What is (5•3) - 18 and can u explain y
Answer:
-3
Step-by-step explanation:
You would find what the answer to (5•3) is then subtract that answer with 18. So it would be 15-18=-3
Answer:
The answer is -3
Step-by-step explanation:
The answer is -3 because of the order of operations PEMDAS (parenthesis, exponent, multiplication/division, addition/subtraction)
Therefore, you would multiply the two numbers inside the parenthesis first, which would give you 15-18, and from there you can subtract 18 from 15 which would give you -3.
Find the ordered pairs for the x- and y-intercepts of the equation 5x-6y=30 and select the appropriate option below
Answer:
Y=-5
X=6
Step-by-step explanation:
set x =0 then solve then set y=o and solve
Answer:
5x - 6y = 30
6y = 5x - 30
Y = 5/6x - 5
y intercept = -5
Therefore (0, -5)
0 = 5/6x - 5
5/6x = 5
x = 6
x intercept = 6
therefore (6,0)
answer : The x-intercept is (6, 0), the y-intercept is (0, –5).
x intercept =

Seven more than twice a number is equal to 21. Find all the numbers that make this sentence is true.
x = a number
7 + 2x = 21
Subtract 7 from both sides
2x = 14
Divide both sides by 2
x = 7
7 is the only number that makes this sentence true.

In each expression below, identify the coefficient, constant, and variable. a. 7 + 9 b. 6 – 5 c. 4.5 – 2.7
The variable is the letter like x or y. The coefficient is the number next to the variable like the 2 in 2x or if its just x it would be 1. The constant is the number by itself usually at the end.
Example 2x+5
Variable is x constant is 5 and coefficient is 2. Sorry i didn't answer the actual question and just told you how to find it but those expressions don't have any of these things.

The maximum weight your office building's elevator can carry is 1,500 pounds. You
need to move boxes each weighing 50 pounds from the fifth floor to the third
floor. Let n represent the number of boxes you place in the elevator. If you weigh
140 pounds, what is the correct inequality that can be used to determine the
maximum number of boxes that you can place in the elevator at one time? Assume
only you and the boxes are in the elevator.

1. Solve using any method:
2x – 3y = -2
4x + y = 24
Answer:
[tex]x=5,y=4[/tex]
Step-by-step explanation:
[tex]2x-3y=-2[/tex]
Add 3y to both sides:
[tex]2x-3y+3y=-2+3y[/tex]
[tex]2x=-2+3y[/tex]
Divide both sides by 2:
[tex]\frac{2x}{2}=-\frac{2+3y}{2}[/tex]
[tex]x=\frac{-2+3y}{2}[/tex]
Substitute this into the second equation:
[tex]4* \frac{-2+3y}{2}+y=24[/tex]
[tex]2\left(3y-2\right)+y=24[/tex]
[tex]7y-4=24[/tex]
Add 4 to both sides:
[tex]7y-4+4=24+4[/tex]
[tex]7y=28[/tex]
Divide both sides by 7:
[tex]\frac{7y}{7}=\frac{28}{7}[/tex]
[tex]y=4[/tex]
We know that [tex]x=\frac{-2+3y}{2}[/tex]
Thus, [tex]x=\frac{-2+3* \:4}{2}[/tex]
[tex]x=\frac{10}{2}[/tex]
[tex]x=5[/tex]
Answer:

Find the midpoint and the distance between these 2 points. (-4,8) and (6,-2)
Answer:
Midpoint = (1,3)
Distance = 10√2
Step-by-step explanation:
Midpoint
[tex]Midpoint = \left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)\\\\\left(x_1,\:y_1\right)=\left(-4,\:8\right),\:\left(x_2,\:y_2\right)=\left(6,\:-2\right)\\\\=\left(\frac{6-4}{2},\:\frac{-2+8}{2}\right)\\\\=(\frac{2}{2} , \frac{6}{2} )\\\\Simplify\\=\left(1,\:3\right)[/tex]
Distance
[tex]Distance = \sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}\\\\(-4,8)=(x_1,y_1)\\(6,-2)=(x_2,y_2)\\\\d=\sqrt{\left(6-\left(-4\right)\right)^2+\left(-2-8\right)^2}\\\\d = \sqrt{(6+4)^2+(-2-8)^2}\\ \\d = \sqrt{(10)^2 +(-10)^2}\\ \\d = \sqrt{100+100} \\\\d = \sqrt{200}\\ \\d = 10\sqrt{2}[/tex]
A student was performing an experiment that compared a new protein food to the old food for goldfish. He found the mean weight gain for the new food to be 12.8 grams with a standard deviation of 3.5 grams. Later he realized that the scale was out of calibration by 1.5 grams (meaning that the scale weighted items 1.5 grams too much). What should the mean and standard deviation be for the new food
Answer:
Mean = 11.3 grams
Standard Deviation = 3.5 grams
Step-by-step explanation:
Mean is affected by change of origin but standard deviation is not affected. Hence the scale weighed items 1.5 grams affect only the mean not standard deviation. Hence, the mean for new food item is 12.8 - 1.5 = 11.3 grams as weight gain by 1.5 gram due to wrong calibration and the standard deviation remains the same as 3.5 grams.

Find the cost function for the marginal cost function. C(x) =0.06 e 0.08x; fixed cost is $10 C(x)=_______
Answer:
The cost function for [tex]C(x) = 0.06\cdot e^{0.08\cdot x}[/tex] is [tex]c(x) = 0.75\cdot e^{0.08\cdot x}+10[/tex].
Step-by-step explanation:
The marginal cost function ([tex]C(x)[/tex]) is the derivative of the cost function ([tex]c(x)[/tex]), then, we should integrate the marginal cost function to find the resulting expression. That is:
[tex]c(x) = \int {C(x)} \, dx + C_{f}[/tex]
Where:
[tex]C_{f}[/tex] - Fixed costs, measured in US dollars.
If we know that [tex]C(x) = 0.06\cdot e^{0.08\cdot x}[/tex] and [tex]C_{f} = \$\,10[/tex], then:
[tex]c(x) = 0.06\int {e^{0.08\cdot x}} \, dx + 10[/tex]
[tex]c(x) = 0.75\cdot e^{0.08\cdot x}+10[/tex]
The cost function for [tex]C(x) = 0.06\cdot e^{0.08\cdot x}[/tex] is [tex]c(x) = 0.75\cdot e^{0.08\cdot x}+10[/tex].

A problem states: "There are 5 more girls than boys at the party. There are 27 children at the party in all. How many boys are there at the party?"
Let b represent the number of boys.
Which expression represents the number of girls?
5−b
b + 5
b⋅5
b−5
Answer:
b + 5
Step-by-step explanation:
If there are 5 more girls and b represents boys, then adding 5 to b (boys) gives you the number of girls. Hope this helps!
Answer:
The second one
Step-by-step explanation: 27-5=22 then u divide 22 divided by 2 and you get 11 then you add five girls to the 11 and you get 16 so there's 11 boys and 16 girls at the party which makes the equation 11+5=16 so the answer is number b (the second one).
