Answer:
3x - y = -5
<u>-3x -3x</u>
<u>-y</u> = <u>-3x</u> <u>-5</u>
-1 -1 -1
y = 3x + 5
Step-by-step explanation:
- subtract 3x from both sides. 3x cancel 3x, but it can't cancel -5 since it doesn't have any x.
- since y is negative, divide both sides by -1.
- the slope here is 3x, but the slope intercept form is y = 3x + 5
Answer:
28.246
Step-by-step explanation:
hihi. So you can use the Pythagorean theorem to find any missing sides to a triangle. The equation goes like this: a^2 + b^2 = c^2, where a a and b are the lengths of the 2 bases of the triangle and c is the length of the hypothenuse/longest side to the triangle. Since you know the length of the hypothenuse and of one of the bases you can solve for the last base using the equation which gets you ~8.246. Now, adding that to the other side lengths gets you 28.246 as an approximate perimeter to 3 sig figs
Answer:
0.08 pounds per pint.
Step-by-step explanation:
Given: The density of a certain material is such that it weighs 10 ounces per gallon.
We are to express this density in pounds per pint.
1 gallon ⇒ 10 ounces
1 pound = 16 ounces
How many pounds? = 10 ounces.
Cross-multiplying gives;
pounds
1 gallon = 8 pints
The density in pounds per pint is;
0.625 pounds ÷ 8 pints = 0.078125 pounds per pint = 0.08 pounds per pint (answer rounded up to the nearest hundredth).
