y = 3x+8 5x + 2y =20 solving systems by substitution
Answer:
which grade is that u are doing?
Answer:
x=4/11
y=9 1/11
Step-by-step explanation:
y = 3x+8
5x + 2y =20
5x + 2 (3x+8) =20 .. substitute y
5x + 6x +16 = 20
11x = 20-16 = 4
x = 4/11
Y = 3*4/11 + 8 = 1 1/11 + 8 = 9 1/11

The table below shows the number of times
the arrow stops on each colour.
Pink

94
b) The spinner is spun once more.
Estimate the probability of landing on purple.
c) If the spinner is spun another 1000 times,
about how many times would you expect it to land on blue?
Answer:
A) 60
B) 72/300
C) 150
Step-by-step explanation:
A) P(green) = ⅕
⅕ × 300 = 60
B) purple: 72
45+37+52+94+72 = 300
Therefore, 72/300
C) 1000 × (45/300)
150
a, The number of times is 60.
b. The probability for landing should be [tex]72/300[/tex]
c. The number of times is 150.
Calculation of the number of times and probability:Since
a. The spinner shown is spun 300 times
and, the probability of green should be like [tex]1/5[/tex]
So here one-fifth of 300 should be 60.
b. The probability is
First the total be like
= 45+37+52+94+72
= 300
Now the probability is
= [tex]72/300[/tex]
C) The number of times should be
[tex]= 1000 * (45/300)[/tex]
= 150

Maya makes trail mix by combining 1/2 cup of mixed nuts, 1/4 cup of dried fruit, and 1/8 cup of chocolate morsels. What is the total amount of ingredients in her trail mix? Explain how you solved the problem.
Answer:
7/8 of ingredients
Step-by-step explanation:
To calculate the amount of ingredients in Maya's trail mix, we should first come up with a common denominator to convert all the fractions to.
Our LCD here could be 8, because 8 is divisible by 2 and 4, our other denominators.
1/8 stays as 1/8.
1/2 = 4/8
since 1 x 4 = 4 and 2 x 4 = 8
1/4 = 2/8
since 1 x 2 = 2 and 4 x 2 = 8
1/8 + 4/8 + 2/8 gets us 7/8.
(( I assume you are looking for the total amount in fraction form ))
