By what number should you multiply the first equation to solve using elimination?
–3x – 2y = 2
–9x + 3y = 24
–3
6
–9
3
Answer:
3
Step-by-step explanation:
We would be eliminating -9x from the equations.
Thus, we need to make the (-3x) into (-9x) in the first equation.
-9x ÷ -3x = 3
After that, you should be able to solve the equations:
-3x - 2y = 2
Equation 1×3: -9x - 6y = 6
-9x + 3y = 24
Lung cancer may only be caused by first hand smoke. True False
Answer:
No, it could be caused by seocnd hand smokeing also.
Step-by-step explanation:
Answer:
False.
Step-by-step explanation:
Tobacco use not only affects the person using it but also those around them. Secondhand smoke is the smoke that is exhaled by a smoker or that comes from the burning end of a cigarette, cigar, or pipe. Secondhand smoke contains more than 7,000 chemicals, including hundreds that are toxic and at least 70 that can cause cancer. Breathing in secondhand smoke can lead to a range of health problems, especially in children and non-smoking adults. These can include lung cancer, heart disease, stroke, respiratory infections, and asthma. Additionally, exposure to secondhand smoke during pregnancy can cause low birth weight, premature birth, and sudden infant death syndrome (SIDS). Therefore, it is important to create smoke-free environments to protect the health of everyone, including non-smokers.
The three sides of a triangle are in different colors – blue, green and red. The ratio of the length of the blue side to the length of the green side to the length of the red side is 3 : 4 : 5. The perimeter of the triangle is 240 cm. a) Fill in the blank: ___ units = 240 cm b) Fill in the blank: 1 unit = ___ cm c) What is the length of the red side of the triangle?
Answer:
The perimeter is the distance around the triangle. Given the ratio, the perimeter using the ratio is;
= 3 + 4 + 5
= 12 units
a. 12 units = 240 cm
The perimeter in centimetres is 240cm and in ratio is 12 units so they are equivalent.
b. 1 unit = 20 cm
If 12 units are to 240 cm, 1 unit is;
= 240/12
= 20 cm
c. Length of red side;
Red side has length of 5 units. 1 unit is 20 cm.
Length in cm is;
= 5 * 20
= 100 cm

4 cups of peanut butter is needed to make 80 cookies how many cups of peanut butter would be needed to make 400 cookies
Answer:
20 Cups of peanut butter
Step-by-step explanation:
You take 400 divided by 80, which would give you 5, multiply that by the number of cups (4x5) and you final answer will be 20.Answer:
20 cups
Step-by-step explanation:
80 cookies are made by 4 cups
which means 1 cookie is made by
[tex] \frac{4}{80} cups[/tex]
Therefore 400 cookies would require
[tex]400 \times \frac{4}{80} cups = 20cups[/tex]

For f (x), evaluate the following:
a, f(0)
b. f(6)
Show all of your work
Answer:
a). f(0) = 4
b). f(6) = 8
Step-by-step explanation:
a). When x < 5, piecewise function to be considered,
f(x) = x + 4
Since, x = 0 is less than x = 5
f(0) = 0 + 4
f(0) = 4
b). When 5 ≤ x < 7,
Piecewise function to be considered,
f(x) = 8
Therefore, for x = 6,
f(6) = 8
Jason is 10 years older than Alex. Mark is 11 years younger than Alex. If the total of their ages is 68, how old is the youngest of them?
Answer:
Mark is 12 years old.
Step-by-step explanation:
Let's just define some variables:
J = Jason
A = Alex
M = Mark
Next, let's put the information given in the question into equations.
Since Jason is 10 years older than Alex we can represent it like this:
J = A + 10
Since Mark is 11 years younger than Alex we can represent it like this:
M = A - 11
All of their ages add up to 68 so we can represent that like this:
J + A + M = 68
We can now do some substitutions to the J and M in this equation, like this:
(A + 10) + A + (A - 11) = 68
Combine like terms:
3A - 1 = 68
Solve for A
3A = 69
A = 23
Now that we found that Alex is 23 we can plug that back in to the first equations to find their ages:
J = 23 + 10
J = 33
M = 23 - 11
M = 12
Mark is the youngest out of the siblings being 12 years old.
Check:
23 + 33 + 12 = 68
68 = 68 :)
I hope this helps!!

For a crafts fair, Charlie made 25 necklaces with 96 beads in each necklace. Shaniqua made 28 necklaces with 84 beads in each necklace. Who used more beads? _____________________ How many more beads? ____________________
Answer:
A. Charlie
B. Charlie used 48 more beads than Shaniqua
Step-by-step explanation:
Charlie:
25 necklaces with 96 beads in each necklace.
Total beads used = number of beads per necklace × number of necklace
= 96 × 25
= 2,400 beads
Shaniqua:
28 necklaces with 84 beads in each necklace.
Total beads used = number of beads per necklace × number of necklace
= 84 × 28
= 2,352 beads
A. Charlie used more beads
B. 2,400 beads - 2,352 beads= 48 beads
Charlie used 48 more beads than
Shaniqua
Which is a unit rate?
1 Cookie/ 1/3 bag
1 Cookie/ 9 bags
2/3 cookies
3 cookies/bag
Answer:
3 cookies/bag
Step-by-step explanation:
First of all, let's define a unit rate. A unit rate is a ratio of the amount of one measurement to one unit of another measurement term. Unit rates can be expressed as fractions.
Now, here is something easier for you to remember: the second unit always have to be something with the quantity of 1.
In this case, "3 cookies/bag" shows how there are three cookies per, or in each bag--which means 1 bag. The second unit, which is bag, has the quantity of one.

Two brothers, Michael and Alan, were in a bowling league that met once a
week. From past experiences, it is known that both brothers' scores are
approximately normally distributed where Michael has a mean score of 150
with a standard deviation of 30, and Alan has a mean score of 165 with a
standard deviation of 15. Assuming that their scores are independent, which
of the following values is closest to the probability that Michael will have a
greater core than Alan in a single game?
0.16
0.28
0.31
0.33
0.37
Answer:
The correct option is;
0.28
Step-by-step explanation:
The given parameters are;
The mean score for Michael, [tex]\bar x _1[/tex] = 150
The standard deviation, σ₁ = 30
The mean score for Alan, [tex]\bar x _2[/tex] = 165
The standard deviation, σ₂ = 15
Taking n₁ = n₂ = 1
[tex]z=\dfrac{(\bar{x}_{1}-\bar{x}_{2})-(\mu_{1}-\mu _{2} )}{\sqrt{\dfrac{\sigma_{1}^{2} }{n_{1}}-\dfrac{\sigma _{2}^{2}}{n_{2}}}}[/tex]
Taking μ₁ - μ₂ = 0
[tex]z=\dfrac{(150-165)}{\sqrt{\dfrac{30^{2} }{1}-\dfrac{15^{2}}{1}}} \approx -0.577[/tex]
The p-value for a z-score of -0.577 from the z-table is 0.28434
Therefore, the probability that Michael, with mean score, [tex]\bar x _1[/tex] = 150 will have a greater score than Alan, with a mean score of [tex]\bar x _2[/tex] = 165 is 0.28434 ≈ 0.28
Therefore, the correct option is 0.28
