Yes because when you add a negative, its like subtracting. but when you subtract a negative it becomes a positive, so if you had 10-(-5) it would be the same as 10+5. In this situation, -10+(-5) is the same as -10-5 which makes it equal. Hope this helps.

Yes because they both equal -15 because you actually turn -10+(-5) into a subtraction problem because if there's a + and -, you actually turn it into a minus and the answer is -15.

Darian gets paid $6.35 an hour to help out at his dad's shop. He also mows his neighbor's lawn each week for $25. He earned $119
nevsk [136]
$119.85 is the total amount he earned in 2 weeks
He mows his neighbor's lawn each week for $25...So if he mows for 2 weeks it should be
$25×2=$50
Darian gets paid $6.35 an hour to help out at his dad's shop...
Let X be the number of hours Darian worked at his dad's shop in the two weeks
So we can now make an equation to find X

(X×$6.35)+($25×2)=$119.85
(X×$6.35)+$50=$119.85
X×$6.35=$119.85-$50
X×$6.35=$69.85
X=$69.85÷$6.35
X=11

Therefore the number of hours Darian worked at his dad's shop in those two weeks is 11

Factor 35x + 28y im stuck on this and cannot get the answer
antoniya [11.8K]

Answer:

The answer is 7(5x+4y)

Step-by-step explanation:

Well you would have to first find what number is able to go in both numbers.

7 can go into 35 by 7·5

7 can also go into 28 by 7·4

So now we would simplify this by putting this in a distributive equation.

If you have any questions feel free to ask in the comments - Mark
