A regular pentagon and an equilateral triangle have the same perimeter. The perimeter of the pentagon is 5(x-2) inches. The perimeter of the triangle is 4(1/2x+2) inches. What is the perimeter of each figure?
Answer:
20 inches.
Step-by-step explanation:
We equate the perimeters:
5(x - 2) = 4(1/2x + 2)
5x - 10 = 2x + 8
5x - 2x = 8 + 10
3x = 18
x = 6
The perimeters = 5(6-2)
= 20 inches.

5.2÷______= 0.052
answer______
Answer:
(1)=100
Step-by-step explanation:
5.2 divided by 10= 0.52 then divide by 10 = 0.052
so instead do 5.2 divided by 100=0.052
Answer: 100
Step-by-step explanation:
Since you change the decimal place two times to the right, you divide it by 100.
A bag contains only red, green, brown and yellow marbles. The probabilities of selecting each colour are shown below. Colour Red Green Brown Yellow Probability 0.2 0.3 x 0.1 Find the probability of selecting a brown marble.
Answer:
0.4
Step-by-step explanation:
Given that:
Probability of :
Red _____Green ___ Brown _____ Yellow
0.2 ______ 0.3 ______ X ________ 0.1
Since the bag contains only red, green, brown and yellow marbles ;
The sum of each color's probability should sum up to 1;
ΣP(x) = 1
Hence,
0.2 + 0.3 + x + 0.1 = 1
0.6 + x = 1
x = 1 - 0.6
x = 0.4
P(brown) = 0.4

State the slope and y-intercept of the graph of y+2x=3
Answer:
Slope(m)=2x
y-intercept(b)=3
Step-by-step explanation:
Answer:
Slope is -2x, Y-Intercept is 3
Step-by-step explanation:
You need to isolate the "y" to get the answer, all you need to do is subtract the "2x" from both sides

A basket contains 2 cartons of white milk, 3 cartons of chocolate milk, and 3 cartons of strawberry milk. A carton of milk is pulled out of the carton without replacement. Then another carton of milk is pulled out without replacement. What is the probability of pulling out 1 carton of chocolate milk followed by another carton of chocolate milk?
Answer: 3/8.
Step-by-step explanation: You have to write a fraction with the amounts of milk in the denominator and the amount of chocolate in the numerator.
Answer:
3/28Step-by-step explanation:
Total number of cartons:
2 + 3 + 3 = 8Let cm be the chocolate milk, there are 3 cartons of cm.
The probability of the first pull of cm is:
P(cm) = 3/8Then we have 7 total left and 2 cm.
The probability of the second cm is:
P(cm) = 2/7Now the probability of the two pulls:
P(cm and cm) = 3/8*2/7 = 3/28The average cost for a gallon of gasoline in 2006 was $2.45. In 2007, the average cost of a gallon of gasoline was $3.29. What is the approximate percent of change in the cost of a gallon of gasoline?

I NEED HELP FAST PLEASE !!!!!!!!!!! The grade of a hill steepness represented as a percent. Jim tracks his walking speed up different hills. What does the rate of change , or slope , represents in this situation a= the rate represents an increases in speed for each 1% b= the rate represents a decrease in speed for 1% grade c = the rate represents a decrease in speed for each 1% grade increase D= the rate represents no change in speed for each 1% grade decrease
Answer:
C
Step-by-step explanation:
slope=walking speed /%
negative slope
so that rules out a and d
and you can see that as the percent increases the speed decreases.
so I think It would be C.

Change to y = mx + b form. 3y - 3x = 9
Answer:
y = x+3
Step-by-step explanation:
3y-3x = 9
3y-3x+3x = 9+3x
3y = 3x+9
3y/3 = 3x/3+9/3
y = x+3
Hey there!
The answer is [tex]y=x+3[/tex]
[tex]3y-3x=9[/tex]
[tex]\frac{3y}{3} -\frac{3x}{3} =\frac{9}{3}[/tex]
[tex]y-x=3[/tex]
[tex]y-x+x=3+x[/tex]
[tex]y=x+3[/tex]

A cinema has 300 seats. 60% are filled. How many are empty? i will give brainliest
Answer:
120 seats
Step-by-step explanation:
Total seats in the hall = 300
Percentage of filled seats = 60 %
Number of seats filled = (60 / 100) 300
= 60 * 3
= 180
Therefore, number of empty seats = 300 - 180
= 120

Can you solve the equation?
Answer:
x=3 and 9
Step-by-step explanation:
; x-3=0
x=3 (change side change mark)
and
[tex] \frac{2}{3} x - 6 = 0[/tex]
[tex] \frac{2}{3} x = 6[/tex]
[tex]x = 6 \times \frac{3}{2} [/tex]
change side change mark.
So, x=9
If u wanna check the answer you can check by substitution x=3 and 9 in equation.
hope it helps you ☺️
