if 4r+3trs-3u+2=12s+r-1, then t =
Answers
The solution of the expression for the value of t will be t = ( 12s -3r +31) / 3rs.
What is an expression?Numeral variables and operations marked by the signs for addition, subtraction, multiplication, and division are combined in the mathematical equation.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented using mathematical symbols. They can also signify other characteristics of logical grammar, such as the operation order.
Given expression is 4r+3trs-3u+2=12s+r-1. the value of t for the expression will be solved as:-
4r+3trs-3u+2=12s+r-1,
3trs = 12s - 4r +r + 34 -2 - 1
3trs = 12s - 3r + 31
t = ( 12s -3r +31) / 3rs
Therefore, the solution of the expression for the value of t will be t = ( 12s -3r +31) / 3rs.

Name a combination of coins that is 130% of the value of a dollar.
Answers
Answer:
5 quarters, 1 nickel
Step-by-step explanation:
A combination of coins which is equivalent to 130% of a dollar is equal to 8 quarters,2 dimes and 2 nickels.
What are percentages?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”
Given: A dollar and to find its 130% equivalent in the form of coins.
A nickel is worth 5 cents
A dime is worth 10 cents
A quarter is worth 25 cents
Now a dollar is equivalent to 100 cents
Thus 130% of a dollar is equivalent to
130/100 ×100 +100 =230 cents
Therefore a combination of 8 quarters which is equal to 200 cents and 2 dimes and 2 nickel is equal to 230 cents as
8×25+2×10+2×5=230 cents.
Hence, A combination of coins which is equivalent to 130% of a dollar is equal to 8 quarters,2 dimes and 2 nickels.

Evaluate xy for x = –9 and y = 5.
A –4
B 45
C –45
D –14
Answers
Answer:
C
Step-by-step explanation:
9 times 5 is 45. when ur multiplying and there's only one negative sign, the answer will always be negative.
These types of problems can be fairly simply once you understand substitution. Substitution is when we put in values (in this case -9 and 5) in their set variable (x and y in this case.)
The problem states that x=-9 therefore we put in -9 for x in the multiplication of xy so it looks like this: (-9)(y). Next we want to substitute in the y value which is 5 so that we now have (-9)(5).
Because there is no plus or minus sign, along with a division sign, we then MULTIPLY these two numbers because the variables are connected so -9*5 would equal to -45.

Answers
Answer: 40 feet, 60 feet, and 70 feet.
The lengths of the sides of a triangle can be 40 feet, 60 feet, 70 feet.
What is Triangle Inequality?According to the Triangle Inequality Theorem, any two triangle sides must add up to more than the third side's length.
Given:
As, the sum of two sides of the Triangle is greater than third side.
1. 25 feet, 30 feet, 60 feet
Then, 25+ 30 <60
2. 40 feet, 60 feet, 70 feet
40+ 60 > 70
60+ 70>40
70+ 40 > 60
3. 40 feet, 175 feet, 220 feet
40+ 175 < 220
4. 80 feet, 150 feet, 230 feet
80+ 150 = 230
Hence, the lengths of the sides of a triangle can be 40 feet, 60 feet, 70 feet.

Now,
1/2 per 3/4 hour = (4/3)(1/2) = 2/3 per hour
1/2 per 5/4 hour = (4/5)(1/2) = 2/5 per hour
2/3 - 2/5 = 10/15 - 6/15 = 4/15

NO SAMPLE RESPONSES FROM ED PLEASE

Answer:
The total variation in water level is -3.3
Step-by-step explanation:
Round 1.05 mm to the nearest whole number the result is -1.1 then round 2.48 which the result will be equal to 3. The total variation in water level is -3.3
The total variation in water level is -2.6.
We have,
Matea recorded that water levels in one part of the river fell 1.05 millimeters per year for 2.48 years.
The decrease of the rate -1.05 mm/year can be rounded to -1.
Since -1.05 is negative and rounded to a greater value, the estimate could be adjusted to a slightly lesser value, maybe -2.5 or -2.6.
Thus, the total variation in water level is -2.6.
