Janie is three years younger than her brother chad the sum of their ages is 27 how old is Janie
Answer:
Janie is 12
Chad is 15
Step-by-step explanation:
27 - 3 = 24
24 : 2 = 12
12 + 3 = 15 (Chad)
27 - 15 = 12 (Janie)
Janie is three years younger than her brother Chad and she is 12 years old
Janie is 3 years younger than her brother Chad.
let
Chad age = x
Janie age = x - 3
The sum of there ages is 27. Therefore,
x + x - 3 = 27
2x - 3 = 27
2x = 30
divide both sides by 2
x = 30 / 2
x = 15
Chad age = 15 years
Janie's age = 15 - 3 = 12 years

I need help ASAP!!!!!
Answer:
y = 50
Step-by-step explanation:
Firstly, let's make an equation. We know that when y is 15, x is 3. Or, in other words, y is 5 times what x is. Therefore we can use the equation, y = 5x.
Now, just plug x into the equation.
y = 5(10)
y = 50

Open the parallel lines translation application. The right set of parallel lines is a translation right 10 units of the left set of parallel lines. Drag the left set of parallel lines and try to move them onto the right set. Are the two sets of parallel lines the same? What does this mean about how parallel lines change when you translate them?
Answer:
when translation appears on the axises for any shape or line, the same line would not compare each other. Just like the parallel lines that I used. These two lines are not compared to each other.

what is the area and perimeter of this triangle
Answer:
A = 2044 sqcm; P = 221 cm (PLEASE DOUBLE CHECK CALCULATIONS!!)
Step-by-step explanation:
the area of a triangle is half of its base times height.
the base and the height must be perpendicular to each other; so they would be 56 and 73.
56(73)/2=2044
the perimeter is the sum of all the sides
73+56+92=221
The area of the right-angled triangle is 2044 cm² and the perimeter of the right-angled triangle is 221 cm.
To find the area and perimeter of a right-angled triangle with dimensions 73 cm, 92 cm, and 56 cm.
Area of a right-angled triangle:
The area of a triangle can be found using the formula:
A = (1/2) x base x height
Plugging these values into the formula, we get:
A = (1/2) x 73 cm x 56 cm
A = 2044 cm²
Therefore, the area of the right-angled triangle is 2044 cm².
Perimeter of a right-angled triangle:
The perimeter of a triangle is the sum of all its sides.
In this case, the sides of the triangle are 73 cm, 92 cm, and 56 cm.
Perimeter = 73 cm + 92 cm + 56 cm
Perimeter = 221 cm
Therefore, the perimeter of the right-angled triangle is 221 cm.

Over the next 15 months you have to read at least 75 books. You have to read x books per month. The inequality "75 is greater than or equal to 15x" represents this situation. Solve the inequality to find the number of books you have to read per month.
Answer:
you have to read at least 5 books per month (on average)
Step-by-step explanation:
The given inequality is incorrect. "At least 75" means "greater than or equal to 75", so the inequality should be ...
15x ≥ 75
x ≥ 5 . . . . . . divide by 15
You have to read at least 5 books per month.

Step-by-step explanation:
Using order of operations, we have to divide 32 by 8 first since its in parentheses, then add and subtract from left to right, so: (32/8)+27-11 = 4 + 27 - 11 = 31 - 11 = 20

Step-by-step explanation:
-12x+(-4)=56
rewrite the equation to -12x-4=56
add 4 to both sides
-12x=60
Divide by -12 on both sides
x=-5
-2.1x+(-3.9)=10.8
-2.1x-3.9=10.8
-2.1x=14.7
divide by -2.1 on both sides
x=-7

Answer:8 Dollars
Step-by-step explanation: The whole is 100 so you add 50 and 10 together which is the lunch and candy which equals 60 then you subtract the whole number 100 by 60 giving you 40 which is the percentage of 20 that was spent on the spirit shirt.And the way I do it is 10 percent of 20 is 2 so times 2 by 4 which gives you 8 dollars.

With slope = 1/4
Answer:
y = 1/4x + 1.5
Step-by-step explanation:
To solve a problem like this we can use the formula y - y1 = m(x - x1), in which y1 is the y coordinate, x1 is the x coordinate, and m is the slope.
Equation:
y - 1 = 1/4(x + 2)
y - 1 = 1/4x + 0.5
y = 1/4x + 1.5
Answer:
