Answer: there is no solution
Step-by-step explanation: 1/4z — 13 is not the same as 1/4 + 13
Say z = 1 that would simplify as -12 3/4 = 13 1/4 they are not the same so there is no solution
If y =-5 when x =12.5 find x when y =15
Answer:
x = -37.5
Step-by-step explanation:
Set up a proportion so -5/12.5 = 15/x
Solve for x so -5x = 15(12.5) so -5x = 187.5 so x = -37.5

If the determinant of this matrix is 24, what is the value of b? A. 4 B. 8 C. 16 D. 20
Answer: B=8
Step-by-step explanation: I got this right on Edmentum.
The value of the variable b will be 8. Then the correct option is B.
What is determinant?The determinant in math is a scalar quantity that is a result of the rows and columns of a matrix form.
If the determinant of this matrix is 24.
The matrix is given below.
[tex]\begin{bmatrix}-5 & 4 & 1 \\5 & -7 & -4 \\-6 & b & 6 \\\end{bmatrix}[/tex]
R₁ ⇒ R₁ + R₂
[tex]\begin{bmatrix}0 & -3 & -3 \\5 & -7 & -4 \\-6 & b & 6 \\\end{bmatrix}[/tex]
C₂ ⇒ C₂ – C₃
[tex]\begin{bmatrix}0 & 0 & -3 \\5 & -3 & -4 \\-6 & b-6 & 6 \\\end{bmatrix}[/tex]
Then the value of b will be
–3[5(b – 6) – (–3)(–6)] = 24
(5b – 30 – 18) = –8
5b = 40
b = 8
Then the correct option is B.

If two ratios are similar we called the ratios to be in proportion.
The length of side x is 6 cm.
What is proportion?If two ratios are similar we called the ratios to be in proportion
We have,
Two shapes:
Consider the bigger shape width = 15 cm and length = 10 cm.
Consider the smaller shape width = 9 cm and length = x cm.
Let the ratio of bigger shape:
= Width / length
= 15/10
Let the ratio of smaller shape:
= Width / length
= 9/x
If the two figures are mathematically similar we can say that the two figures are in proportion.
We can write it as:
15/10 = 9/x
3/2 = 9/x
x = 6
Thus the length of side x is 6 cm.

Sra bought a pair of shoes that were on sale for 30 percent off. If the oringal prices was 29 what is the sale price on the shoes?
Answer:
$20.30
Step-by-step explanation:
Original price = 100% of the price
100% = $29
1% = 29 ÷ 100 = 0.29
Sale percentage = 30%
30% = 0.29 x 30 = 8.70
Since they are asking for the sale price of the shoes, it means the price of the shoes after the discount of the sale percentage.
29 - 8.70 = 20.3
