Grace earns $7 for each car she washes. She always saves $21 of her weekly earnings. This week, she
wants to have at least $66 in spending money. How many cars must she wash?
Answer: 13
Step-by-step explanation:
[tex]66\geq 7x-21[/tex]
add 21 both sides
[tex]87\geq 7x[/tex]
divide both sides by 7
[tex]12.4\geq x[/tex]
So more than 13 cars

What is 2x+5=25? I would like to know it step by step please.
Step-by-step explanation:
subtract 5 from 25 and it should look like this
2x=20
divide 2 and your is 10
Answer:
No problem! Well first off, x is 10.
Step-by-step explanation:
So you know that 2 times a certain number, plus 5, is 25. The first step to solving this problem is subtracting 5 from the total (25) to give you 20. This just makes it easier to find x, so you technically don't have to do it. So now, you know that 2 times a certain number equals 20 (because we got rid of the 5). Now, just divide your number (20) by 2, to get that x is 10. Let's check our answer.
2(10) + 5= 2520 + 5= 25
25= 25.
Works out!

Answer:
He would collect 28 cans
Step-by-step explanation:
Ethan = 1/3
84 * 1/3 = 28
Answer:
28 cans were collected by Ethan
Step-by-step explanation:
It says that the total amount of cans collected was 84 cans. Of the 84 total cans, Ethan collected 1/3 of them. To find the number of cans Ethan collected, you would multiply 84 • 1/3. (You could also divide 84 by 3 in this case)
84 • 1/3 = 28

Model With Mathematics A photographer is
placing photos in a mat for a gallery show.
Each mat she uses is x in, wide on each side.
The total area of each photo and mat is
shown
Answer:
a. The possible dimensions of the total area are;
The width of the total area is (2·x + 8) inches
The length of the total area is (2·x + 10) inches
b. The dimensions of the photos are as follows;
The length of the photos are 10 inches
The width of the photos are 8 inches
Step-by-step explanation:
a. Given that the area, A = 4·x² + 36·x + 80
We get;
A = 4 × (x² + 9·x + 20) = 4 × (x + 4) × (x + 5) = (2·x + 8)·(2·x + 10)
Therefore, the possible dimensions of the total area (photo + mat) are;
The width of the total area (photo + mat) = (2·x + 8) in.
The length of the total area (photo + mat) = (2·x + 10) in.
b. The dimensions of the photos alone are shorter than the dimensions of the photo and mat combined by 2·x each
Therefore, we have the dimensions of the photos are as follows;
The length of the photo = (2·x + 10) in. - 2·x in. = 10 in.
The width of the photos = (2·x + 8) in. - 2·x in. = 8 in.

Step-by-step explanation:
Since 2005, the amount of money spent at restaurants in a certain country has increased at a rate of 5% each year. In 2005, about $290 billion was spent at restaurants. If the trend continues, about how much will be spent at restaurants in 2020? PLEASE HELP ME
Answer:
About $603
Step-by-step explanation:
Given data
The time interval 2005-2020= 15 years
The principal amount spent= $290 billion
The rate= 5%
Let us apply the compound interest formula
A=P(1+r)^t
substitute
A=290(1+0.05)^15
A= 290(1.05)^15
A= 290*2.0789
A= $602.881
Hence about $603 will be spent in 2020

A triangle has side lengths 25 in 33 in and 41 in is a front of a cute obtuse or right
Answer
The triangle is an obtuse.
Step-by-step explanation:
25 + 33 + 41 = 99
90 Is a right angel.
But the triangle is 99 which makes it an obtuse.
The sum of squares of the two smaller sides is greater, the triangle is acute.
Acute triangle :To determine whether the triangle is acute, right, or obtuse, add the squares of the two smaller sides, and compare the sum to the square of the largest side.
Given sides of triangle are, [tex]25,33[/tex] and [tex]41[/tex].
Squares of the two smaller sides is,
[tex]=25^{2} +33^{2} \\\\=625+1089=1714[/tex]
Square of third side [tex]=41^{2} =1681[/tex]
Since the sum of squares of the two smaller sides is greater, the triangle is acute.
