the degree for the last corner (the one that is not marked). Than angle would be 64, a straight line is 180 degrees, subtract that by 112 to get 64. Then you add this angle with 32, getting 100. Then subtract that by 180 and you'll get 80 as the answer. For the second one, just add the two numbers up and subtract that by 180.

ve, Carpet sells for $36 per square yard. How much will 8 square yards cost?

Answers

Answer:

$288

Step-by-step explanation:

If each square yard of carpet is $36, you just have to multiply 8 by that to get the total.

$288.00

Because each square yard = $36 all you do is add $36, 8 times. But the easiest way to do it would be to simply times 36 by 8:

36 x 8 =288

So your answer is,

$288.00

4.5 is 7.5% of what number?

Answers

Answer:

Step-by-step explanation:

The required number is 60.

What is percent?

In mathematics, a percent is a number or ratio expressed as a fraction of 100. It is often denoted using percentage sign "%".

Now the given expression is,

4.5 is 7.5%

Let x be the number.

Therefore, 7.5% of x is 4.5

⇒ 7.5% of x = 4.5

⇒ 7.5% * x = 4.5

⇒ 7.5/100* x = 4.5

⇒0.075 x = 4.5

Dividing both side by 0.075 we get,

x = 4.5 / 0.075

Solving we get,

x = 60

this is the required number.

Thus,the required number is 60.

Answer:

15x^2-14x-4

Step-by-step explanation:

(8x^2 * x-7x+2)+(7x^2 -7x-6)

you take out the parentheses

you add the common ones so -7x+-7x= -14x

8x^2 +7x^2 = 15x^2

and 2-6= -4

so in total it's 15x^2-14x-4

Answer: 11x^2 -16x-3

Step-by-step explanation:

Solution:

Your problem → (8x^2-7x+2) + (3x^2-9x-5)

(8x2-7x+2)+(3x2-9x-5)

=8x2-7x+2+3x2-9x-5

=8x2+3x2-7x-9x+2-5

=11x2-16x-3
