51-34 gives us QR=17

Needs to have same relation as the known side 17/34=.5

So

14*2=28

To check

14/28=.5

It worked so PT=28

Answer:

Step-by-step explanation:

1. find ratio of small to large triangle (6:18 = 1:3 / 8:24 = 1:3)

2. find blank side of smaller triangle (if ratio is 1:3 then take the large triangle side that matches the smaller unknown side and divide by 3 to size down the line to find unknown side)

21m/3m = 7m

Answer = 7m

Solve the following equation 3 by X + 1 is equal to 5 by 2 X linear equation

dangina [55]

Answer:

x = 5

Step-by-step explanation:

A by B is simply $\frac{A}{B}$

3 by x + 1 is $\frac{3}{x + 1}$

5 by 2x is $\frac{5}{2x}$

So, the equality is ;

$\frac{3}{x + 1}$ = $\frac{5}{2x}$

Cross multiply and solve the inequality;

3(2x) = 5(x + 1)

6x = 5x + 5

6x -5x = 5

x = 5

If the gradient of the line joining the points (-3,-7) and (4,p) is 3/5, find the value of P.

adelina 88 [10]

Given:

Two points (-3, -7) and (4, p).

To find the value of P if the gradient is 3/5:

The gradient in a linear equation is the same thing as the slope of the line.

So, the formula is,

$\begin{gathered} m=\frac{y_2-y_1}{x_2-x_1} \\ \frac{3}{5}=\frac{p-(-7)}{4-(-3)} \\ \frac{3}{5}=\frac{p+7}{7}\Rightarrow3(7)=5(p+7) \\ 21=5p+35 \\ 5p=21-35 \\ 5p=-14 \\ p=-2.8 \end{gathered}$

Hence, the value of p is -2.8.

Find two consecutive even integers whose some is 66

marusya05 [52]

2 consecutive even integers....x and x + 2

x + x + 2 = 66
2x + 2 = 66
2x = 66 - 2
2x = 64
x = 64/2
x = 32

x + 2 = 32 + 2 = 34

ur 2 integers are : 32 and 34
