Answer:
-16
Step-by-step explanation:
2xy + 3yz - xyz
x = 2, y = -2, z = 4
First, plug these values into the equation.
2(2)(-2) + 3(-2)(4) - (2)(-2)(4) = ?
Next, multiply the parentheses.
(-8) + (-24) - (-16) = ?
When you add a negative, you are actually subtracting the number. And when you subtract a negative, you are actually adding the number. Apply this to the equation.
-8 - 24 + 16 = ?
Now, simplify from left to right.
-32 + 16
-16
Your answer is -16.

Find the greatest common factor of 7x and 4x?.
Answer:
GCF = x
Step-by-step explanation:
The factor decomposition is:
7 * x for the first term
2 * 2 * x for the second term.
The ONLY common factor is "x", and the maximum power at which it appears in BOTH terms is "1" (one)
Therefore GCF = x

-2x-3y=-7
y=6x-11
If someone answers this and shows work I will give Brainlyest
Answer:
x = 2
y = 1
Step-by-step explanation:
-2x-3y=-7, y=6x-11
-2x - 3(6x - 11) = -7
-2x - 18x + 33 = -7
-2x - 18x = -40
-20x = -40
x = 2
y = 6(2) - 11
y = 12 - 11
y = 1
Answer:
x = 2, y = 1
Step-by-step explanation:
We have a system of equations:
-2x - 3y = -7
y = 6x - 11
Substitute the given value of y into the equation -2x - 3y = -7
-2x - 3 * (6x - 11) = -7
-20x = -7 - 33
-20x = - 40
x = 2
Substitute the given value of x into the equation y = 6x - 11
y = 6x - 11
y = 6 * 2 - 11
y = 1

Answer:
2.3 hours, or 2 hours & 18 minutes
Step-by-step explanation:
we are trying to find h when d is 56.68, so I replaced d with 56.68
[tex]56.68=24.6h+0.1\\[/tex]
subtract 0.1 from both sides
[tex]56.58=24.6h[/tex]
divide both sides by 24.6

5 less than twice the length equals 11 as an algebraic equation
Answer: 2*L - 5 = 11
Step-by-step explanation:
Suppose that we have a rectangle with length L and width W.
Now we know that:
" 5 less than twice the length equals 11"
Then we get:
"twice the length" is written as 2*L
5 less than that is:
2*L - 5
And this is equal to 11, then:
2*L - 5 = 11
This is the algebraic equation we wanted to find,

A finales de 2017, 3.766.000 españoles no tenian trabajo Si el numero
de desocupacios disminuyó un 13% durante el año siguiente ,¿ cuantos
desocupados habia en España a finales de 2018?
Answer:
Total number of unemployment in 2018 = 3,276,420
Step-by-step explanation:
Given:
Total number of unemployment in 2017 = 3,766,000
Decreased in unemployment = 13%
Find:
Total number of unemployment in 2018
Computation:
Total number of unemployment in 2018 = Total number of unemployment in 2017 - Decreased in unemployment
Total number of unemployment in 2018 = 3,766,000 - 13%
Total number of unemployment in 2018 = 3,276,420

Help!! Find the area of the triangle.
Answer:
Area = 60.0 units²
Step-by-step explanation:
First, let's find the height of the triangle using Pythagorean Theorem:
Height = √(11² - 8²)
= √57
Height = 7.5 (nearest tenth)
✔️Find the area:
Area = ½*base*height
Base = 2*8 = 16
Height = 7.5
Plug in the values
Area = ½*16*7.5
Area = 60.0 units² (nearest tenth)

A car travels 136 miles using 7 gallons of gas. At that rate, how far can the car travel using 42 gallons of gas?
Answer:
in 136 miles=7 gallons
?=42 gallon
= 136=7
?=42
cross multiply
136×42=5,712
=5,712÷7=816
Answer:
816 miles
Step-by-step explanation:
136miles/7 g =19.43
19.43 x 42 ≅ 816.06
or
136/7 = X/42
solve for X
42/7 =6, then 136 x6= 816
x = 816 miles
6The table below represents the charges for using the Internet at a cafe. 3 Number of Minutes Amount Charged (in dollars) 7.5 30 R. 120 12 220 Write an equation in slope-intercept form that describes the relationship between the number of minutes, x, and the amount charged, y.
Answer:
Step-by-step explanation:
y=mx+b
m=(y2-y1)/((x2-x1)
m=(12-7.5)/(120-30)
m=0.05
y=0.05x+b, using point (30,7.5)

Which method do you prefer for solving the equation 2^x=16? Explain.
Answer:
I'd just ask ma.th wa.y but...Yhea
Step-by-step explanation:
Create equivalent expressions in the equation that all have equal bases, then solve for
x
Step-by-step explanation:
step 1. 2^x = 16
step 2. ln(2^x) = ln16
step 3. xln2 = ln16
step 4. x = ln16/ln2 = 4ln2/ln2 = 4.
step 5. The method I prefer is using logarithms.
What is the height of a right triangle if its other two sides are 30 centimeters and 10 centimeters long?
Answer:
Step-by-step explanation:
It depends on whether the 30 cm side is the hypotenuse, or one of the legs.
If the 30 cm side is the hypotenuse, then the third side is √(30^2-10^2) = √800 = 20√2 cm
If the 30 cm side is one of the legs, then the hypotenuse is √(30^2+10^2) = √1,000 = 10√10 cm
Jenny read 12 pages on Monday, 25 pages on Tuesday and
the remaining pages on Wednesday. On average she read
23 pages per day during these three days. How many pages
did she read on Wednesday?
Answer:
32
Step-by-step explanation:
Let Wed pages = x
(12 + 25 + x) / 3 = 23 Multiply both sides by 3
12 + 25 + x = 3 * 23 Combine the right
12 + 25 + x = 69
37 + x = 69 Subtract 37
x = 69 - 37
x = 32
32 pages were read on Wed
