A boy has 11 coins in dimes and quarters. Their value is $1.70. How many of each does he have?
Which of the following equations could be used to solve the problem?
options:
x + (11 - x) = 1.70
25x + 10(11 - x) = 1.70
0.10x + 0.25(11 - x) = 1.70

|-4| + |-5| i need help!!!
Answer:
9
Step-by-step explanation:
The absolute value of any number is just its distance from 0.
-4 is 4 away from 0, so its absolute value is 4.
-5 is 5 away from 0, so its absolute value is 5.
Therefore, the equation is basically just asking what is 4 + 5, which is 9 :D.
Answer:
9
Step-by-step explanation:
The bars around the two numbers imply that it wants you to find the absolute value. Absolute value is the distance a number is from zero since distance is always positive to find the answer just make the number positive. Following this rule l-4l=4 and l-5l=5. Then add them together 4+5=9.

Find the value of x, y and z. Round to the
nearest whole number.
Hello!
We can say that:
x = 35y = 18z = 13Let's go!Calculate x, knowing that angles opposite the vertex have the same value: ↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓
4x - 21 = 2x + 74x - 2x = 7 + 212x = 28x = [tex]\dfrac{28}{2}[/tex] x = 14To know the value of y, just calculate when the angle 4x - 21 ° is worth, as we already have the value of x. Then just do another equation.
4.14 - 2156 - 21 35Now, we calculate:
6y + 37 + 35 = 1806y + 72 = 1806y = 180 - 726y = 108y = [tex]\dfrac{108}{6}[/tex] y = 18Now, we calculate z:
180 - 35 → (35 is the value of 4x - 21 angle, and the adjacent angle of 2x + 7 is same to 10z + 15)= 145Now, we calculate:10z + 15 = 14510z = 145 - 1510z = 130z = [tex]\dfrac{130}{10}[/tex] z = 13Is important stand out what the draw isn't in the correct scale.
Hope this helps!!!! Good studies! ☺

1 The graph below represents a jogger's speed during her 20-minute jog around her neighbor.
Answer:
4) She was jogging at a constant rate.
Step-by-step explanation:
In any graph that has to do with time and speed, anytime the line plateaus (flattens out), that means speed is at a constant rate.

Line f has a slope of -3/4 line g is perpendicular to f. What is the slope of like g
Answer:
Slope of line g = [tex]1\frac{1}{3}[/tex]
Step-by-step explanation:
Line f has a slope of [tex]-\frac{3}{4}[/tex] Line g is perpendicular to f* Mathematics rule: If two lines are perpendicular to each other, then the product of their slopes is equal to -1 .
∴ [tex]-\frac{3}{4}[/tex] × slope of line g = -1
Slope of line g = -1 ÷ [tex]-\frac{3}{4}[/tex] = 4/3 = [tex]1\frac{1}{3}[/tex]

What is an equation?An equation is a mathematical statement that shows that two mathematical expressions are equal.
Given is an equation of a line, we need to find that on which of the given points it lies,
So, we will put the points one by one, the point which stratify the equation will be the answer.
The equation :- y = 2x-4
1) (1, -2)
Put x = 1, y = -2 in the equation,
2(1)-4
= 2-4 = -2
LHS = RHS
Since, point (1, -2) satisfy the equation therefore, the line will pass through it.
Hence, (1, -2) is the coordinates that exists on the line y = 2x - 4

please help me with domain and range of graphs Part 1
Answer:
see the attached for domainRange: (-∞, 4], [3, ∞), [-3, 1]Step-by-step explanation:
The domain is the horizontal extent of the graph. When the graph has arrows on the end, it extends to infinity in the indicated direction.
__
The range is the vertical extent of the graph.
Left Graph
We assume the curve is intended to touch, not cross, the line y=4, so the range is ...
range: (-∞, 4]
__
Middle Graph
We assume the graph continues along the line y=3 to the right indefinitely. Then this value is the minimum of the range.
range: [3, ∞)
__
Right Graph
The low point on the graph is at y=-3, and it looks like the graph continues to the right along the line y=1. Then the range is ...
range: [-3, 1]

The perimeter of a rectangular room is 60 feet. Let x be the width of the room (in feet) and let y be the length of the room (in feet). Select all of the equations below that could model this
situation
A. 2(x + y) = 60
B. 2x + 2y = 60
C. x+2y = 60
D. 2x + y = 60
E. x+y = 60
Answer:
A and B are the correct answers
The equation that represent the given situation is 2 ( x +y) = 60 and 2x +2y = 60, the correct option is A, and B.
What is an Equation?An equation is a mathematical statement formed when two algebraic expressions are equated using an equal sign.
The equations are useful in determination of unknown parameters.
A rectangle is a polygon with four sides, the opposite sides of a rectangle is parallel and equal.
The perimeter of a rectangular room is 60 feet.
The perimeter of a rectangle is given by,
P = 2 ( Length + Breadth)
Let x be the width of the room (in feet).
Let y be the length of the room (in feet).
Substituting the values in the formula to get the equation.
60 = 2 ( x +y)
2 ( x +y) = 60 ---------- (1)
2x +2y = 60 ------------(2)
Therefore, the equations that could model this is situation 2 ( x +y) = 60 and 2x +2y = 60.
