Answer:

x= -3

y= -2

From the first one, if you add 2y to both sides you can plug that into the second one and solve for y. Then, plug y to the first one and solve for x.

X-2y=1
X=1+2y

2(1+2y)+3y=-12
2+4y+3y=-12
2+7y=-12
7y=-12-2
7y=-14
y=-2

x-2*-2=1
x-(-4)=1
x+4=1
x=1-4
X=-3

The correct ois D. -17.5 degrees
Step-by-step explanation:
The daytime temperature in Apple Valley is
falling by 2.5 degrees each day
Therefore, Change in the temperature each day
=-2.5 degrees
Now, we need to find the net change in the daily
temperature after one calendar week
Now, number of days in one calendar week = 7
So, Net change in the daily temperature after
one calendar week = Daily change × Number of
days in one calendar week
Net change in the daily temperature after
one calendar week =-2.5 x7
# Net change in the daily temperature after
one calendar week =-17.5 degrees
Therefore, The correct option is -17.5

A survey of a group’s viewing habits over the last year revealed the following
Tom [10]

Answer:

0.52

Step-by-step explanation:

The computation of the percentage of the group in which none of the three sports watched is shown below:

= gymnastic percentage + baseball percentage + soccer percentage - gymnastic & baseball percentage - baseball & soccer percentage - gymnastic & soccer percentage + three sports percentage

= 0.28 + 0.29 + 0.19 - 0.14 - 0.12 - 0.18 + 0.08

= 0.48

Now the percentage is

= 1 - 0.48

= 0.52

The figure below shows a shaded rectangular region inside a large rectangle:
pshichka [43]

Answer:

b. 58%

Step-by-step explanation:

Calculate the area of the entire rectangle using the formula A = lw.

The lowercase "L" is for length.

"w" is for width.

The lighter square is 10 units long by 5 inches wide.

A = lw

A = (10 in)(5 in)   Multiply

A = 50 in²

Calculate the area for the shaded rectangle, 7 inches by 3 inches.

A = lw

A = (7 in)(3 in)    Multiply

A = 21 in²

Calculate the area for the non-shaded region by subtracting the shaded area from the total area.

50 in² - 21 in² = 29 in²

The chance that a point in the large rectangle will NOT be in the shaded region is 29/50.

Convert this fraction to decimal form by using a calculator. Divide the top number by the bottom number.

29/50 = 0.58

0.58 is in decimal form. To convert it to a percentage, multiply the number by 100.

0.58 = 58%

Therefore the probability that a point chosen inside the large rectangle is not in the shaded region is 58%.
