Answer:
m = 6
Step-by-step explanation:
First, add like terms:
2m + 7m + 3m = 72
12m = 72
Divide each side by 12:
m = 6
So, the answer is m = 6
Answer:
m = 6
Step-by-step explanation:
2 m + 7 m + 3 m = 72
12 m = 72
[tex] \sf \small\: m \: = \frac{72}{12} \\ [/tex]
m = 6
Hence, your answer is 6.

Explanation:
Locate the point that has x = -3 as its x coordinate. The y coordinate is the output of the function when we use this x value. So the point (-3,-7) means that f(-3) = -7. As another example, f(2) = 3.

Answer:
140°
Step-by-step explanation:
Angles 1 and 3 are "corresponding" angles, so are congruent.
∠1 = ∠3
20x +60 = 30x +20
40 = 10x . . . . . . . . . . . . subtract 20x+20
4 = x . . . . . . . . . . . . . . divide by 10
∠1 = 20x +60 = 20(4) +60 = 80 +60
∠1 = 140°
Answer:
140°
Step-by-step explanation:
Angle 1 and angle 3 are corresponding angles ;
Corresponding angles are equal ;
Hence,
Angle 1 = Angle 3
20x + 60 = 30x + 20
Collect like terms
20x - 30x = 20 - 60
-10x = - 40
x = 4
Angle 1 is thus :
20x + 60 ; x = 4
20(4) + 60
80 + 60
= 140°

The dimensions (width and length) of room1 have been read into two variables : width1 and length1 . The dimensions of room2 have been read into two other variables : width2 and length2 . Write a single expression whose value is the total area of the two rooms. (width1length1) (width2length2)
Answer:
Total area of the two rooms = (width1length1) + (width2length2)
Step-by-step explanation:
The area of the rectangular shape is given by = Length * breadth
Therefore the area of the two rooms can be calculated using the above formula when the variables lengths and widths are given.
Area 1= Area of the first room = length * breadth= (width1length1)
Area 2=Area of the second room = length * breadth= (width2length2)
Total area of the two rooms = Area1 + Area 2
= (width1length1) + (width2length2)

A gene for sweat gland production is found on the X chromosome. If a man who lacks sweat glands marries a woman who has normal sweat glands, what will be the phenotype of their children?A. All of the boys will lack sweat glands.B. All of the girls will lack sweat glands.C. The girls will have sweat glands in some areas, but lack sweat glands in others.D. All of the boys will have sweat glands.E. All the boys will have sweat glands, and the girls will have sweat glands in some areas but not others.
Answer:
Option D, All of the boys will have sweat glands
Step-by-step explanation:
Given -
Gene for sweat gland production is found on the X chromosome
Genotype of man - lacks sweat glands (XY)
Genotype of women - has normal sweat glands (X'X')
X' - sweat glands
X - no sweat glands
This is an X linked recessive trait
If these two mates, then the all males will have sweat glands
X'X' * XY ---> X'X, X'X, X'Y, X'Y
Option D, All of the boys will have sweat glands

Explanation:
f(x) is the outer function, so the final output -8 corresponds to f(x)
We see that f(-4) = -8 in the first column of the table. I'm starting with the output and working my way backward to get the input. So we started with -8 and worked back to -4.
Then we move to the g(x) function to follow the same pattern: start with the output and move to the input. We start at -4 in the g(x) bubble and move to 3 in the x bubble.
In short, g(3) = -4
So,
f(g(x)) = f(g(3)) = f(-4) = -8
We see that x = 3 leads to f(g(x)) = -8
Find out what t means please

Answer:
Part A is 34
Part B is 2
Step-by-step explanation:
This question did provide some clues to answer this question. Every week, the area covered by the algae is multiplied by 2^1.
To find the area cover increase by the algae per day, the exponent should be divided by 7 since there are 7 days in a week. Hence, every day, the area covered by the algae multiplies by 2^(1/7). In other words, 1 day after the algae was spotted, the area is 12.5 * 2^(1/7), which answers part B.
10 days after the algae was spotted, the area covered by the algae is 12.5 * 2^[(1/7)*10] = 33.6475... , which rounds up to 34 and answers part A.

Plsss help no one answered the other times I put this question
Answer:
a) The equation (10s + 8w) represents the calories Bridget ate on Monday and the equation (20s + w) represents the calories she ate the next day.
b) The number of calories in each strawberry is 4 and the number of calories in each vanilla wafer cookie is 19. The solution is s= 4 and w = 19.
Step-by-step explanation:
For part A, Bridget ate 10 strawberries and 8 vanilla wafer cookies on Monday. Since the the number of calories in a strawberry is s and the number of calories in a vanilla wafer cookie is w , the number of calories Bridget ate on Monday is 10s + 8w. The next day, Bridget ate 20 strawberries and 1 vanilla wafer cookie. Hence, the number of calories Bridget ate on the next day is 20s + w.
For part B,
we will create two different simultaneous equations.
Equation 1: 10s + 8w = 192
Equation 2: 20s + w = 99
We need to find one of the terms first to solve the other term. For this case, I will solve for w first.
Multiply the first equation by 2.
Equation 3: 20s + 16w = 192*2 = 384.
Now, subtract equation 2 from this new equation.
Equation 4:
(20s + 16w) - (20s + w) = 384 - 99
20s + 16w - 20s - w = 285
15w = 285
This leaves only w left and we can solve w.
w = 285 / 15 = 19
Now, we can solve for s using equation 2.
20s + 19 = 99
20s = 99-19 = 80
Hence,
s = 80/20 = 4

is this table proportional or non-proportional?
Answer:
Proportional
Step-by-step explanation:
Proportional functions can be written as [tex]y=kx[/tex], where [tex]k[/tex] is some constant of proportionality. Plugging in (x,y) pair into this function will yield a constant of proportionally of [tex]k=\frac{3}{2}[/tex] and since this constant is maintained through all the coordinate pairs in the table, the table is proportional.
Deondra has $420 to spend at a bicycle store for some new gear and biking
outfits. Assume all prices listed include tax.
• She buys a new bicycle for $236.31.
She buys 2 bicycle reflectors for $3.07 each and a pair of bike gloves for
$34.75.
• She plans to spend some or all of the money she has left to buy new biking
outfits for $59.50 each.
Write and solve an inequality which can be used to determine o, the number
of outfits Deondra can purchase while staying within her budget.
Answer:
Deondra can buy 2 outfits.
Step-by-step explanation:
Since Deondra has $ 420 to spend at a bicycle store for some new gear and biking outfits, and she buys a new bicycle for $ 236.31, 2 bicycle reflectors for $ 3.07 each and a pair of bike gloves for $ 34.75, and she plans to spend some or all of the money she has left to buy new biking outfits for $ 59.50 each, to determine the number of outfits Deondra can purchase while staying within her budget the following calculation must be performed:
(420 - (236.31 + 2 x 3.07 + 34.75)) / 59.5 = X
(420 - (236.31 + 6.14 + 34.75)) / 59.5 = X
(420 - 277.2) / 59.5 = X
142.8 / 59.5 = X
2.4 = X
Therefore, Deondra can buy 2 outfits.
