What is the value of x in the question 1/2(x+6)=18
Answer: x= 30
Step-by-step explanation:
Simplify both sides of the equation. 12(x+6)=18(12)(x)+(12)(6)=18(Distribute) 1x+3=18
Step 2: Subtract 3 from both sides. 12 x+3−3=18−312 x=15
Step 3: Multiply both sides by 2. 2*(12x)=(2)*(15)
x=30
Answer:
x=30

Marisol is given the following three lengths of a possible triangle: 1, 2 and 7. Would these side lengths form a triangle?
Yes, because 1 + 2 > 7, 2 + 7 > 1 and 7 + 1 > 2.
Yes, because 1 + 2 1 and 7 + 1 is greater than 2.
No, because 1 + 2 < 7 and in order for side lengths to meet the Triangle Inequality Theorem, any two side lengths must be greater than the third side when added together.
Answer:
no because 1+2<7. To form a triangle any two lengths have to be greater than third one

Step-by-step explanation:
Using the diagram above, what is the measure of ∠KPN?
Answer:
∠KPN = 62°
Step-by-step explanation:
If you look at ∠KPO, you can see that it equals 90°
Therefore, ∠KPN and ∠NPO add up to 90°
1. Add both expressions
2x + x- 3 = 90
3x - 3 = 90
2. Add 3 to the 90 to isolate variable x
3x = 93
3. Divide both sides by 3
x = 31
4. Plug in the value for x (31) into ∠KPN
2(31) = 62°

Answer:
42.5 unit²
Step-by-step explanation:
[tex]A_{1}[/tex] = 9 × 3.5 = 31.5
[tex]A_{2}[/tex] = [tex]\frac{2*2}{2}[/tex] = 2
[tex]A_{3}[/tex] = 2² = 4
[tex]A_{4}[/tex] = [tex]\frac{2*5}{2}[/tex] = 5
[tex]A_{1}[/tex] + [tex]A_{2}[/tex] + [tex]A_{3}[/tex] + [tex]A_{4}[/tex] = 42.5 unit²

Change 5x+1=4y+7 to slope intercept form ( y=mx+b)
Answer:
Step-by-step explanation:
5x + 1 = 4y + 7
5x - 4y = 7 - 1
-4y = -5x + 6
-4y/-4 = -5x/-4 + 6/-4
y = 5/4x - 6/4
y = 5/4x - 3/2
Answer:
Work shown below!
Step-by-step explanation:
5x + 1 = 4y + 7 to y = mx + b
5x + 1 = 4y + 7
Subtract 7 from both sides;
5x - 6 = 4y OR 4y = 5x - 6
4y = 5x - 6
Divide both sides by 4;
[tex]y=\frac{5}{4}x-\frac{6}{4} \\\\y=\frac{5}{4}x- \frac{3}{2}[/tex]

A 0.450 L sample of nitrogen gas is collected under a pressure of 2.30 atm and a temperature of 60.0 degrees Celsius. The sample is transferred to a 0.600 L container and the pressure drops to 1.54 atm. What is the new temperature of this gas (in K)?
Answer:
326.56KStep-by-step explanation:
Step one:
Given
V1=0.45L
P1=2.3atm
T1=60 °
V2=0.6L
P2=1.54atm
T2=?
Step two:
Required:
T2
Applying the partial gas formula
[tex]\frac{P1V1}{T1}=\frac{P2V2}{T2}[/tex]
[tex]\frac{2.3*0.45}{60}=\frac{1.54*0.6}{T2}[/tex]
cross multiply we have
T2=(1.54*0.6*60)/2.3*0.45
T2=55.44/1.035
T2=53.56 °
in kelvin, we need to add 273
=273+53.56=326.56K
T2=326.56K
The new temperature of this gas (in K) is 326.56K
