pls explain the answer
Answer:
[tex]\frac{14}{27}[/tex]
Step-by-step explanation:
[tex]-1\frac{2}{7} = -\frac{9}{7}[/tex] Plug -9/7 in: [tex]-\frac{2}{3}[/tex] ÷ [tex]-\frac{9}{7}[/tex] -2/3 ÷ -9/7 = 2/3 ÷ 9/7 = 2/3 × 7/9[tex]\frac{2}{3}[/tex] × [tex]\frac{7}{9} = \frac{14}{27}[/tex]I hope this helps!

Based on a sample survey, a principal claims that 7 out of 10 students like math. If there are 1300 students, how many would you predict do NOT like math?
Answer:
390
Step-by-step explanation:
find the fraction of those that don't like math
10/10 - 7/10= 3/10
then do 3/10 x 1300 to get 390

Which pair of triangles can be proven congruent by SAS?
Mya applied the distributive property to write the equivalent expressions below
45+ 72 - 9(5 + 9)
What is Mya's error?
Mya did not write the common factor in the correct place,
Mya wrote two expressions that are not equivalent
O Mya did not use the correct operations in the equation,
Mya used a factor that is not common to 45 and 72,
Answer:
Mya wrote two expressions that are not equivalent
Step-by-step explanation:
45 +72 does not equal to 9(5+9)
9(5+9) = 45 + 81
Answer:
D
Step-by-step explanation:
I dislike these kinds of questions. I could argue either of 2 answers - b and d.
b says that her error was that she wrote two expressions that are not equivalent and that is true. She did not write equivalent expressions.
d says she didn't use a common factor to both terms and that is true.
The actual answer is that she made a silly error which we all often do.
8 * 9 is 72
so the distributive property should be
9(5 + 8)
So, what's the answer? I would pick D, but hold your nose when you enter it.

What is the slope of the line parallel to 7x + 4y = -16?
Answer:
The slope of the line that is parallel to the given line is [tex]\frac{-7}{4}[/tex]
Step-by-step explanation:
Parallel lines have the same slopes and different y-intercepts
The slope of the line who has an equation ax + by = c is m = [tex]\frac{-a}{b}[/tex]
Let us use these rules to solve the question
∵ The equation of a given line is 7x + 4y = -16
→ Compare it with the form of the equation above
∴ a = 7 and b = 4
∵ The slope of the line = [tex]\frac{-a}{b}[/tex]
∴ The slope of the line = [tex]\frac{-7}{4}[/tex]
∵ Parallel lines have the same slope
∴ The slope of the line that is parallel to the given line is [tex]\frac{-7}{4}[/tex]
Mario deposited $6,500 in a simple interest account that pays 2.8% interest annually. If Mario leaves the money in the account for 12 years, how much interest will he earn?
Answer:
$2,184
Step-by-step explanation:
Simple interest = (Principal × Rate × Time) / 100
Principal = $6,500
Rate = 2.8%
Time = 12 years
Simple interest = (Principal × Rate × Time) / 100
= (6,500 × 2.8 × 12) / 100
= 218,400 / 100
= 2,184
Simple interest = $2,184
The simple interest on $6,500 at 2.8% for 12 years is $2,184

A phone company charges a base fee of $12 per month plus an additional charge per minute. The monthly phone cost C can be represented by this equation: C=12+a⋅m, where a is the additional charge per minute, and m is the number of minutes used.
Which equation can be used to find the number of minutes a customer used if we know a and C?
A
m=C−12a
B
m=(C−12)−a
C
m=C−12a
D
m=Ca−12
Answer:
It’s actually m = (C - 12) /3 But I don’t see it in the 4 option you have.
Step-by-step explanation:
C = 12+ am
C - 12 = am
(C - 12) /a = m
Answer:
beside in this equation where C=$12 a= the additional charges and m= minutes used the equation would be C m=C-12a

Explain at least one way solving an
inequality is different than solving an
equality.
Answer:
Inequalities are used to demonstrate relationships between numbers or expressions. An inequality describes a relationship between two different values.
The notation
a
<
b
means that
a
is strictly smaller in size than
b
, while the notation
a
>
b
means that
a
is strictly greater than
b
.
The notion
a
≤
b
means that
a
is less than or equal to
b
, while the notation
a
≥
b
means that
a
is greater than or equal to
b
.
Inequalities are particularly useful for solving problems involving minimum or maximum possible values.
Step-by-step explanation:
In 2018, Gretal earned $32 000.
(i) She paid tax of 24% on these earnings.
Work out the amount she paid in tax in 2018
Gretal paid $7680 on tax in 2018.
What is a percentage?"A percentage is a ratio of a number to 100. The symbol % is used to indicate a percentage."
Given
Earning = 32000
Tax paid = 24%
Amount paid on tax = [tex]32000[/tex] × [tex]\frac{24}{100}[/tex]
= $7680
Hence, she paid $7680 on tax.
