5 0

Answer:

fourth option

Step-by-step explanation:

Given

$\frac{2x-1}{y}$ = $\frac{w+2}{2z}$ ( cross- multiply )

y(w + 2) = 2z(2x - 1) = 4xz - 2z ( divide both sides by y )

w + 2 = $\frac{4xz-2z}{y}$ ( subtract 2 from both sides )

w = $\frac{4xz-2z}{y}$ - 2

In Mr. Cannon's class, 44% scored an 80 or above on the semester exam. Which of the following is NOT equivalent to 44% Question

tigry1 [53]

Answer:

11/20

Step-by-step explanation:

22/50 is equivalent because if you multiply 50 by 2 to get 100, then multiply 22 by 2, you get 44 out of 100 (44). For 11/20 if you multiply 20 by 5 to get 100, then multiply 11 by 5, you get 55 out of 100 (55). Do the same thing for all the other ones. I hope this helps! Please mark me brainliest thanks!

Find the area of the figure given to the right. Round to the nearest whole number. 22 15 36 S The area of the figure is ft2

Ede4ka [16]

Answer:

Step-by-step explanation:

Area of left rectangle:

Length = 36 ft

Width = 8

Area1 = length * width

= 36 * 8

= 288 square feet

Area of right rectangle:

Length = 15 ft

Width = 22 - 8 = 14 ft

Area2 = 15 * 14

= 210 square feet

Area of the figure = Area1 + area2

= 288 + 210

= 498 square feet

Which system of linear inequalities Is represented by this graphed solution?

SashulF [63]

Answer:

y ≥ 3x - 1

y < $-\frac{1}{2}x+2$

Step-by-step explanation:

Let the equation of the solid line passing through (x', y') given in graph is,

y = mx + b

Here m = slope of the line

b = y-intercept

Slope of the solid line =

m = $\frac{3}{1}$

m = 3

y - intercept 'b' = -1

Therefore, equation of the line will be,

y = 3x - 1

Since, shaded (blue) area is above the line, inequality that will represent the solution area will be,

y ≥ 3x - 1

For the dotted line,

Slope of the line (m) = $\frac{\text{Rise}}{\text{Run}}$

= $\frac{-2}{4}$

= $-\frac{1}{2}$

y-intercept (b) = 2

Equation of the dotted line → y = $-\frac{1}{2}x+2$

Since, shaded (grey color) area is below the dotted line,

Inequality representing the solution area will be,

y < $-\frac{1}{2}x+2$
