1. Which equation does not match the diagram? A. 6 +3x= 30
B. 3(x+6) = 30
C. 3x = 30- 6
D. 30 = 3x + 6
Answer:
B
Step-by-step explanation:
The solution is Option B.
The equation which does not satisfy the relation is 3 ( x + 6 ) = 30
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of x in the diagram be = 3
So , the total number of x = 3x
The sum of the values in the box = 30
So , the equation will be
6 + x + x + x = 30
On simplifying the equation , we get
6 + 3x = 30 be equation (1)
a)
6 + 3x = 30
The equation satisfies
b)
3 ( x + 6 ) = 30
On simplifying the equation , we get
3x + 18 = 30
The equation does not satisfy
c)
3x = 30 - 6
Adding 6 on both sides of the equation , we get
3x + 6 = 30
The equation satisfies
d)
30 = 3x + 6
The equation satisfies
Hence , the equation which does not satisfy the relation is 3 ( x + 6 ) = 30

SEE ANSWERS
Answer:
The answer is 35%
Step-by-step explanation:
If we add together 35 and 65 we get 100. This means altogether there are 100 kids in her school. Out of those 100 kids, 35 like scary movies. We can write this as the fraction 35/100. This is equivalent to 0.35 or 35%.
Answer:
35%
Step-by-step explanation:
35+65

The circle graph represents the number of teenagers at a high school who play video
games. If 1,938 students go to the school, about how many students play video games?
Please helppppppppp!!!!! :(
Answer:
the answer is 544
Step-by-step explanation:
i had to figure out how much percent was taking then I added and some subtraction and i got 544
If 1,938 students go to the school, about 1394 students play video games.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given that 1938 students go to school.
And the circle graph represents the number of teenagers at a high school who play video games.
And 259° students out of total angle of circle play video games.
That means 259 percentage of 360,
259 = 360 × percentage of students those play video games of the circle/100
percentage of students those play video games of the circle = 259 x 100 / 360 = 71.94%
And the number of students those play video games is
= 71.94% of 1938
= 1938 x 71.94 / 100
= 1394 students
Therefore, if 1,938 students go to the school, about 1394 students play video games.

Isabel wants to start saving more money so that she can purchase new clothes for college. She has $200 and will add $5 to her savings every day.
Which equation models Isabel's savings, where n represents each day?
Answer:
y = 5n + 200
Step-by-step explanation:
y = mx + b
$5 will be added every day, so 5 is the m and n is the x.
$200 is an extra cost that doesn't repeat, so it's the b.

What additional information can be included in the figure showing kite ABCD with
diagonals AC and D?
A) _B= 20
B) is a perpendicular bisector of
C) 21+ m_C = 180°
OD C = 30
Given:
In ABCD, AB=BC, AD=CD.
To find:
The additional information that can be included in the figure showing kite ABCD with diagonals AC and BD.
Solution:
We know that, a quadrilateral is a kite if,
1. Two pairs of congruent sides which are adjacent to each other.
2. One diagonal is perpendicular bisector of other.
From the given information, we have two pairs of consecutive congruent sides AB=BC and AD=CD.
ABCD is a kite if it holds the second property, i.e., one diagonal is perpendicular bisector of other.
So, the required additional information is "segment BD is perpendicular bisector of segment AC".
Therefore, the correct option is B.
Answer:
B
Step-by-step explanation:
BD is a perpendicular bisector of AC

A family eats at a restaurant and the meal is $65, and they leave a tip of 20% of the price of the meal. What is the total with the meal and the tip?
♡ Answer ♡
$78
♡ Step-by-step explanation ♡
In the problem, it states that the family's meal is $65. At the same time, it is also mentioned that the tip is 20% of the price of their meal. This means that the tip is 20% of $65. In order to figure out the total price with the meal and the tip, we must multiply 20% by $65 in order to get the tip, and add $65 for the price of the meal. The sum will be your answer.
As stated earlier, the first step to this question is to multiply $65 by 20%. 20% in decimal form is 0.2 0.2*$65 equals $13. So, the family left a $13 tip.
The other step in finding the overall amount of money the family used is to add $65 to our previous answer. In this case, our previous answer is $13. We must add $65 to $13 in order to find the total price. $65+$13 is $78.
So, the total (with the meal and the tip) is $78.

Lla must work at least 5 hours per week in her family's restaurant for $8 per hour. She also does yard work for $12 per hour. Lla's parents allow her to work a maximum of 15 hours per week overall. Lla's goal is to earn at least $120 per week.
1. Write a system of Inequalities to represent this situation. Letr be the number of hours worked at the restaurant, and let y be the number of hours of yard work.
2. Graph the Inequalities.
3. What is the maximum number of hours Lla can work at the restaurant and still meet her earnings goal? Explain.
4. What is the maximum amount of money Lla can earn In 1 week? Explain.
Answer:
12a + 8b < 120c
Step-by-step explanation:
to write the inequalities, you have to label the variables. Lets let a be the yard work, b be the work at the family resteraunt, and c be the total hours of work. You would get an equation of:
12a + 8b < 120c
