Answer:

x=-9

Step-by-step explanation:

So, first you do the parentheses, 5(x+2), which comes out to 5x+10, so the equation becomes 5x+10=3x-8. Then, subtract 3x from both sides to get the x's all on one side. (5x-3x)+10=(3x-3x)-8 which equals 2x+10=-8. After that, subtract 10 from both sides to get the numbers all on one side. 2x+(10-10)=(-8-10) which equals 2x=-18. Then, you divide by 2 to get what x equals. (2x/2)=(-18/2) which makes x=-9.

(The work should look like this:)

5(x+2)=3x-8

5x+10=3x-8

2x+10=-8

2x=-18

x=-9

(hope this helps!)

One gallon fills about 231 in3. An aquarium has a height of 15 in. and base measurements 9 in. by 18 in. About how many gallons

SpyIntel [72]

Volume of the fish tank = 15 in × 9 in × 18 in
V = 2430 in³

(2430 in³) ÷ (231 in³ per gallon) = 10.52 gallons

Slope intercept. I keep getting this wrong and idk what I’m doing wrong and if you could explain how you found the points that’d

QveST [7]

Do you mean "write in slope-intercept form"?

In that case: The slope is -3/1 = -3. The y-intercept is where it crosses the y-axis, at -3. The form is y=mx+b, where m is the slope and b is the intercept, so it's y=-3x-3.
