Hello!
To solve this, find the cost of a single light bulb first, by dividing 9 / 5.
9 / 5 ==> 1.80
One light bulb is $1.80
Now, multiply 1.80 by 7.
1.80 * 7 = 12.6
7 light bulbs cost $12.6
Hope this helps! ☺♥
1985year ->275cell phones->100%
1994year -> x cell phones ->100%+360%
40% • (1994-1985)= 40% • 9= 360%
275 cell phone 100%
X cell phones. 100+360%=460%
x=275•460%/100%
x=12420/100
x=1265
99% sure this is a correct answer
x=275 • 460%/100%
x=12,420/100
x=1265
1994-1985= 9 yrs • 40%= 360%
Answer:
Step-by-step explanation:
3x^2 + 5x + 25 when x = 3
= 3(3)^2 + 5(3) + 25
= 3(9) + 15 + 25
= 27 +15 + 25
= 67
We have composite shape consisting of two rectangles with dimensions of one rectangle as 20 feet by (10-6) feet and other rectangle as 6 feet by (20-17) feet.
We know the formula for area of rectangle is given as follows :-
Area of Rectangle = Length x Width
First rectangle's area would be = 20 feet x 4 feet = 80 square feet.
Second rectangle's area would be = 6 feet x 3 feet = 18 square feet.
Area of the room = First rectangle's area + Second rectangle's area.
Area of the room = 80 + 18 = 98 square feet.
Hence, final answer is 98 square feet.
Answer:
a is equal to 0.3
Step-by-step explanation:
12a + 5 -8a =-1
(collect like terms)
12a + 8a= -1 -5
20a = -6
a= -6÷20
a= 3÷ 10
a= 0.3
