Answer:

Step-by-step explanation:

$\sqrt{50} \ is \ between \ \sqrt{49} \ and \ \sqrt{64}.$

50 is little away from 49 and 50 is far away from 64.

$\sqrt{49} = \sqrt{7*7}=7 \ and \ \sqrt{64}=8$

As 50 is closer to 49 the square root of 50 will be closer to 7 than 8 and so it should be just a little over 7

√50 ≈ 7.1

Ken went to the store for his mother. he spent $2.37 on groceries. in addition, his mother said he could spend 35¢ on candy. wha

Viefleur [7K]

$2.37 (the amount he spent on groceries) + 35¢ (or $0.35 he could spend on candy) = $2.72
Now you subtract this number from the five dollar bill to get the change.
5 - 2.72 = $2.28
His change was $2.28.

{ x - 3y= -3 & x + y= 5 We are to use the graph to solve the given system of equations, then enter your solution below. I ge

Answer:

Solution: (3, 2)

Step-by-step explanation:

It's easier to graph when the equation of the lines are in their slope-intercept form, y = mx + b.

x - 3y = -3

-3y = -x - 3

Divide both sides by -3:

$\frac{-3y}{-3} = \frac{-x - 3}{-3}$

y = 1/3x + 1

where slope = 1/3

y-intercept = 1

x + y = 5

Subtract x from both sides to isolate y:

x - x + y = - x + 5

y = -x + 5

where slope = -1

y-intercept, 5

I started by graphing the y-intercepts of each line. Then, I used the slope of each linear equation (rise over run) to plot the next points on the graph. In the attached screenshot of the graph, x - 3y = -3 is the blue line, while x + y = 5 is the green line. Their intersection occurs at point, (3, 2).

Therefore, the solution is (3, 2).
