Answer:
21x
Step-by-step explanation:
7x is one term. With parenthesis, you have to multiply whatever is on the outside, inside. So that's 3*7x, or 21x.
Hope this helps!
Hey there!
3(7x)
= 3 * 7x
= 7x * 3
= 7x + 7x + 7x
= 14x + 7x
= 21x
Therefore, the answer should be: 21x

Answer:
x = 26
angle QOR = 31
angle ROS = 59
Step-by-step explanation:
[tex](x + 5) + (2x + 7) = 90\\ 2x + x + 5 + 7 = 90 \\ 3x + 12 = 90 \\ 3x = 90 - 12 \\ 3x = 78 \\ x = 78 \div 3 \\ x = 26[/tex]

Answer:
x < - 25
Step-by-step explanation:
| x + 3 | > 22
Case 1 : x + 3 > 22 [WORKED]
x > 22 - 3
x > 19
Case 2: - (x + 3) > 22
- x - 3 > 22
- x > 22 + 3
x < - 25
As case 1 and 2 don't overlap, so the answer of x should be:
x < - 25 or x > 19

Your Slope-Intercept Form: y=2x-7
1.) Find (0,-7) that shall be your y-intercept.
2.) From your y-intercept [ (0,-7) ] you need to go up 2 and over 1.
**Meaning go up on the y-axis 2 times and go right 1.
Use the Venn diagram to calculate probabilities.
Circles A, B, and C overlap. Circle A contains 3, circle B contains 9, and circle C contains 6. The overlap of A and B contains 1, the overlap of B and C contains 4, and the overlap of C and A contains 7. The overlap of the 3 circles contains 6. Number 8 is outside of the circles.
Which probability is correct?
P(A|B) = One-half
P(B|A) = StartFraction 7 Over 20 EndFraction
P(A|C) = StartFraction 6 Over 23 EndFraction
P(C|A) = StartFraction 13 Over 17 EndFraction
Using the probability concept and the Venn diagram described, the correct option is given by:
P(C|A) = 13/17.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
P(A|B) is given by the sum of the values that involve both A and B by the sum of all values that involve B, hence:
D = 1(overlap of A and B) + 6(Overlap of the 3).T = 9 + 1 + 4 + 6 = 20.Hence:
P(A|B) = 7/20.
Following the same logic, we have that:
P(B|A) = (1 + 6)/(3 + 1 + 7 + 6) = 7/17P(A|C) = (7 + 6)/(6 + 4 + 7 + 6) = 13/23P(C|A) = (7 + 6)/ (3 + 1 + 7 + 6) = 13/17.Hence the last option is correct.

Question 22: 4 pts Find the probability of rolling a 4 on a number cube and then choosing a red ball at random from a bag of 8 blue and 6 red balls.
Answer:
1/14
Step-by-step explanation:
a four out of possible 6 rolls = 1/6
6 red out of 14 balls 6/14
1/6 * 6/14 = 1/14
The Probability of rolling a 4 on a number cube and then choosing a red a ball at random is 1/14.
What is Probability?Probability is "possibility that deals with the chance of occurrence of random event" .
According to the question,
A cube has 6 faces that is (1,2,3,4,5,6). Total number of faces n(s) = 6.
Probability formula = (Number of favorable event)/(Total number of event).
Probability of taking 4, P(4) = 1/6.
A bag containing 8 blue and 6 red balls. Total number of balls in a bag n(s) = 14.
Probability of taking red balls P(red balls) = 6/14.
In order to find that probability of rolling a 4 on a number cube and then choosing a red a ball at random only if multiply P(4) by P(red balls).
P(4) × P(red balls) = [tex]\frac{1}{6}[/tex] × [tex]\frac{6}{14}[/tex] = [tex]\frac{1}{14}[/tex].
Hence, probability of rolling a 4 on a number cube and then choosing a red a ball at random is 1/14.

PQRS is a parallelogram. Angle QSP = 47°. Angle QSR = 24°, PST is a straight line.
Answer:
The value of x = 109°
angle PQS = 24°
Step-by-step explanation:
24° + 47° + x = 180° { angles on straight line }
=> 71 ° + x = 180°
=> x = 180° - 71°
=> x = 109°
Now,
Angle PQS = 24°
angle PQS = angle QSR { alternative angle }
Step-by-step explanation:
a)(i) x=109°
(ii)It's given that PST is straight line then PST=180°,and
PST=QSP+QSR+x
180° =47°+24°+x
180°=71°+x
180°-71°=x
109°=x
b)(i)PQS=71°
(ii)we know opposite angles are equal in parallelogram
so PSR=PQR=71°

The actual height in inches,will be [tex]\dfrac{1}{6} c[/tex] of one of her friends who is c centimeters tall in the picture
What is hieght?Height is measure of vertical distance, either vertical extent (how "tall" something or someone is) or vertical position.
lets call the height x :

In 1900 Kansas City had a population of 163,000In 2020 it has a population of 1,686,000Show me exponential growthHow many years after 1900Did it take for the population to double
The exponential growth is 1.95% and after 35.72 years the population will double.
What is an exponential function?It is defined as the function that rapidly increases and the value of the exponential function is always a positive. It denotes with exponent [tex]\rm y = a^x[/tex]
where a is a constant and a>1
Let's suppose the exponential growth function is:
[tex]\rm y = Ae^{rt}[/tex]
A = 163,000
y = 1,686,000
t = 2020 – 1900 = 120 years
Plug all the values in the function:
[tex]\rm 1686000 = 163000e^{120r}[/tex]
[tex]\rm e^{120r} = 10.343[/tex]
Taking ln both side and solving:
r = 0.0194
r = 1.946 ≈ 1.95%
[tex]\rm 2A = Ae^{0.0194t}[/tex] (the population to double)
After solving:
t = 35.72 years
Thus, the exponential growth is 1.95% and after 35.72 years the population will double.

14 2/3 yards into feet?
Answer:
44.000000001 (exact) or rounded up 44
Step-by-step explanation:
14.666666667*3 because 1 yard= 3 feet
One yard is 3 feet, which means we will have to mutliple 14 2/3 by 3.
14 x 3 =42
2/3 of a yard is 2 feet, which means we must add 2 to 42--->
42+2= 44
14 2/3 yards is 44 feet.
