Dave walked to the store at an average speed of 3.5 miles per hour for 0.5 hours. Then he jogged to his friend's house at an average speed of 7 miles per hour for 1.5 hours. What was the total distance in miles that Dave traveled?
Answer:
21 miles
Step-by-step explanation:
s=vt
Vt = 3.5mi/h + 7mi/h
= 10.5mi/h
Tt = 0.5 hr + 1.5hr
= 2 hr
St = 10.5(2hr)
= 21 miles

7n+2 = 4n+17 solve the equation
Answer:
n = -5
Step-by-step explanation:
Solve for n:
n + 2 = 4 n + 17
Hint: | Move terms with n to the left hand side.
Subtract 4 n from both sides:
(n - 4 n) + 2 = (4 n - 4 n) + 17
Hint: | Combine like terms in n - 4 n.
n - 4 n = -3 n:
-3 n + 2 = (4 n - 4 n) + 17
Hint: | Look for the difference of two identical terms.
4 n - 4 n = 0:
2 - 3 n = 17
Hint: | Isolate terms with n to the left hand side.
Subtract 2 from both sides:
(2 - 2) - 3 n = 17 - 2
Hint: | Look for the difference of two identical terms.
2 - 2 = 0:
-3 n = 17 - 2
Hint: | Evaluate 17 - 2.
17 - 2 = 15:
-3 n = 15
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides of -3 n = 15 by -3:
(-3 n)/(-3) = 15/(-3)
Hint: | Any nonzero number divided by itself is one.
(-3)/(-3) = 1:
n = 15/(-3)
Hint: | Reduce 15/(-3) to lowest terms. Start by finding the GCD of 15 and -3.
The gcd of 15 and -3 is 3, so 15/(-3) = (3×5)/(3 (-1)) = 3/3×5/(-1) = 5/(-1):
n = 5/(-1)
Hint: | Simplify the sign of 5/(-1).
Multiply numerator and denominator of 5/(-1) by -1:
Answer: n = -5
Answer:
n = 5

CAN SOMEONE HELP ME ??? This is areas and volumes of similar solids!!!!!! It’s urgent!!
Answer:
Step-by-step explanation:
let x be the unknown volume
5/7=50/x
x=70
Answer:
137.2 m³
Step-by-step explanation:
Given the ratio of sides a : b , then
ratio of volumes = a³ : b³
Here ratio of sides = 5 : 7 , then
ratio of volumes = 5³ : 7³ = 125 : 343
let x be the volume of the larger prism then by proportion
[tex]\frac{50}{125}[/tex] = [tex]\frac{x}{343}[/tex] ( cross- multiply )
125x = 17150 ( divide both sides by 125 )
x = 137.2
That is volume of larger prism is 137.2 m³
Find three consecutive even integers whose sum is -48
Answer:
-15, -16, -17
Step-by-step explanation:
For three consecutive integers, we can divide the sum by 3 to find the middle integer. Then subtract 1 to get the first integer and add 1 to get the third integer.
-48 ÷ 3 = –16
–16 -1 = –15
–16 +1 = –17

A clothing store has 18 suits for sale. 10 of the suits are Blue, and 8 are black. Two suits are chosen to be put on display on the store window. What is the probability that both suits will be black?
Answer:it is ten
Step-by-step explanation:
The probability is the ratio of the favorable event to the total number of events. Then the probability that both suits will be black is 0.183.
What is probability?Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen.

Answer:
y less than or equal to 2x+1
Step-by-step explanation:
Move the slope to the other side and cancel the 4 on the y to get only y. Whatever you do on one side you must do on the other.
Answer:
y≤2x+1
Step-by-step explanation:
slope intercept form= y=mx+b
-8x+4y<=4
-8x+4y≤4
Add 8x to both sides
4y≤8x+4
Divide both sides by 4.

Chanelle deposits $7,500 into the bank. She does not withdraw or deposit money for 6 years. She earns 6% interest during that time. a. How much interest will she have earned at the end of 6 years? She will earn $2,700 interest b. What will the balance be when she is finally able to withdraw her money?
Answer: a. $2700
b. $10200
Step-by-step explanation:
a. The interest she would have earned at the end of the 6 years can be gotten using the formula
= PRT/100
= $7500 × 6% × 6
= $7500 × 6/100 × 6
= $7500 × 0.06 × 6
= $2700
b. Her balance when she wants to withdraw the money would be:
= $7500 + $2700
= $10200

A bag contains 4 sour-apple candies and 3 watermelon candies. One piece of candy is chosen at random and returned to the bag. Then a second piece of candy is chosen at random What is the probability that both pieces of candy chosen will be sour -apple ?
Answer: [tex]\dfrac{16}{49}[/tex]
Step-by-step explanation:
Given: A bag contains 4 sour-apple candies and 3 watermelon candies.
Total candies = 4+3 = 7
If replacement of candy is done, then the probability of getting sour apple will be the same and independent each time .
Probability of selecting sour apple candy= [tex]\dfrac{\text{Number of sour apple candy}}{\text{Total}}[/tex]
[tex]=\dfrac47[/tex]
Now , the probability that both pieces of candy chosen will be sour -apple =[tex]\dfrac47\times\dfrac{4}{7}=\dfrac{16}{49}[/tex]
hence, required probability = [tex]\dfrac{16}{49}[/tex]

Answer:
The length of the rectangle is given as:
(9x + 6)
Step-by-step explanation:
The area of a rectangle is given as:
Length × Width
Area of the rectangle = 45x² − 42x − 48
Width = 5x - 8
We solve for the length of the rectangle by factorising the area of the rectangle
45x² − 42x − 48
45x² - 72x + 30x - 48
(45x² - 72x )+ (30x - 48)
9x(5x - 8) + 6(5x - 8)
(5x - 8)(9x + 6)
