Step-by-step explanation:
Let x be the number of helium balloons they can buy
- Write it out: 35 + 3.50x = 125
- Subtract 35 from each side, so it now looks like this: 3.50x = 90
- Divide each side by 3.50 to cancel out the 3.50 next to x. It should now look like this: x =
I hope this helps!
Answer:
y = 20/3
Step-by-step explanation:
4y + 2y + 10 = 50
Combine like terms on the left side.
6y + 10 = 50
Subtract 10 from both sides.
6y = 40
Divide both sides by 6.
y = 40/6
Reduce the fraction by dividing the numerator and denominator by 2.
y = 20/3
Answer:
a = - 25
Step-by-step explanation:
Given that:
4a+6+16=-9(2+12a)-10(1-11a)
By simplifying:
- Adding like terms and multiplying constants into the bracket
- Negative sign will change the signs in the brackets
4a + 22 = -18 - 108a- 10 +110a
4a + 22 = -28 + 2a
- Taking terms with "a" to left side and others to right
- Signs of transferred terms will be changed
4a - 2a = -28 - 22
- Both terms on right side have negative sign so they wil be added and answer will have negative sign.
2a = -50
- Dividing both sides by 2 we get
a = -50/2
- Reducing to lowest term (dividing both by 2)
a = -25/

The average rate of change over an interval is the same as the slope between those two values. The formulate for slope is:
You are given the x values: x2=3 and x1=-9. Plug in these x values to g(x) find the y values:
g(3)=3^2+5(3)-2=9+15-2=22
g(-9)=(-9)^2+5(-9)-2=81-45-2=34
Now, you can solve for m:
m=(22-34)/(3--9)
m=-12/12
m=1
