Answer:
5 (12+3)
75
Step-by-step explanation:
so you multiply 5 with the inside of paranthesis. So 5 x 12 and 5 x 3
So its 60 + 15 which is 75. Hope this helps!

Eric started at sea level. He descended 13.7 meters and then ascended 15.2 meters. Write an additional expression in the form Descent + Ascent to represent this situation. Then calculate the sum and explain what it represents.
An additional expression in the form Descent + Ascent to represent this situation is -13.7 + 15.2. The sum will be 1.5 meters.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Eric started at sea level. He descended 13.7 meters and then ascended 15.2 meters.
The expression will be written as,
E = -13.7 + 15.2.
E = 1.5 meters
Therefore, the additional expression in the form Descent + Ascent to represent this situation is -13.7 + 15.2. The sum will be 1.5 meters.

Of the 20 school days last month, there were only 7 when no math or writing homework was
due. There were four days that math and writing homework were both due at the same time.
Math homework was due 7 times total; how many total times was writing due? *
(6 Points)
The value must be a number
Answer:
10
Step-by-step explanation:
The answer is 10 because there are 20 days and no home work is due on 7 of those days so that’s 13 days with homework from math or writing. Then you take the three days where it was just math and subtract that to get 10 days of writing.
Work out the area of a rectangle with base, b =
18mm and perimeter, P = 60mm.
b b
Answer:
Area of rectangle = 216 square mm
Step-by-step explanation:
Base (b ) = 18 mm
width = 'x' mm
Perimeter of rectangle = 2*(base + width)
Perimeter = 60 mm
2*(base + width) = 60 mm
2 *(18 + x ) = 60
2*18 + 2*x = 60
36 + 2x = 60
2x = 60 - 36
2x = 24
x = 24/2
x = 12
Width = 12 mm
Area of rectangle = base * width
= 18 * 12
= 216 square mm
Eleanor and Max used two rectangular wooden boards to make a set for
the school play. One board was 6 feet long, and the other was 5 feet
long. The two boards had equal widths. The total area of the set was
60 square feet. What was the width?
Answer:
[tex]\frac{60}{11}[/tex] feet
Step-by-step explanation:
Rectangle 1:
6 x Width = Area
Rectangle 2:
5 x Width = Area
Total Area = Area of Rectangle 1 + Area of Rectangle 2 = 60 square feet
Take Width as [tex]x[/tex] as the widths of both rectangles are the same:
[tex]5x + 6x = 60\\\\11x = 60\\\\x = \frac{60}{11}[/tex]

Step-by-step explanation:
-3/8 =
-9/24
1/6 =
4/24
-9/24+4/24=-5/24
Answer:
-3
Step-by-step explanation:
multiply to make it a common number so -3/8 times 6/6 and 1/6 times 8/8
so -18/48 times 8/48. Then you multiply the top numbers to get 144/48. Then you simplify or divide so -3.

Samuel gave the cashier $30 to pay for 4 bags of candy he was purchasing for a class party. The cashier gave him $2.04 in change. Each bag of candy costs the same amount.
What is the cost in dollars for each bag of candy?
Answer:
Step-by-step explanation:
First, subtract 2.04 by 30
30 - 2.04 = 27.96
Next, divide 27.96 by 4.
27.96/4 = 6.99
Each bag of candy cost $6.99

What is the x-value of the solution to the system of equations?
5x + 4y = 8
2x − 3y = 17
Answer:
x=4
Step-by-step explanation:
multiply first eq. by 3 and second by 4 to get rid of y
15x+12y=24
8x-12y=68
add the equations
23x = 92
divide both sides by 23
x=92/23=4
Answer:
x = 4
Step-by-step explanation:
Given the 2 equations
5x + 4y = 8 → (1)
2x - 3y = 17 → (2)
Multiplying (1) by 3 and (2) by 4 then adding will eliminate the y- term
15x + 12y = 24 → (3)
8x - 12y = 68 → (4)
Add (3) and (4) term by term to eliminate y, that is
23x = 92 ( divide both sides by 23 )
x = 4

Alain lanzó una piedra desde un puente al río de abajo.
La altura de la piedra (en metros sobre el agua) xxx segundos después de que Alain la lanzó está modelada por:
h(x)=-5x^2+10x+15h(x)=−5x
2
+10x+15h, left parenthesis, x, right parenthesis, equals, minus, 5, x, squared, plus, 10, x, plus, 15
¿Cuál es la altura de la piedra en el momento que la lanza?
Responder:
15m
Explicación paso a paso:
Dada la expresión de la altura de la pelota lanzada modelada por la ecuación;
h (x) = -5x² + 10x + 15
El momento en que se arrojó la piedra es cero, es decir, x = 0 segundos
Sustituya x = 0 en la ecuación y encuentre h (x) como se muestra;
h (x) = -5x² + 10x + 15
h (0) = -5 (0) ² + 10 (0) +15
h (0) = 0 + 0 + 15
h (0) = 15 m
De ahí que la altura de la piedra cuando la arrojes sea de 15 m

To find:
The solution of given equation.
Solution:
We have,
[tex]4(x-3)+5=17[/tex]
Using distributive property, we get
[tex]4(x)+4(-3)+5=17[/tex]
[tex]4x-12+5=17[/tex]
[tex]4x-7=17[/tex]
Adding 7 on both sides, we get
[tex]4x-7+7=17+7[/tex]
[tex]4x=24[/tex]
Divide both sides by 4.
[tex]x=\dfrac{24}{4}[/tex]
[tex]x=6[/tex]
Therefore, the value of x is 6.

5) Solve for x,
107 + 44
8x -23
Answer:
8x + 128??
Step-by-step explanation:
Answer:
To start off, lets label this triangle ABC where A is the top right vertical, the top left verticle is B, and the bottom one is C. Now lets label the 2 points of intersection from the line segment 8x-23 D and E where the left intersection is E and the right is D.
Notice how CE and AE have an arc and that AC was split to get AE and CE. The 2 arcs show us that the intersection E is located at half the line segment.
This is the same on the other line segment BC. So if E and D are half of those line segments then the line segment ED must be half of the parallel segment above it. Because this is true, 2(8x-23)=10x+44
Now we have an equation and we can solve:
2(8x-23)=10x+44
16x-46=10x+44
6x-46=44
6x=90
x=15

I got absolute minimum wrong
9514 1404 393
Answer:
absolute maximum: (3, 27e^-3) ≈ (3, 1.24425)absolute minimum: (-4, -64e^4) ≈ (-4, -3494.28)Step-by-step explanation:
The absolute extremes will be at one of two locations:
where the derivative is zeroat an end of the intervalHere, the absolute maximum occurs where the derivative is zero (and the second derivative is negative).
f'(x) = 3x^2·e^-x -x^3·e^-x = x^2·e^-x·(3 -x) ⇒ f'(3) = 0
The absolute minimum occurs at the left end of the interval, where both x^3 and e^-x have large magnitude.
The minimum is ...
(-4)^3×e^-(-4) ≈ -3494.21 . . . . six significant figures
__
A graph can show you the function tends toward -∞ as x goes to large negative values. Hence, the absolute minimum on an interval beginning in the left half-plane will be at the left end of the interval.
