1. 10 division comes first :)
2. 3 division comes first :)
3. 29 division, then multiplication comes first :)
4. 32 8 x 4 :)
5. $5.00 $10.00 - $5.00 :)
6. 870 48 x 8, then 54 x 9 :)
Glad I could help, and good luck :)
Define your variables:
Q: number of quarters
D: number of dimes
Next, create your equations
Q = 2D-4
25Q+10D=200
Because one variable (Q) is already written in terms of the other variable, D, you can already start solving with substitution.
25(2D-4)+10D=200
50D-100+10D=200
60D=300
D=5
Substitute D back into the other equation to find Q.
Q=2D-4
Q=2(5)-4
Q=6
Substitute D and Q into the second equation to check.
25Q+10D=200
25(6)+10(5)=200
150+50=200
This works, so the answer is right! Bill has 6 quarters and 5 dimes.

Step-by-step explanation: hope i helped
The simplest way would be to use a calculator to evaluate B = arcsin(0.7245)
<span>If you don't have a calculator, the next, more complex way would be to interpolate a table of sines and find the value of the angle whose sine is 0.7245. That is the method that was most widely used before the invention of hand held calculators and after sine tables had been published. </span>
<span>The next, most complex way would be to evaluate terms in the infinite series representation of the arcsine function which is the way the sine tables were developed for publication. That series is </span>
<span>arcsin(x) = x + x³/6 + (3/40)x^5 + (15/336)x^7 + ... </span>
<span>The result for any of those methods would be B = 46.4° </span>
<span>Geometrically, you could: </span>
<span>1) Draw a circle of known radius, R. centered at the origin of a rectangular coordinate system </span>
<span>2) Draw a line parallel to the x axis a distance 0.7245R above the x-axis </span>
<span>3) Draw a line connecting the origin to the rightmost point of intersection between the circle 1) and the line 2). </span>
<span>4) Measure the angle between the line 3) and the +x axis. </span>
<span>The Angle 4) will be the measure of the angle whose sine is 0.7245. </span>
<span>That explains four ways you can find the measure of the angle whose sine is 0.7245.</span>
Answer:
Step-by-step explanation:
6x³ and (-5x³) are like terms
y² and 2y² are like terms
Combine like terms
6x³ + y ² - 5x³ + 2y² = 6x³ - 5x³ + y² + 2y²
= x³ + 3y²
