Answer:
x = 3, y = 1
Step-by-step explanation:
If your question is this: 2x + 4x + 8y + 16y = 42
6x + 24y = 42
3x + 12y = 21
For x and y are positive integers, there is only 1 set of x = 3 and y = 1 is the solution (because x = 7 and y = 0 is excluded)
check: 6 + 12 + 8 + 16 = 42

Chris has a six sided die. Create a sample
space of possible outcomes for rolling a number. Is this simple or compound event
Answer:
Sample space: {1, 2, 3, 4, 5, 6}
Simple event
Step-by-step explanation:
Sample space is a list of all the possible outcomes.
This is a simple event because you are only doing one event, such as rolling a die.
A compound event would be multiple simple events, such as flipping a coin and choosing a marble from a bag.

7. Angles that are complementary
add up to 90 degrees. If two
complementary angles are in the
ratio of 4:1. how large is the larger
angle?
Answer:
72 degrees is the larger angle
Step-by-step explanation:
SImple ratio problem
So we got a ratio of 4:1 that eqauls to 90 degrees when added up. We can jsut add the 2 numbers 4+1 which will be 5. Now divide 90 by 5 which will equal 18. Now we multiply 18 by each number int he same order of the ratio.
4*18: 1*18
72:18 which equals 90. SInce they ask for the larger angle the answer will be 72.

What is the value of 6(2b-4) when b=5?
Answer:
36
Step-by-step explanation:
Substitute b=5 to the expression:
=6(2(5)−4)
Evaluate inside the parentheses. Multiply 2 and 5 first:
=6(10−4)
Then subtract:
=6(6)
Finally, multiply:
=36
Answer: The value of 6(2b-4) when b=5 is 36.
Step-by-step explanation: Given expression: 6(2b-4). To find the value of 6(2b-4) at b= 5, we need to substitute the b=5 in the expression, we get….Therefore, the value of 6(2b-4) is 36, when b=5.

Use the distributive property to rewrite the expression -1 (x -2)
Answer:
Step-by-step explanation:
Distributive property: a*(b + c) =(a*b) + (a*c)
Multiply x by (-1) and (-2) by (-1)
-1(x - 2 ) = (-1)*x - 2 *(-1)
= -x + 2

Given that ℓ1 ∥ ℓ2 and y = 36°, find x.
x =
Answer:
x = 48
Step-by-step explanation:
From the given diagram, the sum of the angles given is equal to 180 degrees as shown;
x+y+2x = 80
Since y = 36
x +36+2x = 180
3x = 180 - 36
3x = 144
x = 144/3
x = 48
Hence the value of x is 48

The mean of the numbers 22,18,(2y+1),10 and 20 is 15.
find the median.
Answer:
Median is 18
Step-by-step explanation:
Firstly you have to fine y by using your mean
Therefore, 22+18+(2y+1)+10+20 divide it by the number of the mean that is the sum of the number divide by the total number of the mean which is 5 =15
22+18+2y+1+10+20 over 5 =15
71+y over 5 =15
Cross multiple
71+y=75
y=4
22,18,9,10, 20
Rearrange
9,10,18,20,22
The median is 18

During a walk a thon,noahs time in hours was,t,and distance in miles,d,are related by the equation 1/3d=t .A gragh of the equarion includes points (12,4)
Question:
During a walk-a-thon, Noah's time in hours was t, and distance in miles, d, are related by the equation [tex]\frac{1}{3}d = t[/tex]. A graph of the equation includes points (12,4).
1. Identify the independent variable.
2. What does the point (12,4) represent in this situation?
3. What point would represent the time it took to walk [tex]7\frac{1}{2}[/tex] miles?
Answer:
(a) d
(b) He spent 4 hours to walk 12 miles
(c) [tex](7\frac{1}{2},2\frac{1}{2})[/tex]
Step-by-step explanation:
Given
[tex]t = \frac{1}{3}d[/tex]
Solving (a): The independent variable
The independent variable, in this problem is the distance walked. Because the distance walked stands alone, and it is when the distance is known, that the time spent is known.
Hence:
The independent variable is distance (d)
Solving (b): What (12, 4) represents
This implies that:
[tex]distance = 12[/tex]
[tex]time\ spent = 4[/tex]
So: He spent 4 hours to walk 12 miles
Solving (c): Point to represent the time to walk [tex]7\frac{1}{2}[/tex] miles
This implies that:
[tex]d = 7\frac{1}{2}[/tex]
Substitute [tex]d = 7\frac{1}{2}[/tex] in [tex]t = \frac{1}{3}d[/tex]
[tex]t = \frac{1}{3} * 7\frac{1}{2}[/tex]
Express as improper fraction
[tex]t = \frac{1}{3} * \frac{15}{2}[/tex]
[tex]t = \frac{5}{2}[/tex]
Express as mixed number
[tex]t = 2\frac{1}{2}[/tex]
So: The point is, [tex](7\frac{1}{2},2\frac{1}{2})[/tex]
