Step-by-step explanation:
Elevator's starting point = -90ft
Elevator's position after 15s = -20ft
The elevator did move upwards as
-20ft. > -90ft.
_________________________________
Distance covered by the elevator = -20 + -90
= -20 + 90
= 70ft.
Time = 15s
Speed = distance/time
= 70/15
= 4.7ft/s

Emily has 25 crayons and she gets 18 more how many crayons does she have now?
Answer: 43 crayons
Step-by-step explanation:
PLEASE HELP ME! please!
Answer:
yes addison is right because using distributive property would get you from "5 (x + 1) - 2x = 2 (3 + x)" to "5x + 5 - 2x = 6 + 2x". from there, you'd combine like terms and simplify. you get "3x + 5 = 6 + 2x". Subtract 2x on each side, and you get "x + 5 = 6". Subtract 5 on each side, you get "x = 1".

Answer:
It would take her 25.2 minutes
Step-by-step explanation:
6 divided by 5 gives you the 1.2 minutes
Then I would do 1.2 minutes for each lap * 21 laps = 25.2 minutes

A student was working on the problem below: Mr. Braun has $85.00 to spend on pizzas and soda pop for a picnic. Pizzas cost $11.00 each and the drinks cost $0.90 each. Four times as many drinks as pizzas are needed. What is the maximum number of pizzas that Mr. Braun can buy? The student began by writing the let statement: Let x = # of pizzas Then the student wrote the inequality: \displaystyle 11.00(x)+0.90(4x)\ge85.0011.00(x)+0.90(4x)≥85.00 The student made a MISTAKE. Describe the student's error and explain how you know it's wrong. (Do not solve the inequality.)
Answer:
11x + 0.90(4x) ≤ $85
Step-by-step explanation:
Let the number of pizzas be represented by p
Let the number of sodas be represented by s
Mr. Braun has $85.00 to spend on pizzas and soda pop for a picnic. Pizzas cost $11.00 each and the drinks cost $0.90 each.
$11 × p + $0.90 × s = $85
11x + 0.90y ≤ $85.......Equation 1
Four times as many drinks as pizzas are needed.
4p = s
We substitute 4p for s in Equation 1
11x + 0.90(4p) ≤ $85
What is the maximum number of pizzas that Mr. Braun can buy?
The maximum number of pizzas Mr Braun can buy =
11x + 0.90(4p) ≤ $85
The student's error has to do with the inequality sign. The student used greater than or equal to.
The correct sign is less than or equal to because Mr Braun has only $85 to spend.
3n + 7 - 2
Combing like terms
Answer:
Simplifying
3n + 7 + -2 = 0
Reorder the terms:
7 + -2 + 3n = 0
Combine like terms: 7 + -2 = 5
5 + 3n = 0
Solving
5 + 3n = 0
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '-5' to each side of the equation.
5 + -5 + 3n = 0 + -5
Combine like terms: 5 + -5 = 0
0 + 3n = 0 + -5
3n = 0 + -5
Combine like terms: 0 + -5 = -5
3n = -5
Divide each side by '3'.
n = -1.666666667
Simplifying
n = -1.666666667

Factor the linear expression 15x-10 using the greatest common factor of the terms
A.5(3x + 2)
B.5(3x - 10)
C.5(3x- 2)
D.15(x- 2)
Answer:
The answer would be A (3x+2).
Answer: 5(3x-2) - Choice [C]
Step-by-step explanation:
Hii, do you need to factor the expression 15x-10? Np! (:
Note that 15x and -10 have a 5 in common.
To factor it out, we divide 15x and -10 by 5
3x-2 is what we obtain
Next we put parentheses around 3x-2
(3x-2) is what we obtain.
Finally, we put 5 outside the parentheses
5(3x-2)
Voila! There's our answer, cheers! (:

Answer:
The value of y is 12 nd that of x is 7
12 is the value of y in the solution to the following system of linear equations 2x+2=y and 2y=5x-1
The given system of linear equations 2x+2=y abd 2y=5x-1
2x-y=-2...(1)
-5x+2y=-1..(2)
Multiply equation (1) with 2.
4x-2y=-4

if the sum of two numbers is four and the sum of their squares minus three times their product is 76, find the numbers
Answer:
Numbers =(6,-2 )
Step-by step explanation:
Given
the sum of two numbers is four and the sum of their squares minus three times their product is 76,
Let the first term =X
Second term will be=4-x
So
X^2+(4-x)^2-3x(4-x)=76
x^2+16+x^2-8x-12x+3x^2=76
5x^2-20x+16=76
5x^2-20x-60=0
5(x^2-4x-12)=0
So x^2-4x-12=0
x^2-(6-2)x-12=0
x^2-6x+2x-12=0
X(x-6)+2(x-6)=0
(X-6)(X+2)=0
X=6,-2
Let X=6 and -2 then numbers will be 6 and (4-6)=-2

Solve this multi step equation: 7j + 20 = 3j + 40
Answer:
j=5
Step-by-step explanation:
7j+20=3j+40
Step 1: Subtract 3j from both sides.
7j+20−3j=3j+40−3j
4j+20=40
Step 2: Subtract 20 from both sides.
4j+20−20=40−20
4j=20
Step 3: Divide both sides by 4.
4j/4
20/4
j=5
Answer:
j=5
Answer: j = 5
Solve this multi step equation: 7j + 20 = 3j + 40
First step: bring the numbers that don't have a variable on the other side of the equal sign.
7j - 3j = - 20 + 40
*TIP: REMEMBER: when you have a positive number, and you bring it on the other side of the equal sign, it becomes negative; same thing with a negative number. When you have a negative number, and you bring it on the other side of the equal sign, it becomes positive.*
Second step: Solve the equations on both sides.
4j = 20
Final step: (this step is easy) divide 20 by 4
20/4 = 5;
Therefore, j = 5.
