Answers

Answer 1

Answer:

Answer:

The total area of the field is 343 square feet

Step-by-step explanation:

Let us solve the question

∵ There are 7 workers hired to seed a field by hand

∵ Each is given a plot 7 x 7 feet in size

→ The plot has shaped a square because its two dimensions equal

∴ The side of the plot =7 feet

∵ The area of the square = side × side

∴ The area of each plot = 7 × 7

∴ The area of each plot = 49 square feet

→ To find the total area multiply the area of 1 plot by the number

of the workers

∵ The total area = 49 × 7

∴ The total area = 343 square feet

∴ The total area of the field is 343 square feet

How do you solve this? 3w+2<2w+5

Answers

3w + 2 < 2w + 5

First, subtract 2 from both sides. / Your problem should look like: $3w \ \textless \ 2w + 5 - 2$
Second, simplify. / Your problem should look like: $3w \ \textless \ 2w + 3$
Third, subtract 2w from both sides. / Your problem should look like: $3w - 2w \ \textless \ 3$
Fourth, subtract 3w - 2w to get w. / Your problem should look like: $w \ \textless \ 3$

Can someone help me do this ?how do i solve for Y

Answers

7x+5y=20
move y by itself

7x+5y=20
minus 7x from both sides
7x-7x+5y=20-7x
0+5y=20-7x
5y=20-7x
divide both sides by 5
5y/5=(20-7x)/5
y=(20-7x)/5
y=(20/5)+(-7x/5)
$y=4- (7x)/(5)$
