Deje que el dinero en la cuenta de ahorros sea 'x'.
Entonces, el dinero en la cuenta después de que se aumentó = x+70
Dado :
▪︎El dinero en la cuenta después de que se aumentó es mayor que 400.
Las declaraciones dadas anteriormente se pueden escribir en una desigualdad como :
[tex] =\tt x + 70 > 400[/tex]
Resolvamos esta desigualdad :
[tex] = \tt \: x + 70 > 400[/tex]
[tex] = \tt \: x > 400 - 70[/tex]
[tex]\color{plum} =\tt x > 330[/tex]
▪︎Por lo tanto, la desigualdad es = x > 330
a. Draw a rectangle with an
area of 39 squares, and
perimeter of 32 units.
a
Answer:
It has side lengths of 3 and 13
Step-by-step explanation:
If it has an area of 39, then let the sides be x and y: thus we get the two relationships:
xy=39
2(x+y)=32
From the second equation, you get x+y=16. Now, rearrange to get y=16-x. You can now plug this into the first equation:
x(16-x)=39 -> 16x-x^2=39 -> x^2-16x+39=0 -> (x-3)(x-13)=0
This implies that x=3, or x=13, which further implies that the side lengths must be 3 and 13.

Given the linear function of 3x – 7y= 14, determine the ordered pair where the line
crosses the y axis. Remember to write your answer in form (x,y)
Answer:
(0, -2)
Step-by-step explanation:
Crosses the y-axis = find the y-intercept. Substitute x = 0 (if you draw a graph, you can see that the point where y crosses the y axis is always 0 for x) into the equation, and you get 3(0) - 7y = 14. Calculate, you get y = -2. Rewrite in coordinates form.

The mass of a basket containing three balls was 3.64 kg. The mass of the same basket and five balls is 5.26 kg. Find the mass of the empty basket in kilograms?
Answer:
1.21
Step-by-step explanation:
5.26 - 3.64 = 1.62
1.62 ÷ 2 because the difference between 3 and 5 is two, the mass of one apple is 0.81 because 1.62 ÷ 2 = 0.81
so now we know one apple weights 0.81
if we multiply that 0.81 x 3 it will equal 2.43, so now the three apples alone wiegh 2.43...so now we look at the total weight of the whole basket with three apples, which is 3.64,
3.64 - the weigth of the apples (2.43)
3.64 - 2.43 = 1.21
the basket alone wieghts 1.21

A number that adds with 2/3 substrate 1/3 will be 8.What should be the number??
Answer:
The number is [tex]\frac{23}{3}[/tex]
Step-by-step explanation:
I am going to call the number x.
A number that adds with 2/3 subtract will 1/3 will be 8.
As an equation, this is:
[tex]x + \frac{2}{3} - \frac{1}{3} = 8[/tex]
Now we solve the equation to find x. So
[tex]x + \frac{2-1}{3} = 8[/tex]
[tex]x + \frac{1}{3} = 8[/tex]
[tex]x = 8 - \frac{1}{3}[/tex]
[tex]x = \frac{24}{3} - \frac{1}{3}[/tex]
[tex]x = \frac{24-1}{3}[/tex]
[tex]x = \frac{23}{3}[/tex]
The number is [tex]\frac{23}{3}[/tex]

A gym teacher placed golf balls into 9
buckets so that each bucket had at least 15
balls. How many total golf balls are there?
Answer:
135
Step-by-step explanation:
9 x 15 = 135
The total number of the golf ball in all buckets is 135 balls using multiply system
Multiply based problem:What information do we have?
Number of buckets = 9
Number of golf ball in each bucket = 15
Total number of golf ball in all buckets = Number of buckets × Number of golf ball in each bucket
Total number of golf ball in all buckets = 9 × 15
Total number of golf ball in all buckets = 135 balls

He needs 18,000 points.
He starts with 100, so subtract the 100 from 18,000 to get how many more points he needs:
18000 - 100 = 17,900 more points.
Divide the points needed by points per word:
17,900 / 50 = 358
He needs at least 358 words.
The inequality would be 50x+100>=18000, where x is the number of words.
