Hi,
You can write your problem as:
x = 8 + 3y
x + y = 28
So
(8 + 3y) + y = 28
4y = 28 - 8
4y = 20
y = 20/4 = 5
x + y = 28
x + 5 = 28
x = 28 - 5 = 23
The numbers are 23 and 5.
Hope this helps! If my answer was not clear enough or you’d like further explanation please let me know. Also, English is not my first language, so I’m sorry for any mistakes.
Answer:
0.4
Step-by-step explanation:
Given that:
P(debt) = P(D) = Probability of being in debt = 0.7
P(debt n Midwest) = P(Dn M) = probability of being in debt and lives in Midwest = 0.280
The probability that a randomly selected farmer lives in the Midwest given that he is in debt is?
P(M | D) = p(D n M) / p(D)
P(M | D) = 0.280 / 0.7
P(M | D) = 0.4
Answer:
1. C. 28/54
2. A. 5/22
Step-by-step explanation:
1. Simplify each fraction to see which of the four are equal to 4/9.
2. Convert each to a decimal to see which is between 2/11 and 3/11.
Answer:
A. No; Seraphin's first statement is not correct. Because the a-value is positive, the graph should be stretched horizontally by a factor of 6.
Step-by-step explanation:
For 46 minutes you can use the computer for $23.
Given that, you can rent time on computers at the local copy centre for a $7 setup charge and an additional $1.75 for every 5 minutes.
We need to find how much time can be rented for $23.
<h3>What is a linear equation?</h3>
A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant.
Now, every minute charge=1.75/5=$0.35
Let time used be t, so we can write an equation as
7+0.35t=23
Solve the equation for t.
That is, 0.35t=16
⇒t=16/0.35=45.714
⇒t=45.714≈46 minutes
Therefore, for 46 minutes you can use the computer for $23.
