Solve by substitution: y=3x and x+y=-32
Answers
Answer:
X=-8, y=-24
Step-by-step explanation:
Y=3x
x+y=-32
substitute value of y (3x) from first equation to the second equation
x+3x=-32
4x=-32
x=-8
solve for y by putting value of x (-8) into either equation
y=3x
y=3(-8)
y=-24

5. Area = 36cm
HM = 12 cm
OE = x
Answers
Answer:
I'm going to guess and say that if HM is one side and OE is the other side of a rectangle, then:
OE = 3 cm
Step-by-step explanation:
36/12 = 3 cm
Answer:Since all the three sides of the triangle are of equal length, we can find the perimeter by multiplying the length of each side by 3. 20 + 20 + 20 = 3 × 20 = 60 cm. Thus, the perimeter of an equilateral triangle is 3 times the length of each side. Area of a two-dimensional shape is the space occupied by the shape.

Answer:
r ≈ 15.90 mP ≈ 63.27°Q ≈ 26.73°Step-by-step explanation:
The triangle is a right triangle, so the length of r can be found using the Pythagorean theorem.
r = √(14.2² +7.15²) = √252.7625
r ≈ 15.8985 ≈ 15.90 . . . meters
__
The angles can be found from the tangent relation.
Tan = Opposite/Adjacent
tan(P) = 14.2/7.15
P = arctan(14.2/7.15) ≈ 63.2738° ≈ 63.27°
Angle Q is the complement of angle P.
Q = 90° -63.27° = 26.73°

Your body mass index (BMI) is your weight in kilograms divided by the square of your height in meters. Many online BMI calculators allow you to enter weight in pounds and height in inches. High BMI is a common but controversial indicator of overweight or obesity. A study by the National Center for Health Statistics found that the BMI of American young men (ages 20 to 29) is approximately normal with mean 26.8 and standard deviation 5.2. People with BMI less than 18.5 are often classed as "underweight." What percent of young women are underweight by this criterion? Sketch and shade the area of interest under a Normal curve.
Answers
Answer:
5.5227%
Step-by-step explanation:
Z score formula = (x-μ)/σ
where x is the raw score = < 18.5
μ is the population mean = 26.8
σ is the population standard deviation = 5.2
For x < 18.5
z = 18.5 - 26.8/5.2
z = -1.59615
Probability value from Z-Table:
P(x<18.5) = 0.055227
Converting to percentage
= 0.055227 × 100
= 5.5227%
Therefore, the percentage of young women that are underweight by this criterion is 5.5227%

1. A rectangle has an area of 12 m2 and a width
of 400 cm. What is the length of the rectangle?
A. 3 cm
B. 30 cm
C. 300 cm
D. 3000 cm
Answers
Answer:
L = 3 cm
Step-by-step explanation:
let lenght be L
First convert area in cm
1 m = 100 cm
12 m = 1200 cm
Area of rectangle = width x lenght
1200 cm = 400 cm x L
1200 /400 = L
3 cm = L

Answers
Answer:
y<−2
Step-by-step explanation:
−6y−2>10
Add 2 to both sides.
−6y>10+2
Add 10 and 2 to get 12.
−6y>12
Divide both sides by −6. Since −6 is negative, the inequality direction is changed.
y<12/-6
Divide 12 by −6 to get −2.

y+7=5x
-3x-2y=-12
solve for x and y
Answers
Answer:
y=3
x=2
Step-by-step explanation:
Making substitution
y+7=5x
y=5x-7
Substituting the y into the other equation
-3x-2(5x-7)=-12
-3x-10x+14=-12
-13x=-14-12
-13x=-26
x=2
We have x=2 then substitute it into the first equation
y+7=5(2)
y+7=10
y=10-7
y=3
So the answer is
y=3
x=2
Answer:
x=2 and y=3

After solving, you can check your work by substituting the values of x and y into the equations and solving for them.
