For this case we have the following system of two equations with two unknowns:

$y-2x = -2\\y-x = 1$

When solving the system graphically, the solution will be given by the intersection of the lines.

If we look at the attached image, the solution of the system is given by:

$(x, y) = (3,4)$

Product of 21.33 and 2.04 and the sum of 1.115, 3.18, 22.0613and 12.2384

larisa [96]

Step-by-step explanation:

A. Line up the decimals, then multiply as you would with whole numbers:

$21.33 \\\times 2.04 \\ = 43.5132$

B. Line up the decimals, then add as you would with whole numbers:

Note: These decimals aren't lined up exactly.

$1.115 \\ + 3.18 \\ = 4.295$

$22.061 \\ + 4.295 \\ = 26.356$

$26.356 \\ + 12.2384 \\ = 38.5944$

You compare prices of limousines for the spring dance. Company A charges a $250 fee plus $130 for each hour you use the limo. Fo

erastova [34]

155-130=$25
250-125=$125
125/25=5 hours
when 5 hour later it will be the same price, 6 hours later will be higher if using company B hope that helps

Two sides of a triangle have measures 3 ft. and 6 ft. Also, these sides form a vertex whose angle measures 60 degrees. Calculate

Tanya [424]

Answer:

c² = 3² +6² - 2⋅3⋅6⋅cos 60

c = 27ft

Step-by-step explanation:

Since the angle is located in between the sides of the sides, we will use the cosine rule to get the unknown sides

Let c be the missing sides

According to the cosine rule;

c² = a²+ b² - 2abcosC

c² = 3² +6² - 2⋅3⋅6⋅cos 60

c² = 9 + 36 - 36cos60

c² = 45 - 36cos60

c² = 45 - 36(0.5)

c² = 45 - 18

c² = 27ft

Hence the missing attribute is 27ft and the required expression is c² = 3² +6² - 2⋅3⋅6⋅cos 60

R - 9S = 2 3R - 3S = -10

GrogVix [38]

R-9s=2 add 9s to both sides

r=2+9s making 3r-3s=-10 become:

3(2+9s)-3s=-10 perform indicated multiplication on left side

6+27s-3s=-10 combine like terms on left side

6+24s=-10 subtract 6 from both sides

24s=-16 divide both sides by 24

s=-16/24

s=-2/3, making r-9s=2 become:

r-9(-2/3)=2 perform indicated multiplication on left side

r+6=2 subtract 6 from both sides

r=-4

So s= -2/3 and r= -4
