Answer:
For the yes/no bit:
step 1: no
step 2: no
step 3: yes
step 4: yes
step 5: no
for the final answer bit: a = 2 3/5 (the last option)
Step-by-step explanation:
yes/no bit:
step 1 is wrong because she didn't multiply [tex]-\frac{5}{4}a[/tex] by -2
step 2 is wrong because she subtracted 1/2 instead of adding it
step 3 is correct because 6 - 1/2 = 11/2
step 4 is correct because she correctly multiplied both sides by 4
step 5 is wrong because she added 5 instead of dividing by -5.

8 cm
Answer:
15 cm hope it helps thank you
The area of the trapezium for the given figure is 35 cm².
What is trapezium?A trapezium is a quadrilateral with four sides where two sides are parallel to each other.
We have,
The area of the trapezium.
= 1/2 x (sum of the parallel sides) x height
Now,
Parallel sides = 6cm and 8cm
Height = 5 cm
Now,
Area.
= 1/2 x (6 + 8) x 5
= 1/2 x 14 x 5
= 35 cm²
Thus,
The area of the trapezium is 35 cm².

Dilation from the origin by scale factor r=1/2 maps quadrilateral ABCD to quadrilateral ABCD not shown
Answer:
C'(4, 4)
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, translation and dilation.
Dilation is the enlargement or reduction in size of a figure. If a figure with point A(x, y) is dilated by a scale factor of k, the new point would be at A'(kx, ky).
Given that quadrilateral ABCD is dilated by a scale factor of 1/2 to form quadrilateral A'B'C'D'.
The vertices of quadrilateral ABCD is given by A(2, 2), B(4, 8), C(8, 8) and D(6, 4).
If quadrilateral ABCD is dilated by 1/2 to form quadrilateral A'B'C'D, the vertices of quadrilateral A'B'C'D would be A'(1, 1), B'(2, 4), C'(4, 4) and D'(3, 2).

The value of the inequality is x ≤ 20/3
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
3x + 10 ≤ 30 be equation (1)
On simplifying , we get
Subtracting 10 on both sides , we get
3x ≤ ( 30 - 10 )
3x ≤ 20
Divide by 3 on both sides , we get
x ≤ 20/3
x ≤ 6.333
Therefore , the value of x is less than or equal to ( 20/3 )
Hence , the inequality is x ≤ 20/3

4x + 5 = 17 what is the value of the x
Answer:
x=3
Step-by-step explanation:
4x+5=17
-5=-5
4x=12
divide both sides by 4
x=3
The solution of the equation 4x + 5 = 17 gives x equals to 3.
Given Equation:
4x + 5 = 17
Now, subtract 5 from both side of the equation is
4x + 5 - 5 = 17 - 5
Then, simplifying the expression
4x = 12
Now, divide both side of the equation by 4 as
4x/ 4= 12/4
x = 3
Therefore, the value of x is 3.
