Mrs.Brooks lacks 7 from being fice times as old as her son. Six years from now she will lack 3 years from being three times as old as her son is then. Find each of their ages
Answer:
Step-by-step explanation:
Let the age of of Mrs brook be x
Age of her son be y
If Mrs.Brooks lacks 7 years from being five times as old as her son, this means;
x = 5y - 7 ..... 1
six years from now;
Mrs brooks age = x + 6
sons age = y + 6
If Six years from now she will lack 3 years from being three times as old as her son, this means;
x+ 6 = 3(y+6) - 3
x+6 = 3y + 18 - 3
x+6 = 3y + 15 .... 2
substitute 1 into 2;
(5y - 7)+6 = 3y + 15
5y - 1 = 3y + 15
5y-3y = 15 + 1
2y = 16
y = 8
substitute y = 8 into equation 1;
x = 5y - 7
x = 5(8)-7
x = 40-7
x = 33
Hence the mrs brook is 33 years old
her son is 8 years old
A square and an equilateral triangle have the same perimeter. Each side of the triangle is 3 inches longer than each side of the square. Select the equation that will help you find the length of each side of the square.
Answer:
Step-by-step explanation:
Let the length of the side of the square be x
Perimeter of the square = 4x
Let the sides of the triangle be s1, s2 and s3
If each side of the triangle is 3 inches longer than each side of the square, then
s1 = x+3
s2 = x+3
s3 = x+ 3
Perimeter of the triangle P = s1+s2 + s3
If the square and thr triangle have the same perimeter then;
perimeter of square = perimeter of triangle
4x = s1+s2+s3
4x = x+3+ x+3+ x+3
4x = 3(x+3)
Hence the required equation is 4x = 3(x+3) where x is the side of the square.

Answer:
a) 7 days
b) 52 pictures
Step-by-step explanation:
a) If p=pictures and she took 37 pictures, then plug in 37 into p, in the equation the solve.
If you have trouble solving the first step is to subtract 2 from both sides (both sides to cancel out the original 2, and so that 5d can be by itself).
37 = 5d + 2
-2 -2
35 = 5d
The final step is to divide 5 on each side to get d (the number of days by itself). Then you get the answer, d=7, which means that the number of days Lola spent on vacation if she took 37 pictures, would be 7 days.
35 = 5d
5 5
7=d or d=7
b) If d=days and she spent 10 days on vacation, then plug in 10 into d, in the equation then solve.
If you have trouble solving the first step is to multiply 5 by 10. Which will make you end up with 50 + 2
p = 5(10) + 2
p = 50 + 2
Then the final step is the add 50 and 2 together. This will get you the answer p=52, which means that the number of pictures Lola took for the 10 days she was on vacation would be 52 pictures.
Hope this helps!

Answer:
4 5/6 = n
Step-by-step explanation:
5 1/2 = n+ 2/3
Subtract 2/3 from each side
5 1/2 - 2/3 = n+ 2/3 -2/3
5 1/2 - 2/3 = n
Get a common denominator of 6
5 1/2 * 3/3 = 5 3/6
2/3 = 2/3 * 2/2 = 4/6
5 3/6 - 4/6 = n
We need to borrow 1 from the 5 in the form of 6/6
5 3/6 = 4 6/6+ 3/6 = 4 9/6
4 9/6 - 4/6 =n
4 5/6 = n

