Shalnov [3]1 year ago

Answer:

x = -1/7

Step-by-step explanation:

Solve for x

9-17x-5-4x=7

Combine like terms

-21x +4 = 7

Subtract 4 from each side

-21x-4+4 = 7-4

-21x = 3

Divide each side by -21

-21x/-21 = 3/-21

x = -1/7

Check

9 - 17(-1/7) -5 -4(-1/7) =7

9 + 17/7 -5 + 4/7 =7

4 +21/7 = 7

4+3 = 7

7=7

5 sweets cost 30p altogether, how much do 7 sweets cost?
Nezavi [6.7K]
The best way to find out what 7 sweets cost, firstly, you should find out what one sweet would cost. You have 5 sweets, with a total cost of 30p. You should divide 30 by 5, giving you 6p per sweet. To get the cost of 7 sweets, you have to multiply 6p by 7, giving you 42p. Therefore, the cost of 7 sweets is 42p. Hope this helps :)

1) Emily wants to create snack bags for a trip she is going on. She has 6 granola bars and 10 pieces of dried fruit. If the snac
Kobotan [32]

Answer: 2

Step-by-step explanation:

Given : The number of granola bars = 6

The number of pieces of dried fruit = 10

If the snack bags should be identical without any food left over, then the greatest number of snack bags Emily can make is the greatest common factor (GCF) of 6 and 10.

Since , factors of 6 = 1, 2, 3, 6

Factors of 10 = 1, 2, 5, 10

Hence, the greatest common factor of 6 and 10 = 2

Thus, the greatest number of snack bags Emily can make = 2.
