5. If 2x - y = 10 then for x= 8 what is the value of y?a) 7b) 6 C) 5d) 4

1 answer:

6 0

The answer is b, 6

if x=8 then you need to plug in 8 for your in the equation, so you’d have 2(8) - y = 10

you’d get: 16 - y = 10

you’d then subtract 16 from both sides to get -y alone

so now you have -y = -6

you can’t have a -y so you’ll have to divide -1 from both sides

you’ll end up with y=6, which is your answer

At a store, customers are randomly selected to participate in a survey. On Friday, there were 500 customers at the store. Out of

Svetlanka [38]

Divide the number of people selected by the total number of people.

90/500 = .18

This means that 18% of the customers were selected for the survey.

If the probability is the same on Saturday, then we can multiply the expected customers by our .18

700 x .18 = 126

126 should be selected for the survey on Saturday.

Answer:

D. 18.68

Step-by-step explanation:

$27\div \frac{5}{3}-6+53\times (\frac{2}{5})^2$

Applying PEMDAS as order of operations.

Solving the exponents first $[(\frac{2}{5})^2=\frac{4}{25}]$

$=27\div \frac{5}{3}-6+53\times \frac{4}{25}$

Multiplying $[53\times \frac{4}{25}=8.48]$

$=27\div \frac{5}{3}-6+8.48$

Dividing $[27\div \frac{5}{3}=16.2]$

$=16.2-6+8.48$

Adding and subtracting.

$=18.68$

Manuel has $600 in a savings account at the beginning of the summer. He wants to have at least $300 in the account at the end of

stiks02 [169]

The answer to this question is 600-28w > 300. This inequality can be described as $600 (money in the savings account) subtracted by $28w (withdrawal of $28 a week for food) should be greater than $300. It proves that the money will not drop below $300.