One batch of meatloaf contains 2 pounds of beef and a cup of bread crumbs. How many pounds of beef and bread crumbs would be needed for 3 batches of meatloaf?
Answer:
3 batches of meatloaf requires 6 pounds of beef and 3 cups of bread crumbs.
Step-by-step explanation:
For pounds of beef
1 batch meatloaf = 2 pounds of beef
3 batches of meatloaf = x
Cross Multiply
x = 3 × 2 pounds of beef
x = 6 pounds of beef
3 batches of meatloaf requires 6 pounds of beef
For bread crumbs
1 batch meatloaf = 1 cup of bread crumbs
3 batches of meatloaf = x
Cross Multiply
x = 3 × 1 cup of bread crumbs
x = 3 cups of bread crumbs
3 batches of meatloaf requires 3 cups of bread crumbs.
Therefore, 3 batches of meatloaf requires 6 pounds of beef and 3 cups of bread crumbs.
Roberto bought a $330,000 house, paying 18% down, and financing the rest at 4.6% interest for 30 years. Her monthly payments are $1387.22. How much will he really pay for her $330,000 house?
Answer:
$558,799.2
Step-by-step explanation:
Given that:
Cost of house = $330 000
Down payment = 18% of cost
Down payment amount = 0.18 * 330,000 = $59,400
Monthly payment = $1387.22
Period of payment = 30 years
Monthly payment after 30 years:
$1387.22 * (30 * 12) = $499,399.2
Hence, amount actually paid :
$59,400 + $499,399.2
= $558,799.2
2 - [7+5 - (-4)]
show work too, please
Answer:
-14
Step-by-step explanation:
2- (7+5 - (-4)) ---- add 7 and 5
2 - (12 - (-4)) ----- subtract -4 from 12
2 - 16
= -14
We will use PEMDAS to solve this equation.
2-[7+5-(-4)]
2-[12-(-4)]
2-[16] You can remove the brackets at this point, if you want.

A bag contains 26 tiles, each with a different letter of the alphabet written on it. You
choose 3 tiles from the bag without looking. What is the probability that you choose
the tiles with the letters A, B, and C?
Answer:
1/26
Step-by-step explanation:
Divide the number of events by the number of possible outcomes. This will give us the probability of a single event occurring. In the case of rolling a 3 on a die, the number of events is 1 (there's only a single 3 on each die), and the number of outcomes is 6.
Jamal works as an electrician's apprentice. He rewired 4 electrical outlets in 1 and one-halfhours. If he works at the same pace for 7.5 hours, how many outlets will he rewire? 5 outlets 13 outlets 20 outlets 30 outlets
Given :
Jamal works as an electrician's apprentice. He rewired 4 electrical outlets in 1 and one-halfhours.
To Find :
If he works at the same pace for 7.5 hours, how many outlets will he rewire.
Solution :
Let, rate of wire rewired in one hour is r.
So, [tex]r=\dfrac{4}{1.5}\ = \dfrac{8}{3}\ rewire/hour[/tex].
Now, number of outlets rewired in 7.5 hours are :
[tex]N=7.5\times\dfrac{8}{3}\\\\N = 20[/tex]
Therefore, he will rewire 20 outlets in 7.5 hours.
Hence, this is the required solution.
Answer:
20 outlets
Step-by-step explanation:
Number of outlets rewired in 1.5 hours = 4
Jamal keeps on working at the same pace 7.5 hours.
To find:
Number of outlets rewired = ?
Solution:
The answer can be found by using the unitary method.
First of all, we need to find number of outlets rewired in 1 hour.
And then, we can multiply with 7.5 to find out the answer.
Number of outlets rewired in 1.5 hours = 4
Number of outlets rewired in 1 hour = [tex]\dfrac{4}{1.5} = \dfrac{40}{15} = \dfrac{8}{3}[/tex]
Number of outlets rewired in 7.5 hours = [tex]\dfrac{8}{3}\times 7.5 = \bold{20}[/tex]
So, 20 outlets can be rewired in 7.5 hours.

Which table only shows values that represent the following relationship
between c and d?
d-C + 20.8
Answer:
The table that correctly represents the given relationship is the one marked as c
Step-by-step explanation:
Table of Values of a Relationship
We are given a relationship between c and d as follows:
[tex]d=c+20.8[/tex]
One of the tables corresponds to the equation above. It's just a matter of testing for the given values of c.
For c=4:
[tex]d=4+20.8 = 24.8[/tex]
For c=6:
[tex]d=6+20.8 = 26.8[/tex]
For c=8:
[tex]d=8+20.8 = 28.8[/tex]
For c=10:
[tex]d=10+20.8 = 30.8[/tex]
-------------------------------------------
It's clear that the table that correctly represents the given relationship is the one marked as c
