Able has a younger sister and an older brother.
- Able’s age can be represented by x.
- Able’s sister is 4 years younger than him.
- Able’s older brother is twice as old as he is.
- The combined age of all three siblings is 32.
How old is Able’s younger sister?
9 years
13 years
5 years
3 years
Answer:
5 years
Step-by-step explanation:
1. if able's age is x, then his sister's is x-4, and his brother's is 2x
2. if these sum to 32, then we can formulate the equation x+(x-4)+2x=32
3. now solve for x, 4x-4=32, 4x=36, x=9
4. if able's sister is x-4 years old, she is 9-4, or 5 years old

Answer:
Perimeter is all sides added together, while Area is one side height times length
Step-by-step explanation:
Since your shape is a square all sides are equal so the equation is the same for all sides
Perimeter = 4z+3+4z+3+4z+3+4z+3 or (4z+3)4
14z+12 <= answer for perimeter
Area = (4z+3) (4z+3)
16z^2+12z+12z+9
16z^2+24z+9 <= answer for area

The midpoint of AB is M. If the
coordinates of M are (,-2) and
the coordinates of B are (6,1),
what are the coordinates of A?
a) (-5,-5)
b) (2, -10)
c) (-10, 2)
d) (-13/4,-3/2
e) (-5,5)
Answer:
A
Step-by-step explanation:
the distance between M and point be is 5.5 for the x coordinate and 3 for the y coordinate. to find point b you added 5.5 to to the x and 3 to the y so if you subtract this from point M you get (-5,-5).

bob can draw 14 shapes in 7 minutes how long does it take bob to draw 28 shapes at the same rate
Answer: 14 minutes
Step-by-step explanation:
Because 28 ÷ 2 is 14.
We have to divide the number Bob has to draw by the number of minutes.
We multiply the number of minuted by 2.
Answer is 14
Answer:
14 minutes
Step-by-step explanation:
We can use ratios to solve
14 shapes 28 shapes
---------------- = ----------------
7 minutes x minutes
Using cross products
14x = 28*7
Divide each side by 14
14x/14 = 28*7/14
x = 14
14 minutes

first thing you need to do is look at slopes
the slopes are different then look at the y intersects there the same
and finally they both intersect at the same point.
the correct answer is B and C.

Which table shows a proportional relationship ?? Pls help
Answer:
Option 2
Step-by-step explanation:
If you multiply 2 by 2 you get 4. If you multiply 3 by 2 you get 6. If you multiply 4 by 2, you get 8. If you multiply 5 by 2 you get 10. A proportional relationship is where you can multiply all the numbers by a certain number to get the answer. In this case, all the numbers in the left column could get multiplied by 2 to get the number in the right column.

Answer:
∠3 and ∠2
Step-by-step explanation:
Adjacent angles are angles that have a common side and common vertex which each other.
The first option is incorrect because they don't share a common side. They do share a vertex but that isn't enough to call them adjacent.
The second option is correct because they share a common side and vertex.
The third option is incorrect because they don't share a common side.
The fourth option is incorrect because they don't share a common side. These two angles are congruent and opposite angles.

5(2x-3)=24
Help me in this pleasee
Answer:
x = 3.9
Step-by-step explanation:
5(2x-3)=24
Distribute
10x -15 = 24
Add 15 to each side
10x-15+15 = 24+15
10x = 39
Divide each side by 10
10x/10 = 39/10
x = 3.9

4x-6>6x-20 solve for the inequality
Answer:
x < 7
Step-by-step explanation:
4x - 6 > 6x - 20
Add 6 to both sides.
4x - 6(+6) > 6x -20(+6)
Simplify.
4x > 6x - 14
Subtract 6x from both sides.
4x(-6x) > 6x(-6x) - 14
Simplify.
-2x > -14
Multiply both sides by -1 (reverse the inequality).
(-2x)(-1) < (-14)(-1)
Simplify.
2x < 14
Divide both sides by 2.
2x/2 < 14/2
Simplify.
x < 7
