Name a number that has the same absolute value as 23
IRINA_888 [86]

Answer: A number with the same absolute value of 23 is -23.

Explanation: The absolute value of a number is how far it is from zero, and the absolute value of a number is always positive, unless the number is 0, in which case the absolute value is neutral, and the absolute value is 0.

Examples: 6 is 6 away from zero, so the absolute value of 6 is 6.

−6 is 6 away from zero, so the absolute value of −6 is 6.

A truck that can carry no more than 6500 lb is being used to transport refrigerators and upright pianos. Each refrigerator weigh
anyanavicka [17]

Answer:

Equation: 300x+425y= 6500 (if you assume that you would get an exact total)

Answer: Yes, 11 refridgerators and 9 pianos will overload the truck because 11x300=3,300 and 9x425=3,825 which in total equals 7,125, which is way too much for the truck.

An equation that works: 300(10)+425(8)=

Step-by-step explanation:

If each refrigerator is 300 pounds and we need to see if 11 would fit on the truck, multiply 300 times 11 which equals 3,300. Next repeat the same step but for the pianos… 425 times 9 which equals 3,825 now you add. You should get 7,125, meaning this ratio is way to large for the truck to carry.

Since this does not work we should try take away one of each. So let’s say the new rati is 10 refrigerators to 8 pianos. We would repeat the same steps from above. 10x300=3,000       8x425=3,400

If we add these, we get 6,400 so the final expression would be 300(10)+425(8)=6,400 which would be the closest the the most you can transport on the truck.

Sorry if this was not the answer you were looking for, I may have misinterpreted the question.

Five years from now, the sum of the ages of a women and her daughter will be 40 years. The difference in their present age is 24
CaHeK987 [17]

Answer:

Her daughter is <u>3 years</u> old now.

Step-by-step explanation:

Given:

Five years from now, the sum of the ages of a women and her daughter will be 40 years.

The difference in their present age is 24 years.

Now, to find how old is her daughter now.

Let the age of daughter be x\ years.

And the age of mother be y\ years.

According to question:

(x+5)+(y+5)=40

⇒ x+y+10=40

<em>Subtracting both sides by 10 we get:</em>

⇒ x+y=30

⇒ x=30-y............( 1 )

Now, as given in question:

The difference in their present ages is 24 years.

x-y=24

Putting the equation ( 1 ) in the place of x we get:

⇒ (30-y)-y=24

⇒ 30-2y=24

<em>Moving variable on one side and the numbers on the other:</em>

⇒ 30+24=2y

⇒ 54=2y

<em>Dividing both sides by 2 we get:</em>

⇒ 27=y

So, <em>the age of the mother is 27 years.</em>

Now, putting the value of  y in equation( 1 ) we get:

x=30-27

⇒ x=3

<em>The age of daughter is 3 years.</em>

Therefore, her daughter is 3 years old now.

Can someone pls help me with this?
lara [203]

Answer:

14 is A

15 is B

Step-by-step explanation:

14 . the answer is a because first off the slope is negative so we can immediately eliminate B and D second of all the slope is 1/2 so we can eliminate D and get that the answer has to be a

15. answer is B for this one because first of all the slope is negative so we can immediately eliminate A and c and second of all the y-intercept would be 120 because 90 is what x=1 so we would have to add 30 to get what y would equal when x=0 if that makes sense
