What was the value of x and y for the following equations? Equation 1: 2/3 (x-6) = 6 Equation 2: 2/3y - 6 = 6 x = 15, y = 15 x = 18, y = 15 x = 18, y = 18 x = 15, y = 18
The value of x is 15 and value of y is 18
Solution:
Given equations are:
[tex]\frac{2}{3}(x - 6) = 6\\\\\frac{2}{3}y - 6 = 6[/tex]
From first equation,
[tex]\frac{2}{3}(x - 6) = 6\\\\Remove\ the\ parenthesis\ and\ solve\\\\\frac{2}{3}x - \frac{2}{3} \times 6 = 6\\\\\frac{2}{3}x - 4 = 6\\\\Move\ the\ constant\ from\ left\ side\ to\ right\ side\\\\\frac{2}{3}x = 6 + 4\\\\\frac{2}{3}x= 10\\\\2x = 30\\\\Divide\ both\ sides\ by 2\\\\x = 15[/tex]
From second equation,
[tex]\frac{2}{3}y - 6 = 6\\\\Move\ the\ constant\ from\ left\ side\ to\ right\ side\ of\ equation\\\\\frac{2}{3}y = 6 + 6\\\\\frac{2}{3}y = 12\\\\2y = 36\\\\Divide\ both\ sides\ by\ 2\\\\y = 18[/tex]
Thus value of x is 15 and value of y is 18

Grace starts with 100 milligrams of a radioactive substance. The amount of the
substance decreases by each week for a number of weeks, w. She writes the
expression 100(-)w to find the amount of radioactive substance remaining after w
weeks.
Ryan starts with 1 milligram of a radioactive substance. The amount of the substance
decreases by 40% each week for a number of weeks, w. He writes the expression (1 -
0.4)" to find the amount of radioactive substance remaining after w weeks.
Use the drop-down menus to explain what each part of Grace's and Ryan's
expressions mean.
Answer:
100 is grace's initial amount. w is how much of the substance is being decrased each week. in ryan's equation, 1 is 100% of the substance, so the initial amount, and 0.4 is the amount that is being decreased.
Step-by-step explanation:
Answer:
100= Initial Amount
1/4= decay factor for each week
w= number of weeks
1/4w= decay factor after w weeks
1 - 0.4= decay factor for each week
w= number of weeks
0.4= percent decrease

Aiden borrows a book a public library. He read a few pages on day one. One day two, he reads twice the number of pages than he reads on one day. On the third day, he reads six pages less than what he read on the first day. If he read the entire book that contains 458 pages how many pages did he read on day three
Answer:
110 pages
Step-by-step explanation:
Day 1 =x
Day 2 =2x
Day 3 =x-6
(x)+(2x)+(x-6)=458
Add likes together.
4x-6=458
4x=464. Divide both sides by 4 to get x. X=116
Day 3=116-6=110

Evaluate the expression.
(132−122)÷5
The value of the expression___ is
Final answer:
The value of the expression (132-122)÷5 is 2 after performing the subtraction followed by division.
Explanation:
Evaluating the expression (132−122)÷5 involves two operations: subtraction and division.
First, we subtract 122 from 132, which gives us 10.
Then, we divide the result by 5.
The division of 10 by 5 yields 2.
Therefore, the value of the expression (132−122)÷5 is 2.

