\begin{aligned} \overset{\blueD{y}}8\overset{}6&\\ \underline{{} \times \phantom{~~~~} 9}&\\ 4& \end{aligned}
Answer:
5
Step-by-step explanation:
You have to do 6×9 first and since that is a two digit number (gives 54), you have to bring the 5 up to the top in the place of y and add that to the product of the next two numbers you multiply.

А ?B xº 73° What is the value of x?
I just need angle a and x
please answer this question i will give you brainliest!!!!
Answer:
your answer will be 25 .....ok
Answer:
x = 25
Step-by-step explanation:
Given y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 3 when x = 15
3 = 15k ( divide both sides by 15 )
[tex]\frac{3}{15}[/tex] = k, that is k = [tex]\frac{1}{5}[/tex]
y = [tex]\frac{1}{5}[/tex] x ← equation of variation
When y = 5 , then
5 = [tex]\frac{1}{5}[/tex]x ( multiply both sides by 5 to clear the fraction )
25 = x

Answer:
may be A?? i dont really know bt i think A
Answer: B
Step-by-step explanation:
First, let's take the point of the origin so (0,0).
Let's substitute it back into the equations:
0 is x, 0 is y
A: 0> -1 true
B: 0 ≥ -1 also true
C: 0 < -1 not true
D: 0 ≤ -1 not true
So now, for C and D the region containing the (0,0) is the unwanted region (shaded) because the inequality is not true.
However, the graph has the side with point (0,0) unshaded.
So we know that the answer is A or B.
In linear programming signs <> are expressed as dotted lines and ≤≥ as unbroken lines.
The graph has an unbroken line so answer B is correct as it has the sign ≥ (representing an unbroken line) and satisfies the inequality.

A farmer sells 8.7 kilograms of pears and apples at the farmer's market. 3/4 of this weight is pears, and the rest is apples. How many kilograms of apples did she sell at the farmer's market?
Answer:
2.2 kg
Step-by-step explanation:
1000g = 1kg
8700g = 8.7kg
3/4 = 75%
8700 / 100 = 87
87 * 75 = 6525
8700 - 6525 = 2175
2.175kg or if rounded 2.2kg

Step-by-step explanation:
How I would describe the three angles of a triangle is two acute angles and one right angle.
What is a triangle?
A triangle is a three-sided polygon with three edges and three vertices. the sum of angles in a triangle is 180 degrees.
A right triangle is made up of a right angle and two acute angles. A right angle has a value of 90 degrees and an acute angle has a value that is less than 90 degrees.

Lana bought a sports car for $75,700. If the value of her car decreases 4.3% annually.
When using the exponential DECAY formula, what would be the value of r?
Given:
The initial value of the car = $75,700
Decreasing rate = 4.3%
To find:
The value of r in the exponential DECAY formula.
Solution:
The exponential decay formula is:
[tex]y=a(1-r)^t[/tex]
Where, a is the initial value, r is the rate of decay on decimal and t is the time period.
The initial value of the car is $75,700 and its value decreases 4.3% annually. So,
[tex]a=75,700[/tex]
[tex]r=\dfrac{4.3}{100}[/tex]
[tex]r=0.043[/tex]
The required exponential decay formula is:
[tex]y=75,700(1-0.043)^t[/tex]
Therefore, the value of r in the exponential decay formula is 0.043.

a number times 12 is 72. which equation fits this statement?
Answer:
12x = 17
Step-by-step explanation:
So, this is a standard variable equation, so a number (I did x because I'm basic) times, multiplied by, whatever 12 = 72
So a number times 12 is 72 = 12x = 17
Now, if you wanted to actually solve this equation, you just have to do inverse operations:
17 ÷ 12 = 1.4167 (rounded)
So x = 1.4167
