Answer: Let the 2 numbers be x and
sum of two numbers is 28....Eq 1: x + y = 28
sum of 6 times the 1st number and 3 times the 2nd number is 105....Eq 2: 6x + 3y = 105
Rearrange Eq 1 to solve for x.
x + y = 28
x = 28 - y --> Substitute into Eq 2, you get
6(28 - y) + 3y = 105
168 - 6y + 3y = 105
-3y = -63
y = -63 / -3 = 21
Now solve for x using Eq 1.
x = 28 - y = 28 - 21 = 7
hope it helped
Step-by-step explanation:
The number of termites in a nest in any given month can be represented by the
function f(t) = 4(3)^t where t represents the number of months.
The number of ants in a box can be represented by the function represented by the
table:
Months
0-1-2-3-4
Number 20-45-101-228-513
What is the positive difference in the number of termites and the number of ants in
the fourth year?
im pretty sure the answer is 189
The positive difference in the number of termites and the number of ants in the fourth month will be 189. Option B is correct.
What is the application of subtraction?In mathematics, subtraction is defined as the difference between two quantities. The application of subtraction can be used broadly in different applications to find or solve the problems such as finding differences between two quantities and many more.
It is given that, the number of termites in a nest in any given month can be represented by the function [tex]\rm f(t) = 4(3)^t[/tex].
For the fourth month,
f(4) = 4(3)⁴
f(4) = 324
From the table, it is observed that the number of ants in four months is 513.
The positive difference in the number of termites and the number of ants in the fourth month is found as,
=513-324
=189
Thus, the positive difference in the number of termites and the number of ants in the fourth will be 189. Option B is correct.

Answer:
y = 6
Step-by-step explanation:
[tex]3(y - 5) + 2 = 5 \\ 3y - 15 + 2 = 5 \\ 3y - 13 = 5 \\ 3y = 5 + 13 \\ 3y = 18 \\ \\ y = \frac{18}{3} \\ \\ y = 6[/tex]
I hope I helped you^_^
The solution of the equation 3(y - 5) + 2 = 5 gives the result y = 6.
Thus, option (d) is correct.
An equation is a mathematical statement that shows that two expressions are equal. It consists of two sides separated by an equal sign (=).
Let's solve the equation step by step:
3(y - 5) + 2 = 5
First, distribute the 3 on the left side:
3y - 15 + 2 = 5
Combine the constants on the left side:
3y - 13 = 5
Now, isolate the variable y by adding 13 to both sides:
3y = 18
Finally, divide both sides by 3 to solve for \(y\):
y = 18/3
y = 6
So, the solution to the equation is y = 6.
Thus, option (d) is correct.

-2y + 6 = -12
what is the answer??
Answer:
9
Step-by-step explanation:
Simplifying
2y + -6 = 12
Reorder the terms:
-6 + 2y = 12
Solving
-6 + 2y = 12
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '6' to each side of the equation.
-6 + 6 + 2y = 12 + 6
Combine like terms: -6 + 6 = 0
0 + 2y = 12 + 6
2y = 12 + 6
Combine like terms: 12 + 6 = 18
2y = 18
Divide each side by '2'.
y = 9
Simplifying
y = 9
Answer:
Y=9
Step-by-step explanation:
Subtract 6 from both sides. Simplify. Dive both sides of the equation by the same term. Simplify. Solution y=9
Trey is taking his friends out to dinner to celebrate graduation. It will cost him $72 to reserve a table, and another $5 per guest. How many people can he invite if he can only spend up to $130?
Answer:
11 people
Step-by-step explanation:
first, youd subtract the table reservation price from the max price.
130 - 72 = 58
then, since each person costs $5, you find the highest multiple of 5.
in this case, its 55, which has 11 groups of 5 in it.
to make sure:
you can then subtract 55 from 58 to make sure there isnt any extra 5's.
58 - 55 = 3.
combine the like terms to create an equivalent expression

For the standard normal distribution, the area between z = 0 and z = 1.70, rounded to four decimal places, is:
Using normal distribution table, the area between z=0 and z=1.70 is the difference between p(z=0) and p(z=1.70). Hence, the area between z=0 and z = 1.70 is 0.4554
Using a normal distribution table :
P(Z < 0) = 0.5 P(Z < 1.70) = 0.95543The Area between z=0 and z= 1.70 is defined as the difference between the probabilities of (z < 1.70) and (z < 0)
P(Z < 1.70) - P(Z < 0) = 0.95543 - 0.5 = 0.45543
Therefore, the area between z = 0 and z = 1.70 rounded to four decimal places is 0.4554
