What is the measure of the angle
Hey! The measure of the angle is 127
The angle is a total of 180 degrees.
We have to find the total of what's in between the two blue lines.
To make it easier, we can take the total of what's not in the blue lines, 53, and subtract it from 180. This gives us 127. So in between both the blue lines, measures 127. Or, you can just count up from 53 to 180 individually.
Who can solve these three ??
Answer:
1) x = 9
2) y = 16
3) y = -1
Step-by-step explanation:
Do PEMDAS in reverse.
For every equation, your goal is to seperate the variable (x,y, or whatever letter) by itself.
1) 2x-7 = 11
Add 7 to both sides.
2x = 18
Divide both sides by 2.
x = 9
2) [tex]\frac{3}{4}y = 12[/tex]
Divide both sides by 3/4 (which turns into multiplying by 4/3).
Left side
[tex]\frac{3}{4}x * \frac{4}{3}\\\\\frac{3}{4}x * \frac{4}{3} = \frac{3*4}{4*3}x\\1x\\x[/tex]
Right side
[tex]12*\frac{4}{3}\\\\\frac{12}{1} *\frac{4}{3}\\\\ \frac{12}{1} *\frac{4}{3} = \frac{12*4}{1*3}\\\\\frac{48}{3} \\16[/tex]
3) 9(y+3) = 18
Remember do PEMDAS in reverse.
Divide both sides by 9.
y+3 = 2
Subtract both sides by 3.
y = -1

Step-by-step explanation:
-5x-9 -4
-5x-9+9 -4+9
-5x 5
-5x/-5x 5/-5
x less than or equal to -1
Answer:
x [tex]\leq[/tex] -1
Step-by-step explanation:
(-5x - 9) [tex]\geq[/tex] -4
add 9 to both sides of the equation
-5x-9 [tex]\geq[/tex] -4
+9 +9
--------------------
the -9 and +9 cancel out
-5x [tex]\geq[/tex] 5
then, divide both sides by -5 to get x
-5x [tex]\geq[/tex] 5
------ -------
-5 -5
x [tex]\leq[/tex] -1
by the way, the sign changed from [tex]\geq[/tex] to [tex]\leq[/tex] because we divided by a negative number to get x.

7x398 thats the questioni need you to answer hahah
Answer:
2,786
Step-by-step explanation:
You can make this easier by taking the expanded form of 398:
300 + 90 + 8
7 x 300 = 2100
7 x 90 = 630
7 x 8 = 56
Then add all these values together:
2100 + 630 + 56 = 2,786
Marlena bought a car in 2010. As years passed, the value of the car decrease linearly, as shown in the table. What was the purchase price of the car in 2010, and how much does it decrease each year?
Answer:
B
Step-by-step explanation:
Difference between value as the years pass, ($22,050-$19,600 = $2,450)
To find purchase price: $22, 050 + $2,450 = $24,500
The sum of three numbers is 66. The second number is twice the first and six less than the third. find the numbers
Step-by-step explanation:
let the 1st number be x
and,
2nd number = 2x
3rd number = 2x + 6
their sum = 66
so, after inserting the values we got
→ x + 2x + 2x + 6 = 66
→ 5x + 6 = 66
→ 5x = 66 - 6 = 60
→ x = 60/5 = 12
→ x = 12
therefore,
1st number = x = 12
2nd number = 2x = 12 × 2 = 24
3rd number = 2x + 6 = 24 + 6 = 30

Point L is located (5,-5) on the coordinate plane. Point L is reflected over y axis to create point L'. What ordered pair describes the location of L'?
Answer:
[tex](-5, -5)[/tex]
Step-by-step explanation:
To reflect a point over the y-axis is the same as flipping the sign of the x-value of the point.
So, point L reflect is [tex](-(5)), -5)=\boxed{(-5, -5)}[/tex].

d=
e=

g=
Answer:
See below
Step-by-step explanation:
a + 54° = 180° [Angles on a straight line]
a = 180 - 54
a = 126°
a + b = 180 [Angles on a straight line add up to 180 degrees]
126 + b = 180
b = 180 - 126
b = 54°
c° = a° [Vertically opposite angles are equal]
c° = 126°
d = 54° [Corresponding angles are equal]
e = a [Corresponding angles are equal]
e = 126°
f = b [Corresponding angles are equal]
f = 54°
g = c [Corresponding angles]
g = 126°

If solving an equation yields a statement that is true for a single value for the variable, like x = 3, then the equation has one solution. If solving an equation yields a statement that is always true, like 3 = 3, then the equation has
5x+3y=-16
-10x-3y=11
Find the solution
Answer: x = 3.2 + 0.6y
Step-by-step explanation: Simplifying
5x + -3y = 16
Solving
5x + -3y = 16
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3y' to each side of the equation.
5x + -3y + 3y = 16 + 3y
Combine like terms: -3y + 3y = 0
5x + 0 = 16 + 3y
5x = 16 + 3y
Divide each side by '5'.
x = 3.2 + 0.6y
Simplifying
x = 3.2 + 0.6y

A shipping container will be used to transport several 150-kilogram crates across the country by rail. The greatest weight that can be loaded into the container is 24000 kilograms. Other shipments weighing 6400 kilograms have already been loaded into the container.
Answer:
[tex]x<=118[/tex]
Step-by-step explanation:
We already have [tex]10300[/tex] kilograms, we will add [tex]x*150[/tex] kilograms, and we need it to be less than or equal to [tex]28000[/tex].
So, the inequality is [tex]150x+10300<=28000[/tex].
We can subtract [tex]10300[/tex] from both sides to get [tex]150x<=17700[/tex].
We then lastly divide by [tex]150[/tex] on both sides to get [tex]x<=118[/tex].
So, the answer is [tex]\boxed{x<=118}[/tex] and we're done!
