<h3>The number of beads lina has is 31</h3><h3>
Laura made a mistake by adding the constant 7 and variable 4b</h3>
<em><u>Solution:</u></em>
Given that,
Laura wrote and solved the following expression to find the total number of beads Lina has
There are 6 beads in each packet
7+4b = 11b
= 11(6)
=66
From given,
Lina has a total of 7 + 4b beads
Given that, There are 6 beads in each packet
Substitute b = 6
7 + 4(6)
Simplify
7 + 24
Add
31
Thus, she has a total of 31 beads and not 66 beads
Laura made a mistake by adding the constant 7 and variable 4b
But a constant and variable cannot be added

Answer:
y=-1/2+2
Step-by-step explanation:
the y intercept is 2
Its negative because the slope is going down
1/2 because down 1 right 2
Answer:
19Sin A - (10/sin A)
Step-by-step explanation:
We want to simplify;
9Sin A + 3cosec A + 10sin A - 13Cosec A
Let's rearrange it for ease of addition;
(9Sin A + 10sin A) + (3cosec A - 13Cosec A)
>> 19Sin A - 10cosec A
Now, from trigonometric ratios, we know that; Cosec A = 1/Sin A
Thus; 10cosec A = 10/sin A
Thus, we now have;
19Sin A - (10/sin A)
