Tim's weight is 280 pounds.
What is Tim's weight?Let t, j and r represent Tim's, Jim's and George's weight respectively.
The following equations can be determined giving the information in the question:
t = 2j equation 1
j = g - 50 equation 2
r = 10 + g equation 3
r = 200
Substitute for r in equation 3 : 200 = 10 + g
g = 200 - 10
g = 190
Substitute for g in equation 2 : j = 190 - 50 = 140
Substitute for g in equation 3: t = 2(140)

sketch the graphs 3y+2x=1
Answer: y= -2/3 x + 1/3
Step-by-step explanation:
The first thing you need to do is but it into standard y = mx + b form, where m is the slope of the line and b is the y-intercept. Using algebra, we can turn 3y + 2x = 1 into y = -2/3x + 1/3. the slope is -2/3 which means you start at the y-intercept (0,1/3) and go down 2 and to the right 3. Putting it on paper or in a graphing simulator will give you this line. The point on the y-axis is the y-intercept and the point on the x-axis is the x-intercept.
Answer:
make 3y subjet of the fomulae then subtract 2x then divide by 3 both sides then the ans will be y= -2x+1/3

4 lemons per pitcher basically by looking at the graph you can determine each pitcher increased by a steady pattern of 4 lemons per pitcher.
Example: 2x=8, x=4, 2(4)=8, 8=8 true, the x and y value is cannot be 0 for this equation since no workers means no lemons. If I subtract back by -4 the graph would look like: 1 4, 0 0. Proving this. Also another example I can do is 3x=12, divide 3 by both side x=4, plug them in, 12=12 which is true. Keep in mind X means Pitcher so 4 is correct.
Oh yea less compilcated way is to just look a graph I did all those step to prove to you. Good luck!

What is the slope of a line that is parallel to –x + 3y = 6 Responses 1/3 StartFragment, 1/3, -1 StartFragment, -1, 3 StartFragment, 3, 6
The slope of the line parallel to the line –x + 3y = 6 is a 1/3 option (A) 1/3 is correct.
What is the slope?The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
It is given that:
The equation of the line:
–x + 3y = 6
Write the equation in standard form:
y = x/3 + 6/3
y = x/3 + 2
m = 1/3
The slope of the line parallel to the line –x + 3y = 6
M = 1/3
Thus, the slope of the line parallel to the line –x + 3y = 6 is a 1/3 option (A) 1/3 is correct.

a bag contains 2 green, 4 blue, and 3 yellow disks. alana selects 4 disks from the bag at random, one at a time, without replacing them. what is the probability that she selects all 4 blue disks?
The probability that she selects all 4 blue disks is 0.0317.
What is probability?The probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
Now, according to the question;
There is a total of 2 green disks.
There is a total of 4 blue disks.
There is a total of 3 yellow disks.
The formula for selecting the combination of 4 blue disks are
Probability = (combination for 4 blue)/ Total combination for 9.
The combination is given by the relation;
ⁿCₓ = n!/{x!(n-x)!}
The combination for getting 4 blues is-
n is the total blue disks = 9
x is the selected blue disks = 4
⁹C₄ = 9!/{4!(9-4)!} = 126
The required probability = 4/126

m< 1=3x° and m2 = (x+48)°
If the two angles are supplementary then the value of x is 33°.
Two angles that sum to a straight angle or 180° are called supplementary angles.
The non-shared sides of two supplementary angles that are nearby create a straight line if they share just one side and have a common vertex. A linear pair of angles is the name given to such angles. However, extra angles might be spaced apart and need not be on the same line. For instance, opposite angles of a cyclic quadrilateral (one whose vertices all fall on a single circle) and adjacent angles of a parallelogram are supplementary.If the two given angles are supplementary then we can create a linear equation in x of the form:
m∠1+m∠2=180°
Substituting the values we get:
3x°+(x+48)°=180°
or, 4x°+48°=180°
or, 4x°=180°-48°
or,4x°=132°
or, x°=33°
Hence the value of x is 33°.

if x=-5,0,4,8,13 and y=-7,3,11,19,29 what is the slope of the line
The slope of the line is 1/2.
What is slope?The slope is a measure of the steepness of a line, or a section of a line, connecting two points.
Slope tells you how steep a line is, or how much y increases as x increases. The slope is constant (the same) anywhere on the line.
For example, for the equation y = 3x – 7, the slope is 3, and the y-intercept is (0, −7).
Given:
x=-5,0,4,8,13 and y=-7,3,11,19,29

The tree will be feet tall in the mural.
Answer:
F=10, S=26
Step-by-step explanation:
We know that the base is 24. Using that information, 10^2+24^2=26^2 which is a pythagorean triple
The height of the tree in the mural should be 22.5 feet.To determine the height of the tree in the mural, we can set up a proportion using the given information:
Devon's height in the mural: 4.5 feet
Devon's actual height: 6 feet
Tree's height in the mural: Unknown (let's denote it as x)
Tree's actual height: 30 feet
The proportion can be set up as follows:
(Devon's height in the mural) / (Devon's actual height) = (Tree's height in the mural) / (Tree's actual height)
(4.5 feet) / (6 feet) = x / (30 feet)
Now, let's solve for x by cross-multiplying:
4.5 feet * 30 feet = 6 feet * x
135 feet = 6x
Now, divide both sides of the equation by 6 to find x:
x = 135 feet / 6
x = 22.5 feet
So, the height of the tree in the mural should be 22.5 feet.

OA. Significantly low, because it is more than two standard deviations below the mean
OB. Neither, because it is within two standard deviations of the mean
OC. Significantly high, because it is more than two standard deviations above the mean
OD. It is impossible to determine with the information given
B. Neither, because it is within two standard deviations of the mean.
Given; A certain group of test subjects had pulse rates with a mean of 78.9 beats per minutes.
Standard deviation of 11.7 beats per minute.
Range Rule of Thumb:
Standard deviation = Range/4.
Range = 4×SD.
= 4×11.7
= 46.8
The "usual" range for this situation is,
78.9-2(11.7) to 78.9+2(11.7) = 55.5 to 102.3
Significantly low will be less than 55.5
Sig high will be greater than 102.3
Pulse rate - Mean = 92.3 - 78.9 = 13.4
This value below mean
Then check 2×Standard deviation = 2×11.7= 23.4
This value is also below the mean value.
Significantly low values are 55.5 beats per minute or lower.
Significantly high values are 102.3 beats per minute or higher.
Hence it is within two standard deviations of the mean.
Therefore, the answer is B Neither, because it is within two standard deviations of the mean.
