Answer:

How old is he now? eight and one half years ago Steven was 7 years old. How old is he now? 8 1/2+7=15 1/2=31/2 yrs.

Answer:

1. 15 and a half

2. 5 3/5

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

8x+4y-2x+6y-3

combining like terms would give us

6x+10y-3

would is A

Hey there!

8x + 4y - 2x + 6y - 3
COMBINE the LIKE TERMS

= (8x - 2x) + (4y + 6y) - (3)

= 8x - 2x + 4y + 6y - 3

= 6x + 10y - 3

Therefore, your answer is:

6x + 10y - 3 (Optipn A.)

Good luck on your assignment & enjoy your day!

Step-by-step explanation:

DISCOUNT PERCENT = (MP - SP)×100%/MP

= (58-43.50)×100%/ 58

= 14.5×100%/58

=25%

Answer:

2.8

Step-by-step explanation:

Do 0.4 x 3.5 first, that gives you 1.4, then divide that by 0.5, which is 2.8.

Answer:

For a stack of 12 DVD cases, it will be 132mm in height

Step-by-step explanation:

There are 7 cases stacked on top of each other and the total height is 77mm.

Since you must find the height of each individual DVD case you have to divide the height (77mm) by the number of DVD cases (7):

77 / 7 = 11        or       77 ÷ 7 = 11

Then, it asks to find the height of a stack of 12 cases, so take the 11, the height of each DVD case, and multiply it by 12:

11 × 12 = 132

So, the height of 12 DVD cases stacked on top of each other is 132mm.

Answer:

5 + -2= 3

Step-by-step explanation:

the answer is 3 because you have to make zero pairs. the 2 negatives and 2 of the positives make a zero pair, which makes 3 positive ones left so the final answer is 3

Answer:

The whale's elevation is -450. This is because 300 + 150 = 450, making the whale 450 feet below sea level.

Answer:

6 miles

Step-by-step explanation:

A mile is 1760 yards; and hour is 3600 (=2x1800) seconds.

So a yard per second is roughly two miles per hour (actually 1800/1760 x2 miles per hour, so the error is about 40 in 1800 or less than 1 in 40, 2.5%) and three yards per second is about 6 miles per hour. Upper bound of the estimate would be 6 + 2.5% = 6+0.15 = 6.15 mph.

Answer:

To factor out -1/3 out of the expression -1/3x - 8, first divide -8 by -1/3 to get 24. Now just put 24 in the place of -8 in the original expression. Your final answer should be -1/3(x + 24). Hope this helps and have a phenomenal day!

Step-by-step explanation:

Answer:

1/3(x-7)

Step-by-step explanation:

If you divide both the x value (1/3) and the constant value (7/3) by 1/3, you will get 1/3(x-7).

Step-by-step explanation:

Answer:

35.375

Step-by-step explanation:​​

Add −1.5 and 9.5 to get 8.

Multiply 0.4 and 18 to get 7.2.

Expand  −0.2/7.2 ≈−36 by multiplying both numerator and the denominator by 10.

Divide 72 by −2 to get −36.

Convert 36 to fraction 8/288=36.

Subtract 288 from 5 to get −283.

-283/8 =35.375

Answer:

A

Step-by-step explanation:

Lake B's upper quartile is just Lake A's shortest fish. The quartile range is also higher than Lake B. Finally the median, the middle value, is higher than A.

The sum of angles in a triangle is always equal to  180 degrees

Add:

65 + 51 + x + 73 = 180

x + 189 = 180

x = -9      That is fine that x is "-9" because this would just mean that the angle "x+73" is just bigger than it is supposed to be.

Proof:

65 + 51 - 9 + 73 = 180

Therefore, x = -9

Answer:

x = -9

Step-by-step explanation:

Notes to remember:

A triangle's angles will always add up to 180°

--------------------------------------------------------------------

As the image shows, we have two labeled angles. A 51° angle and a 65° angle.

Here's how you want to set up your equation:

180° = 51 + 65 + x + 73

(Rearrange)

180° = 51 + 65 + 73 + x

Add 51, 65, and 73

180° = 189 + x

Subtract 189 from both sides, to isolate x.

-9° = x

ALWAYS PLUG IN (the number that comes from the variable) TO CHECK YOUR WORK!

180° = 51 + 65 - 9 + 73

I hope this helped!

Answer:

Step-by-step explanation:

x+2x-10+x+10=180

(-10+10)(2x+x+x)=180

-20+4x=180

-20+20+4x=180+20

4x=200

4x÷4=200÷4

x=50
