Area=1/2 times base times height
base=4
height=3
area=1/2 times 4 times 3
area=2 times 3
area=6 square units
One set of magnet with 10% discount would cost
(6.4)*(1-0.10) =
6.4*0.9 = 5.76
For two sets of magnets
5.76*2 =11.52
Answer:
13) 4
14) 7
15) 8
How?
21x+6 = 90 by the alternate exterior angles rule so solve and get 4
11x-2=75 by the Corresponding exteriors angles rule so solve and you get 7
8x-4=60 by the vertical angle rule solve and you get 8
Hope this helps :D
Answer:
First Graph Description
Step-by-step explanation:
A linear function shows as a straight line.
The first graph description describes a straight line.
The second, third, and fourth graph description says that either the line is curved, or that it is a parabola. A parabola is not linear.
A coordinate plane is shown with a line that starts to the left of the y-axis, passing through -1 comma 10, then curving right to pass through the y-axis 7, then curving down to pass through the x-axis at 2
A coordinate plane is shown with a parabola opening downward in an upside-down U shape. The base of the parabola sits at the origin and continues downward on both sides of the y-axis
A coordinate plane is shown. A wavy line begins along the x-axis and moves in intervals downward and back up, dipping down to y equals negative 1 and up to y equals 1.
Hope this helps.
Answer:
<h3>
13, 15, 17</h3>
Step-by-step explanation:
x - an integer then 2x + 1 is an odd number (the smallest one)
consecutive odd numbers increase by 2
so the next odd number (the middle number) is:
2x + 1 + 2 = 2x + 3
and the third (the largest) consecutive is:
2x + 3 + 2 = 2x + 5
the sum of the the two largest numbers is:
2x + 3 + 2x + 5
3 times the smallest number is:
3(2x + 1)
the sum of the two largest is seven less than three times the smallest, so:
2x + 3 + 2x + 5 = 3(2x + 1) - 7
4x + 8 = 6x + 3 - 7
-6x -6x
-2x + 8 = -4
-8 -8
-2x = -12
÷(-2) ÷(-2)
x = 6
2x+1 = 2•6+1 = 13
2x+3 = 2•6+3 = 15
2x+5 = 2•6+5 = 17
Check:
2x+3+2x+5 = 15+3+15+5 = 38
38+7 = 45
45÷3 = 15
