Answer:

The model is shown in the attached picture. The solution is 10.

Step-by-step explanation:

There are two way of showing a model for 2×5

The tape diagram has 2 equal-sized parts of 5
The tape diagram has 5 equal-sized parts of 2

Both models give the same solution:

5+5=10
2+2+2+2+2=10

In the attached picture we can show two types of diagram.

So first, you need to separate the expression and numbers. For me, i would prefer putting the expressuon on the left hand side and numbers on the right hand side. this will make the solving more clearer and easier to solve.
10p+5=18p-62
10p-18p=-62-5
-8p =-67
p= 8.375

the answer should be
p= 8.375. but however it is not in the option.

Find the variable of each ............

QveST [7]

Answer:

The answer is option d.

To find a we have to first find b

sin 60° = b / 10

b = 10 sin 60°

b = 5√3

sin 30° = b / a

b = 5√3

a = 5√3 sin 30°

a = 10√3

cos 30° = c / a

a = 10√3

c = 10√3 sin 30°

c = 15

cos 60° = d /10

d = 10 cos 60°

d = 5

a = 10√3 , b = 5√3 , c = 15 and d = 5

Hopethis helps.

Find a:27=6:11, find a

trasher [3.6K]

Answer:

a = 14.73

Step-by-step explanation:

This ratio can also be written like this:

$\frac{a}{27} = \frac{6}{11}$

Then you can cross multiply to get

11a = 6 x 27

11a = 162

Divide both sides by 11

11a / 11 = 162 / 11

a = 14.73
