Answer:

$x=3\frac{1}{2}$

Step-by-step explanation:

$\frac{4}{2} :\frac{7}{x}$

x · 4 = 7 · 2

4x = 14

4x ÷ 4 = 14 ÷ 4

x = 3.5

Answer:

7/2 =x

Step-by-step explanation:

The triangles are similar so we can write a ratio to solve

2 4

---- = -------

x 7

Using cross products

2*7 = 4x

14 = 4x

14/4 = 4x/4

7/2 =x

What is the slope of the line with the equation -5 - x = y?

alisha [4.7K]

In the general form of the equation y = mx + c, the slope is given by m.
The equation from the question can be rearranged a little to give y = -x -5, thus we can now compare directly with the general form above and see that m = -1, and so the answer is B.

What is the measure of the hypotenuse? <br> A. 17<br> B. 289<br> C. 169<br> D. 13

vlabodo [156]

It would be: x² = 5² + 12²
x² = 25 + 144
x = √169
x = 13

In short, Your Answer would be Option D

Hope this helps!

The area of a trapezium is 800 cm2

svlad2 [7]

Answer:

The distance between the parallel sides is 20cm.

Step-by-step explanation:

Area of a trapezoid:

$A=\frac{a+b}{2}\times h$

where a and b are the 2 bases, and h is the height. The value we're trying to find here is the height.

3 of the 4 variables in this equation are already given:

A = 800

a = 48

b = 32

Just plug those in and solve for h:

$\rightarrow 800=\frac{48+32}{2}\times h\\\rightarrow 800=\frac{80}{2}\times h\\\rightarrow 800=40\times h\\\rightarrow 800\div40=h\\\rightarrow h=20$
