In this picture, the fact that PQR and PML are similar triangles is important. This means that one triangle can be converted into the other by a scale factor. Among others, this means that

PQ/PR = PM/PL (common property of similar triangles)

Filling in what we know, we get:

(16x+2)/70 = 21/15, which simplifies to

8x+1 = (21*70)/(2*15) = 49
x = 48/8 = 6

rjkz [21]

Answer:

$5n=1.75$

Step-by-step explanation:

Given: tape diagram

To find: an equation to represent the image

Solution:

In the image, the area of the tape diagram indicating 1.75 is equal to the sum of areas of all the five parts in the diagram such that each part indicates n.

So, according to the given information, the equation is $5n=1.75$ .

Here, we have assumed that 1.75 represents an area of the first rectangle, and n represents the area of each of the small rectangle.

Question: F=d+e+t, solve for t.

Komok [63]

F = d + e + t Flip the sides to put t on the left
d + e + t = F Subtract d from both sides
e + t = F - d Subtract e from both sides
t = F - d - e
