You set it up like this.
So quotient means that you're dividing, so put a ÷
Next, it says the dividend, or the part being divided is -8, so now you have this: -8 ÷
Lastly, it says the divisor, or the part doing the dividing, is a quantity equal to the sum of "some number" (we'll use x) and 3. Since the divisor is one quantity collectively, you have to put it in parentheses.
This gives you: (x + 3)
When you put it all together, you get -8 ÷ (x + 3).
This can also be written as a fraction by putting -8 over (x+3).
Answer:
x= -10
Step-by-step explanation:
2x+10=1/2(5x+30)
2x+10=2.5x+15
.5x=-5
5x=-50
x= -10
Answer:
32 small boxes
Step-by-step explanation:
Small: 16 in x 10 in x 7 in
Large: 32 in x 20 in x 14 in
There are 8 small boxes in every large box. So there will be 32 small boxes in 4 large boxes.
Answer: (3 + 0.9)*1 + (3 + 0.9)*0.80
Step-by-step explanation:
We know that each pound cost $1.80 and he buys 3.9 pound.
Then the total cost is:
Cost = $1.80*3.9
And we can write this as:
cost = (1 + 0.80)*(3 + 0.9) = (3 + 0.9)*1 + (3 + 0.9)*0.80
