Solve the system of equations and choose the correct answer from the list of
Leya [2.2K]

Answer:

x = -19/2      y = -33/2

Step-by-step explanation:

x - (3x + 12) = 7

x - 3x - 12 = 7

-2x - 12 = 7

-2x = 19

x = -19/2

x - y = 7

-19/2 - y = 7

-y = 33/2

y = -33/2

If the length of a leg of a triangle is 39.2 and the area of the triangle is 63 what is the length of the other leg
Nadya [2.5K]

Answer:

The length of the other leg is 3.21\ units

Step-by-step explanation:

I will assume that the triangle is a right triangle

In a right triangle the legs are perpendicular

so

The area of a right triangle is equal to

A=\frac{1}{2}(a)(b)

where

a and b are the legs of the triangle

In this problem we have

a=39.2\ units

A=63\ units^{2}

substitute the values

63=\frac{1}{2}(39.2)(b)

126=(39.2)(b)

b=126/(39.2)=3.21\ units

PLEASE HELPPPPP PLEAAASEE
nata0808 [166]

Answer:

11%

Step-by-step explanation:

The full circle graph represents 100% of the given population. All populations are given except for "three or more." Adding all percentages of each population should add up to 100%.

No absences (none): 23%

One absence: 45%

Two absences: 21%

Three more absences: unknown.

Let the variable x represent the unknown population.

23% + 45% + 21% + x = 100%

Combine like terms.

89% + x = 100%

Subtract 89% from both sides.

x = 11%

To put it more simply, subtract all the percentages from 100% to get the percent of the missing population. 100 - 23 - 45 - 21 = 11
