44 that's a tricky question at first i thought it was -1 lol
Answer:
Step-by-step explanation:
Using the area model and standard algorithm, we have:
332 (tenths)
<u> × 21 </u>
332
<u> 664 </u>
<u> 6972 </u> tenths = 697.2
<u />
30 + 3 tenths
1 300 32 332
20 600 64 664
33.2 × 21 =<u> 30 </u> × <u> 1 </u> = <u> 30 </u>
A. It is always true
B. -4*6=-24
3*-7=-21
C. Whenever you have a negative being multiplied by a positive the product is always negative
Answer:
The screenshot shows the correct answers; 5x + 5y = 25 is linear.
For a equation to be linear:
- The equation should not have square root, cube root, etc.
- The value of x is not greater than one. X should not have an exponent.
- X is not in a denominator of a fraction.
- "xy" should not be in the equation.
