Answer:
There are 12 quarters and 16 dimes
Step-by-step explanation:
Firstly, we need to know that a quarter is worth $0.25 while a dime is worth $0.10
There are 4 more dimes than quarters;
So if there are x quarters, there are x + 4 dimes
From the question we can get;
0.25(x) + 0.1(x + 4) = 4.6
0.25x + 0.1x + 0.4 = 4.6
0.35x = 4.6-0.4
0.35x = 4.2
x = 4.2/0.35
x = 12
X + 4 = 12 + 4 = 16

Which type of compound inequality is |y−3|−4≤−3?
a.) disjunction
b.) intersection
c.) hole
d.) union
Answer:
b.) intersection
Step-by-step explanation:
The given inequality can be rearranged so that you can see the solution space is one continuous interval.
__
It is described by the intersection of two inequalities.
|y -3| -4 ≤ -3 . . . . . . given
|y -3| ≤ 1 . . . . . . . . add 4
-1 ≤ y -3 ≤ 1 . . . . . "unfolded", the intersection of two inequalities
2 ≤ y ≤ 4 . . . . . . . add 3
This means 2 ≤ y and y ≤ 4, the intersection of the two inequalities.
_____
Additional comment
If the inequality were of the form ...
|y -3| ≥ 1
then it would "unfold" to ...
-1 ≥ y -3 or y -3 ≥ 1
and the solution intervals would be disjoint. The solution would be the union of the solution intervals of the individual inequalities.
Answer:
intersection is right

cancel the four in the left side
3x=24
then divide 3 on both sides
3x/3=24/3
cancel the 3 on the left
x=8

The recipe for beef stew calls for 1/4 teaspoon of pepper for every 3 potatoes. If 9 potatoes are used, how much pepper is needed?
Solve the proportion StartFraction one-fourth over 3 EndFraction = StartFraction p over 9 EndFraction to answer the question.
Explain your steps:
Answer:
3/4 or .75 teaspoons for 9 potatoes.
Step-by-step explanation:
1/4:3 is the original ratio. In order to find the equivalent ratio when 3=9, you would have to multiply.

Isolate the variable by dividing each side by factors that don't contain the variable.
y = 2 − x
Need help please!!!!
Answer:
72

2(x-2)-5=3-2x+6
Answer:
x=9/2
Step-by-step explanation:
First distribute 2
2x-4-5=3-2x+6
Add the like terms on the left side -4-5=-9
2x-9=3-2x+6
Do this with the right side 3+6=9
2x-9=-2x+9
Add 9 from the left side to the right side
2x=-2x+18
Then add 2x from the right side to the left side
4x=18
Divide 4 from both sides
x=18/4 or 9/2
Answer:
9/2
Step-by-step explanation:
2x-4-5= 3-2x+6 distribute 2 through the parentheses
2x-4-5=9-2x add the numbers
2x-9=9-2x calculate the difference
2x+2x-9= 9 move variable to left side and change sign
2x+2x= 9+9 move constant to right side and change sign
4x= 18 collect like terms
x=9/2 divide both sides by 4
