A coin purse contains d dimes and q quarters. There are 35 coins in the purse, and the total value of the coins is $5.60. Create the system of linear equations and use it to find how many dimes and quarters are in the purse.
Answer:
14 dimes, 21 quarters
Step-by-step explanation:
Represent dimes with d and quarters with q.
So: 35 coins means
[tex]d + q = 35[/tex]
1 dime = $0.10 and 1 quarter = $0.25. So, a value of $5.60 means
[tex]0.10d + 0.25q = 5.60[/tex]
So, the system of equations is:
[tex]d + q = 35[/tex]
[tex]0.10d + 0.25q = 5.60[/tex]
Make d the subject in [tex]d + q = 35[/tex]
[tex]d = 35 - q[/tex]
Substitute 35 - q for d in [tex]0.10d + 0.25q = 5.60[/tex]
[tex]0.10d + 0.25(35 - q) = 5.60[/tex]
Open bracket
[tex]0.10d + 8.75 - 0.25q = 5.60[/tex]
Collect Like Terms
[tex]0.10d - 0.25q = 5.60 - 8.75[/tex]
[tex]-0.15q = -3.15[/tex]
Solve for q
[tex]q = \frac{-3.15}{-0.15}[/tex]
[tex]q = 21[/tex]
Substitute 21 for q in [tex]d = 35 - q[/tex]
[tex]d = 35 - 21[/tex]
[tex]d = 14[/tex]
Solve for x:
5x - 4 = 41
Answer:
9
Step-by-step explanation:
5x - 4 = 41
add
5x = 45
divide
x = 9
Answer:
x = 9
Step-by-step explanation:
First, add 4 to both sides.
5x - 4 + 4 = 5x (+4 and -4 cancel one another out, leaving just 5x)
41 + 4 = 45
So, we get 5x = 45
Divide by 5 on both sides.
5x/5 = x (Again, 5 is cancelled out)
45/5 = 9
We get x = 9

Match each irrational number line on which it is represented 2.18112... 2.1823912 2.364125 2.1829391321
Answer:
See Explanation
Step-by-step explanation:
The number lines to make selection from are missing from the question.
However, I've attached 4 number lines, each of which represents each of the given irrational numbers (see attachment)
Number: 2.1823912
This is represented by number line 1
Each point of number line 3 is 0.001 units starting from 2.18;
The point which the red dot is located is between 2.182 and 2.183, but the dot is closer to 2.182.
2.1823912 and 2.1829391321 satisfy this property but number line 2 represents 2.1829391321 (see below for explanation)
So: 2.1823912 is represented by number line 1
Number: 2.1829391321
This is represented by number line 2.
Each point of number line 3 is 0.0001 units starting from 2.182;
The point which the red dot is located is between 2.1829 and 2.1830, but the dot is closer to 2.1829.
From the list of given numbers, only 2.1829391321 satisfy this property.
Number: 2.18112...
This is represented by number line 3.
Each point of number line 3 is 0.01 units starting from 2.11;
The point which the red dot is located is between 2.18 and 2.19.
If number lines 1 and 2 represent 2.1823912 and 2.1829391321, respectively, then number line 3 represents 2.18112.
Number: 2.364125
This is represented by number line 4.
Each point on this number line is 0.1 unit starting from 2.0;
The point which the red dot is located is between 2.30 and 2.40. From the list of given numbers, only 2.364125 satisfy this property.
Answer:
1: 2.1823912 2: 2.364125 3: 2.18112 4: 2.18929391321

ABC form a triangle where BAC equals 90° a B equals 10.8 mm and C equals 1.6 mm find the length of BC give your answer rounded to one DP
Please really need help it’s for a test
Answer:
BC = 10.9 mm
Step-by-step explanation:
The computation of the BC is given below:
Here we applied the pythagorus theorem
AB = 10.8 mm
AC = 1.6mm
BC = ?
Now as we know that
AB^2 + AC^2 = BC^2
10.8mm^2 + 1.6mm^2 = BC^2
116.64mm^2 + 2.56mm^2 = BC^2
BC = 10.9 mm

Solve for a.
a + (−5) = 12
Answer:
a = 17
Step-by-step explanation:
a + (-5) = 12
Open the bracket;
a - 5 = 12
Add 5 to both sides
a - 5 + 5 = 12 + 5
Therefore,
a = 17
Answer:
a=17
Step-by-step explanation:
any number plus a negative number is basically subtracting the absolute value of the negative number. so 12 + 5 = 17

Its mathematics.
Answer:
The height is 15 cm. The volume is 6000 cm³
Step-by-step explanation:
The base is square, so the sides are equal.
√400 = 20. This is the length and width of the cuboid.
The area of the base and the area of the top face are equal, so we subtract 2(400) from the total area to get the area of the remaining 4 faces.
2000 - 800 = 1200 cm²
Divide by 4 to get the area of an individual face.
1200/4 = 300 cm²
We found the width earlier: 20cm
We found the width earlier: 20cm300/20 = 15cm. This is the height.
To find Volume, multiply Area of the base times the height:
400cm²×15cm = 6000cm³
Answer:
this is your answer. best of luck.

\sqrt(x^(2)-14x+49)=x-7
Answer:
infinite solutions
Step-by-step explanation:
note the expression inside the radical is a perfect square, that is
x² - 14x + 49 = (x - 7)², then
[tex]\sqrt{x^2-14x+49}[/tex] = x - 7
[tex]\sqrt{(x-7)^2}[/tex] = x- 7, that is
x - 7 = x - 7
Since both sides are the same then any value of x will make the equation true.
The equation has infinite solutions
Find the measure of angle A
Answer:
24 minus 12 plus 6
Step-by-step explanation:
minus 12
Answer:
43 Degrees
Step-by-step explanation:
(3x + 16) + (6x + 1) + (82) = 180 Degrees
180 - 82 = 98 Degrees
(3x + 16) + (6x + 1) = 9x + 17
9x + 17 = 98
98 - 17 = 81
81 / 9 = 9
x = 9
6(9) + 1 = 55 Degrees
3(9) + 16 = 43 Degrees
55 + 43 + 82 = 180 Degrees
