Answer:
You have an empty box which is 1,800 grams. After you put the books in, it's 9 kilograms. There are 9,000 grams in 9 kilograms, and 1,800 grams were already there before you put the books.. so just do 9,000 - 1,800 which equals 7,200. Then divide 7,200 by 4, because there are 4 books with equal mass.
Step-by-step explanation:
I divide 7200by 4 and I got 1800

evaluate 2x + 5 - 10 when x = 12
ANSWERS ASAP PLEASE Questions 1-4, WILL GIVE BRAINLIEST
Answer:
1) 23^a+b
2) 5^5
3) 11^x-y
4) 2^10
Step-by-step explanation:
if they have the same base numbers then they are pretty easy to combine. multiplication means you add the exponents, and division means you subtract the exponents. for number 2, you would make them the same base by making 25 -> 5^2 and then just add the exponents.

Ernesto has $70 in a savings account. The interest rate is 5%, compounded annually. To the nearest cent, how much will he have in 3 years?
Answer: $81.03
Step-by-step explanation:
The interest is compounded annually which means that the future value formula applies:
Future value = Amount * ( 1 + rate) ^ number of years
Amount = $70
Rate = 5%
Number of years = 3 years
In 3 years, Ernesto will have:
= 70 * ( 1 + 5%)³
= $81.03

your answer is Option D. ∧ACD≈ ∧BCD because of SAS
Step-by-step explanation:
hope it helps...
The relationships proved to be ΔACD ≈ ΔBCD, because of SAS (Side Angle Side).
What was SAS Theorem?SAS" is when we know two sides and the angle between them. If the two sides of a triangle are equal to the two sides of another triangle, and the angle formed by these sides in the two triangles are equal, then these two triangles are congruent. The SAS Criterion stands for the 'Side-Angle-Side' triangle congruence theorem.
To prove the SAS :-
In ΔACD and ΔBCD
AD=BD (Given)
D=D(Common 90° angle)
CD=CD (Common)
Therefore, ΔACD ≅ ΔBCD, because of SAS (Side Angle Side) rule.

Answer:
x = -4 and x = 5
Step-by-step explanation:
Since [tex]x^2 + 2x[/tex] and [tex]3x + 20[/tex] both equal to y, we know that the expressions equal to each other. We can write a new equation base on that.
[tex]x^2 + 2x = 3x + 20[/tex]
Now we solve the equation.
[tex]x^2 + 2x = 3x + 20[/tex]
[tex]x^2 - x = 20[/tex]
[tex]x^2 - x - 20 = 0[/tex]
[tex](x + 4) (x - 5) = 0[/tex]
[tex]x + 4 = 0 ; x -5 = 0[/tex]
[tex]x = -4 ; x = 5[/tex]

solve the inequality -2(y+4)>16
y < -12
Step-by-step explanation:
Step 1: Simplify both sides of the inequality.
−2y − 8 > 16
Step 2: Add 8 to both sides.
−2y − 8 + 8 > 16 + 8
−2y > 24
Step 3: Divide both sides by -2.
−2y/−2 > 24/−2
y < −12
Answer:
y < −12
Step-by-step explanation:
−2(y + 4) > 16

In basketball there are 3 ways to score: a free throw, worth 1 point, two
pointers, worth 2 points, and a three-pointer, worth 3 points. Let x represent
the number of free throws made, let y represent the number of two pointers
made, and let z represent the number of three pointers made. If a team
scores a total of 100 points, which of the equations below could be used to
determine the number of each type of shot that the team made?
a. x + 3y + 2z = 100
b. 2x + 3y + 3z = 100
c. x + y + z = 100
d. x + 2y + 3z = 100
Answer:
D
Step-by-step explanation:
I think it's D. Because you have that free shots give you 1 point so it is 1x or x , then you have two pointers which give you 2 points so it is 2y and you have three pointers which give you 3 points so it is 3z
