Correct Answers:

B- using the distributive property, -2 times 5x is -10x, and -2 times -3 is 6. Therefore, an equivalent expression is 8-10+6

E- you can swap 8 to the opposite side of the equation, resulting in -2(5x-3)+8. From here, you distribute and get -10x+6+8. 6+8=14. Therefore, -10x+14 is equivalent.

The ratio of the profit, material cost and production labour of an article is 5:7:13.

IRINA_888 [86]

Answer:

The cost of producing the article is -3500 (Negative cost)

Step-by-step explanation:

The given parameters are

The ratio of the profit to material cost to production labor = 5:7:13

The amount of the material cost = 840 + Labor cost

Let the total cost = X

Therefore, we have;

The fraction of the total cost that is material cost = 7/(5 + 7 + 13) = 7/25

Therefore, the material cost = 7/25 × X

The fraction of the total cost that is labor cost = 13/(5 + 7 + 13) = 13/25

Therefore, the labor cost = 13/25 × X

However, the amount of the material cost = 840 + Labor cost, which gives;

7/25 × X = 13/25 × X + 840

7/25 × X - 13/25 × X = 840

-6/25 × X= 840

X = 840/(-6/25) = 840×(-25/6) = -3500

The cost of producing the article = -3500.

Jane is saving to buy a cell phone. She is given a $100 gift to start and saves me

Dmitriy789 [7]

Answer:

See explanation

Step-by-step explanation:

Jane is given a $100 gift to start and saves $35 a month from her allowance.

After 1 month, Jane has saved $\$100+\$35=\$135;$
After 2 months, Jane has saved $\$100+2\cdot \$35=\$170;$
After three months, Jane has saved $\$100+3\cdot \$35=\$205;$
and so on

In general, after x months Jane has saved

$\$100+x\cdot \$35=\$(100+35x).$

This means that it makes sense to represent the relationship between the amount saved and the number of months with one constant rate (in this case the constant rate is 35). It makes sense because the amount of money increases by $35 each month. Since the amount of increase is constant, we get constant rate. Also the initial amount is known ($100), so there is a possibility to write the equation of linear function representing this situation.
