Which numbers are solutions to the inequality x < −7, using the replacement set {−15, −10.5, −7.2, −7, 0}?Choose all answers that are correct.

A.
–7

B.
−7.2

C.
−10.5

D.
−15

Answers

The correct answers are B, -7.2, C, -10.5, and D, -15. The inequality x < -7 means that x is less than -7. Keep in mind that the larger a negative number appears to be, the smaller a number it actually is. For example, if you were 1 dollar in debt, then you would have more money than if you were 100 dollars in debt.

x < -7   Given
-7 < -7   Substitute for answer choice A
This inequality is untrue, because -7 is equal to -7.

-7.2 < -7   Substitute for answer choice B
This inequality is true, because -7.2 is less than -7.

-10.5 < -7   Substitute for answer choice C
This inequality is true, because -10.5 is less than -7.

-15 < -7   Substitute for answer choice D
This inequality is true, because -15 is less than -7.

At one store Julia save $10 with the coupon for 20% off her total purchase at another store the $24 she spent on books is 40% of her total bill how much did Julia spend it all at the two stores

Answers

At the first store, Julia spent 50 dollars. Since 20 percent is 100 divided by 5, you multiply the 10 dollars by 5 to get 50 dollars.

At the second store, Julia spent. Since 12 dollars is 20 percent, multiply 12 dollars by 5 to get 60 dollars.

50+60= 110. Julia spent 110 dollars altogether.

D. because  if you plug the X and Y coordinates into the equation. the equation will always be true
A
-2 = -3 - 5, -2 = -8 is wrong which means A is not the answer

B
-2 = -3 -5, -2 = -8 is wrong which means B is not the answer

C
-8 = -3 - 5, -8 = -8
-5 = 0 - 5, -5 = -5
2 = 3 - 5, 2 = -2 is wrong so C is not the answer

D
-8 = -3 -5, -8 = -8
-5 = 0 - 5, -5 = -5
-2 = 3 - 5, -2 = -2 
All are correct so D is the answer

What 97.645 rounded to the nearest tenth

Answers

97.645.

The tenth digit is 6. The digit after that is 4, and it is not up to 5, so we round it down. If it was up to 5 or more we would have added 1 more to the 6 to become 7, but since it is not up to we leave the 6 that way. 

97.645 ≈ 97.6  rounded to the nearest tenth.
The tenth digit is 6. The number after it is 4. So the 6 stays the same. It is 97.6
