A bag of coins contains only quarters and dimes.
• 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?
helpp pls
Answer:
Number of dimes in the bag = 90
Number of quarters in the bag = 186
Step-by-step explanation:
Let
x = Number of dimes in the bag
y = Number of quarters in the bag
= 2x + 6
Total = 276
276 = x + 2x + 6
276 = 3x + 6
276 - 6 = 3x
270 = 3x
x = 270/3
= 90
x = 90
Number of dimes in the bag = 90
Number of quarters in the bag = 2x + 6
= 2(90) + 6
=180 + 6
= 186
Total = Number of dimes in the bag + Number of quarters
= 90 + 186
= 276

What is the length of DC?
O 2 units
O 3uníts
O 6uníts
O 9 unit
Answer:
The correct option is;
3 units
Step-by-step explanation:
From the given figure, we have that segment DE is parallel to segment CB of triangle ABC
According to triangle proportionality theorem we have that segment DE which is parallel to segment CB of triangle ABC, divides the other two sides the triangle ABC proportionally
We have;
[tex]\overline {DC}[/tex]/[tex]\overline {AD}[/tex]= [tex]\overline {EB}[/tex]/[tex]\overline {AE}[/tex]
[tex]\overline {DC}[/tex]/9 = 4/12
[tex]\overline {DC}[/tex]= 9 × 4/12 = 3
[tex]\overline {DC}[/tex]= 3 units
The length of the segment DC = 3 units.

[tex]7d + d - 4d - 7 = 5d[/tex]
[tex]8d - 4d - 7 = 5d[/tex]
[tex]4d - 7 = 5d[/tex]
[tex]5d = 4d - 7[/tex]
Subtract sides 4d
[tex] - 4d + 5d = - 4d + 4d - 7[/tex]
[tex]d = - 7[/tex]
Thus the correct answer is Option three.

Answer:
127 degrees
Step-by-step explanation:
If <1 is 53 degrees, then its vertical angle is also 53 degrees. Same side interior angles are supplementary which means they add up 180 degrees.
180 - 53 = 127

Last month, an airline made 2,905 reservations for flights from Cleveland, Ohio to Newark, New Jersey. After 25 cancellations, there were still 18 full flights. Which airplane made the flights?
Solve: -1/2x +2=-x+7
Answer:
x = 10
Step-by-step explanation:
-1/2x + 2 = -x + 7
multiply by 2 so that -1/2x becomes -x
(-1/2x + 2 = -x + 7)2
-x + 4 = -2x + 14
subtract 4 from both sides
-x = -2x + 10
add -2x to both sides
x = 10
