The number of dimes in the bag can be represented by x. The number of quarters is 6 more than twice the number of dimes. There are a total of 276 coins in the bag. What is x, the number of dimes in the bag?
Answer:
The number of dimes is represented by x = 90
Step-by-step explanation:
Given that:
The number of dimes is represented by x
Number of quarters = 6 + 2x
Total number of coins in the bag = 276
To find x, we have:
x + 6 + 2x = 276
3x + 6 = 276
3x = 276 - 6
3x = 270
x = 270/3
x = 90

A rectangle has a length of x inches and a width 2 inches less than the length. If the dimensions were doubled, what would be the area, in square inches , of the new rectangle in terms of x
Answer:
Option (4)
Step-by-step explanation:
Area of a rectangle = Length × width
If the dimensions of the given rectangle is doubled,
Area of the new rectangle = 2(Length) × 2(width)
= 4(Length × width)
= 4(x)(x - 2)
= 4[x² - 2x]
= 4x² - 8x
Therefore, Option (4) will be the correct option.
PLEASE HELP ! Which inequality represents “nine more than three times a number is greater than 21”.
A. 9n > 21
B. 9+ 3 > 21
C. 3n +9 > 21
D. 9n + 3 > 21
Answer:
C
Step-by-step explanation:
Answer:
C. 3n+9>21
Step-by-step explanation:
Ignore the 9 for a second and think about the phrase "3 times a number", if we say n is the number, then 3n is 3 times the number n.
Now we need something that is 9 more than this 3n, that means you add 9 to this, so you have 3n+9.
Finally, this 3n+9 is greater than 21, so we have 3n+9>21.
To add or subtract numbers with the power of ten you need to make sure the exponents match before you do anything to the coefficients
Answer:
is this a true or false question? If so, it's false. To add or subtract, the bases have to match, not the exponents.
Step-by-step explanation:
Answer:
nope it doesn't matter the exponents they don't have to match but you later have to add them and add that many zeros back as the exponents

Question 1 (5 points)
(02.01 LC)
Line segment AB has a length of 5 units. It is translated 3 units to the right on a coordinate plane to obtain line segment A prime B prime. What is the length of A prime B prime? (5 points)
a. 2 units
b. 3 units
c. 4 units
d. 5 units
Answer:
The answer to this question is b. 3 units
Answer:
D. 5 Units
Step-by-step explanation:
A translation is a different way of saying that the shape was moved. So since this is a movement nothing changed about the length of the line segment, meaning the line segment stayed 5 units.

x + 5y - 10
Answer:
y = -1/5x + 2
Step-by-step explanation:
I will assume the "-" is an equal sign. Solve for y.
x + 5y = 10
~Subtract x to both sides
5y = 10 - x
~Divide 5 to everything
y = 2 - 1/5x
~Reorder
y = -1/5x + 2

2X+20 and X+60 I have to solve for X
Answer:
x = 40
Step-by-step explanation:
I don't understand, but I think you mean 2x + 20 = x + 60
So that's what I'm going to solve for if that's wrong tell me what you mean.
2x + 20 = x + 60 (subtract 20 on both sides)
2x = x + 40 (subtract x on both sides)
x = 40

Step-by-step explanation:
[tex] \frac{1}{4} \times 8w = 2w \\ \frac{1}{4} \times ( - 7) = \frac{ - 7}{4} [/tex]
Answer: 2w -7/4
Step-by-step explanation:
1 /4(8w − 7)
Apply the distributive property.
1 /4(8w − 7) + 1/4 ⋅ − 7
Cancel the common factor of 4.
Factor 4 out of 8w.
2w + 1/4 ⋅ -7
Combine 1/4 and -7
2w + ((-7)/4)
Move the negative in front of the fraction.
2w − 7/4
