1 answer:
gayaneshka [121]3 years ago
8 0

Answer:

200- (6*19.98)= x; 80.12

Step-by-step explanation:

Sandy has $200. From there, she wrote 6 $19.98 checks. To find what the balance is after you have to find the amount of money she wrote in total on the checks and then subtract it from the original balance in her bank account.

200- (6*19.98)= x

200- 119.88= x

80.12=x

Her account balance is $80.12

You have 8 times as many dimes as nickels. You have 18 dimes
fenix001 [56]

Answer:

$1.70

Step-by-step explanation:

Let the number of nickels be  x.

Thus, by the problem statement, the number of dimes is  [/tex] 8 \cdot x = 8x. [/tex]

Therefore, there are 8x + x = 9 coins in total. To find what x is, we need to solve the equation 9x = 18. This can be done by dividing both sides by 9 which gives x=2. Plugging these values in tells us that there are 2  nickels and 16 dimes. (Test it out!) Thus, the nickels are worth 2 \cdot 5 = 10 cents and the dimes are worth 16 \cdot 10 = 160 cents, so in all, you have 10 + 160 = 170 cents which is $1.70.

Hope this helps :)

Write the inequality for each sentence
liq [111]

Answer:

a) The difference of a number and six is no less than 15

x - 6 ≥ 15

b) 25 plus a number is at least 13

25 + x ≥ 13

c) g decreased by 25 is at most five

g - 25 ≤ 5

Step-by-step explanation:

a) The difference of a number and six is no less than 15

Let the number be represented by x

We difference is involved in a mathematics question, it requires the application of Subtraction operation, hence:

x - 6 ≥ 15

b) 25 plus a number is at least 13

Let the unknown number be represented by x

When at least is used in Mathematics, is means greater than or equal to a particular value,

Hence,

25 + x ≥ 13

c) g decreased by 25 is at most five

At most means less than or equal to a particular value, hence:

g - 25 ≤ 5
