Answer:
a) (+) × (?) = (+)
(?) = (+)
b) (-) × (+) = ?
? = (-)
c) (?) × (-) = ?
? is undefined
Step-by-step explanation:
a) (+) × (?) = (+)
From the given equation in the question, by dividing both side of the equation by (+), we have;
((+) × (?))/(+) = (+)/(+)
(?) = (+)/(+) = (+)
Therefore, we have;
(+) × (+) = (+)
(?) = (+)
b) (-) × (+) = ?
From the given equation in the question we apply the operation rules as follows;
(-) × (-) = (+)
(-) × (+) = (-)
Therefore;
(-) × (+) = ? = (-)
? = (-)
c) (?) × (-) = ?
From the rules of multiplication, we have;
(-) × (-) = (+)
(+) × (-) = (-)
Therefore, when (?) = (-), ? = +, from which we have;
(?) ≠ ?, which is an error
Similarly, when (?) = (+), ? = -, therefore, (?) and ?, always changes sign
Therefore, the equation, (?) × (-) = ?, is undefined.

Step-by-step explanation:
3/10 + 4/100 = ???
.
Answer:
34/100
Step-by-step explanation:
Answer:
17/50
Step-by-step explanation:
Hi!
How you want to go about this is first make the 3/10 into 30/100 to make it match up with 4/100.
You want the denominators to both be 100 so they match.
So you would do this by finding 10 x what gets you to 100.
You could eyeball it and see that 10 x 10 = 100 or go backwards (right to left horizontally) and divide 100 / 10 to get 10.
But now what we have is :
30/100 + 4/100
All you have to do is add the first numbers and simplify if possible.
30 + 4 = 34
So :
34/100
To simplify we can divide both numbers by 2 :
34/2
100/2
17/50
And that is our final answer.
I hope this helped!

The sum of 7 and Rita's score is 54
Answer:
the answer to your question is 61
Step-by-step explanation:
54+7=61
Answer:
47
Step-by-step explanation:
54-7=47
I'm assuming we are trying to find Rita's score. We know that the total is 54. "The sum" refers to addition, so we must reverse the problem to find her score
54- 7= 47
Total - 7 = her score

Answer:
78 percent
Step-by-step explanation:
percent increase = (64-36)/36 ×100
= 28/36 ×100 = 0.78×100= 78

– 6 £ 2y < 5
y is an integer.
Write down all the possible values of y.
Answer:
all values less than 5.5
Step-by-step explanation:
Given the inequality expression – 6 + 2y < 5
We are to find all the possible values of x
-6 + 2 y < 5
Add 6 to both sides
-6 + 2y + 6 < 5 + 6
2y < 11
Divide both sides by 2
2y/2 < 11/2
y < 11/2
y < 5.5
hence the possible values of y are all values less than 5.5
Kenji drives 18.4 miles in 16 minutes. He passes a sign, which gives the speed limit as 60 mph. By how much, in mph, did Kenji's average speed exceed the speed limit?
The amount of speed by which kendri exceeded the speed limit is; 9 mph
We are given;
Distance; d = 18.4 miles
Time; t = 16 minutes = (16/60) hours
Now, the formula for speed is;
Speed = distance/time
Thus, let's Calculate kenji's speed;
Kenji's speed = 18.4/(16/60)
Kenji's speed = 69 mph
We are told that the speed limit is to be 60 mph, this means that kendri exceeded the speed limit by;
69 - 60 = 9 mph

Answer:
x = 132º
Step-by-step explanation:
the sum of two angles on the same side is 180º so...
x + 48º = 180º subtract 48º from both sides
x = 132º
If the measure of an angle is twenty
degrees, what is the measurement of
its complementary angle?
Answer:
70 degrees
Step-by-step explanation:

x = 70
Which expression is equivalent to (-5/6) / (10/3)?
Answer:
[tex]\frac{\left(-\frac{5}{6}\right)}{\left(\frac{10}{3}\right)}=-\frac{1}{4}[/tex]
Step-by-step explanation:
Given the expression
[tex]\frac{\left(-\frac{5}{6}\right)}{\left(\frac{10}{3}\right)}[/tex]
Let us solve the expression
[tex]\frac{\left(-\frac{5}{6}\right)}{\left(\frac{10}{3}\right)}=\frac{-\frac{5}{6}}{\frac{10}{3}}[/tex]
Apply fraction rule: [tex]\frac{-a}{b}=-\frac{a}{b}[/tex]
[tex]=-\frac{\frac{5}{6}}{\frac{10}{3}}[/tex]
Divide fractions: [tex]\frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a\cdot \:d}{b\cdot \:c}[/tex]
[tex]=-\frac{5\cdot \:3}{6\cdot \:10}[/tex]
Multiply the numbers: [tex]6\cdot \:10=60[/tex]
[tex]=-\frac{5\cdot \:3}{60}[/tex]
Multiply the numbers: [tex]5\cdot \:3=15[/tex]
[tex]=-\frac{15}{60}[/tex]
Cancel the common factor: 15
[tex]=-\frac{1}{4}[/tex]
Therefore, we conclude that the equivalent expression is:
[tex]\frac{\left(-\frac{5}{6}\right)}{\left(\frac{10}{3}\right)}=-\frac{1}{4}[/tex]

Which of the following could be the equation of the graph shown below?
Check all that apply.
A. y = -4x+ 2
B. 3x + 2y = 6
c. 2x - y = 7
OD y = 5
Answer:
A. y = -4x + 2 and B. 2x + 2y = 6
Step-by-step explanation:
A. y = -4x + 2 This is correct since the displayed picture shows a negative slope. Therefore, m is negative
B. 2x + 2y = 6 This is converted to y = -x +3 So, it is also correct
C. 2x - y = 7 This is converted to y = 2x-7 So, it is not correct
D. y = 5 Y value would have to always be at 5 So, it is not correct
The set of ordered pairs below is a relation. {(0.5,2), (1.5,5), (4.0,12), (6.5,15)} Which relation has the same domain as the given relation?
{(1,5),(2,2),(-3,15),(-8,12)}
{(0.5,1),(1.5,4),(4.0,11),(6.5,14)}
{(2,1,1),(5,2.2),(12,3.3),(15,4.4)}
{(-1,6.5),(-3,1.5),(-6,4.0),(-10,0.5)}
Given:
The set of ordered pairs is
{(0.5,2), (1.5,5), (4.0,12), (6.5,15)}
To find:
Which relation has the same domain as the given relation?
Solution:
We know that, domain is the set of input values or x-values.
For the given set {(0.5,2), (1.5,5), (4.0,12), (6.5,15)}, the domain is
Domain={0.5, 1.5, 4.0, 6.5}
Similarly,
For {(1,5),(2,2),(-3,15),(-8,12)},
Domain = {1, 2, -3,-8}
For {(0.5,1),(1.5,4),(4.0,11),(6.5,14)},
Domain={0.5, 1.5, 4.0, 6.5}
For {(2,1,1),(5,2.2),(12,3.3),(15,4.4)},
Domain = {2, 5, 12, 15}
For {(-1,6.5),(-3,1.5),(-6,4.0),(-10,0.5)},
Domain = {-1, -3, -6, -10}
So, the relation {(0.5,1),(1.5,4),(4.0,11),(6.5,14)} has the same domain as the given relation.
Therefore, the correct option is B.
