Answer:
Step-by-step explanation:
R = 3x + 9y
They told us that R = 7, y = 6
So you can rewrite the equation as:
R = 3x + 9y
7 = 3x + 9(6)
7 = 3x + 54
Subtract 54 from both sides.
7 - 54 = 3x
-47 = 3x
To find x, you need to divide both sides by 3
3x = -47
x = -47/3
Angel has an action figure collection of 300 action figures. He keeps 267 of the action figures on his wall. What percentage of Angel's action figure collection does he keep on his wall?
Answer:
89% of Angel's action figure collection keeps on his wall.
Step-by-step explanation:
Percentages
To calculate the X% of a quantity Y, we must multiply both numbers and divide by 100:
X% of Y = X * Y / 100
For example, 15% of 780 = 15 * 780 / 100 = 117
If we want to know what percentage is m with respect to n, we proceed as follows:
percentage = m / n * 100%
Anges has a 300 action figures collection, 267 of which are kept on his wall. Here m=267, n=300, thus:
percentage = 267 / 300 * 100% = 89%
89% of Angel's action figure collection keeps on his wall.
A newborn baby has about 26,000,000,000 cells. An adult has about 1.9 X 10^3 times as many cells as a newborn. About how many cells does an adult have? Write your answer in scientific notation.
Answer:
1900
Step-by-step explanation:
26,000,000,000 cells = 2.6 x 10^10 (baby cells)
An adult has about 4.94 times 10 to the thirteenth power
(4.94 x 10^13)/(2.6 x 10^10) = 1.9 x 10^3 = 1900
3. John has $500 and wants to buy a used car but does not have sufficient money.
He decides to save $80 per week for a number of weeks to make up the deficit.
a. Given that he has $500 at the beginning of the first week, how much will he
have saved at the end of the 2nd, 3rd, 45, and 5 weeks?
b. Make a graph to represent the pattern from part a.
c. Create a function that represents the relationship between weeks (w) and
money (m)
d. Explain each part of your function.
Answer:820
Step-by-step explanation:
Since he got $500 the first week multiply 80x4 which is 320+500 is 820$
Lines l and m are perpendicular. If the slope of line m is -4/3, what is the slope of line L.
Answer:
Positive 3/4
Step-by-step explanation:
TO find perpednicular you take the negative reciprical of the slope, so the reciprical of -4/3 is -3/4, now add the negative to get - - 3/4 or 3/4
The value of x must be greater than 0 1 03

Timothy went to a baseball game. After the game, he wanted to ride the bus home. The red and blue line buses both stop at the stadium. * A red line and a blue line bus both leave the stadium at 4:00 p.M. * Red line buses leave the stadium every 6 minutes * Blue line buses leave the stadium every 8 minutes If the game is over at 4:30 p.M., what bus will the kids take if they wanted to leave the stadium at the same time after the game was over?
Answer:
Red bus if it takes no time to reach the bus from stadium.
Blue bus if it takes some time to reach the bus from stadium.
Step-by-step explanation:
Given that:
Red bus leaves the stadium every 6 minutes starting from 4:00 PM.
So, the timings for red bus are:
4:00 PM, 4:06 PM, 4:12 PM, 4:18 PM, 4:24 PM, 4:30 PM, 4:36 PM, 4:42 PM, ......
Blue bus leaves the stadium every 8 minutes starting from 4:00 PM.
So, the timings for Blue bus are:
4:00 PM, 4:08 PM, 4:16 PM, 4:24 PM, 4:32 PM, 4:40 PM, 4:48 PM, ......
Also Given that, game is over at 4:30 PM, so near to that time Red bus leaves at 4:30 PM and then Blue bus leaves at 4:32 PM.
Therefore, the answer is:
Red bus if it takes no time to reach the bus from stadium.
Blue bus if it takes some time to reach the bus from stadium.

Answer:
(3x-4)(2x+5)
Step-by-step explanation:
6x^2 + 7x + 24
= 6x^2 + (15-8)x + 24
= 6x^2 + 15x - 8x + 24
= 3x( 2x+5 ) - 4( 2x+5 )
= (3x-4)(2x+5)
32 is 56% of what number?
Answer:
About 57.14285714, or 57 1/7 (400/7)
Step-by-step explanation:
Suppose the answer is x. This would mean that x multiplied by 0.56 (56%) would equal 32. To isolate x, you would have to divide both sides by 0.56, making the answer 32/0.56, or About 57 and 1/7
the sum of 5 angles of an octagon is 840. What measures of the remaining 3 angles if they are congruent to one another?
Answer:

Step-by-step explanation:
1080-840=240
240÷3=80
80=80=80
congruent means each angles are the same measure.
The TCMS Mustangs played the GCF Grizzlies. On the opening kickoff the ball traveled 35 yds. The running back ran for 17 yards on the next play. The quarterback was sacked for a loss of 5 yds. The next 3 plays had a gain of 4 yards per play. What was the total change in the position of the ball on the field?
Answer: The total change in the position of the ball on the field =24 yards
Step-by-step explanation:
According to integers, every loss is represented by negative integers and every gain is represented by positive integers.
As per given total run = 35+17-5+3(4)
= 59 yards
Change in position = 59 yards - 35 yards
= 24 yards
Hence, the total change in the position of the ball on the field =24 yards
