Answer:
33
Step-by-step explanation:
to solve for each triangle remember its 1/2 base times height you have four of those so add those four sides to the area of the square.
key concept: 1/2(Base*Height)
Answer:
Step-by-step explanation:
NO I FONY FEEL LIKE IT
After 7 days means the temperature has changed 7 times so
7 x (-1.2)
=-8.4°
so the temperature decrease 8.4 degree
Answer:
x = 24/13
General Formulas and Concepts:
<u>Pre-Alg</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
18/13 = 3/4x
<u>Step 2: Solve for </u><em><u>x</u></em>
- Divide both sides by 3/4: x = 24/13
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: 18/13 = 3/4(24/13)
- Multiply: 18/13 = 18/13
Answer:
y = (4/7)X + 22/7
Step-by-step explanation:
Moving from (-2, 2) to (-6, -5), we see that x (the "run") decreases by 4 and y (the "rise") decreases by 7 (from 2 to -5). Thus, the slope is m = rise / run =
-4/(- 7) = 4/7. The slope intercept form y = mx + b takes on the specific values 4/7 for m, 2 for y and -2 for x:
2 = 4/7(-2) + b, or 14 = -8 + 7b. Thus, 22 = 7b, and b = 22/7.
The desired equation is y = (4/7)X + 22/7.
