pamelia is 9 years younger than jiri. The sum of their ages is 55. What is Jiris age?
Answers
Answer: 32
Step-by-step explanation: since Jiri is 9 years older, you set an equation where x (Pamelia age) + 9. So the equation is 55= x + (x+9). You subtract 9 from both sides, then divide 46 by 2 to find the Pamelia age. To find Jiri’s age, add 9 to 23 (Pamelia age).

What is the solution to the inequality 1 2/3 > r - 7/12
Answers
Answer:
r ≤ 2 1/4
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Equality Properties
Rewriting Fractions
Step-by-step explanation:
Step 1: Define
1 2/3 ≥ r - 7/12
Step 2: Solve for r
Rewrite: 5/3 ≥ r - 7/12
Isolate r: 9/4 ≥ r
Rewrite: r ≤ 9/4
Reduce: r ≤ 2 1/4
Here we see that any number r less than or equal to 2 1/4 will work as a solution to the inequality.

Step-by-step explanation:
1+1=2 is clearly true.
2+3=4 is clearly false.
x if and only if y has a value of true if x and y are both true or both false. It is false otherwise.
So, true if and only if false has a value of false, so the answer is [tex]\boxed{false}[/tex]
The sum of two numbers is 26. The first number is two more than 5 times the second number. What are
the two numbers? Define your variables. Write two equations and then solve. Be sure to write your
answer in a complete sentence!
Answers
Answer:
Let us assume the two numbers be x and y
From the above condition we can write, x + y = 26 equation 1
second condition first no x = 2 more 5 times of the second no. that is 5y + 2
then we can write, x = 5y + 2..... eqation (2)
from equation 1 x + y = 26
subtracting y from each side , x+ y - y = 26 - y
x = 26 - y
plugging this value of x in eqn. no (2 ) we get,
26-y = 5y + 2
subtracting 5y on both sides,
26 - y - 5y = 5y - 5y + 2
26 - 6y = 2
subtracting 26 from both sides,
26 -26 -6y = 2- 26
-6y = -24
eliminating minus sign from both sides,
6y = 24
dividing by 6 on both sides,
y = 24/6 = 4
substituting this value of y in equation 1 we get,
x + 4 = 26
subtracting 4 from both sides,
x = 26- 4 = 22
Step-by-step explanation:
so we solve the 2 eqns we get x = 22 and y = 4
the two numbers will be 22 and 4

Answer:
y=-3x+1
Step-by-step explanation:
1) the slope-interception form is: y=slope*x+intercept;
2) if A(0;1) and B(2;-5) then it is possible to make up the equation of the required line:
[tex]\frac{x-X_A}{X_B-X_A} =\frac{y-Y_A}{Y_B-Y_A}; \ => \ \frac{x}{2}=\frac{y-1}{-6};[/tex]
3) the equation in the item 2 can be written in slope-interception form:
x=(y-1)/(-3); ⇔ y-1= -3x; ⇔ y= -3x+1.
P.S. note, the suggested way of solution is not the shortest one.

HELP ASAP PLEASE 100 POINTS GIVEN!!!!!!!!
Smith was the top scorer in a women's professional basketball league for the 2006 regular season, with a total of 850 points. The number of two-point field goals that Lindsey made was 57 less than double the number of three-point field goals she made. The number of free throws (each worth one point) she made was 41 less than the number of two-point field goals she made. Find how many free throws, two-point field goals, and three-point field goals Lindsey Smith made during the 2006 regular season.
Answers
Given that :
Total point = 867
Let :
number of 3 point goals = p
Number of 2 point goals = 2p - 66
Number of 1 point goals = (2p - 66) - 36 = 2p - 102
Hence,
3p + 2(2p - 66) + 2p - 102 = 867
3p + 4p - 132 + 2p - 102 = 867
3p + 4p + 2p - 234 = 867
9p - 234 = 867
9p = 867 + 234
9p = 1101
p = 122.33
2 pointer = 2p - 66
2(122.33) - 66 = 178.67
1 point = 2p - 102
2(122.33) - 102
= 142.67
Given that :
Total point = 867
Let :
number of 3 point goals = p
Number of 2 point goals = 2p - 66
Number of 1 point goals = (2p - 66) - 36 = 2p - 102
Hence,
3p + 2(2p - 66) + 2p - 102 = 867
3p + 4p - 132 + 2p - 102 = 867
3p + 4p + 2p - 234 = 867
9p - 234 = 867
9p = 867 + 234
9p = 1101
p = 122.33
2 pointer = 2p - 66
2(122.33) - 66 = 178.67
1 point = 2p - 102
2(122.33) - 102
= 142.67
