I am pretty sure your test score has to be an 86.
Answer:
Step-by-step explanation:
We are given the Inequality:
First, we can simplify the expression. On the left side of Inequality, we can cancel 2; on the right side, we can cancel 2 out as well.
Simply, division!
2 divides 2 is 1; 2 divides 10 is 5.
Generally, it is not recommended to write 1 beside the variable nor write 1 as a denominator.
Simplify the expression:-
Therefore, the value of y is less than 5.

Answer:
<em>There are 144 cards in 12 packages</em>
Step-by-step explanation:
<u>Direct Proportion</u>
The number of trading cards is directly proportional to the number of packages. We are given there are 84 cards in 7 packages.
Let x= number of packages, y=total number of cards
The direct variation equation is:
y = m.x
Where m is a constant we need to find by using the given data: y=84 when x=7, thus
84 = 7m
Dividing by 7:
m = 84/7=12
The equation is:
y = 12x
For x = 12 packages:
y = 12*12 = 144 cards
The answer is:
There are 144 cards in 12 packages
Answer:
10°
Step-by-step explanation:
the sum of interior angles of triangle is 180°
so. 8x+x+90°=180°
9x=90°
x=10°
