Answer:
Harry = 10 toys
Mark = 20 toys
Sue = 20 toys
Step-by-step explanation:
H + M + S = 50
H = M - 10
S = 2H
Harry = 10 toys
Mark = 20 toys
Sue = 20 toys
Answer:
51.63m^3
Step-by-step explanation:
The figure is made up of a rectangle, triangle and a semi circle
Area of the figure = Area of triangle + rectangle + semicircle
Area of the triangle = 1/2 * base * height
Area of the triangle = 1/2 * 3 * 5
Area of the triangle = 15/2
Area of the triangle = 7.5m^3
Area of the rectangle = Length * Width
Area of the rectangle = 6 * 5
Area of the rectangle = 30m^2
Area of the semicircle = πr²/2
Area of the semicircle = π(3)²/2
Area of the semicircle = 3.14(9)/2
Area of the semicircle = 3.14 * 4.5
Area of the semicircle = 14.13m^2
The area = 30 + 14.13+7.5
Area of the figure = 51.63m^3
Answer:
y=9/4 = 2.25
Step-by-step explanation:
41 hour = 60 minutes
45 min / 60 min = 0.75 hour
170 mph * 0.75 hr = 127.5 miles flown
127.5 - 12.5 = 115
the plane is 115 miles north of the city
Answers:
<h3>x = 3</h3><h3>One solution</h3><h3>Identity</h3>
Step-by-step explanation:
In algebra, the goal is always to isolate the variable, so that its value can be determined.
<h3>Step 1: Use distributive property to remove parentheses</h3>
2x + 4x - 4 = 2 + 4x
<h3>Step 2: Add like terms</h3>
6x - 4 = 2 + 4x
<h3>Step 3: Subtract 4x</h3>
We need all variables on one side to solve, so subtract 4x from both sides.
2x - 4 = 2
<h3>Step 4: Add 4</h3>
2x = 6
<h3>Step 5: Divide by 2</h3>
x = 3
<h3>Step 6: Check</h3>
2(3) + 4(3) - 4 = 2 + 4(3)
6 + 12 - 4 = 2 + 12
14 = 14 ✔
<h3>Step 7: How many solutions?</h3>
The given equation has only one solution.
<h3>Step 8: Identity, a contradiction or neither?</h3>
The given equation is an identity.
<h3>Step 9: Answers</h3>
x = 3
One solution
Identity
