Answer:
7
Step-by-step explanation:
Remark
The two angles with x in their numerical value are added to get 108
Solution
10x + 2 + 4x + 8 = 108 Collect like terms
14x + 10 = 108 Subtract l0 from both sides.
14x + 10 -10 = 108 - 10 Collect like terms
14x = 98 Divide by 14
x = 98/14
x = 7
In order to solve the problem above, represent the width by x. With this, the length of the rectangular portrait is 1.5x. The perimeter of the rectangle is two times the sum of the length and width. This translates to,
2 (1.5x + x) = 10 ft, x = 2 ft.
Thus, the length of the rectangular portrait is 3 ft.
Answer:
A dot plot titled How many Hours do you Sleep at Night question mark going from 5 to 9. 5 has 2 dots, 6 has 3 dots, 7 has 4 dots, 8 has 3 dots, and 9 has 1 dot.
Step-by-step explanation:
Solution here,
dimentions of is 20 in. by 10 in. by 12 in.
i.e. volume of tank=20×10×12=2400 cu. in.
Again,
the tank holds 10 gallons of water
i.e. 10 gallons of water occupies 2400 cu. in.
so, 1 gallon of water occupies 2400/10 cu.in.
=240 cu.in
Answer:
<h2>D</h2>
Step-by-step explanation:
The dimensions of the portrait are attached.
The total area of the portrait is represented by its width 5+x and its length x+1.
We know by definition that the area of a rectangle is
Where 
is the width and 
is the length.
Using the given expressiones, we have
Therefore, the right answer is D.
