Answers
Step by Step
x+10=2x-4
-x. -x
10=x-4
+4. +4
x=14
Answer:
x = 14
Step-by-step explanation:
x + 10 = 2x - 4
x + 10 - 10 = 2x - 4 - 10
x = 2x - 14
x - 2x = 2x - 2x - 14
- x = - 14
- x ÷ - 1 = - 14 ÷ - 1
x = 14
Two months ago, the price, in dollars, of a cell phone was c.
a Last month, the price of the phone increased by 10%. Write an expression for the price of the phone
last month.
b. If the price of the cell phone was originally $399. how much is was it last month?
(From Unit 4, Lesson 8)
Answers
Answer:
Step-by-step explanation:1.1c
The expression for the price last month is 1.1c, and the cell phone was $438.9 last month
The expression for the price last month?The given parameters are:
Initial price = cIncrement = 10%The price last month would be:
Price = Initial price * (1 + Increment)
This gives
Price = c * (1 + 10%)
Evaluate
Price = 1.1c
The actual price last monthWe have:
c = 399
So, the expression becomes
Price = 1.1 * 399
Evaluate
Price = 438.9
Hence, the cell phone was $438.9 last month

Answer:
RQ = RS = 3
Step-by-step explanation:
Since RQ and RS are radii of the circle then they are congruent
let RQ and RS be x , then
Using Pythagoras' identity in right triangle QRS
x² + x² = (3[tex]\sqrt{2}[/tex] )²
2x² = 18 ( divide both sides by 2 )
x² = 9 ( take the square root of both sides )
x = [tex]\sqrt{9}[/tex] = 3
Thus RQ = RS = 3

Beau´s aquarium has 12 fish.Five of the fish are guppies. Which equation can be used to be determine the number of other fish in his aquirium
Answers
Answer:
12 = 5 + x
Step-by-step explanation:
Total fish in the aquarium = 12
Number of guppies fish = 5
Number of other fishes = x
Total fish in the aquarium = Number of guppies fish + Number of other fishes
12 = 5 + x
Subtract 5 from both sides
12 - 5 = 5 + x - 5
7 = x
x = 7
Number of other fishes = x = 7

Answer:
x = 3 and 1/3, or 3.333333...
Step-by-step explanation:
I'm assuming again that you want to find x
–4 + 3 ( 2 – x) = –8
Multiply
-4 + 6 - 3x = -8
Add 4 to both sides
6 - 3x = -4
Subtract 6 from both sides
-3x = -10
Multiply by -1
3x = 10
Divide by 3
x = 10/3
The velocity of a ball thrown upward into the air is given by v(t)= -32t+96 where t is measured in seconds and velocity v in feet per second calculate the displacement of the ball between t=1 and t=4
Answers
Answer:
The displac ment between t = 1 and t = 4 is 272 feet
Step-by-step explanation:
To get the displacement of the ball, we first need to get the equation for the position of the ball with respect to time.
We can do this by differentiating the velocity equation given:
v(t) = -32t +96
integrating between the limits of t = 1 and t = 4, we have
[tex]s = \int\limits^4_1 {-32t +96} \, dt[/tex]
[tex]s(t) = -32t^2/2 +96t[/tex]
[tex]s =[ -16t^2 +96t] t = 4, t =1[/tex]
where t = 4.
s = 256 + (96) =352 feet
Where t = 1
s = 80
Displacement of the ball = 352 -80 = 272ft
The displac ment between t = 1 and t = 4 is 272 feet

A sculptor is planning to make two triangular prisms out of steel. The sculptor will use ABC for the bases of one prism and DEF for the bases of the other prism.
a) is ABC similar to DEF explain
b) suppose the sculptor makes both prisms with the same height. which prism will have a greater volume? how many times greater? show your work
Answers
Answer:
a) yes, they are similar
b) ΔDEF will have a greater area
1.2 times greater (which is the same proportion as 36/30)
Step-by-step explanation:
a) 40/48 = 0.8333
30/6 = 0.8333
Same ratio so they are similar
b) ΔDEF will have a greater area because EF is longer than BC.
area of ΔABC = 1/2(30)(40) = 600 cm²
area of ΔDEF = 1/2(36)(40) = 720 cm²
720/600 = 1.2 x greater
a) 3.x + y = 11
a)
2x-y=4
Answers
Step-by-step explanation:
3x + y = 11 ...(1)
2x - y = 4 ...(2)
From equation (1) we get,
3x + y = 11
x = 11 - y/3
Now, put the value of x = 11 - y/3 in equation (2) we get,
2x - y = 4
2(11 - y/3) - y = 4
22 - 2y/3 - y = 4
22 - 2y - 3y = 12
22 - 5y = 12
5y = 22- 12
5y = 10
y = 10/5
y = 2
Now, Put the value of y = 2 in equation (1)
3x + y = 11
3x + 2 = 11
3x = 11 - 2
3x = 9
x = 9/3
x = 3
Thus, The value of x is 3 and y is 2
FOR VERIFICATION ONLY:3x + y = 11
3(3) + 2 = 11
9 + 2 = 11
11 = 11
2x - y = 4
2(3) - 2 = 4
6 - 2 = 4
4 = 4
Hence, L.H.S = R.H.S

Barry's family traveled 5 7 of the distance to his uncle's house on Saturday. They traveled 1 2 of the remaining distance on Sunday. What fraction of the total distance to his uncle's house was traveled on Sunday?
Answers
Answer: [tex]\dfrac{1}{7}[/tex]
Step-by-step explanation:
Suppose total distance is [tex]x[/tex]
Distance traveled on Saturday is [tex]\frac{5}{7}[/tex] of total distance i.e.
[tex]\Rightarrow \dfrac{5}{7}\times x=\dfrac{5x}{7}[/tex]
Remaining distance is
[tex]\Rightarrow x-\dfrac{5x}{7}=\dfrac{2x}{7}[/tex]
Distance traveled on Sunday is
[tex]\Rightarrow \dfrac{1}{2}\times \dfrac{2x}{7}=\dfrac{x}{7}[/tex]
Now, the fraction of the total distance traveled on Sunday is one-seventh
[tex]\Rightarrow \dfrac{1}{7}[/tex]

Find the number of each type of coin. [Show all

Answers
Answer:
The answer is 8 quarters, 16 nickles, and 32 dimes
Step-by-step explanation:
First, the equation would be (2/4d) x 5 +d x 10 +1/4d x 25= 600 (Don't put 6.00, that's dollars. We put 6 dollars into cents to make it easier.) Then we slowly start to solve: 10/4d + 10d + 25/4d = 600 10d+40d+25d/4 = 600 (Put all of that over 4, not first 25d) 75d= 600 x 4 d=600 x 4/75 (same here put everything over 75) d=32 So then n= 2 x 32/4 = 16 Then n would be equal to : 1/4d= 1/4 x 32 = 8 So your answer would be 8 quarters, 16 nickles, and 32 dimes.Hope this helped :)