Which three length cannot be the length of the sides of a triangle
The missing choices are here
A. 23 m, 17 m, 14 m
B. 11 m, 11 m, 12 m
C. 5 m, 7 m, 8 m
D. 21 m, 6 m, 10 m
Answer:
21 m, 6 m, 10 m cannot be the length of the sides of a triangle ⇒ D
Step-by-step explanation:
There is a fact to form a triangle:
The sum of the lengths of the two smaller sides must be greater than the length of the third side
A.
∵ The smallest sides are 14 m and 17 m
∵ Their sum = 14 + 17 = 31 m
∵ The third side is 23 m
∵ 31 > 23
∴ 23 m, 17 m, 14 m can be the length of the sides of a triangle
B.
∵ The smallest sides are 11 m and 11 m
∵ Their sum = 11 + 11 = 22 m
∵ The third side is 12 m
∵ 22 > 12
∴ 11 m, 11 m, 12 m can be the length of the sides of a triangle
C.
∵ The smallest sides are 5 m and 7 m
∵ Their sum = 5 + 7 = 12 m
∵ The third side is 8 m
∵ 12 > 8
∴ 5 m, 7 m, 8 m can be the length of the sides of a triangle
D.
∵ The smallest sides are 6 m and 10 m
∵ Their sum = 6 + 10 = 16 m
∵ The third side is 21 m
∵ 16 < 21
∴ 21 m, 6 m, 10 m cannot be the length of the sides of a triangle

Which of the following defines liquid measure?
A. The measure of how much space is filled by an object
B. Units used to measure the volume of liquids, such as water, gasoline, and
milk
C. The volume of space inside a container
D. How heavy an object is
Liquid measure refers to the units used for measuring the volume of liquids such as liters, milliliters, etc. It's closely tied to the concept of volume, which is the amount of space that an object, liquid or solid, occupies.
Explanation:Liquid measure is defined as B. Units used to measure the volume of liquids, such as water, gasoline, and milk. This concept is related to the broader idea of volume, which is the measure of the amount of space occupied by an object, regardless of its state of matter. Let's say we want to measure the volume of water we're pouring into a jug. The volume units we would use (liters, milliliters, etc.) are examples of a liquid measure. Similarly, if we are filling a car's gas tank, the liters or gallons dispensed would be a liquid measure too.
Another example is milk that is sold in containers of varying volumes, from small cartons to large gallons. Each of these volumes is a measure of liquid. So, when we talk of liquid measure, we're looking at how much space a certain quantity of liquid occupies which is generally determined in liters, milliliters or sometimes cubic meter (m³).

Which inequality is equivalent to -m> 15
This inequality can be simplified.
~Divide -1 to both sides (flip the symbol since we're dividing a negative number)
-m/-1 < 15/-1
m < -15
Best of Luck!
Answer:
m < -15
Step-by-step explanation:
Step 1: Multiply both sides by -1
-m > 15
-m * -1 > 15 * -1
Since you multiply by a negative, you must flip the sign
-m * -1 > 15 * -1
m < -15
Answer: m < -15

Determine the center and radius of the following circle equation:
22 + y2 – 10x + 18y + 42 = 0
Answer:
C(5,-9) and r=8.
Step-by-step explanation:
C(p, q) - center
r=radius
k:x^2 +y^2 +dx+ey+f=0
x^2+y^2 - 10x+18y+42=0
d=-10, e=18, f=42
p=-d/2=-(-10)/2=10/2=5
q=-e/2=-18/2=-9
r^2 =p^2+q^2-f
r^2 =5^2 +(-9)^2 - 42
r^2=25+81-42
r^2 =106-42
r^2 =64
r=sqrt(64)
r=8
C(p,q)=C(5,-9) r=8

Six times it took 4 flips of the coin to land tails up.
Twice it took 4 flips of the coin to land tails up.
It took 6 flips of the coin to land tails up more often than any other number of flips.
The greatest number of flips it took to land tails up was 6.
Answer:
The dot plot of flip times increased gradually between 1, 2 and 3. The dot plot grew sharply from 3 to 4 and then 6.
Step-by-step explanation:
There are only 5 probabilities. It took Martin 1,2,3,4 and 6 flips to land a tail up. That 1,2,3 times of flips to land a tail up happened once. 4 times of flips to land a tail up happened 8 times. The greatest number of flips took to land tails up was 6 but the question didn't give details how many times it happens.

Complete the table below
Answer:
10 100 1,000
30 60 1,800
40 40 1,600
Step-by-step explanation:
First you take each width and multiply it by 2 to get both widths.
Then you take 120 and subtract each width from it because it's 120 feet for the entire fence.
Next you end up with the length.
Finally you multiply the length by the width to get the area.
