please guys someone help i need the answer
Step-by-step explanation:
2x + y + x+ 2y = 180
3x + 3y = 180
3y +20+2x+y=180
4y + 2x = 160
3x + 3y = 180
2x + 4y = 160
elimination
6x + 6y= 360
6x + 12y = 480
= 6y = 120
y= 20
substitute
3x + 3y = 180
3x + 3(20)= 180
3x + 60 = 180
3x = 120
x= 40
x+2y
40+2(20)=80
<4=<8= 80°
<7=180-<8=<180-80= 100°
angle 7 = 100°
angle 8 = 80°
Three-quarters of a number is 2 bigger than two-thirds of the number.
Determine the number.
Answer:
0
Step-by-step explanation:
3/4.x = 2. 2/3.x
↔ x = 0
The required number after simplification of the given statement of the equation is equal to 24.
Let's call the number we want to find "x."
According to the given information:
Three-quarters of the number is 2 bigger than two-thirds of the number.
Mathematically, we can express this as the following equation:
(3/4) × x = (2/3) × x + 2
Now, let's solve for "x":
Get rid of the fractions by multiplying everything by the least common multiple (LCM) of 4 and 3, which is 12.
12× (3/4) × x = 12 × (2/3) × x + 12× 2
Simplify both sides:
9x = 8x + 24
Isolate the "x" term on one side. To do this, we need to move the 8x to the left side by subtracting 8x from both sides:
9x - 8x = 8x + 24 - 8x
Simplify further:
x = 24
Therefore, the number after simplification is 24.

The width of a rectangle
is 11 feet longer than the
length. The perimeter of the The rectangle is 70 feet. Find the length and the width.
Answer:
Hello! The answer to this problem is Length= 27 and Width= 8
Step-by-step explanation:
2(11+2x) +2x = 70
6x + 22 = 70
6x = 48
x = 8
Answer:
Length = 23 feet and width = 12 feet.
Step-by-step explanation:
The width (W) = x and the length (L) is x+11 feet (length must be longer than width).
Perimeter = 2W + 2L = 70
2x + 2(x + 11) = 70
2x + 2x + 22 = 70
4x + 22 = 70
4x =- 70 - 22 = 48
x = 12 = width
So length = 12 + 11 = 23.

Answer the question about the angles below.
I need help guys like rn please someone!!
Answer:
B
Step-by-step explanation:
The correct answer is B, because you have -4 +(-6)+(-2) which is really just
-4-6-2 which is -12. Think of it as getting rid of the plus sign and just leaving the negative sign. Which this would make the answer to the equation be -12, but for the answer of the question, it would be B because it is accumulating the drops in temperatures making the numbers go down in temperature, therefore making them negative.
A is not the answer because although it is similar to letter B, the difference is the final sentence, "What was the overall change in temperature?" Since -4 is listed as the pre-existing temperature, that would make -6 - 2 be equal to negative eight (-8).
C is not the answer because it includes a temperature rising by 18 degrees.
D is not the answer either because it is saying the temperature rose, which is shouldn't have risen.
The only time C and D could be right, is if they included bigger number that equaled out to negative twelve (-12), like saying the temperature rose 18 degrees, but fell by 26 degrees by midnight, that would make the equation look like -4 + 18 - 26 = - 12
Even in that case, C and D would be wrong immediately because of the use of numbers outside of the expression given.

If Caleb bought 1.2 pounds of cheese that was selling for 5.95 per pound. How much did Caleb pay for the cheese.
Answer:
$7.14
Step-by-step explanation:
If each pound of cheese is $5.95. You just have to find out how much 1.2 pounds is worth. So, you multiply 5.95 times 1.2 pounds and you'll get $7.14
Multiplication is the process of multiplying. The total amount that Caleb needs to make for 1.2 pounds of cheese at a rate of $5.95 per pound is $7.14.
What is multiplication?Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
Given that the rate of cheese per pound is $5.95 per pound. Therefore, the amount that Caleb needs to make for 1.2 pounds of cheese is,
Total Amount = $5.95/pound × 1.2 pounds
= $7.14
hence, the total amount that Caleb needs to make for 1.2 pounds of cheese at a rate of $5.95 per pound is $7.14.

If ƒ (x ) = 3x2 - x, find ƒ (-2).
I literally have no idea what I'm looking at....maybe I should've paid better attention leading up to the test.

[tex]\\ \rm\longmapsto 12+2[/tex]
[tex]\\ \rm\longmapsto 14[/tex]
Answer:
14
Step-by-step explanation:
f(x) = 3x² - x
To find f(-2), substitute -2 for x into the function f.
f(-2) = 3(-2)² - (-2)Now, use PEMDAS to evaluate the function.
Start by evaluating the exponent.
f(-2) = 3(4) - (-2)Next, multiply 3 and 4 and -2 by -1.
f(-2) = 12 + 2Add the two terms together.
f(-2) = 14The correct answer is f(-2) = 14.

Answer:
BC = 810 KM
Step-by-step explanation:
It is 2/5 from A to C so the remaining distance 1 -2/5 = 5/5 -2/5 = 3/5 is the distance from C to B
BC = 3/5 * 1350

What is the equation of the line that passes through the point (8,1) and has a slope
of –3/4?
Answer:
[tex]y=-\frac{3}{4}x+7[/tex]
Step-by-step explanation:
The slope is already given as [tex]-\frac{3}{4}[/tex] so all we have to do is solve for y-intercept
First, write the equation in slope-intercept form
[tex]y=-\frac{3}{4}x+b[/tex]
Next, use the point to substitute the x and y value and solve for the y-intercept
[tex]y=-\frac{3}{4} x+b[/tex] where b = y-intercept
point: (8, 1)
[tex]1=-\frac{3}{4}(8)+b[/tex]
Then multiply 8 and -3/4
[tex]1=-6+b[/tex]
Finally, solve for the b (y-intercept)
b = [tex]1--6[/tex]
b = 7
so the y-intercept is 7
And the equation of the line that passes through the point (8, 1) and has a slope of -3/4 is [tex]y=-\frac{3}{4}x+7[/tex]

We want to end up with a formula that looks like v1 = algebraic expression
Start by multiplying both sides of the given formula by t, to eliminate fractions:
at = v1 - v0
Next we isolate v1 by adding v0 to both sides of the above equation:
at + v0 = v1 - v0 + v0, or v1 = at + v0
