Answer:

x= 3/2 (3 over 2)

Step-by-step explanation:

2x + 3y= 6

(2x + 3) + (- 3) = 6+ (- 3)

2x + 3 - 3 + 6 - 3

2x = 3

2x/2 = 3/2

x = 3/2

What is the area of a triangle with vertices at (−4, 1) , ​ (−7, 5) ​ , and ​ (0, 1) ​ ?
Mekhanik [1.2K]
Plot the points on a graph. Connect the dots into a triangle. See that the height of the triangle is from y=5 down to y=1. So the height is 4 units.
 Area of a triangle: A = (1/2)BH

You need to find the length of the base. Which is from point (-4,1) to (0,1). You can use the distance formula r just see from the graph that the base is 4 units.

A = (1/2)(4)(4)
A = 8

** Distance formula fyi
d² = (X-x)² + (Y-y)²
with points (X,Y) and (x,y)

A sandbox has an area of 10 2/3 square feet, and the length is 1/4 feet. What is the width of the sandbox?
AlekseyPX

Answer:

The width of the sandbox is 42\frac{2}{3} \ ft.

Step-by-step explanation:

Given,

Area of the sandbox = 10\frac{2}{3}=\frac{32}{3}\ ft^2

Length = \frac{1}{4}\ ft

Solution,

Let the width of the sandbox be 'w'.

Since the sandbox is in shape of rectangle.

So we use the formula of area of rectangle.

Area = Length\times Width

On substituting the given values, we get;

\frac{1}{4}\times w=\frac{32}{3}\\

By cross multiplication method, we get;

w=\frac{32\times4}{3\times 1} =\frac{128}{3} =42\frac{2}{3} \ ft

Hence The width of the sandbox is 42\frac{2}{3} \ ft.

Please help me on this
BabaBlast [244]

Answer:

C. 4 weeks

Step-by-step explanation:

We have the formula

s = 16 \sqrt{7t} + 62

We are looking for the value of t (number of weeks) when s = 150.

So, we isolate t (well, almost isolate, because it would be hard to read)

(\frac{s - 62}{16} )^{2}  = 7t

If we replace s by 150 we get:

7t = (\frac{150 - 62}{16} )^{2} =  (\frac{88}{16} )^{2} =  (5.5 )^{2} = 30.25

We have 7t = 30.25.  If we divide both sides by 7 we get the number of weeks: 4.32... so rounding it down to 4.
