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?

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

Nathan bikes every 2 days and swims every 5 days. He started biking on October 2nd and started biking on October 5th. On what day will he bike and swim on the same day. Here are the options for the answers: October 4th, October 8th, October 10th, October 12th, 15th, or 20th.
PLEASE HELP!!
Answer:
October 10, hope this helps.
Step-by-step explanation:
If Nathan started biking on October 2nd, and he started swimming on October 5th, then since October 10 is the closest day to them that he will be swimming and biking, but also because their both even numbers so he will be biking and swimming on October 10th.

what is the value of?
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
Find x
This is a kite from geometry
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

ve, Carpet sells for $36 per square yard. How much will 8 square yards cost?
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.
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
Hope this helps! Good luck.

During a catered lunch, an average of 4 cups of tea are poured per minute. The lunch will last 2 hours. How many gallons of tea should the cateree bring if there are 16 cups in one gallon?
Answer:
30 gallons (that’s a lot of tea!)
Step-by-step explanation:
Hi there!
we know that there are 60 minutes in an hour, 120 in 2 hours.
If 4 cups are poured every minute, we multiply 4 by the number of minutes in 2 hours, 120.
now we have 480 cups. However, they asked for gallons. They already give how many cups are in a gallon, 16, so all we have to do is divide 480 by 16 to find the amount of gallons needed.
480/16 = 30 gallons!
I hope this helped!
Answer:
30 gallon
Step-by-step explanation:
first you count up how many minutes is in 1 hour mutilply it by 2 if 4 cups were poured every minute and there's 16 cups per gallon you take 120 being 2 hours in minutes take 120 multiply it by 4 bc that's how man cups are poured per minute and that 480 cups 480 cups divided my 16 which is how many cups is in a gallon and you get 30

4.5 is 7.5% of what number?
Answer:
60
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.

Do not solve the system below. Its solution is (x, y)
= (1, 1). Instead, answer the questions.
3x + 4y = 7
5x + 10y = 15
If you were going to solve the system above, what
would be the best first step according to the
strategy you just learned?
Solve for x in the first equation.
Solve for y in the first equation.
Solve for x in the second equation.
Solve for y in the second equation.
explain your reasoning .
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.
