General Formulas and Concepts:
<u>Pre-Algebra</u>
Step-by-step explanation:
<u>Step 1: Translate</u>
"Five" = 5
"times" is multiplication
"difference" is subtraction
"twice" means 2 times something
"a number" = <em>x</em>
"is" means equal
"-10" = -10
<u>Step 2: Set up equation</u>
5(2x - 4) = -10
<u>Step 3: Solve for </u><em><u>x</u></em>
- Distribute 5: 10x - 20 = -10
- Isolate <em>x </em>term: 10x = 10
- Isolate <em>x</em>: x = 1
Answer:
B
Step-by-step explanation:
To find the slope, find the vertical distance and the horizontal distance between the points. Then write the distances as a ratio.
6 - 3 = 3
0.4 - 0.2 = 0.2
The slope is 3/0.2 = 15.
It would be A and D! hope this helps
3/4=8/x-1
3/4+4/4=8/x
7/4=8/x
7x/4=8
7x=32
x=32/7
